Ultimately, a chemical called cyclic guanosine monophosphate (cGMP) causes the penis’s smooth muscle tissues to relax. This relaxation allows blood vessels to widen, and more blood flows into the penis. As a sufficient amount of blood accumulates, the penis enlarges and an erection occurs.
In 2023 Cialis Together (10mg tadalafil) was licensed as a 'P' medicine and is available over the counter in pharmacies without a prescription. The patent for Cialis expired in the UK on 14 November 2017, allowing other drug manufacturers to legally make and sell generic versions (marketed as tadalafil). Generic medicines are medically identical to branded originals and are usually much lower cost. This article is for informational purposes only and does not constitute medical advice.

Timing of sexual activity was not restricted relative to when patients took Cialis. The efficacy and safety of tadalafil in the treatment of erectile dysfunction has been evaluated in 22 clinical trials of up to 24-weeks duration, involving over 4000 patients. CIALIS, when taken as needed up to once per day, was shown to be effective in improving erectile function in men with erectile dysfunction (ED). Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and corpus cavernosal smooth muscle. This response is mediated by the release of nitric oxide(NO) from nerve terminals and endothelial cells, which stimulates the synthesis of cGMP in smooth muscle cells. Cyclic GMP causes smooth muscle relaxation and increased blood flow into the corpus cavernosum.
