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.

Mode 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.
