The active ingredient in Tadalista 40 is tadalafil, which works by promoting increased blood flow to the penis. This helps men achieve and maintain a firmer erection, which can lead to a more satisfying sexual experience for both partners. Tadalista is a long-lasting medication, so men can benefit from its effects for up to 36 hours. This can allow for greater spontaneity in intimate encounters, without the need for specific planning or timing. In a double-blind, placebo-controlled study, 483 patients with diabetes and erectile dysfunction were randomized to receive either placebo or 10 or 40 mg of tadalafil taken whenever they anticipated sexual activity. Tadalista 40 can also be used to treat symptoms of an enlarged prostate gland (BPH) by relaxing the muscles in the prostate and bladder. The way that Tadalista 40 works is the same as the way that Fildena 200 works. This can help improve urinary symptoms such as frequent need to urinate or difficulty peeing. It also reduces the risk of a stroke or heart attack by decreasing blood pressure in the arteries and veins. It is important to take tadalafil as directed by your doctor. The dosage is based on your medical history and your condition. Do not take more than the recommended dose, as doing so may increase your chances of side effects.
