Coversyl Plus

Coversyl Plus is indicated in the treatment of essential hypertension where blood pressure is not adequately controlled on perindopril alone.

1-2 tablets per day preferably taken in the morning before a meal. In case of renal insufficiency, treatment should start with an adequate dose.

Side-effects include nausea, vomiting, dyspepsia, diarrhea, constipation, headache, dizziness, sleep disturbance, asthenia, dry mouth, hypotension, persistent dry cough, angioedema, rash.

The drug should be used cautiously in the following situations- in renal impairment, renal artery stenosis, heart failure, gout, diabetes, liver cirrhosis, in elderly patient, atherosclerosis, idiopathic or hereditary angioedema.

Perindopril is a nonsulphydryl ACE inhibitor used in the treatment of hypertension. Following oral administration, perindopril is rapidly hydrolysed to perindoprilat, its principal active metabolite. ACE catalyses the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. Angiotensin II also stimulates aldosterone secretion by the adrenal cortex. Inhibition of ACE activity leads to decreased levels of angiotensin II, thereby resulting in decreased vasoconstriction and decreased aldosterone secretion. The latter change may result in a small increase in serum potassium. Decreased levels of angiotensin II and the accompanying lack of negative feedback on renal renin secretion results in increases in plasma renin activity. Perindopril administration may interfere with the degradation of the vasodepressor peptide bradykinin. It is not known whether this effect contributes to the therapeutic activity of perindopril. The mechanism through which perindopril lowers BP appears to result primarily from suppression of the RAAS.
Indapamide is a sulphonamide derivative with an indole ring, pharmacologically related to the thiazide group of diuretics. Indapamide inhibits the reabsorption of sodium in the cortical diluting segment. It increases the urinary excretion of sodium and chlorides and, to a lesser extent, the excretion of potassium and magnesium, thereby increasing urine output and having an antihypertensive action.
