Examples: Thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blockers, and isoniazid. (Metformin label, Drug interactions)

Drug Interactions When methyldopa is used with other antihypertensive drugs, potentiation of antihypertensive effect may occur. (Methyldopa label, Drug interactions)

Because of its relative beta 1 cardio-selectivity, however, Metoprolol Tartrate Tablets may be used in patients with bronchospastic disease who do not respond to, or cannot tolerate, other antihypertensive treatment. (Metoprolol label, Warnings and precautions)

Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents. (Moexipril label, Warnings)

Drug Interactions: ACE-inhibitors: Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors. (Nabumetone label, Drug interactions)

The blood pressure effect of SULAR tended to be greater in patients on atenolol than in patients on no other antihypertensive therapy. (Nisoldipine label, Drug interactions)

The antihypertensive action of guanethidine and similar agents may be blocked. (Nortriptyline label, Warnings)

These drugs include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blockers, and isoniazid. (Pioglitazone and metformin label, Drug interactions)

Antihypertensive effects of guanethidine and related compounds may be counteracted when phenothiazines are used concomitantly. (Prochlorperazine label, Precautions)

Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents. (Quinapril label, Warnings)

Examples: Atypical antipsychotics (e.g., olanzapine and clozapine), calcium channel antagonists, corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens (e.g., in oral contraceptives), protease inhibitors, somatropin, sympathomimetic agents (e.g., albuterol, epinephrine, terbutaline), and… (Repaglinide label, Drug interactions)

Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents. (Trandolapril label, Warnings)

No other formal drug-drug interaction studies between zafirlukast and marketed drugs known to be metabolized by the P450 3A4 (CYP3A4) isoenzyme (e.g., dihydropyridine calcium-channel blockers, cyclosporin, cisapride) have been conducted. (Zafirlukast label, Precautions)
