Despite its widespread use, Viagra is not suitable for everyone.

It is contraindicated in individuals using nitrate drugs for chest pain or heart problems, as the combination can cause a dangerous drop in blood pressure.
Its development and subsequent popularity have not only provided therapeutic benefits to millions of men worldwide but have also paved the way for greater openness in discussing and addressing sexual health issues. In conclusion, Viagra remains a pivotal treatment for erectile dysfunction with a well-established efficacy and safety profile. Viagra, chemically known as sildenafil citrate, was initially developed for the treatment of hypertension and angina pectoris, a type of chest pain associated with coronary heart disease.
This serendipitous discovery led to its approval by the U.S. However, during clinical trials in the early 1990s, an unexpected property of Viagra emerged—it significantly improved erectile function. Food and Drug Administration (FDA) in 1998 as the first oral treatment for erectile dysfunction (ED). By inhibiting PDE5, Viagra effectively increases the levels of cGMP, enhancing and prolonging erections in men suffering from ED. PDE5, however, breaks down cGMP, thus inhibiting the ability to achieve or maintain an erection.
The drug is effective only with sexual stimulation, as it relies on the initial release of nitric oxide by the body. Additionally, research continues into its possible therapeutic roles in other conditions, demonstrating the versatility and potential of this molecule beyond its initial scope. Viagra has also been studied for other potential uses, such as the treatment of pulmonary arterial hypertension under the name Revatio. Individuals with cardiovascular conditions, particularly those taking nitrate drugs for chest pain, are advised against using Viagra due to the risk of severe blood pressure drops.
In PAH, Viagra helps relax blood vessels in the lungs, improving blood flow and reducing the heart’s workload. For instance, it has shown potential benefits in treating pulmonary arterial hypertension (PAH), a rare but serious heart condition. Beyond its primary use in treating ED, Viagra has also been explored for other medical conditions. However, it is important to note that Viagra does not lead to an erection without sexual stimulation; it merely facilitates the process when the conditions are right.
Viagra is administered orally, typically in dosages ranging from 25 mg to 100 mg. It is advised to be taken approximately one hour before sexual activity, and its effects can last for up to four hours.
