Interaksi Bisoprolol dan hidroklorotiazid dan Isradipin

Because of the relative beta 1 -selectivity of bisoprolol fumarate, bisoprolol fumarate and hydrochlorothiazide tablets may be used with caution in patients with bronchospastic disease who do not respond to, or who cannot tolerate other antihypertensive treatment.

Drug Interactions Bisoprolol fumarate and hydrochlorothiazide tablets may potentiate the action of other antihypertensive agents used concomitantly.

Bisoprolol fumarate and hydrochlorothiazide tablets 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.

Other antihypertensive drugs - additive effect or potentiation.

Fentanyl Anesthesia: Severe hypotension has been reported during fentanyl anesthesia with concomitant use of a beta blocker and a calcium channel blocker.

Hydrochlorothiazide: A study in normal healthy volunteers has shown that concomitant administration of isradipine and hydrochlorothiazide does not result in altered pharmacokinetics of either drug.

In a study in hypertensive patients, addition of isradipine to existing hydrochlorothiazide therapy did not result in any unexpected adverse effects, and isradipine had an additional antihypertensive effect.
