🚨 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
🎯 Indications and Usage ▾
INDICATIONS AND USAGE Hypertension: Captopril tablets, USP, are indicated for the treatment of hypertension. In using captopril tablets, USP, consideration should be given to the risk of neutropenia/agranulocytosis (see WARNINGS ). Captopril tablets, USP 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, USP are effective alone and in combination with other antihypertensive agents, especially thiazidetype diuretics. The blood pressure lowering effects of captopril and thiazides are approximately additive.
Heart Failure: Captopril tablets, USP 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. Left Ventricular Dysfunction After Myocardial Infarction: Captopril tablets, USP are indicated to improve survival following myocardial infarction in clinically stable patients with left ventricular dysfunction manifested as an ejection fraction ≤ 40% and to reduce the incidence of overt heart failure and subsequent hospitalizations for congestive heart failure in these patients.
Diabetic Nephropathy: Captopril tablets, USP are indicated for the treatment of diabetic nephropathy (proteinuria > 500 mg/day) in patients with type I insulin-dependent diabetes mellitus and retinopathy. Captopril tablets, USP decreases the rate of progression of renal insufficiency and development of serious adverse clinical outcomes (death or need for renal transplantation or dialysis). In considering use of captopril tablets, USP, it should be noted that in controlled trials ACE inhibitors have an effect on blood pressure that is less in black patients than in non-blacks.
In addition, ACE inhibitors (for which adequate data are available) cause a higher rate of angioedema in black than in non-black patients (see WARNINGS : Head and Neck Angioedema and Intestinal Angioedema ).
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION Captopril tablets, USP 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. The initial dose of captopril tablets, USP is 25 mg twice daily or three times a day. If satisfactory reduction of blood pressure has not been achieved after one week or two weeks, the dose may be increased to 50 mg twice daily or three times a day.
Concomitant sodium restriction may be beneficial when captopril is used alone. The dose of captopril tablets, USP in hypertension usually does not exceed 50 mg three times a day. Therefore, if the blood pressure has not been satisfactorily controlled after one week to two weeks at this dose, (and the patient is not already receiving a diuretic), a modest dose of a thiazide-type diuretic (e.g., hydrochlorothiazide, 25 mg daily), should be added.
The diuretic dose may be increased at one-week to two-week intervals until its highest usual antihypertensive dose is reached. If captopril is being started in a patient already receiving a diuretic, captopril therapy should be initiated under close medical supervision (see WARNINGS and PRECAUTIONS: Drug Interactions regarding hypotension), with dosage and titration of captopril as noted above. If further blood pressure reduction is required, the dose of captopril tablets, USP may be increased to 100 mg twice daily or three times a day and then, if necessary, to 150 mg twice daily or three times a day (while continuing the diuretic).
The usual dose range is 25 mg to 150 mg twice daily or three times a day. A maximum daily dose of 450 mg captopril tablets, USP should not be exceeded. For patients with severe hypertension (e.g., accelerated or malignant hypertension), when temporary discontinuation of current antihypertensive therapy is not practical or desirable, or when prompt titration to more normotensive blood pressure levels is indicated, diuretic should be continued but other current antihypertensive medication stopped and captopril tablets, USP dosage promptly initiated at 25 mg twice daily or three times a day, under close medical supervision.
When necessitated by the patient’s clinical condition, the daily dose of captopril tablets, USP may be increased every 24 hours or less under continuous medical supervision until a satisfactory blood pressure response is obtained or the maximum dose of captopril is reached. In this regimen, addition of a more potent diuretic, e.g., furosemide, may also be indicated. Beta-blockers may also be used in conjunction with captopril therapy (see PRECAUTIONS: Drug Interactions ), but the effects of the two drugs are less than additive.
Heart Failure: Initiation of therapy requires consideration of recent diuretic therapy and the possibility of severe salt/volume depletion. In patients with either normal or low blood pressure, who have been vigorously treated with diuretics and who may be hyponatremic and/or hypovolemic, a starting dose of 6.25 mg or 12.5 mg three times a day may minimize the magnitude or duration of the hypotensive effect (see WARNINGS: Hypotension ); for these patients, titration to the usual daily dosage can then occur within the next several days.
For most patients the usual initial daily dosage is 25 mg three times a day. After a dose of 50 mg three times a day is reached, further increases in dosage should be delayed, where possible, for at least two weeks to determine if a satisfactory response occurs. Most patients studied have had a satisfactory clinical improvement at 50 mg or 100 mg three times a day.
A maximum daily dose of 450 mg of captopril tablets should not be exceeded. Captopril should generally be used in conjunction with a diuretic and digitalis…
⛔ Contraindications ▾
CONTRAINDICATIONS Captopril is 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 in patients with diabetes (see PRECAUTIONS , Drug Interactions ). Captopril is contraindicated in combination with a neprilysin inhibitor (e.g., sacubitril).
