Tadapox Tablet is a combination medication that typically includes two active ingredients: Tadalafil and Dapoxetine. Tadalafil is primarily used to treat erectile dysfunction (ED) and works by increasing blood flow to the penis by inhibiting an enzyme called phosphodiesterase type 5 (PDE5). This leads to relaxation of the smooth muscles in blood vessels and improved blood flow, which helps achieve and maintain an erection. Tadapox Tablet, on the other hand, is used to treat premature ejaculation and works as a selective serotonin reuptake inhibitor (SSRI). Its primary effect is on the serotonin levels in the brain, which helps increase control over ejaculation, rather than directly influencing blood vessel function. The effect of Tadapox on blood vessels is primarily due to Tadalafil. By inhibiting PDE5, Tadapox Tablet promotes the relaxation of smooth muscle cells in the blood vessels, particularly those in the penis. This relaxation allows more blood to flow into the area, facilitating an erection in response to sexual stimulation. The blood vessel dilation effect of Tadapox Tablet can also sometimes affect other blood vessels in the body, though the primary and most significant effect is localized to the penile arteries. If you have specific concerns about how Tadapox or any medication might affect your cardiovascular health or blood vessels, it's best to discuss these with a healthcare provider who can provide personalized advice based on your health profile.
