What the FDA labels say
From the Bisoprolol and hydrochlorothiazide (bisoprolol fumarate and hydrochlorothiazide) label · effective 2026-08-11
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.
From the Nimodipine (Nymalize) label · effective 2024-08-30
Blood Pressure Lowering Drugs Nimodipine may increase the blood pressure lowering effect of concomitantly administered anti-hypertensives such as diuretics, beta-blockers, ACE inhibitors, angiotensin receptor blockers, other calcium channel blockers, α-adrenergic blockers, PDE5 inhibitors, and α-methyldopa.
Blood pressure should be carefully monitored, and dose adjustment of the blood pressure lowering drug(s) may be necessary.
As a consequence, the blood pressure lowering effect may be increased.
In Europe, nimodipine was observed to occasionally intensify the effect of antihypertensive drugs taken concomitantly by hypertensive patients; this phenomenon was not observed in North American clinical trials.
