Norvasc

Her chest pain was due to dog heartworm and Staphylococcus aureus bacteria that originated at teeth #16 quality 5mg norvasc, 17 cheap norvasc 5mg line, 1 norvasc 5 mg cheap, 32. Two weeks later, there was still a little residual heart pain due to Staph; dental work was not yet done. Diabetes Of Childhood The problem is the same for diabetes of childhood as for diabetes of later onset, but much easier to clear up, provided the whole family cooperates. He had pancreatic flukes and their reproductive stages in his pancreas as well as wood al- cohol. Adults who get repeated attacks also have low immunity (this is obvious from a blood test where the white blood cell count is less than 5,000 per cu mm). It is often blamed on promiscuous sex but I believe it has quite dif- ferent origins. I have some evidence that it is released from dog tapeworm stages when these are being killed by your immune system. Herpes lives in your nerve centers (ganglia) and it is from here that you can be attacked after the initial infection. But a meal of aflatoxin or other moldy food suddenly “gags” your white blood cells and lets a viral attack happen. The viruses can also be “triggered” which lets them out of hibernation (latency) to multiply and travel along the nerve fiber to the skin. Triggers are things that put these nerve centers to work: sudden cold and heat, trauma from chafing and friction. Begin your prevention program by raising the immunity of your skin; this means removing all toxins from the skin. Use only natural lotions, softeners, cleansers on your skin made from recipes in this book. This will get rid of nickel, chromate, titanium, zirconium, aluminum, and benzalkonium from your skin and probably your whole body! Do laundry with borax and washing soda, only, to eliminate commercial detergent as a source, too. Attacks probably occur when the triggers act at the same time as an immune drop occurs. When you get an outbreak, mop up a droplet of the blister fluid and prepare it as a specimen for yourself. If you search for it in your white blood cells when your attack is over, it will not be found because it is in hiding inside your nerve cells. Nevertheless, you can totally eliminate them by repeated zapping provided you kill them at their earliest warning. Even after you have been Herpes free for a long time, stick to your preventive principles. Although you may stop the virus in its tracks by zapping, healing the lesion takes time. A lysine mush helps too: crush a lysine table with a large wooden spoon, add a pinch of vitamin C powder and a pinch of zinc oxide. Bazezew Hailey, 38, started breaking out in the genital area after a period of antibiotic use. By the time she had it filled, the next day, her lesion had stopped enlarging, and she could reduce her supplements. Her ratio of segmental to lymphocyte white blood cells was low, evidence for a chronic viral condition. She stopped using tooth- paste (strontium), salt, deodorant, detergents (aluminum). She got the metal out of her mouth and eliminated her radon problem by opening crawl space vents. Fatigue Fatigue, whether minor or extreme, is always associated with blood sugar disturbances. We have three organs that do most of the sugar regu- lating: our adrenals, the liver, and the islets in the pancreas. In severe fatigue, that keeps you partly bedridden, all three organs are heavily parasitized. Killing the viruses is not as important as killing the larger parasites and getting your organs functioning for you again. The adrenals (the outer layer called the cortex) help to regulate the blood sugar in a complex way. The heart of sugar regulation is in your pancreas in the tiny islands of cells that secrete insulin, called the islets of Langer- hans. There is wood alcohol in store-bought drinking water, fruit juice, powders meant to be stirred into bev- erages, even if they are health food varieties. The only beverage you can safely buy (not safe unless you sterilize it, though) at a grocery store is milk. Your first step toward curing your fatigue syndrome is to kill the pancreatic fluke and all other living invaders of the pancreas, liver, adrenals and thyroid. Your energy can bounce back in a few weeks by attending your liver, adrenals and pancreas. Take these supplements for three weeks, then cut the dose in half, and take on alternate days only, as a hedge against possible pollution in these. Although your energy may be normal in three weeks, you are at higher risk for fatigue than the average person. Reinfection with anything will put the new parasites right back where the old ones were. Other bacteria, solvents and toxins will head for the pancreas, liver and adrenals again because these are weakened organs. It could take two years to build your health to its previous level, but is well worth it to have youth, initiative, and a beautiful appearance again. Going back to school is a good use of your time when your initiative has returned but your physical strength is still not up to housework or a job. When your energy comes back to you, it is tempting to overwork: to clean the whole house or to get into some gardening. Our test showed her body was full of bismuth (fragrance) and silver (tooth fillings) especially in the ovaries. She cleansed her kidneys and killed parasites but could not make up her mind to do the expensive dental work. Her skin, kidneys, breasts, brain, ovaries and pancreas were all loaded with mercury, platinum and other metals. Before the moving date arrived she had cleansed kidneys, killed parasites and done dental work and was feeling noticeably better. She immediately was very fatigued again and worried that the move had been in vain. This time she had a liver full of Salmonella and a return of phosphate crystals in her kidneys. But it was easy to clear up and it was a very useful lesson to her to avoid unsterilized dairy products. Her tissues were full of arsenic from pesticide; her urinalysis showed kidney crystals and her eosinophil count was high 5.

