(bisoprolol fumarate and hydrochlorothiazide) Tablets
ZIAC® (bisoprolol fumarate and hydrochlorothiazide) is indicated for the treatment of hypertension. It combines two antihypertensive agents in a once-daily dosage: a synthetic betar selective (cardioselective) adrenoceptor blocking agent (bisoprolol fumarate) and a benzothiadiazine diuretic (hydrochlorothiazide).
Bisoprolol fumarate is chemically described as (±)-l-[4-[[2-(l- methylethoxy)ethoxy]methyl]phenoxy]-3-[(l-methylethyl)amino]-2-propanol(E)-2-butenedioate (2:1) (salt). It possesses an asymmetric carbon atom in its structure and is provided as a racemic mixture. The S(-) enantiomer is responsible for most of the beta-blocking activity. Its empirical formula is (C18H31NO4)2•C4H4O4 and it has a molecular weight of 766.97. Its structural formula is:
Bisoprolol fumarate is a white crystalline powder, approximately equally hydrophilic and lipophilic, and readily soluble in water, methanol, ethanol, and chloroform.
Hydrochlorothiazide (HCTZ) is 6-Chloro-3,4-dihydro-2H-l,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. It is a white, or practically white, practically odorless crystalline powder. It is slightly soluble in water, sparingly soluble in dilute sodium hydroxide solution, freely soluble in n-butylamine and dimethylformamide, sparingly soluble in methanol, and insoluble in ether, chloroform, and dilute mineral acids. Its empirical formula is C7H8ClN3O4S2 and it has a molecular weight of 297.73. Its structural formula is:
