Nifedipine, captopril, metoprolol and nifedipine with metoprolol in hypertensive crisis in non-intensive care setting.

In 102 cases of severe hypertension (DBP > or = 115 mm Hg), with or without acute complications, efficacy and safety of SL Nifedipine 10 mg (NIF), SL Captopril 25 mg (CAP), IV Metoprolol 15 mg (MET) and SL NIF + IV MET were studied in an inpatient trial. Maximum mean percent reduction in SBP was 13.3, 9.7, 15.7 and 19.9 and in DBP was 21.2, 13.9, 12.5 and 20.4 with NIF, CAP, MET and NIF + MET respectively. A safe DBP of < or = 110 mm Hg (Kaplan) was achieved in 90, 61, 72.2 and 95.2 percent of patients. A statistically significant fall in DBP was observed at 5 minutes with all regimens except CAP which was at 15 minutes. Mild side effects observed were palpitations and flushing (NIF n = 4), taste disturbances (CAP n = 3), heaviness of head (CAP n = 1) and giddiness (MET n = 2, NIF + MET n = 2). The trial data suggest that hypertensive crisis can be managed, without intensive care facility, with all four regimens; this implies significant cost containment.
