Overview
DESCRIPTION Moexipril hydrochloride USP, the hydrochloride salt of moexipril, has the empirical formula C 27 H 34 N 2 O 7 •HCl and a molecular weight of 535.04. It is chemically described as [3S-[2[R*(R*)],3R*]]-2-[2-[[1-(ethoxycarbonyl)-3-phenylpropyl]amino]-1-oxopropyl]- 1,2,3,4-tetrahydro-6,7-dimethoxy-3-iso-quinolinecarboxylic acid, monohydrochloride.
Uses
INDICATIONS AND USAGE Moexipril hydrochloride tablets are indicated for treatment of patients with hypertension. They may be used alone or in combination with thiazide diuretics. In using moexipril hydrochloride tablets, consideration should be given to the fact that another ACE inhibitor, captopril, has caused agranulocytosis, particularly in patients with renal impairment or collagen-vascular disease. Available data are insufficient to show that moexipril hydrochloride tablets do not have a similar risk (see WARNINGS ). In considering use of moexipril hydrochloride tablets, it should be noted that in controlled trials ACE inhibitors have an effect on blood pressure that is less in black patients than in non-blacks.
Dosage
DOSAGE AND ADMINISTRATION Hypertension The recommended initial dose of moexipril hydrochloride tablets in patients not receiving diuretics is 7.5 mg, one hour prior to meals, once daily. Dosage should be adjusted according to blood pressure response. The antihypertensive effect of moexipril hydrochloride tablets may diminish towards the end of the dosing interval. Blood pressure should, therefore, be measured just prior to dosing to determine whether satisfactory blood pressure control is obtained. If control is not adequate, increased dose or divided dosing can be tried. The recommended dose range is 7.5 to 30 mg daily, administered in one or two divided doses one hour before meals. Total daily doses above 60 mg a day have not been studied in hypertensive patients.
Side Effects
ADVERSE REACTIONS Moexipril hydrochloride has been evaluated for safety in more than 2500 patients with hypertension; more than 250 of these patients were treated for approximately one year. The overall incidence of reported adverse events was only slightly greater in patients treated with moexipril hydrochloride than patients treated with placebo. Reported adverse experiences were usually mild and transient, and there were no differences in adverse reaction rates related to gender, race, age, duration of therapy, or total daily dosage within the range of 3.75 mg to 60 mg. Discontinuation of therapy because of adverse experiences was required in 3.4% of patients treated with moexipril hydrochloride and in 1.8% of patients treated with placebo.
Interactions
Drug Interactions Diuretics: Excessive reductions in blood pressure may occur in patients on diuretic therapy when ACE inhibitors are started. The possibility of hypotensive effects with moexipril hydrochloride can be minimized by discontinuing diuretic therapy for several days or cautiously increasing salt intake before initiation of treatment with moexipril hydrochloride. If this is not possible, the starting dose of moexipril should be reduced. (See WARNINGS and DOSAGE AND ADMINISTRATION ). Potassium Supplements and Potassium-Sparing Diuretics: Moexipril hydrochloride can increase serum potassium because it decreases aldosterone secretion.
Warnings
WARNING: FETAL TOXICITY • When pregnancy is detected, discontinue moexipril hydrochloride as soon as possible. • Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus. See WARNINGS: Fetal Toxicity . WARNINGS Anaphylactoid and Possibly Related Reactions Presumably because angiotensin-converting enzyme inhibitors affect the metabolism of eicosanoids and polypeptides, including endogenous bradykinin, patients receiving ACE inhibitors, including moexipril hydrochloride, may be subject to a variety of adverse reactions, some of them serious. Head and Neck Angioedema: Angioedema involving the face, extremities, lips, tongue, glottis, and/or larynx has been reported in patients treated with ACE inhibitors, including moexipril hydrochloride. Symptoms suggestive of angioedema or facial edema occurred in < 0.5% of moexipril-treated patients in placebo-controlled trials. CONTRAINDICATIONS Moexipril hydrochloride is contraindicated in patients who are hypersensitive to this product and in patients with a history of angioedema related to previous treatment with an ACE inhibitor. Do not co-administer aliskiren with moexipril hydrochloride in patients with diabetes (see PRECAUTIONS, Drug Interactions ).
