Read moreEnalapril is indicated in- All grades of essential hypertension and renovascular hypertension either alone or in combination with other antihypertensive agents especially thiazide diuretics. Prevention of symptomatic heart failure. Treatment of congestive heart failure (adjunct), usually in combination with diuretics and digitalis. Prevention of coronary ischaemic events in patients with left ventricular dysfunction. Enalapril is also used either alone or as an adjunct in the treatment of angina, diabetic nephropathy and Raynaud's disease.

N/A

Aortic stenosis or outflow tract obstruction. Renovascular disease. Severe resistant HTN. Peripheral vascular disease or generalized atherosclerosis.

Enalapril, after hydrolysis to enalaprilate, inhibits Angiotensin Converting Enzyme (ACE). ACE is a peptidyl dipeptidase that catalyses the conversion of angiotensin I to the vasoconstrictor substance angiotensin II. Angiotensin II also stimulates aldosterone secretion by the adrenal cortex. The beneficial effects of enalapril in hypertension and heart failure appear to result primarily from suppression of the renin-angiotensin aldosterone system

Combination with other antihypertensive agents such as b blockers, Methyldopa, calcium antagonists and diuretics may increase the antihypertensive efficacy. Adrenergic blocking drugs should only be combined with Enalapril under careful supervision. Concomitant Propranolol may reduce the bioavailability of Enalapril, but this does not appear to be of any clinical significance. Concomitant therapy with Lithium may increase the serum Lithium concentration.

Dizziness and headache are more commonly reported side effects. Fatigue and asthenia were reported in 2-3% of patients. Other side effects occurred in less than 2% of patients and included hypotension, orthostatic hypotension, syncope, nausea, diarrhoea, muscle cramps, rash and cough.Less frequently renal dysfunction, renal failure and oliguria have been reported. Angioedema, hyperkalemia and hyponatremia have also been reported rarely

symptoms- Lightheadedness, dizziness, or fainting Decrease in urine output Drowsiness, headache, or back pain Slow or irregular heartbeat. Management- Fluids through an intravenous line (IV) Medications to increase blood pressure Other treatments based on complications that occur Closely monitoring the heart and lungs.
