Tadalafil is suitable for 5mg once a day and should be taken regularly over the long term

Tadalafil , due to its half-life of up to 17.5 hours, is currently the only type 5 phosphodiesterase inhibitor approved by the US Food and Drug Administration and the National Food and Drug Administration of China for the treatment of erectile dysfunction at a dose of 5mg once a day. Studies have shown that when 90% of type 5 phosphodiesterase is inhibited (IC-90), the penis can achieve a hard erection. Pharmacokinetic studies have shown that the IC90 plasma concentration of tadalafil is 55ng/mL; 5mg tadalafil can maintain a plasma concentration of 55ng/mL for 24 hours. Use 5mg of tadalafil daily and reach steady blood drug concentration after 5 days.
The pharmacokinetic characteristics of tadalafil make it particularly suitable for once daily, long-term, and regular use, allowing patients and their partners to freely determine the duration of medication and sexual activity, thereby completely disconnecting the association between drug use and sexual activity. Enhance the psychological benefits of patients, effectively improve vascular endothelial function (a common pathogenesis of erectile dysfunction and potential chronic diseases), benign prostatic hyperplasia, lower urinary tract symptoms, and protect cardiovascular health.