The longer the period of unconsciousness discount norvasc 10mg, the greater the risk for pulmonary complications purchase norvasc now. Vital signs and respiratory function are monitored closely to detect any signs of respiratory failure or distress order norvasc online. Total blood count and arterial blood gas measurements are assessed to determine whether there are adequate red blood cells to carry oxygen and whether ventilation is effective. Chest physiotherapy and suctioning are initiated to prevent respiratory complications such as pneumonia. If pneumonia develops, cultures are obtained to identify the organism so that appropriate antibiotics can be administered. Factors that contribute to impaired skin integrity (eg, incontinence, inadequate dietary intake, pressure on bony prominences, edema) are addressed. Care is taken to prevent bacterial contamination of pressure ulcers, which may lead to sepsis and septic shock. Prophylaxis such as subcutaneous heparin or low-molecular-weight heparin (Fragmin, Orgaran) should be prescribed if not contraindicated (Kurtoglu, Yanar, Bilsel, et al. Thigh-high elastic compression stockings or pneumatic compression devices should also be prescribed to reduce the risk for clot formation. Nursing Interventions Maintaining a Patent Airway The patency of the airway is assessed. The patient is hyperoxygenated before and after suctioning to maintain adequate oxygenation. The lung fields are auscultated at least every 8 hours to determine the presence of adventitious sounds or any areas of congestion. Elevating the head of the bed may aid in clearing secretions and improve venous drainage of the brain. Achieving an Adequate Breathing Pattern The patient must be monitored constantly for respiratory irregularities. Increased pressure on the frontal lobes or deep midline structures may result in Cheyne-Stokes respirations, whereas pressure in the midbrain can cause hyperventilation. If the lower portion of the brain stem (the pons and medulla) is involved, respirations become irregular and eventually cease. Repeated assessments of the patient are made (sometimes minute by minute) so that improvement or deterioration may be noted immediately. The head is kept in a neutral (midline) position, maintained with the use of a cervical collar if necessary, to promote venous drainage. Elevation of the head is maintained at 0 to 60 degrees to aid in venous drainage unless otherwise prescribed (Fan, 2004). When moving or being turned in bed, the patient can be instructed to exhale (which opens the glottis) to avoid the Valsalva maneuver. Before suctioning, the patient should be preoxygenated and briefly hyperventilated using 100% oxygen on the ventilator (Hickey, 2003). Corticosteroids may be used to reduce cerebral edema (except when it results from trauma), and fluids may be restricted (Brain Trauma Foundation, 2003). Skin turgor, mucous membranes, urine output, and serum and urine osmolality are monitored to assess fluid status. For the patient receiving mannitol, the nurse observes for the possible development of heart failure and pulmonary edema, because the intent of treatment is to promote a shift of fluid from the intracellular compartment to the intravascular system, thus controlling cerebral edema. For patients undergoing dehydrating procedures, vital signs, including blood pressure, must be monitored to assess fluid volume status. An indwelling urinary catheter is inserted to permit assessment of renal function and fluid status. An output greater than 