Vidalista 10 mg, containing Tadalafil, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This inhibition results in the relaxation of blood vessels in the penis, enhancing blood flow during sexual stimulation. Consequently, it helps achieve and maintain an erection. Tadalafil also has a longer half-life compared to other similar medications, allowing for prolonged effectiveness. It’s important to note that sexual arousal is necessary for Vidalista to work effectively. The medication is primarily used to treat erectile dysfunction and, in some cases, benign prostatic hyperplasia (BPH).
