Tadalafil Powder Usage and Synthesis.

Tadanafil is used to treat erectile dysfunction (ED) and pulmonary hypertension in men. Tadalafil and sildenafil belong to the same selective type 5 phosphodiesterase (PDE5), but its structure is different from that of the latter, and a high-fat diet does not interfere with its absorption. Under sexual stimulation, nitric oxide synthase (NOS) in penile nerve endings and vascular endothelial cells catalyzes substrate L-arginine to synthesize nitric oxide (NO). NO activates guanylate cyclase, which converts guanosine triphosphate into cyclic guanosine phosphate (cGMP), thereby activating cyclic guanosine phosphate dependent protein kinase, resulting in a decrease in the concentration of calcium ions in smooth muscle cells, resulting in relaxation of the smooth muscle of the corpus cavernosum and erection. Phosphodiesterase type 5 (PDE5) degrades cGMP into an inactive product, causing the penis to enter a weak state. By inhibiting PDE5 degradation, Tadanafil leads to cGMP accumulation, which relaxes the smooth muscle of the cavernous body of the penis and leads to penile erection. Since nitrates are NO donors, the combination with tadanafil can significantly increase the level of cGMP and lead to severe hypotension, therefore, clinical contraindication of the two.

Uses of Tadalafil.

Phosphodiesterase 5 inhibitors are used to treat erectile dysfunction in men. The second generation phosphodiesterase 5 inhibitors are used to treat bo dysfunction in men.

Drug interaction of Tadalafil.

Tadanafil affects PDES by inhibiting PDES. GMP degradation, so when used in combination with nitrocetacrets may cause an extreme drop in blood pressure and increase the risk of syncope. CY3PA4 inducer can reduce the abiotic availability of tadana. Combining with rifampicin, cimetidine, erythromycin, clarithromycin, itraconva, ketoconva, HVI protease inhibitor, etc., may increase the blood concentration of Tadana. Attention should be paid to adjust the dose. So far, there are no reports that the pharmacokinetic parameters of this product are affected by diet and alcohol.
