Viagra: A Comprehensive Guide to Understanding Its Use and Benefits
Viagra, known generically as sildenafil, is a popular medication primarily used to treat erectile dysfunction (ED). Since its introduction to the market in 1998, it has become one of the most famous treatments for this condition. Originally developed by Pfizer, the medication has helped millions of men worldwide regain their sexual confidence and improve their quality of life.
What is Viagra?
Viagra is a phosphodiesterase type 5 (PDE5) inhibitor. This class of drugs works by relaxing the blood vessels in the penis, allowing increased blood flow during sexual arousal. This enhanced blood flow can lead to an erection when combined with sexual stimulation.
How Does Viagra Work?
The mechanism of action of Viagra involves blocking the enzyme PDE5, which regulates blood flow in the penis. By inhibiting this enzyme, Viagra maintains higher levels of cyclic guanosine monophosphate (cGMP), which relaxes smooth muscle and promotes blood flow, facilitating an erection. It is crucial to note that Viagra only works in the presence of sexual stimulation.
Common Uses of Viagra
- Erectile Dysfunction (ED): The primary use of Viagra is to treat erectile dysfunction in men, helping them achieve and maintain an erection suitable for sexual intercourse.
- Pulmonary Arterial Hypertension (PAH): Besides ED, sildenafil (Viagra) is also prescribed under the brand name Revatio to manage PAH, a condition characterized by high blood pressure in the lungs.
Recommended Dosages and Administration
The recommended starting dose for Viagra in treating ED is 50 mg, taken as needed about one hour before sexual activity. Depending on efficacy and tolerability, the dose can be adjusted to a maximum of 100 mg or decreased to 25 mg. It’s essential not to exceed one dose per day.
