May potentiate hypotensive action w/ diuretics, other antihypertensives, TCAs, nitrates or anaesth. Concomitant admin w/ lithium carbonate may cause lithium toxicity. Increased risk of renal impairment w/ NSAIDs. May increase hyperkalaemic effect w/ K-sparing diuretics and supplements.

Contraindications

History of angioedema due to previous treatment w/ ACE inhibitors. Hereditary or idiopathic angioedema. Pregnancy.

Mechanism of Action

Enalapril, a prodrug of enalaprilat, competitively inhibits ACE from converting angiotensin I to angiotensin II (a potent vasoconstrictor) resulting in increased plasma renin activity and reduced aldosterone (a hormone that causes water and Na retention) secretion. This promotes vasodilation and BP reduction. Onset: Approx 1 hr. Duration: 12-24 hr. Absorption: Well absorbed from the GI tract (approx 60%). Time to peak plasma concentration: Oral: Enalapril: Approx 1 hr; enalaprilat: 3-4 hr. Distribution: Distributed into milk (trace amounts), crosses the placenta and appears to cross the blood-brain barrier poorly. Plasma protein binding: 50-60% (enalaprilat). Metabolism: Extensively hydrolysed to enalaprilat in the liver via esterases. Excretion: Via urine (43% as enalaprilat and 18% as enalapril); faeces (27% as enalaprilat and 6% as enalapril). Elimination half-life: Approx 11 hr.

Special Precautions

Patients w/ bilateral renal artery stenosis or a single kidney w/ unilateral renal artery stenosis, and w/ collagen vascular disease; aortic or mitral valve stenosis. Pre-existing renal insufficiency. Lactation. Monitoring Parameters Monitor BP, and K levels. Correct volume depletion prior to treatment.