Do not administer captopril within 36 hours of switching to or from sacubitril/valsartan, a nepriltsin inhibitor (see PRECAUTIONS , Drug Interactions ).
⚠️ Warnings ▾
WARNINGS Anaphylactoid and Possibly Related Reactions Presumably because angiotensin-converting enzyme inhibitors affect the metabolism of eicosanoids and polypeptides, including endogenous bradykinin, patients receiving ACE inhibitors (including captopril) may be subject to a variety of adverse reactions, some of them serious. Head and Neck Angioedema: Angioedema involving the extremities, face, lips, mucous membranes, tongue, glottis or larynx has been seen in patients treated with ACE inhibitors, including captopril.
If angioedema involves the tongue, glottis or larynx, airway obstruction may occur and be fatal. Emergency therapy, including but not necessarily limited to, subcutaneous administration of a 1:1,000 solution of epinephrine should be promptly instituted. Swelling confined to the face, mucous membranes of the mouth, lips and extremities has usually resolved with discontinuation of captopril; some cases required medical therapy.
(See PRECAUTIONS : Information for Patients and ADVERSE REACTIONS . ) Patients receiving coadministration of ACE inhibitor and mTOR (mammalian target of rapamycin) inhibitor (e.g., temsirolimus, sirolimus, everolimus) therapy or a neprilysin inhibitor may be at increased risk for angioedema (see PRECAUTIONS , Drug Interactions ). Intestinal Angioedema: Intestinal angioedema has been reported in patients treated with ACE inhibitors. These patients presented with abdominal pain (with or without nausea or vomiting); in some cases there was no prior history of facial angioedema and C-1 esterase levels were normal.
The angioedema was diagnosed by procedures including abdominal CT scan or ultrasound, or at surgery, and symptoms resolved after stopping the ACE inhibitor. Intestinal angioedema should be included in the differential diagnosis of patients on ACE inhibitors presenting with abdominal pain. Anaphylactoid reactions during desensitization: Two patients undergoing desensitizing treatment with hymenoptera venom while receiving ACE inhibitors sustained life-threatening anaphylactoid reactions.
In the same patients, these reactions were avoided when ACE inhibitors were temporarily withheld, but they reappeared upon inadvertent rechallenge. Anaphylactoid reactions during membrane exposure: Anaphylactoid reactions have been reported in patients dialyzed with high-flux membranes and treated concomitantly with an ACE inhibitor. Anaphylactoid reactions have also been reported in patients undergoing low-density lipoprotein apheresis with dextran sulfate absorption.
Neutropenia/Agranulocytosis Neutropenia (< 1,000/mm 3 ) with myeloid hypoplasia has resulted from use of captopril. About half of the neutropenic patients developed systemic or oral cavity infections or other features of the syndrome of agranulocytosis. The risk of neutropenia is dependent on the clinical status of the patient: In clinical trials in patients with hypertension who have normal renal function (serum creatinine less than 1.6 mg/dL and no collagen vascular disease), neutropenia has been seen in one patient out of over 8,600 exposed.
In patients with some degree of renal failure (serum creatinine at least 1.6 mg/dL) but no collagen vascular disease, the risk of neutropenia in clinical trials was about 1 per 500, a frequency over 15 times that for uncomplicated hypertension. Daily doses of captopril were relatively high in these patients, particularly in view of their diminished renal function. In foreign marketing experience in patients with renal failure, use of allopurinol concomitantly with captopril has been associated with neutropenia but this association has not appeared in U.S. reports.
In patients with collagen vascular diseases (e.g., systemic lupus erythematosus, scleroderma) and impaired renal function, neutropenia occurred in 3.7 percent of patients in clinical trials. While none of the over 750 patients in formal clinical trials of heart failure developed neutropenia, it has occurred during the subsequent clinica…
🤒 Adverse Reactions ▾
ADVERSE REACTIONS Reported incidences are based on clinical trials involving approximately 7,000 patients. Renal : About one of 100 patients developed proteinuria (see WARNINGS ). Each of the following has been reported in approximately 1 to 2 of 1,000 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 reported. Dermatologic : Rash, often with pruritus, and sometimes with fever, arthralgia, and eosinophilia, occurred in about 4 to 7 (depending on renal status and dose) of 100 patients, usually during the first four weeks of therapy.
It is usually maculopapular, and rarely urticarial. The rash is usually mild and disappears within a few days of dosage reduction, short-term treatment with an antihistaminic agent, and/or discontinuing therapy; remission may occur even if captopril is continued. Pruritus, without rash, occurs in about 2 of 100 patients.
