[Drug induced pulmonary hypertension]

Abstract

Primary pulmonary hypertension (PPH) is a rare, often fatal disease that tends to occur with particular frequency in woman. The factors leading to its development remain enigmatic. A variety of toxins and drugs have been implicated in the pathogenesis of pulmonary hypertension (PH). In the 1960s, the medical community was first alerted to the problem of an epidemic of PH in association with a particular anorexic agent, aminorex. Recent reports have indicated that anorexic drugs may have causative roles in PH. The International Primary Pulmonary Hypertension Study (IPPHS) showed a strong association between PPH and the use of appetite suppressants. But the mechanism by which these anorectic drugs cause PH is unknown.
