ensive agents may result in additive hypotension. Dosage adjustments of the antihypertensive medication may be required.
Benazepril: Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor.
Benazepril; Hydrochlorothiazide, HCTZ: Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor.
Benzphetamine: Benzphetamine can increase both systolic and diastolic blood pressure and may counteract the activity of angiotensin II receptor antagonists. This represents a pharmacodynamic, and not a pharmacokinetic, interaction. Close monitoring of blood pressure, especially in patients who are taking antihypertensive agents, may be needed.
Black Cohosh, Cimicifuga racemosa: Actein and certain acids isolated from the rhizome of Cimicifuga spp. have been noted to antagonize the influx of calcium and norepinephrine-induced contraction of the aorta in rats. Black cohosh, Cimicifuga racemosa has potentiated the effects of antihypertensive medications in some animal studies, and actein may have peripheral vasodilatory activity. Clinical reports of interactions between black cohosh and antihypertensive agents in humans are not available, and remain theoretical. However, isolated cases of hypertension or hypotension have been reported with black cohosh use.
Bortezomib: Patients on antihypertensive agents receiving bortezomib treatment may require close monitoring of their blood pressure and dosage adjustment of their medication. During clinical trials of bortezomib, hypotension was reported in roughly 12 percent of patients.
Bosentan: Although no specific interactions have been documented, bosentan has vasodilatory effects and may contribute additive hypotensive effects when given with angiotensin II receptor antagonists. Losartan has no effect on plasma concentrations of bosentan. However, bosentan may theoretically induce the metabolism of losartan via CYP2C9 isoenzymes (clinical significance unknown).
Brexpiprazole: Due to brexpiprazole's antagonism at alpha 1-adrenergic receptors, the drug may enhance the hypotensive effects of alpha-blockers and other antihypertensive agents.
Bromocriptine: Bromocriptine has only minimal affinity for adrenergic receptors; however, hypotension can occur during bromocriptine administration. Orthostatic hypotension occurs in 6% of acromegaly patients receiving the drug. Hypotension occurred frequently (approximately 30%) in postpartum studies, which in rare cases approached a decline in supine pressure of almost 60 mmHg. It is unknown if bromocriptine is the exact cause of this effect. However, the drug should be used cautiously with other medications known to lower blood pressure such as antihypertensive agents. Monitoring of blood pressure should be considered, especially during the initial weeks of concomitant therapy.
Brompheniramine; Carbetapentane; Phenylephrine: The cardiovascular effects of sympathomimetics may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Well-controlled hypertensive patients rec |
