Nutritional complications of capoten - Capoten is used for:

For some of these patients, it may not be possible to normalize blood pressure and maintain adequate renal perfusion. Heart Failure - About 20 percent of patients develop stable elevations of BUN and serum creatinine greater than 20 percent above normal or baseline upon long-term treatment with captopril.

Less than 5 percent of patients, generally those with severe preexisting renal disease, required discontinuation of treatment due to progressively increasing creatinine; subsequent improvement probably depends upon the severity of the underlying renal disease.

Elevations in serum potassium have been observed in some patients treated with ACE inhibitors, including captopril. When treated with ACE inhibitors, patients at risk for the development of hyperkalemia include those with: Presumably due to the inhibition of the degradation of endogenous bradykinin, persistent nonproductive cough has been reported with all ACE inhibitors, always resolving after discontinuation of therapy. ACE inhibitor-induced cough should be considered in the differential diagnosis of cough.

There is concern, on theoretical grounds, that patients with aortic stenosis might be at particular risk of decreased coronary perfusion when treated with vasodilators because they do not develop as much afterload reduction as others.

In patients undergoing major surgery or during anesthesia with agents that produce hypotension, captopril will block angiotensin II formation secondary to compensatory renin release. If hypotension occurs and is considered to be due to this mechanism, it can be corrected by volume expansion.

Hemodialysis Recent clinical observations have shown an association of hypersensitivity-like anaphylactoid reactions during hemodialysis with high-flux dialysis membranes e. In these patients, consideration should be given to using a different type of dialysis membrane or a different class of medication. Anaphylactoid reactions during membrane exposure. The high dose in these studies is times the maximum recommended human dose of mg, assuming a 50 kg subject.

On a body-surface-area basis, the high doses for mice and rats are 13 and 26 times the maximum recommended human dose, respectively. Studies in rats have revealed no impairment of fertility. Nursing Mothers Concentrations of captopril in human milk are approximately one percent of those in maternal blood. Because of the potential for serious adverse reactions in nursing infants from captopril, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of CAPOTEN to the mother.

While captopril may be removed from the adult circulation by hemodialysis, there is inadequate data concerning the effectiveness of hemodialysis for removing it from the circulation of neonates or children. Peritoneal dialysis is not effective for removing captopril; there is no information concerning exchange transfusion for removing captopril form the general circulation.

Safety and effectiveness in pediatric patients have not been established. There is limited experience reported in the literature with the use of captopril in the pediatric population; dosage, on a weight basis, was generally reported to be comparable to or less than that used in adults.

Infants, especially newborns, may be more susceptible to the adverse hemodynamic effects of captopril. Excessive, prolonged and unpredictable decreases in blood pressure and associated complications, including oliguria and seizures, have been reported. CAPOTEN should be used in pediatric patients only if other measures for controlling blood pressure have not been effective. Volume expansion with an intravenous infusion of normal saline is the treatment of choice for restoration of blood pressure.

Peritoneal dialysis is not effective for removing captopril; there is no information concerning exchange transfusion for removing captopril from the general circulation. Its beneficial effects in hypertension and heart failure appear to result primarily from suppression of the renin-angiotensinaldosterone system.

However, there is no consistent correlation between renin levels and response to the drug. Renin, an enzyme synthesized by the kidneys, is released into the circulation where it acts on a plasma globulin substrate to produce angiotensin I, a relatively inactive decapeptide.

Angiotensin I is then converted by angiotensin converting enzyme ACE to angiotensin II, a potent endogenous vasoconstrictor substance. Angiotensin II also stimulates aldosterone secretion from the adrenal cortex , thereby contributing to sodium and fluid retention.

This inhibition has been demonstrated in both healthy human subjects and in animals by showing that the elevation of blood pressure caused by exogenously administered angiotensin I was attenuated or abolished by captopril. In animal studies, captopril did not alter the pressor responses to a number of other agents, including angiotensin II and norepinephrine, indicating specificity of action. Inhibition of ACE results in decreased plasma angiotensin II and increased plasma renin activity PRA , the latter resulting from loss of negative feedback on renin release caused by reduction in angiotensin II.

