How Viagra works?
Viagra is a well-known drug that helps men who have trouble getting or keeping an erection. ED is a common condition that affects many men at some point in their lives and can have a significant impact on their quality of life. In this article, we will explore everything you need to know about Viagra, including how it works, its benefits and side effects, and how to use it safely and effectively.
How Does Viagra Work?
Viagra works by increasing blood flow to the penis, which helps men with ED to achieve and maintain an erection. The active ingredient in Viagra is sildenafil, which belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. When a man is sexually stimulated, the brain releases a chemical called nitric oxide, which triggers the production of another chemical called cyclic guanosine monophosphate (cGMP). cGMP relaxes the smooth muscles in the penis, which allows for increased blood flow and an erection.
However, PDE5 can break down cGMP, which can reduce blood flow to the penis and cause ED. Viagra works by blocking the action of PDE5, which allows cGMP to remain in the penis for longer, increasing blood flow and helping to maintain an erection.
Benefits of Viagra
Viagra has been shown to be an effective treatment for ED in many men. The medication is fast-acting, with most men noticing an improvement in their symptoms within 30 minutes to an hour after taking it. Additionally, Viagra can help men with ED to achieve and maintain an erection for a longer period of time, allowing for a more satisfying sexual experience.
Viagra is also convenient and easy to use, with a simple dosing schedule. The medication is taken orally, usually about 30 minutes before sexual activity, and can be taken with or without food. Some men may find that Viagra is more effective when taken on an empty stomach, while others may prefer to take it with a meal.
Side Effects of Viagra
Like all medications, Viagra can cause side effects in some men. The most common side effects of Viagra include headache, facial flushing, and indigestion. These side effects are usually mild and go away on their own within a few hours.
Other, less common side effects of Viagra include changes in vision or hearing, dizziness, and an erection that lasts for longer than four hours (known as priapism). If you experience an erection that lasts for longer than four hours, you should seek medical attention immediately, as this can be a serious condition.
How to Use Viagra Safely and Effectively
It is important to use Viagra only as directed by your healthcare provider. You should not take more than one dose of Viagra in a 24-hour period, and you should not take the medication more often than once a day.
Viagra is not recommended for use in men who take certain medications, such as nitrates, as this can lead to a dangerous drop in blood pressure. If you are taking any medications, including over-the-counter medications and supplements, it is important to discuss these with your healthcare provider before starting treatment with Viagra.
In addition, if you have a medical condition such as heart disease, high or low blood pressure, liver or kidney problems, or a history of stroke or heart attack, you should talk to your healthcare provider before taking Viagra.
