Tadaflo 5 mg is a medication used to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH) in men. It contains the active ingredient tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil works by relaxing the blood vessels in the penis, increasing blood flow, and helping to achieve and maintain an erection when sexually aroused. Additionally, it relaxes the muscles in the prostate and bladder, which can help alleviate symptoms of BPH such as difficulty in urination.
