Tadalafil tablets 20 mg for erectile dysfunction (Cialis, Zalutia)
What are Tadalafil tablets 20 mg for erectile dysfunction (Cialis, Zalutia)?
Tadalafil belongs to the phosphodiesterase 5 inhibitor class of medications. It operates by enhancing blood circulation through the synthesis of cyclic guanosine monophosphate in the smooth muscle cells, thereby promoting increased blood flow. Widely recognized for its prolonged effects, Tadalafil boasts a half-life of 17.5 hours, a substantial extension compared to medications like sildenafil or vardenafil, which typically exhibit half-lives ranging from 4 to 5 hours. It is advisable to ingest the tablet at least 60 minutes prior to engaging in sexual activity.
Tadalafil tablets are notably effective for addressing erectile dysfunction. Activation of local penile nitric oxide release necessitates sexual stimulation, ensuring that an erection only transpires in the presence of sexual engagement. Rigorous clinical trials have conclusively demonstrated both the safety and efficacy of tadalafil in this regard.
