Effect and tolerability of combining lovastatin with nifedipine or lisinopril

Single cardiovascular risk factor intervention is probably not sufficient to prevent atherosclerosis progression. There is a lack of data on concomitant use of hypocholesterolemic agents and antihypertensive drugs with respect to possible interactions and adverse experiences. We studied 293 patients (below 65 years of age) under treatment with either lisinopril (n = 144) or nifedipine (n = 149) for mild to moderate hypertension for 10 weeks, and with serum cholesterol above 6.5 mmol/L, who were randomized to either lovastatin 20 mg every day or placebo in a double-blind, double-dummy design for 6 weeks. Lovastatin effectively lowered cholesterol by 16% and 15% in the lisinopril and nifedipine group respectively (P < .01 compared to placebo for both groups) without any negative impact on the antihypertensive efficacy of either lisinopril or nifedipine. The drugs in combination were well tolerated and did not affect the well-being of the patients, and did not cause any more adverse effects than the antihypertensive agents alone. Liver enzymes increased slightly during lovastatin therapy, while no case of myopathy was reported. Combined therapy with lovastatin and antihypertensive therapy can be safely undertaken.
