Precautions

Although the probability of developing hypokalemia is reduced with therapy because of very low dose of HCTZ employed, periodic determination of serum electrolytes should be performed, and patients should be observed for signs of fluid or electrolyte disturbances, eg, hyponatremia, hypochloremic alkalosis, hypokalemia, and hypomagnesemia Thiazides have been shown to increase urinary excretion of magnesium; this may result in hypomagnesemia; warning signs or symptoms of fluid and electrolyte imbalance include dryness of mouth, thirst, weakness, lethargy, drowsiness, restlessness, muscle pains or cramps, muscular fatigue, hypotension, oliguria, tachycardia, and gastrointestinal disturbances such as nausea and vomiting Hypokalemia may develop, especially with brisk diuresis when severe cirrhosis is present, during concomitant use of corticosteroids or adrenocorticotropic hormone (ACTH) or after prolonged therapy; interference with adequate oral electrolyte intake will also contribute to hypokalemia; hypokalemia and hypomagnesemia can provoke ventricular arrhythmias or sensitize or exaggerate the response of the heart to the toxic effects of digitalis; hypokalemia may be avoided or treated by potassium supplementation or increased intake of potassium-rich foods Dilutional hyponatremia may occur in edematous patients in hot weather; appropriate therapy is water restriction rather than salt administration, except in rare instances when hyponatremia is life-threatening; in actual salt depletion, appropriate replacement is therapy of choice Calcium excretion is decreased by thiazides, and pathologic changes in parathyroid glands, with hypercalcemia and hypophosphatemia, have been observed in a few patients on prolonged thiazide therapy Hyperuricemia or acute gout may be precipitated in certain patients receiving thiazide diuretics; bisoprolol fumarate, alone or in combination with HCTZ, has been associated with increases in uric acid; however, in U.S. clinical trials, t

Pregnancy-Lactation

Not Classi Pregnancy There are no adequate and well-controlled studies on pregnant women; therapy should be used during pregnancy only if potential benefit justifies risk to fetus Animal data In rats, bisoprolol fumarate/hydrochlorothiazide (B/H) combination was not teratogenic at doses up to 51.4 mg/kg/day of bisoprolol fumarate in combination with 128.6 mg/kg/day of hydrochlorothiazide; bisoprolol fumarate and hydrochlorothiazide doses used in rat study are, as multiples of MRHD in combination, 129 and 514 times greater, respectively, on a bodyweight basis, and 26 and 106 times greater, respectively, on basis of body surface area The drug combination was maternotoxic (decreased body weight and food consumption) at B5.7/H14.3 (mg/kg/day) and higher, and fetotoxic (increased late resorptions) at B17.1/H42.9 (mg/kg/day) and higher; maternotoxicity was present at 14/57 times MRHD of B/H, respectively, on a bodyweight basis, and 3/12 times MRHD of B/H doses, respectively, on basis of body surface area Fetotoxicity was present at 43/172 times the MRHD of B/H, respectively, on body weight basis, and 9/35 times MRHD of B/H doses, respectively, on basis of body surface area; in rabbits, the B/H combination was not teratogenic at doses of B10/H25 (mg/kg/day); bisoprolol fumarate and hydrochlorothiazide used in rabbit study were not teratogenic at 25/100 times B/H MRHD, respectively, on a bodyweight basis, and 10/40 times B/H MRHD, respectively, on basis of body surface area The drug combination was maternotoxic (decreased body weight) at B1/H2.5 (mg/kg/day) and higher, and fetotoxic (increased resorptions) at B10/H25 (mg/kg/day); the multiples of the MRHD for the B/H combination that were maternotoxic are, respectively, 2.5/10 (on the basis of body weight) and 1/4 (on the basis of body surface area), and for fetotoxicity were, respectively 25/100 (on basis of body weight) and 10/40 (on basis of body surface area) Thiazides cross the placental barrier and appear in the cord blood; the use of thiazides in pregnant women requires that anticipated benefit be weighed against possible hazards to the fetus; these hazards include fetal or neonatal jaundice, pancreatitis, thrombocytopenia, and possibly other adverse reactions that have occurred in the adult See also individual agents Impairment of fertility Reproduction studies in rats did not show impairment of fertility with bisoprolol fumarate/hydrochlorothiazide combination doses containing up to 30 mg/kg/day of bisoprolol fumarate in combination with 75 mg/kg/day of hydrochlorothiazide On a bodyweight basis, these doses are 75 and 300 times, respectively, MRHD of bisoprolol fumarate and hydrochlorothiazide; on body surface area basis, these study doses are 15 and 62 times, respectively, MRHD Lactation Bisoprolol fumarate alone or in combination with HCTZ has not been studied in nursing mothers; thiazides are excreted in human breast milk; small amounts of bisoprolol fumarate(<2% of the dose) have been detected in milk of lactating rats; because of potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or discontinue drug, taking into account importance of drug to mother

Interactions

Bisoprolol : May potentiate AV conduction time and may increase negative inotropic effect w/ class I antiarrhythmic drugs (e.g. quinidine, disopyramide, propafenone). Concomitant catecholamine-depleting drugs (e.g. reserpine, guanethidine) may produce excessive sympathetic activity. May exacerbate rebound HTN upon discontinuance of clonidine treatment. Increased risk of bradycardia w/ digitalis glycosides. Reduced hypotensive effect w/ NSAIDs. Hydrochlorothiazide: Increases toxicity of lithium. May potentiate orthostatic hypotension w/ barbiturates and narcotics. Enhanced neuromuscular blocking action of competitive neuromuscular blockers (e.g. atracurium). Increased hypokalaemic effect w/ corticosteroids, corticotropin, ?2 agonists (e.g. salbutamol). Additive effect w/ other antihypertensives. Potentiation of orthostatic hypotension w/ barbiturates or opioids. Reduced antihypertensive effect by drugs that cause fluid retention (e.g. corticosteroids, NSAIDs, carbenoxolone). Enhanced nephrotoxicity of NSAIDs. Reduced therapeutic effect of antidiabetics.

Mechanism of Action

Bisoprolol fumarate/hydrochlorothiazide is a fixed-combination tablet that combines a Beta adrenergic receptor blocker, bisoprolol fumarate, and a thiazide diuretic, hydrochlorothiazide. Bisoprolol fumarate, a cardioselective inhibitor of beta(1)-adrenoceptor, has no significant intrinsic sympathomimetic activity or membrane stabilizing activity in its therapeutic dosage; exhibits beta(2)-adrenoceptors inhibition and negative chronotropic effect. Hydrochlorothiazide is a thiazide diuretic that inhibits Na reabsorption in distal renal tubules resulting in increased excretion of Na+ and water, also K+ and H+ ions.
