Tadasoft 40 mg is effective in helping men achieve and maintain erections suitable for sexual activity. It works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. Sexual stimulation is still required for the medication to work; it does not cause spontaneous erections. The effects of Tadasoft 40 mg can last for up to 36 hours, allowing for greater spontaneity and flexibility in sexual activity without the need to time medication closely to intercourse. https://www.genericday.com/tadasoft-40-mg.html
