Known hypersensitivity to the drug. Bilateral renal artery stenosis, hereditary angioedema; renal impairment; pregnancy.
Precautions
Patients on diuretics or with sodium depletion should discontinue diuretics or increase sodium intake prior to initiation of therapy. Renal impairment, SLE and other autoimmune collagen disorders and during concurrent use of immunosuppressant or leucopenic drugs, monitor WBC count and urinary protein before and during therapy. Lactation. Porphyria. Severe CHF.
Discontinue as soon as pregnancy detected; during the second and third trimesters of pregnancy, drugs that act directly on the renin-angiotensin have been associated with fetal injury that includes hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death
Lactation: enters breast milk/not recommended (AAP states compatible with nursing)
Pregnancy-Lactation
Pregnancy Category: C; D in 2nd & 3rd trimesters
Discontinue as soon as pregnancy detected; during the second and third trimesters of pregnancy, drugs that act directly on the renin-angiotensin have been associated with fetal injury that includes hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death
Lactation: enters breast milk/not recommended (AAP states compatible with nursing)
Interactions
Concurrent treatment w/ NSAIDs reduces hypotensive action and increases the risk of nephrotoxicity. Additive hyperkalaemic effect w/ K supplements, K-sparing diuretics, and other drugs (e.g. heparin). May increase risk of leucopenia w/ procainamide, allopurinol, cytostatic or immunosuppressants. May increase risk of lithium toxicity. Increased risk of nitritoid reactions w/ gold (Na aurothiomalate).
Potentially Fatal: Increased risk of hypotension, hyperkalaemia, and changes in renal function (including acute renal failure) w/ aliskiren in diabetic patients.

Potentially Fatal: Neutropenia, usually occurs within 3 mth of starting therapy especially in patients with renal dysfunction or collagen diseases. Hyperkalaemia. Anaphylactic reactions.
Mode of Action
Captopril competitively inhibits the conversion of angiotensin I (ATI) to angiotensin II (ATII), thus resulting in reduced ATII levels and aldosterone secretion. It also increases plasma renin activity and bradykinin levels. Reduction of ATII leads to decreased Na and water retention. This promotes vasodilation and BP reduction.
