An experimental study was done to examine a potential role of phosphodiesterase (PDE) inhibitors in the treatment of diabetic erectile dysfunction, Relaxant effect of specific PDE inhibitors were measured in strips of corpus cavernosum smooth muscle taken from control and diabetic groups. Diabetes mellitus was induced in New Zealand white rabbits using alloxan, Penises excised from diabetic rabbits 8 weeks after the induction of diabetes mellitus, In the organ bath strips from control and diabetic rabbit corpus cavernosum were precontracted and increasing doses of several PDE inhibitors were added. In the precontracted rabbit cavernous tissue, sulmazole and zaprinast specific PDE V inhibitors were equally potent and efficacious in vitro but amrinone, a specific PDE III inhibitor, exhibits low relaxant effects. All PDE inhibitors tested showed a similar relaxation effect on corpus cavernosum smooth muscle from control and 8-week diabetic rabbits, The present study provides the possibility of using selective PDE III and V inhibitors in the treatment of diabetic impotence.