250 mL/hour for 2 consecutive hours may indicate the onset of diabetes insipidus (Suarez, 2004). These patients also need careful oral hygiene, because mouth dryness occurs with dehydration. Frequently rinsing the mouth with nondrying solutions, lubricating the lips, and removing encrustations relieve dryness and promote comfort. Most health care facilities have written protocols for managing these systems and maintaining their sterility; strict adherence to the protocols is essential. The patient is monitored for signs and symptoms of meningitis: fever, chills, nuchal (neck) rigidity, and increasing or persistent headache. The pulse pressure (the difference between the systolic and the diastolic pressures) widens. Temperature, pulse, and respirations are closely monitored for systemic signs of infection. All connections and stopcocks are checked for leaks, because even small leaks can distort pressure readings and lead to infection. For subsequent pressure readings, the head should be in the same position relative to the transducer. Fiberoptic catheters are calibrated before insertion and do not require further referencing; they do not require the head of the bed to be at a specific position to obtain an accurate reading. Whenever technology is associated with patient management, the nurse must be certain that the technological equipment is functioning properly. The most important concern, however, must be the patient who is attached to the equipment. The patient and family must be informed about the technology and the goals of its use. Diabetes insipidus requires fluid and electrolyte replacement, along with the administration of vasopressin, to replace and slow the urine output. Assessing respiratory function is essential, because even a small degree of hypoxia can increase cerebral ischemia. The respiratory rate and pattern are monitored, and arterial blood gas values are assessed frequently. The nurse must be alert to the development of complications; all assessments are carried out with these problems in mind. Chart 61-2 provides an overview of the nursing management of the patient who has undergone intracranial surgery. Seizures are a potential complication, and any seizure activity is carefully recorded and reported. Restlessness may occur as the patient becomes more responsive, or restlessness may be caused by pain, confusion, hypoxia, or other stimuli. The endotracheal tube is left in place until the patient shows signs of awakening and has adequate spontaneous ventilation, as evaluated clinically and by arterial blood gas analysis. Some degree of cerebral edema occurs after brain surgery; it tends to peak 24 to 36 hours after surgery, producing decreased responsiveness on the second postoperative day. Intraventricular drainage is carefully monitored, using strict asepsis when any part of the system is handled. Overview of Nursing Management for the Patient after Intracranial Surgery Postoperative Interventions Nursing Diagnosis: Risk for ineffective breathing pattern related to postoperative cerebral edema Goal: Achievement of adequate respiratory function Establish proper respiratory exchange to eliminate systemic hypercapnia and hypoxia, which increase cerebral edema. Nursing Diagnosis: Risk for imbalanced fluid volume related to intracranial pressure or diuretics Goal: Attainment of fluid and electrolyte balance Monitor for polyuria, especially during first postoperative week; diabetes insipidus may develop in patients with lesions around the pituitary or hypothalamus.

