Mild to severe hypertension, Congestive heart failure.
Ramipril is an angiotensin converting enzyme (ACE) inhibitor, which after hydrolysis to ramiprilat, blocks the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. So, inhibition of ACE by ramipril results in decreased plasma angiotensin II, which leads to decreased vasopressor activity and decreased aldosterone secretion. Thus ramipril exerts its antihypertensive activity. It is also effective in the management of heart failure and reduction of the risk of stroke, myocardial infarction and death from cardiovascular events. It is long acting and well tolerated; so, can be used in long term therapy.
Initial dose is 1.25-2.5 mg once daily. Maintenance dosage in adult is 2.5-20 mg daily as single or in 2 divided doses.
Concomitant administration with diuretics may lead to serious hypotension and in addition dangerous hyperkalemia with potassium sparing diuretics. Concomitant therapy with lithium may increase the serum lithium concentration. Reduction in BP may affect the ability to drive and operate machinery and this may be exacerbated by alcohol. NSAIDs may reduce the antihypertensive effect of Ramipril and cause deterioration of renal function.
Hypersensitivity, angioedema.
Dizziness, headache, fatigue & asthenia, hypotension, cough, nausea, vomiting, diarrhoea, rash, urticaria, oliguria, anxiety, amnesia.
Sign and symptom: Overdosage may cause excessive peripheral vasodilatation (with marked hypotension, shock), bradycardia, electrolyte disturbances, and renal failure.
Management: Primary detoxifcation by, for example, gastric lavage, administration of adsorbents, sodium sulfate; (if possible during the frst 30 minutes). In the event of hypotension administration of α1-adrenergic agonists (e.g. norepinephrine, dopamine) or angiotensin II (angiotensinamide), which is usually available only in scattered research laboratories, must be considered in addition to volume and salt substitution.
