Aurogra 100 mg is marketed as containing sildenafil 100 mg, a PDE5 inhibitor used to treat erectile dysfunction (ED). It helps increase blood flow to the penis during sexual stimulation, making it easier to achieve and maintain an erection. For sildenafil, 50 mg is generally the recommended starting dose. Depending on effectiveness and tolerability, a healthcare professional may increase it to 100 mg. The maximum recommended dose is 100 mg once per day. It is usually taken about one hour before sexual activity, although it may be taken 30 minutes to 4 hours beforehand.