The vegetable acids may be used in acute disease cheap 10mg norvasc overnight delivery, but are not so good as those named purchase 5 mg norvasc mastercard. It should be prepared by percolation order norvasc 5mg mastercard, the strength being ounce for ounce; though, if constantly made in the office, it will be easier to make it ℥viij, to the pint, the dose being proportionately increased. The medium dose one-third of a drop, and the form of administration: ℞ Tincture of Aconite root, gtt. Aconite is a stimulant to the sympathetic system of nerves, and increases the power of the heart to move the blood, at the same time that it places the blood-vessels in better condition for its passage. It will be recollected that the same system of nerves governs the movements of the heart and of the entire system of blood-vessels. But Aconite is said to be a sedative; and by a sedative we are to understand a remedy that diminishes the frequency of the pulse. There is no doubt but that Aconite is one of the most certain remedies we have to reduce the frequency of the pulse in certain conditions of disease. And the condition is that in which there is a want of power on the part of the heart, and a like want of innervation to the capillary system of blood-vessels. Aconite in small doses lessens the frequency of the pulse, because it removes obstruction to the flow of blood in the vessels, and gives greater cardiac power. We employ it in all forms of fever, to control the circulation, and diminish the temperature. Used in the doses named, it gives greater freedom to the circulation, at the same time that it diminishes the frequency of the pulse. It seems to remove obstruction to the free circulation of the blood, at the same time that it removes irritation of the cardiac nerves, and gives increased power to the heart. It directly antagonizes inflammatory action, and in the early stage will arrest it speedily - if this is the sedative indicated. There are some diseases of an inflammatory character to which Aconite is specific, that deserve mention. In some forms of mucous croup, with enfeebled circulation, in muco-enteritis, and in simple colitis or dysentery from cold, I never think of making any other prescription. As the notice of the action of Aconite in croup may not impress the reader sufficiently, I desire to say that I regard it as the most certain internal remedy in all forms of this disease, and if one cannot find a specific indication for another remedy, let him give this. To point out the special indications for the use of Aconite I can not do better than reproduce the editorial in September Journal of 1868 on the “Differential Therapeutics of Veratrum and Aconite:” To determine which of a class of remedies is applicable in a given case, is the most difficult task of the physician, and any information in this respect is of much value. I doubt whether any one using the two remedies named, would be willing to risk giving this estimate. Many may have an empirical intuition in regard to it, but most could venture nothing but a guess. It is also the remedy where there is an active capillary circulation, both in fever and inflammation. A full and bounding pulse, a full and hard pulse, and a corded or wiry pulse, if associated with inflammation of serous tissues, call for this remedy. Aconite is the remedy when there is difficulty in the capillary circulation, a dilatation and want of tonicity of these vessels, both in fever and inflammation. In general terms, Veratrum is the remedy in sthenia, Aconite in asthenia; but there are too many exceptions to this to make it a safe rule for our guidance. It is the sedative I associate with Belladonna in congestion, especially of the nerve centers, and to relieve coma. Whilst I would use Veratrum with Gelseminum in determination of blood to the brain, and in active delirium. Veratrum acts more efficiently upon the excretory organs; indeed I believe it to be one of the most certain remedies we have to increase excretion. Hence it is employed with great advantage for those purposes usually called alterative. Aconite controls excessive activity of the excretory organs, whether of the bowels, kidneys, or skin. Thus it is our most certain remedy in the summer complaint of children, associated with Belladonna in diabetes insipidus, with the bitter tonics and Strychnia in phosphuria and oxaluria, and with the mineral acids in night sweats. The white cohosh has had but a limited use in medicine, yet it possesses such properties that it will undoubtedly prove useful when studied. The direction of experiment will be to determine its influence on the functions of waste and nutrition, and its special action on the reproductive organs of the female. As you have reached it in your order, you can do as you wish in regard to inserting this. This power in controlling after-pains suggests that it will prove valuable in congestion and neuralgia of the womb. In large doses it is a violent purgative, and may produce inflammation of the bowels. It causes tormina and tenesmus, and seems to extend its influence to all the abdominal viscera, the urinary apparatus included. Its action is attended with unpleasant sensations in the head, and some times it produces severe headache. One ounce of the bark was boiled in a pint and a half of water to one pint, and the whole taken in the course of a day. A tincture may be prepared in the usual way from the bark, and used in doses of from one to thirty drops, as a sedative, diaphoretic and antiperiodic, in the treatment of malarial and other fevers. Take of the recent nuts, fully ripened, four ounces; bruise them thoroughly, and cover with alcohol 76 one pint; let it stand for two weeks; strain and filter. Of this tincture add from one to two drachms to four ounces of water - the dose being one teaspoonful. The buckeye has been used to but a limited extent in medicine, yet its activity is such (as a poison), that it will probably prove very valuable when thoroughly studied. In my boyhood, I well remember persons carrying “buckeyes” in their pockets as a sovereign cure for “piles,” and at a later period as a remedy for rheumatism. It has been used in the treatment of hemorrhoids with much success, and I am satisfied that in some forms of the disease it is the most certain remedy we possess. I have also given it in a few cases of diseased uterus with good results - cases in which the entire organ was enlarged, the cervix tumid, with to frequent recurrence of the menstrual flow. The marked influence of the Æsculus on the nervous system would suggest a line of experiment likely to lead to the development of valuable properties. It has already been employed as a stimulant to the nervous system in some cases of paralysis. We may reason in this way: a remedy that cures hemorrhoids must exert a powerful influence upon the circulation; whilst its poisonous action, often witnessed - vertigo, diminished sight, wry neck, fixed eyes, paralysis, convulsions, etc. The bark of this variety has been employed to a limited extent as a tonic, and possesses feeble antiperiodic powers.

