Angiotensin Converting Enzyme Inhibitor
FDA boxed warning
WARNING: FETAL TOXICITY When pregnancy is detected, discontinue captopril tablets as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus. See WARNINGS: Fetal Toxicity
Hypertension Captopril tablets are indicated for the treatment of hypertension. In using captopril tablets, consideration should be given to the risk of neutropenia/agranulocytosis (see WARNINGS). Captopril tablets may be used as initial therapy for patients with normal renal function, in whom the risk is relatively low. In patients with impaired renal function, particularly those with collagen vascular disease, captopril should be reserved for hypertensives who have either developed unacceptable side effects on other drugs, or have failed to respond satisfactorily to drug combinations. Captopril tablets are effective alone and in combination with other antihypertensive agents, especially thiazide- type diuretics. The blood pressure lowering effects of captopril and thiazides are approximately additive. Heart Failure Captopril tablets are indicated in the treatment of congestive heart failure usually in combination with diuretics and digitalis. The beneficial effect of captopril in heart failure does not require the presence of digitalis, however, most controlled clinical trial experience with captopril has been in patients receiving digitalis, as well as diuretic treatment. …
Patients should be advised to immediately report to their physician any signs or symptoms suggesting angioedema (e.g., swelling of face, eyes, lips, tongue, larynx and extremities; difficulty in swallowing or breathing; hoarseness) and to discontinue therapy (see WARNINGS: Head and Neck Angioedema and Intestinal Angioedema). Patients should be told to report promptly any indication of infection (e.g., sore throat, fever), which may be a sign of neutropenia, or of progressive edema which might be related to proteinuria and nephrotic syndrome. All patients should be cautioned that excessive perspiration and dehydration may lead to an excessive fall in blood pressure because of reduction in fluid volume. Other causes of volume depletion such as vomiting or diarrhea may also lead to a fall in blood pressure; patients should be advised to consult with the physician. Patients should be advised not to use potassium-sparing diuretics, potassium supplements or potassium- containing salt substitutes without consulting their physician (see PRECAUTIONS: General and Drug Interactions; ADVERSE REACTIONS). Patients should be warned against interruption or discontinuation of medication unless instructed by the physician. Heart failure patients on captopril therapy should be cautioned against rapid increases in physical activity. Patients should be informed that captopril tablets should be taken one hour before meals (see DOSAGE AND ADMINISTRATION).
Reported incidences are based on clinical trials involving approximately 7000 patients. Renal About one of 100 patients developed proteinuria (see WARNINGS). Each of the following has been reported in approximately 1 to 2 of 1000 patients and are of uncertain relationship to drug use: renal insufficiency, renal failure, nephrotic syndrome, polyuria, oliguria, and urinary frequency. Hematologic Neutropenia/agranulocytosis has occurred (see WARNINGS). Cases of anemia, thrombocytopenia, and pancytopenia have been repo…
Having one of these?
A doctor will tell you whether it matters and what to do about it. Written answer, a week of free follow-ups.
Ask a doctor — $19.99Captopril tablets are contraindicated in patients who are hypersensitive to this product or any other angiotensin- converting enzyme inhibitor (e.g., a patient who has experienced angioedema during therapy with any other ACE inhibitor). Do not co-administer aliskiren with captopril tablets in patients with diabetes (see PRECAUTIONS: Drug Interactions). Captopril tablets are contraindicated in combination with a neprilysin inhibitor (e.g., sacubitril). Do not administer captopril tablets within 36 hours of switching…
Captopril tablets should be taken one hour before meals. Dosage must be individualized. Hypertension Initiation of therapy requires consideration of recent antihypertensive drug treatment, the extent of blood pressure elevation, salt restriction, and other clinical circumstances. If possible, discontinue the patient’s previous antihypertensive drug regimen for one week before starting captopril tablets. The initial dose of captopril tablets is 25 mg b.i.d. or t.i.d. If satisfactory reduction of blood pressure has n…
Dual Blockade of the Renin-Angiotensin System (RAS) Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. Most patients receiving the combination of two RAS inhibitors do not obtain any additional benefit compared to monotherapy. In general, avoid combined use of RAS inhibitors. Closely monitor blood pressure, renal function and e…
