Severe renal disease, impaired hepatic, allergy or bronchial asthma, systemic lupus erythematosus, acute gout, diabetes mellitus, elderly, collagen vascular diseases, should be discontinued before carrying out tests for parathyroid function. Pregnancy and lactation.
There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
Mode of Action
Ramipril is a long-acting ACE inhibitor which is metabolised into the active metabolite ramiprilat. Supine and standing blood pressures (BP) are reduced witho reflex tachycardia. Ventricular hypertrophy is reversed and renal blood flow increased. In CHF (CHF), pulmonary artery pressure and pulmonary capillary wedge pressure are reduced. Cardiac function is improved. Hydrochlorothiazide is a thiazide diuretic. It increases excretion of Na and chloride in approx equiv amounts. Natriuresis may be accompanied by some loss of K and bicarbonate. The rationale behind this combination is that these have a synergistic effect in lowering BP and offer an advantage of once-daily dosing convenience.
Interaction
Hydrochlorthiazide in combination with alcohol, barbiturates, or narcotics potentiates orthostatic hypotension. When coadministered with other antihypertensive gives additive effect. Absorption is reduced with cholestyramine and colestipol resins. Hypokalemia is observed with corticosteroids, tubocurarine responsiveness to the muscle relaxant is increased. It decreases the renal clearance of lithium and increases the risk of lithium toxicity. Non-steroidal anti-inflammatory agents can reduce the diuretic and natriuretic effect of hydrochlorthiazide.
Ramipril with potassium-sparing diuretics results in severe hyperkaelemia. May increase serum lithium concentration, NSAIDs may reduce the effect of the drug and cause deterioration of renal function.