Principal clinical features of the anxiety disorders, post-traumatic stress disorder, and obsessive-compulsive disorder. Generalised anxiety disorder Generalised anxiety disorder is characterised by excessive and inappropriate worrying that is persistent (lasting more than a few months) and not restricted to particular circumstances. Patients have physical anxiety symptoms and key psychological symptoms (restlessness, fatigue, difficulty concentrating, irritability, muscle tension and disturbed sleep). Generalised anxiety disorder is often co-morbid with major depression, panic disor- der, phobic anxiety disorders, health anxiety and obsessive-compulsive disorder. Panic disorder (with or without agoraphobia) Panic disorder is characterised by recurrent unexpected surges of severe anxiety (‘panic attacks’), with varying degrees of anticipatory anxi- ety between attacks. Panic attacks are discrete periods of intense fear or discomfort, accompanied by multiple physical or psychological anxiety symptoms. Around two-thirds of patients with panic disorder develop agoraphobia, defined as fear in places or situations from which escape might be difficult or in which help might not be available, in the event of having a panic attack. These situations include being in a crowd, being outside the home, or using public transport: they are either avoided or endured with significant personal distress. Social phobia (social anxiety disorder) Social phobia is characterised by a marked, persistent and unreasonable fear of being observed or evaluated negatively by other people, in social or performance situations, which is associated with physical and psychological anxiety symptoms. Feared situations (such as speaking to unfamiliar people or eating in public) are either avoided or are endured with significant distress. Specific phobia Specific, simple or isolated phobia is characterised by excessive or unreasonable fear of (and restricted to) single people, animals, objects, or situa- tions (for example, dentists, spiders, lifts, flying, seeing blood) which are either avoided or are endured with significant personal distress.

