About
Viagra is a well-known prescription medication primarily used to treat erectile dysfunction (ED), a condition characterized by difficulty achieving or maintaining an erection sufficient for sexual activity. Its active ingredient, sildenafil citrate, belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Viagra works by increasing blood flow to the penis during sexual stimulation, which helps to facilitate and sustain an erection. It's typically taken orally in tablet form, usually about 30 minutes to an hour before anticipated sexual activity. Viagra has been shown to be effective for many men with ED and is generally safe when used as prescribed under the guidance of a healthcare professional.
