इसराडिपिन और प्रोप्रानोलोल का इंटरैक्शन

The concomitant use of beta-adrenergic blockers and non-dihydropyridine calcium channel blockers (e.g., verapamil and diltiazem), digoxin or clonidine increases the risk of significant bradycardia.

Significant increases in AUC (27%) and C max (58%) and decreases in t max (23%) of propranolol were noted in this study.

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

However, concomitant administration of 5 mg b.i.d. isradipine and 40 mg b.i.d. propranolol to healthy volunteers under steady-state conditions had no relevant effect on either drug’s bioavailability.

AUC and C max differences were <20% between isradipine given singly and in combination with propranolol, and between propranolol given singly and in combination with isradipine.

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.
