LOTAS- HT

(Losartan potassium 50 mg + Hydrochlorothiazide 12.5 mg Tablet)

Cardiology

Indications

Hypertension
Hypertension associated with palpitation
Hypertension associated with edema

How it works

Losartan belongs to a group of drugs called angiotensin II receptor antagonists. It keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
Hydrochlorothiazide is a thiazide diuretic often considered the prototypical member of this class. It reduces the reabsorption of electrolytes from the renal tubules. This results in increased excretion of water and electrolytes, including sodium, potassium, chloride, and magnesium. It has been used in the treatment of several disorders including edema, hypertension, diabetes insipidus, and hypoparathyroidism.

Indications

Hypertension
Hypertension associated with palpitation
Hypertension associated with edema

Hydrochlorothiazide
Pregnancy, lactation; intravascular volume depletion.
Pregnancy Category D: There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).
