c.v) 30 min before sildenafil administration significantly reduced the CN activity. Also, the subeffective dose of CN inhibitor cyclosporine (5 mg/kg) 30 min before the administration of effective dose of sildenafil (40 mg/kg) reversed proconvulsant actions of sildenafil. This effect was iNOS-dependent because pretreatment of a low dose of aminoguanidine (20 mg/kg) 15 min before the administration of a low dose of cyclosporine (1 mg/kg) reversed the proconvulsant action of sildenafil (40 mg/kg). Finally, sildenafil indu
