About half the absorbed dose of captopril is rapidly metabolized, mainly to captopril-cysteine disulfide and the disulfide dimer of captopril. In vitro studies suggest that captopril and its metabolites may undergo reversible interconversions. It has been suggested that the drug may be more extensively metabolized in patients with renal impairment than in patients with normal renal function.
IDENTIFICATION AND USE: Captopril is angiotensin-converting enzyme (ACE) inhibitor and antihypertensive agent. HUMAN STUDIES: Captopril prevents the conversion of angiotensin I to angiotensin II (a potent vasoconstrictor) by competing with the physiologic substrate (angiotensin I) for the active site of ACE. The affinity of the drug for ACE is approximately 30,000 times greater than that of angiotensin I. Inhibition of ACE results in decreased plasma angiotensin II concentrations and, consequently, blood pressure may be reduced in part through decreased vasoconstriction. Captopril-induced bone marrow suppression is rare, except in certain high-risk patient populations. Severe exfoliative rashes have also been associated with captopril. A 57 year old male with mild impairment of renal function secondary to diabetic glomerulosclerosis developed acute renal failure associated with a generalized desquamative skin rash and peripheral eosinophilia shortly after initiation of antihypertensive therapy with captopril. Cholestatic jaundice is a rare complication associated with the use captopril. The severity of the disease may range from cholestasis on liver histology to overt fulminant hepatic failure. A case of a 75 year old male who committed suicide by taking an overdose of captopril was reported. He took approximately ninety 12.5 mg captopril tablets. Captopril administration over 3 months or more generates red blood cells zinc depletion. Hypogeusia (a reduced ability to taste things) is a reported side effect of captopril. Linkage of hypogeusia to zinc deficiency has been suggested. The fetal toxicity of captopril in the 2nd and 3rd trimesters is similar to other ACE inhibitors. The use of this drug during the 2nd and 3rd trimesters may cause teratogenicity and severe fetal and neonatal toxicity. Fetal toxic effects may include anuria, oligohydramnios, fetal hypocalvaria, intrauterine growth restriction, prematurity, and patent ductus arteriosus. Still birth or neonatal death may occur. Anuria-associated oligohydramnios may product fetal limb contractures, craniofacial deformation, and pulmonary hypoplasia. Sever anuria and hypotension, which is resistant to both pressor agents and volume expansion, may occur in the newborn following in utero exposure. Newborn renal function and blood pressure should be closely monitored. Mutagenicity studies with captopril in fixed combination with hydrochlorothiazide have not been conducted, but the effects of the individual components in a 2:1 ratio have been studied. Captopril/hydrochlorothiazide did not exhibit mutagenic or clastogenic potential in a sister chromatid exchange test in human lymphocytes. In a cytogenetics assay in human lymphocytes exposed to captopril/hydrochlorothiazide concentrations of 5, 25, and 50 ug/mL (total concentration of both drugs) with metabolic activation, chromosomal abnormalities were not observed consistently. When such aberrations were observed, no concentration response was noted. ANIMAL STUDIES: No evidence of carcinogenesis was observed in rats or mice receiving captopril dosages of 50-1350 mg/kg daily for 2 years. Reproduction studies in hamsters and rats using large doses of captopril have not revealed evidence of teratogenic effects. However, the drug was embryocidal and was associated with a low incidence of craniofacial malformations in rabbits, probably as a result of the marked decrease in blood pressure caused by the drug in this species. Reduction in neonatal survival occurred in the offspring of rats receiving captopril continuously during gestation and lactation, and an increased incidence of stillbirths has reportedly occurred in ewes. Mutagenicity studies with captopril in fixed combination with hydrochlorothiazide have not been conducted, but the effects of the individual components in a 2:1 ratio have been studied. Captopril/hydrochlorothiazide did not exhibit mutagenic or clastogenic potential in vitro with or without metabolic activation in a bacterial reverse mutation (Ames) assays using Salmonella, a forward mutation assay in Saccharomyces pombe, and a gene conversion assay using Saccharomyces cerevisiae. Captopril and hydrochlorothiazide in a 2:1 ratio were not genotoxic in the in vivo mouse micronucleus test at an oral dose of 2,500 mg/kg (total concentration of both drugs). ECOTOXICITY STUDIES: Captopril induces oxidative stress in C. carpio.

The drug /captopril/ is metabolized and renally excreted. More than 95% of a dose is excreted renally, both as unchanged (45-50%) drug and as metabolites.
In dogs, approximately 75% of an oral dose is absorbed but food in the GI tract reduces bioavailability by 30-40%. It is distributed to most tissues (not the CNS) and is 40% bound to plasma proteins in dogs.
Approximately 60-75% of an oral dose of captopril is rapidly absorbed from the GI tract in fasting healthy individuals or hypertensive patients. Food may decrease absorption of captopril by up to 25-40%, although there is some evidence that this effect is not clinically important. Following oral administration of a single 100-mg dose of captopril in fasting healthy individuals in one study, average peak blood drug concentrations of 800 ng/mL were attained in 1 hour.