It is well to keep in mind the fact that this is something more than simply arresting or modifying the septic process purchase generic norvasc from india, for we have already seen that the zymotic influence frequently destroys the life of the fluids and solids without producing putrescency order discount norvasc. We prescribe sulphurous acid as an anti-zymotic in cases which present reddened mucous membranes generic 5mg norvasc with amex, with brownish coatings of tongue and sordes. Given, the indications for the use of an anti-zymotic, with the indications for the use of an acid, and we select the sulphurous acid. Sulphurous acid may be employed in yeasty vomiting, in apthous mouth and throat, or wherever the presence of microscopic fungi is suspected, with the same certainty as the sulphite of soda. We also use it in porrigo, trichosis of scalp, and ptyriasis versicolor, with excellent results. I wish to call especial attention to its use in some diseases of the throat, by the spray or atomizing apparatus. In diphtheria, with dark redness of mucous membranes, and fullness with relaxation, there is no local remedy equal to sulphurous acid spray. It is equally beneficial in those cases of cynanche maligna, with dark redness of mucous membranes. Whilst in ordinary sore throat from cold, with dusky discoloration, it offers one of the best local applications in the materia medica. The Bittersweet has the reputation of being a good alterative, in cutaneous diseases, syphilis, scrofula, and inflammatory deposits, and we conclude that it increases waste and excretion. It exerts a marked influence upon the cerebro-spinal centers, when used in large doses, but this has not been studied. I would advise the employment of the remedy in small doses in those cases of chronic disease in which the circulation is feeble, the hands and feet cold and purplish, with fullness of tissues and tendency to œdema. I do not know that it will prove better than other remedies, but it deserves investigation. Its action is very similar to Belladonna, being a stimulant to the capillary circulation. It may be employed in congestion of the nerve centers, of the abdominal viscera, and of the kidneys. It relieves irritation of stomach and bowels, colic, and is said to promote the menstrual flow. It may be employed as a stimulant to the cerebro-spinal centers, when there is a defect of reflex action, imperfect respiration, and threatened paralysis. It also relieves the excited innervation from atony, and thus gives rest and sleep. It may be used in inflammation of the mouth and throat, and in disease in which this is a continuous complaint, or where there is profuse secretion of saliva (not mercurial. It relieves irritation of the urinary passages, influences the prostate gland, checks gleet and prostatorrhœa, and may be employed in chronic inflammation of the cervix uteri, and in chronic vaginitis with leucorrhœa. I give the formula for the preparation of a tincture of burnt sponge, not because I think it possesses all the properties attributed to it by Homœopaths, but that it may be tested. I have used it in some cases with seeming advantage, and have seen results following its prescription by others, that in the ordinary use of medicine we would call remarkable cures. A quotation from Jahr’s Repertory will show the Homœopathic uses: “Diseases of the lymphatic vessels and glands; heat, with dry, hot skin, thirst, headache and delirium; redness of the eyes, with burning and lachrymation; frequent eructations, with cutting and tearing in the stomach; relaxed feeling in the stomach, as if the stomach were open; orchitis; induration of testes; pain in the larynx on touching it and turning the head; burning in the larynx and trachea; dryness, husky and hoarse voice; inflammation of the larynx, trachea and bronchi; croup; laryngeal and tracheal phthisis; cough, deep from the chest, with soreness and burning, or chronic cough with yellowish expectoration and hoarseness; wheezing inspirations, asthma with amenorrhœa; goitre; hard goitre. The Staphylea has been confounded with the Ptelea, until we hardly know whether a writer in the olden times was describing one or the other. Jones, and valued so highly by him as a tonic, was the article under consideration. At least it would be well for some of our friends who know the article, to procure specimens and thoroughly test it. Jones claimed that it was a pure unirritating tonic, having a soothing influence upon mucous membranes. He employed it in the convalescence from fevers and inflammations, and whenever the stomach was feeble and irritable. The marsh rosemary is an excellent astringent, and at the same time relieves irritation of mucous membranes. It may be used in atonic dyspepsia, in diarrhœa, chronic dysentery, hemorrhage from the lungs, bronchorrhœa, sore throat, chronic laryngitis, and in any catarrhal disease with profuse secretion. Stillingia increases waste and excretion, but its principal action probably is upon the lymphatic system, favoring the formation of good lymph, hence good blood and nutrition. Experience shows