The reduction of angiotensin II leads to decreased aldosterone secretion, and, as a result, small increases in serum potassium may occur along with sodium and fluid loss. The antihypertensive effects persist for a longer period of time than does demonstrable inhibition of circulating ACE. It is not known whether the ACE present in vascular endothelium is inhibited longer than the ACE in circulating blood.

The presence of food in the gastrointestinal tract reduces absorption by about 30 to 40 percent; captopril therefore should be given one hour before meals. Based on carbon labeling, average minimal absorption is approximately 75 percent. In a hour period, over 95 percent of the absorbed dose is eliminated in the urine; 40 to 50 percent is unchanged drug; most of the remainder is the disulfide dimer of captopril and captopril- cysteine disulfide.

Approximately 25 to 30 percent of the circulating drug is bound to plasma proteins. The apparent elimination half-life for total radioactivity in blood is probably less than 3 hours. An accurate determination of half-life of unchanged captopril is not, at present, possible, but it is probably less than 2 hours. Pharmacodynamics Administration of CAPOTEN results in a reduction of peripheral arterial resistance in hypertensive patients with either no change, or an increase, in cardiac output.

The duration of effect is dose related. The reduction in blood pressure may be progressive, so to achieve maximal therapeutic effects, several weeks of therapy may be required. The blood pressure lowering effects of captopril and thiazide-type diuretics are additive. In contrast , captopril and beta-blockers have a less than additive effect. Blood pressure is lowered to about the same extent in both standing and supine positions. Orthostatic effects and tachycardia are infrequent but may occur in volume-depleted patients.

In patients with heart failure, significantly decreased peripheral systemic vascular resistance and blood pressure afterload , reduced pulmonary capillary wedge pressure preload and pulmonary vascular resistance, increased cardiac output, and increased exercise tolerance time ETT have been demonstrated. These hemodynamic and clinical effects occur after the first dose and appear to persist for the duration of therapy. Placebo controlled studies of 12 weeks duration in patients who did not respond adequately to diuretics and digitalis show no tolerance to beneficial effects on ETT; open studies, with exposure up to 18 months in some cases, also indicate that ETT benefit is maintained.

Clinical improvement has been observed in some patients where acute hemodynamic effects were minimal. The Survival and Ventricular Enlargement SAVE study was a multicenter, randomized, double-blind, placebo-controlled trial conducted in 2, patients age 21 to 79 years who survived the acute phase of myocardial infarction and did not have active ischemia. About half of the patients had symptoms of heart failure in the past. Patients were given a test dose of 6.

Patients were followed for a minimum of two years and for up to five years, with an average follow-up of 3. There was no significant difference between groups in total hospitalizations for all cause placebo; captopril. What makes the body's pancreas? The pancreas consists of 2 parts, one being inside the other. One of the parts, we better known, carries digestive function.

He distinguishes different substances - enzymes, digesting primarily fats and carbohydrates. Violation of the functions of the pancreas associated with inflammation and decrease its production of enzymes, called pancreatitis. It can be acute and chronic.

However, in the framework of diabetes is of little interest to us. Another part of the pancreas is situated in a so-called Islets of Langerhans, it allocates a large number of regulatory substances - hormones. Some of these hormones are responsible for growth and development and more important at a young age. Another part of the hormone itself, is responsible for regulating the level of glucose in the body. Why do we need glucose? Glucose is the main source of energy in the body, feeding it all the cells, tissues and organs, including the brain.

Some drugs may alter gastric acidity and damage mucosal surfaces leading to decreased nutrient absorption. Alterations in appetite may include suppression or stimulation of hunger leading to weight loss or weight gain.

Since many drugs must pass through the liver and kidney upon excretion, hepatotoxicity liver damage and nephrotoxicity kidney damage are of primary concern. Some drugs may affect blood glucose levels by stimulating the production of glucose or inhibiting its uptake. Other drugs may inhibit insulin secretion decrease insulin sensitivity, or increase insulin clearance from the blood.

This may lead to conditions known as hyperglycemia high blood glucose , hypoglycemia low blood glucose , or diabetes. Other medications may lead to abnormal lipid levels, causing elevated cholesterol or triglycerides. Food, Nutrient, and Drug Interactions. This table is intended to be used as a guide only. Consult a doctor or pharmacist with all questions related to your medication. Alcohol can increase the effect of many drugs, and should be avoided with the use of all drugs.
