Healthy adults were given captopril (25 mg and 75 mg) po with or without dexamethasone (DXM) pretreatment (1 mg po 2 h before and simultaneously with the captopril). We determined the serum potassium and sodium concentrations, plasma prostaglandin E2 level, PRA, serum angiotensin converting enzyme (ACE) activity, and aldosterone level from 20 min before to 120 min after administration of captopril. DXM pretreatment stimulated the PRA response to captopril. This stimulation was suppressed by indomethacin. However, the administration of DXM did not induce a consistent rise in the prostaglandin E2 level. The administration of DXM induced a significant rise in the potassium concentration, but since simultaneous administration of indomethacin with captopril induced the suppression of PRA without affecting the potassium level, the PRA increase in response to captopril with DXM was not caused directly by the potassium increase. There were no significant differences in the PRA increase between 25 mg captopril and 75 mg captopril, or between DXM-25 mg captopril and DXM-75 mg captopril, though the inhibitions of ACE activity by captopril differed according to dose. The PRA increases, but not the captopril-induced inhibition of ACE activity, were significantly different between captopril alone and captopril with DXM pretreatment at either dose of captopril. Thus, the inhibition of ACE activity perhaps allows PRA to increase in response to captopril. These results suggest that the DXM stimulation of PRA may have been dependent on the inhibition of ACE activity by captopril.