that it favorably influences the system in secondary syphilis, in some forms of scrofula, and in cases of chronic disease where the tissues are feeble and not readily removed and renewed. I believe it to be more especially useful in those cases where there is predominant affection of mucous membranes, and secondly, where the skin is involved. In these cases I have used the simple tincture as above, largely diluted with water, with much better results than I have obtained from any of the compounds of Stillingia or alterative syrups. Evidently in the ordinary manufacture of “Compound Syrup of Stillingia,” the virtues of Stillingia, if it has any, are wholly lost, simply because water or dilute alcohol is not a proper menstruum. Stillingia exerts a specific influence upon the mucous membranes of the throat, larynx, and bronchii, relieving irritation and favoring normal nutrition and functional activity. Some cases of chronic pharyngitis of years’ standing, have been relieved by this remedy, after other treatment had failed. It is an excellent remedy in the treatment of some cases of chronic laryngitis, speedily relieving the irritation and cough, and we also employ it in chronic bronchitis with like good results. Now if it is possible to determine the class of cases in which it is thus beneficial, the reader may use it with advantage. So far as my experience extends, they are those with tumid, red, glistening mucous membranes, with scanty secretion. This condition indeed seems to be the index for the use of the remedy for every purpose. From this variety of Lichen, found growing on trees in many parts of the United States, is prepared a tincture in the usual manner. It is a remedy introduced by the Homœopathists, and thus far I have employed their tincture. I have employed it with success in atonic lesions of the respiratory organs, attended with dull pains in the chest, increased by full inspiration. There is also a sense of soreness, as if bruised, or that follows very severe exertion. In these cases it exerted a marked influence, relieving the cough and unpleasant sensations; even checking the chills, hectic fever and night sweats, in confirmed phthisis, for some considerable time. The strongest indication for the Sticta will be found in pain in the shoulders, back of the neck, and extending to the occiput. During the past winter I have had occasion to give it in some very unpleasant cases of scarlet fever, and with most marked benefit. Price, of Baltimore, says: - “I have used Sticta in rheumatism very extensively for the past three or four years. I find it most useful in those cases, where, in connection with the larger joints, the small ones are also involved. It matters not whether fingers or toes, there is swelling, heat, and circumscribed redness of the joints. Both have been employed successfully in the treatment of ague, and are powerful stimulants and restoratives.

During the past two decades, numerous novel oral drug delivery systems, such as mucoadhesives, matrix systems, reservoir systems, microparticulates, and colon- specific drug delivery systems have been developed to overcome some of these limitations. It is appropriate to consider gastrointestinal structure in relation to gastrointestinal function. The function of the digestive system is to break down complex molecules, derived from ingested food, into simple ones for absorption into the blood or the lymph. This process occurs in five main phases, within defined regions of the gastrointestinal system: • ingestion (mouth); • fragmentation (mouth and stomach); • digestion (stomach and small intestine); • absorption (small and large intestine); • elimination of waste products (large intestine). There has recently been considerable interest in this site for the systemic delivery of drug moieties. The possibility of transmucosal delivery via the mucous membranes of the oral cavity is discussed in Chapter 7. The stomach The stomach is a sack that serves as a reservoir for food, where fragmentation is completed and digestion initiated. Digestion is the process by which food is progressively broken down by enzymes into molecules small enough to be absorbed; for example, ingested proteins are initially broken down into polypeptides, then further degraded into oligopeptides and finally into di- and tri-peptides and amino acids, which can be absorbed. Although the stomach does not contribute as much as the small intestine to the extent of drug 133 Figure 6. The small intestine The small intestine, comprising the duodenum, jejunum and ileum, is the principal site for the absorption of digestive products from the gastrointestinal tract. The first 25 cm of the small intestine is the duodenum, the main functions of which are to neutralize gastric acid and pepsin and to initiate further digestive processes. Digestive enzymes from the pancreas (which include trypsin, chymotrypsin, amylase and lipases) together with bile from the liver, enter the duodenum via the common bile duct at the ampulla of Vater (or hepatopancreatic ampulla). Bile contains excretory products of liver metabolism, some