Between 7 percent and 10 percent of patients with skin rash have shown an eosinophilia and/or positive ANA titers. A reversible associated pemphigoid-like lesion, and photosensitivity, have also been reported. Flushing or pallor has been reported in 2 to 5 of 1,000 patients.
Cardiovascular : Hypotension may occur; see WARNINGS and PRECAUTIONS [Drug Interactions] for discussion of hypotension with captopril therapy. Tachycardia, chest pain, and palpitations have each been observed in approximately 1 of 100 patients. Angina pectoris, myocardial infarction, Raynaud’s syndrome, and congestive heart failure have each occurred in 2 to 3 of 1,000 patients.
Dysgeusia : Approximately 2 to 4 (depending on renal status and dose) of 100 patients developed a diminution or loss of taste perception. Taste impairment is reversible and usually self-limited (2 months to 3 months) even with continued drug administration. Weight loss may be associated with the loss of taste.
Angioedema : Angioedema involving the extremities, face, lips, mucous membranes, tongue, glottis or larynx has been reported in approximately one in 1,000 patients. Angioedema involving the upper airways has caused fatal airway obstruction. (See WARNINGS: Head and Neck Angioedema , Intestinal Angioedema and PRECAUTIONS: Information for Patients . ) Cough: Cough has been reported in 0.5% to 2% of patients treated with captopril in clinical trials (see PRECAUTIONS: General , Cough).
The following have been reported in about 0.5 percent to 2 percent of patients but did not appear at increased frequency compared to placebo or other treatments used in controlled trials: gastric irritation, abdominal pain, nausea, vomiting, diarrhea, anorexia, constipation, aphthous ulcers, peptic ulcer, dizziness, headache, malaise, fatigue, insomnia, dry mouth, dyspnea, alopecia, paresthesias. Other clinical adverse effects reported since the drug was marketed are listed below by body system. In this setting, an incidence or causal relationship cannot be accurately determined.
Body as a whole : Anaphylactoid reactions (see WARNINGS: Anaphylactoid and possible related reactions and PRECAUTIONS: Hemodialysis ). General: Asthenia, gynecomastia . Cardiovascular: Cardiac arrest, cerebrovascular accident/insufficiency, rhythm disturbances, orthostatic hypotension, syncope .
Dermatologic : Bullous pemphigus, erythema multiforme (including Stevens-Johnson syndrome), exfoliative dermatitis. Gastrointestinal : Pancreatitis, glossitis, dyspepsia. Hematologic : Anemia, including aplastic and hemolytic.
Hepatobiliary : Jaundice, hepatitis, including rare cases of necrosis, cholestasis. Metabolic : Symptomatic hyponatremia. Musculoskeletal : Myalgia, myasthenia.
Nervous/Psychiatric : Ataxia, confusion, depression, nervousness, somnolence. Respiratory : Bronchospasm, eosinophilic pneumonitis, rhinitis. Special Senses : Blurred visio…
🆘 Overdosage ▾
OVERDOSAGE Correction of hypotension would be of primary concern. Volume expansion with an intravenous infusion of normal saline is the treatment of choice for restoration of blood pressure. 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 from the general circulation.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Mechanism of Action The mechanism of action of captopril has not yet been fully elucidated. Its beneficial effects in hypertension and heart failure appear to result primarily from suppression of the renin-angiotensin-aldosterone 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.
Captopril prevents the conversion of angiotensin I to angiotensin II by inhibition of ACE, a peptidyldipeptide carboxy hydrolase. 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.
ACE is identical to ''bradykininase'', and captopril may also interfere with the degradation of the vasodepressor peptide, bradykinin. Increased concentrations of bradykinin or prostaglandin E 2 may also have a role in the therapeutic effect of captopril. 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.
Pharmacokinetics After oral administration of therapeutic doses of captopril, rapid absorption occurs with peak blood levels at about one hour. The presence of food in the gastrointestinal tract reduces absorption by about 30 percent to 40 percent; captopril therefore should be given one hour before meals. Based on carbon-14 labeling, average minimal absorption is approximately 75 percent.
In a 24-hour period, over 95 percent of the absorbed dose is eliminated in the urine; 40 percent to 50 percent is unchanged drug; most of the remainder is the disulfide dimer of captopril and captopril-cysteine disulfide. Approximately 25 percent 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. In patients with renal impairment, however, retention of captopril occurs (see DOSAGE AND ADMINISTRATION ). Pharmacodynamics Administration of captopril results in a reduction of peripheral arterial resistance in hypertensive patients with either no change, or an increase, in cardiac output.
There is an increase in renal blood flow following administration of captopril and glomerular filtration rate is usually unchanged. Reductions of blood pressure are usually maximal 60 minutes to 90 minutes after oral administration of an individual dose of captopril. 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 bet…
