            Pregnancy Category: C (1st trimester); D (2nd & 3rd trimester)

            Lactation: inconclusive evidence exists, use caution

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            Pharmacology

            Mechanism of Action

            Moexipril/hydrochlorothiazide is a fixed-combination tablet that combines an angiotensin-converting enzyme (ACE) inhibitor, moexipril, and a thiazide diuretic, hydrochlorothiazide

            Moexipril prevents the conversion of angiotensin I to angiotensin II (a potent vasoconstrictor) through inhibition of ACE by competing with physiologic substrate (angiotensin I) for active site of ACE; inhibition of ACE initially results in decreased plasma angiotensin II concentrations & consequently, blood pressure may be reduced in part through decreased vasoconstriction, increased renin activity, and decreased aldosterone secretion

            Hydrochlorothiazide is a thiazide diuretic that inhibits Na reabsorption in distal renal tubules resulting in increased excretion of Na+ and water, also K+ and H+ ions

            Administration

            Oral Administration

            Dosage adjustment may be required in geriatrics

            To minimize dose-independent side effects, it is usually appropriate to begin combination therapy only after a patient has failed to achieve the desired effect with monotherapy

            Minimize hydrochlorothiazide dose to minimize electrolyte disturbances

            Less effective in African-Americans

            Food decreases absorption; manufacturer recommends administration 1 hr before meal
