Purpose: Erectile dysfunction (ED) is a disorder found in males throughout the world, which
negatively affects relationships with partners with advancing age. Hence, in this study, we tested a
combined novel treatment of electro-acupuncture (EA) and sildenafil citrate against ED. In addition
to EA therapy, the sildenafil citrate, a phosphodiesterase 5 inhibitor, is a widely recognized drug
that has achieved considerable success in the treatment of ED. However, the combined effect of both the EA and sildenafil has not yet been investigated. Hence, we aimed to examine the effect of EA on the pharmacokinetics and pharmacodynamics of sildenafil in rat plasma.
Materials and Methods: The pharmacokinetic parameters were determined using ultra performance liquid chromatography (UPLC) after EA and sildenafil administration (10 mg/Kg). Following this, the pharmacodynamics was studied via blood flow pattern using developing doppler images of the lower body and penis.
Results: The pharmacokinetic studies demonstrated that sildenafil significantly increases by administration of low-frequency EA. Further, the pharmacodynamic studies using Doppler imaging revealed an elevated blood flow in rat penis compared with lower body during combined treatment of sildenafil and low-frequency EA.
Conclusions: In our study, the pharmacokinetic results demonstrated that low-frequency EA might elevate sildenafil (10 mg/kg, i.v.) concentration in rat plasma, while pharmacodynamic investigation revealed that combined treatment of sildenafil and low-frequency EA enhanced rats’ penile circulation. Therefore, we inferred that the combined therapy of sildenafil and low-frequency EA might be a good candidate for the treatment of ED.
