Learn all you need about Sildenafil in this resourceful article.
What is Sildenafil?
Sildenafil, often marketed under the brand name Viagra, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. Originally developed by Pfizer, it works by increasing blood flow to certain areas of the body. Its primary action is to inhibit phosphodiesterase type 5 (PDE5), an enzyme that regulates blood flow in the penis.
Mechanism of Action
The science behind Sildenafil is fascinating. By inhibiting the PDE5 enzyme, Sildenafil promotes the relaxation of blood vessels and increases blood flow to the penis upon sexual stimulation, leading to an erection. This mechanism has made it an essential treatment option for ED. Moreover, the increased blood flow capability also aids in managing pulmonary arterial hypertension by relaxing blood vessels in the lungs.
Indications for Use
Sildenafil is primarily prescribed for:
– Erectile Dysfunction (ED): The most common use, helping men achieve and maintain an erection.
– Pulmonary Arterial Hypertension (PAH): Enhances exercise capacity and delays clinical worsening in both men and women.
How to Use Sildenafil
Sildenafil should be used as directed by a healthcare provider. Here are some general recommendations:
– Dosage for ED: Typically, a dose of 50 mg is recommended, taken as needed, about one hour before sexual activity. However, it can be taken anywhere from 30 minutes to four hours prior.
– Dosage for PAH: The usual dose is 20 mg, taken three times a day, spaced 4 to 6 hours apart.
Potential Side Effects
Like any medication, Sildenafil can cause side effects. While many users tolerate it well, some may experience:
– Common Side Effects: Headaches, flushing, upset stomach, abnormal vision (such as changes in color vision), nasal congestion.
– Serious Side Effects: Sudden vision loss, hearing loss, chest pain, shortness of breath, an erection lasting more than four hours.
If you experience any severe side effects, seek medical attention immediately.
