Viagra, known generically as sildenafil, is a medication primarily used to treat erectile dysfunction (ED) in men. Approved by the FDA in 1998, it revolutionized the way ED was managed, offering a solution to millions who experience difficulties in achieving or maintaining an erection. Understanding how Viagra works, its potential side effects, and considerations for use can help individuals make informed decisions regarding their sexual health.
How Viagra Works
Viagra functions by increasing blood flow to the penis, facilitating an erection when a man is sexually stimulated. The active ingredient, sildenafil, inhibits an enzyme called phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. By blocking PDE5, Viagra enhances the effects of nitric oxide, a natural chemical the body produces during sexual arousal. This process allows Viagra sicher kaufen for improved erectile function.
Dosage and Administration

Side Effects

In rare cases, it can cause more severe reactions, such as sudden vision loss, hearing loss, or priapism (a painful, prolonged erection). Men experiencing these severe side effects should seek immediate medical attention.
Considerations and Contraindications
