Rosuvastatin is an anti-hypercholesterolemic agent with good anti-inflammatory and antinociceptive responses. The objective of present study was to assess the pharmacological effects of interaction of rosuvastatin with coprescribed ACE inhibitors. For this purpose complexes of Rosuvastatin with enalapril, captopril and lisinopril were synthesized and characterized. Their spectroscopic analyses suggest that hydrogen bonded complexation occurs between rosuvastatin and selected ACE inhibitors at their carboxylic (COOH) and hydroxyl OH sites. The anti-nociceptive effect of complexes was assessed by formalin induced nociception in mice, antiinflammatory effect was evaluated by carrageenan induced paw edema in rats. Neuropharmacological behaviors were also studied on mice. All the complexes of Rosuvastatin showed analgesic behavior in rats and mice. Anti-inflammatory activity of complexes is found insignificant. Enalapril complex keeps sedative activity while complexes with captopril and lisinopril contain anti-depressant behaviors. Results suggest that the interaction of rosuvastatin with ACE inhibitors have consumed the active reacting sites of Rosuvastatin for which its anti-inflammatory, analgesic and gross locomotor behaviors have been affected. So it is suggested that Rosuvastatin should not be co-administered with any of these ACE inhibitors.
