Cardobis Plus Tablet 5 mg+6.25 mg

Bisoprolol plus Hydrochlorothiazide is indicated in the treatment of Hypertension.

Bisoprolol Fumarate and Hydrochlorothiazide have been used individually and in combination for the treatment of hypertension. The antihypertensive effects of these agents are additive; Hydrochlorothiazide 6.25 mg significantly increases the antihypertensive effect of Bisoprolol Fumarate. The incidence of hypokalemia with the Bisoprolol Fumarate and Hydrochlorothiazide 6.25 mg combination is significantly lower than with Hydrochlorothiazide 25 mg. Bisoprolol Fumarate is a β1-selective (cardioselective) adrenoceptor blocking agent without significant membrane stabilizing or intrinsic sympathomimetic activities in its therapeutic dose range. Hydrochlorothiazide is a benzothiadiazine diuretic. Thiazides affect renal tubular mechanisms of electrolyte reabsorption and increase excretion of sodium and chloride in approximately equivalent amounts

Bisoprolol is an effective treatment of hypertension in once-daily doses of 2.5 to 40 mg, while Hydrochlorothiazide is effective in doses of 12.5 to 50 mg. In clinical trials of Bisoprolol/Hydrochlorothiazide combination therapy using Bisoprolol doses of 2.5 to 20 mg and Hydrochlorothiazide doses of 6.25 to 25 mg, the antihypertensive effects increased with increasing doses of either component.

Initial Therapy: Antihypertensive therapy may be initiated with the lowest dose of this conbination, one 2.5/6.25 mg tablet once daily. Subsequent titration (14 day intervals) may be carried out with this tablets up to the maximum recommended dose 20/12.5 mg once daily, as appropriate.

Replacement Therapy: The combination may be substituted for the titrated individual components.

Therapy Guided by Clinical Effect: A patient whose blood pressure is not adequately controlled with 2.5-20 mg Bisoprolol daily may instead be given this conbination. Patients whose blood pressures are adequately controlled with 50 mg of hydrochlorothiazide daily, but who experience significant potassium loss with this regimen, may achieve similar blood pressure control without electrolyte disturbance if they are switched to this conbination.

This combination drug may potentiate the action of other antihypertensive agents used concomitantly. This combination drug should not be combined with other beta-blocking agents. Patients receiving catecholamine-depleting drugs, such as reserpine or guanethidine, should be closely monitored because the added beta-adrenergic blocking action of Bisoprolol Fumarate may produce excessive reduction of sympathetic activity. In patients receiving concurrent therapy with clonidine, if therapy is to be discontinued, it is suggested that this combination drug be discontinued for several days before the withdrawal of clonidine. This combination drug should be used with caution when myocardial depressants or inhibitors of AV conduction, such as certain calcium antagonists (particularly of the phenylalkylamine [verapamil] and benzothiazepine [diltiazem] classes) or antiarrhythmic agents, such as disopyramide, are used concurrently. Both digitalis glycosides and beta-blockers slow atrioventricular conduction and decrease heart rate. Concomitant use can increase the risk of bradycardia.

It is contraindicated in patients in cardiogenic shock, overt cardiac failure, second or third degree AV block, marked sinus bradycardia, anuria and hypersensitivity to either component of this product or to other sulfonamide-derived drugs.

Generally well tolerated. Most side effects have been mild and transient. Side effects which may occur: fatigue, dizziness, headache, bradycardia, arrhythmia, peripheral ischemia, chest pain, palpitations, rhythm disturbances, cold extremities, claudication, orthostatic hypotension, diarrhoea, constipation, nausea, dyspepsia, rhinitis, pharyngitis etc.
