  • Abstract
  • Look Inside

A 23-year-old female with moderate primary pul-monary hypertension (PPH) was treated by chronic oral administration of long-acting prostaglandin-El (PGE1) and nifedipine. Cardiac catheterization re-vealed evidence that both drugs had beneficial effects on this case. Total pulmonary resistance (TSR) de-creased from 1089 to 955 dyne・sec・cm-5 by intrave-nous administration of PGE1at a rate of 0. 04 μg/kg /min and from 1089 to 710 dyne・sec・cm-5 by sub-lingual administration of nifedipine 10 mg respec-tively. After ten months of treatment with these two drugs, her pulmonary arterial pressure decreased from 85/40 (mean ; 58) mmHg to 55/36 (mean ; 45) mmHg, TSR decreased from 1089 to 829 dyne・sec・ cm-5 and Pa02 in room air increased from 74.5 to 94.9 mmHg. Chest X-P and ECG revealed the de-crease in the loading of the right ventricle. Thus, combined administration of PGE1 and nifedipine is expected to benefit PPH.
