Losartan Potassium: No significant drug-drug pharmacokinetic interactions have been found in interaction studies with Hydrochlorothiazide, Digoxin, Warfarin, Cimetidine and Phenobarbital. As with other drugs that block angiotensin II or its effects, concomitant use of potassium-sparing diuretics (e.g. Spironolactone, Triamterene, Amiloride), potassium supplements, or salt substitutes containing potassium may lead to increase in serum potassium. As with other antihypertensive agents, the antihypertensive effect of Losartan may be blunted by the non-steroidal anti-inflammatory drug Indomethacin. Hydrochlorothiazide: When administered concurrently, the following drugs may interact with Thiazide diuretics: alcohol, barbiturates, or narcotics-potentiation of orthostatic hypotension may occur. Antidiabetic drugs (oral agents and Insulin): dosage adjustment of the antidiabetic drug may be required. Other antihypertensive drugs: additive effect or potentiation. Cholestyramine and colestipol resins: absorption of Hydrochlorothiazide is impaired in the presence of anionic exchange resins
Therapeutic
Hypersensitivity: Angiooedema Periodic determination of serum electrolytes to detect possible electrolyte imbalance should be performed at appropriate intervals Hypokalemia may rarely develop, especially with brisk diuresis, when severe cirrhosis is present, or after prolonged therapy Impaired renal function and Symptomatic hypotension
Storage Conditions
Use in Patients with Renal Impairment: The usual regimens of therapy with 50/12.5 may be followed as long as the patient's creatinine clearance is >30 ml/min. In patients with more severe renal impairment, loop diuretics are preferred to thiazides. In that case, hydrochlorothiazide is not recommended. Use in Patients with Hepatic Impairment: The combination of Losartan and Hydrochlorothiazide is not recommended for titration in patients with hepatic impairment because the appropriate 25 mg starting dose of Losartan cannot be given. Use in pediatric patients: The safety and effectiveness in pediatric patients have not been established.