of which act as emulsifying agents necessary for fat digestion. The next segment of the small intestine, the jejunum, is where the major part of food absorption occurs. In addition to the great length of the small intestine, the available surface area is further enhanced by the presence of (Figure 6. The large intestine has two main functions: • to absorb water and electrolytes; • to store and eliminate fecal matter. The submucosa This is a layer of loose connective tissue that supports the epithelium and also contains blood vessels, lymphatics and nerves. The muscularis propria This consists of both an inner circular layer and an outer longitudinal layer of smooth muscle and is responsible for peristaltic contraction. The serosa This is an outer layer of connective tissue containing the major vessels and nerves. Four main types of mucosa can be identified, which can be classified according to their main function: • Protective: this is found in the oral cavity, pharynx, esophagus and anal canal. The surface epithelium is stratified squamous and may be keratinized (see Section 1. The mucosa consists of long, closely packed, tubular glands which, depending on the stomach region, secrete mucus, the hormone gastrin and the gastric juices. The intestinal villi are lined by a simple, columnar epithelium which is continuous with that of the crypts. The cells of this epithelium are of two main types: (i) the intestinal absorptive cells (enterocytes), which are tall columnar cells with basally located nuclei; (ii) the mucus-secreting goblet cells, which are scattered among the enterocytes. The mucosa is arranged into closely packed straight glands consisting of cells specialized for water absorption and also mucussecreting goblet cells, which lubricate the passage of feces. Segmentation, tonic contraction, and peristalsis are the three major types of motility patterns observed in the gut. Gastrointestinal, Hepatobiliary, and Nutritional Physiology, Lippincott-Raven, Philadelphia, pp. The Peyer’s patches are found particularly in the distal ileum of the intestinal tract. The epithelium covering the Peyer’s patches comprises specialized antigen-presenting epithelial cells, called M-cells (modified epithelial cells). The uptake and translocation of antigen by the M-cells of Peyer’s patches can be exploited for oral drug and vaccine delivery, as described below (Section 6. It propels intestinal contents, mixes them with digestive juices, and prepares unabsorbed particles for excretion. Gastric motility has been shown to be inhibited by D-glucose in the intestinal fluid. The length of time a drug moiety is in contact with the absorbing tissue will obviously influence the extent of drug absorption. Intestinal motility moves materials in the stomach or small intestine distally towards the large intestine and it has been estimated that in some cases residence of a drug moiety in the small intestine can be in the order of minutes, thereby severely limiting the effective contact time. Following the ingestion of food, the gastric pH rises transiently to 4–5 or higher, but this provokes further acid secretion. Gastric acid is subsequently neutralized by bicarbonates in the duodenum, attaining a value of pH 5. The cecum and the ascending colon are usually more acidic than the small intestine, by one-half to one pH unit, but a higher pH of 6–7 or above is reached more distally. Indeed, inhibition of presystemic metabolic processes is likely to be a factor in a 34% to 103% increase in the bioavailability of nifedipine observed in individuals consuming grapefruit juice. First-pass metabolism in the liver is another important issue for oral drug delivery. This loss of drug from the bloodstream on passage through the liver is termed the first-pass effect. In some cases, the first-pass effect may result in virtually complete elimination of the original drug. Although this is generally disadvantageous for drug delivery, first-pass metabolism can be beneficial for prodrugs, which rely on drug metabolism for activation. Drugs that structurally resemble nutrients such as polypeptides, nucleotides, or fatty acids may be especially susceptible to enzymatic degradation. For example, the proteolytic enzymes chymotrypsin and trypsin can degrade insulin and other peptide drugs. In the case of insulin, proteolysis was shown to be reduced by the coadmmistration of carbopol polymers at 1% and 4% (w/v%), which presumably shifted the intestinal pH away from the optimal pH for proteolytic degradation. Drugs such as erythromycin, penicillin, and omeprazole are unstable in acidic media, and will therefore degrade and provide lower effective doses depending on the gastric pH, drug solubility, and residence time of the dosage form in the stomach. Thus, hydrophobic substrate molecules that enter the membrane lipid bilayer from the lumen will be extracted directly back to the extracelluar medium by the P-glycoprotein, prior to reaching the cell cytoplasm. An alternative model proposes that substrate efflux through the pump (at low substrate concentration) occurs via a four-step mechanism.
