Since its accidental discovery and subsequent introduction to the market by Pfizer in 1998, Viagra has not only revolutionized the treatment of ED but also provided significant insights into cardiovascular and other physiological processes. Viagra, chemically known as sildenafil citrate, is a widely recognized medication primarily used for treating erectile dysfunction (ED) in men. Erectile dysfunction is a prevalent condition characterized by the inability to achieve or  [[https://www.facebook.com/goplay.se|doxycycline 100mg otc]] maintain an erection sufficient for satisfactory sexual performance.

The causes of ED are multifactorial and can include psychological issues, underlying health conditions such as diabetes and cardiovascular diseases, and lifestyle factors like smoking and obesity. However, it is important to note that Viagra does not increase sexual desire; it only helps to maintain an erection when sexual stimulation occurs. Viagra is administered orally, typically in dosages ranging from 25 mg to 100 mg. It is advised to take the medication about one hour before sexual activity, and its effects can last up to four hours.

However, during clinical trials, researchers discovered that it had a profound effect on erectile dysfunction (ED), which led to its repositioning as a treatment for this condition. Viagra, scientifically known as sildenafil citrate, was initially developed as a medication for treating high blood pressure and angina, a type of chest pain associated with heart disease. Since its approval by the FDA in 1998, Viagra has become one of the most well-known and frequently prescribed drugs for erectile dysfunction worldwide.

Furthermore, ongoing research is investigating the potential of Viagra in other areas, such as its effects on heart function, diabetes-related complications, and even certain types of cancer, demonstrating the broad therapeutic potential of this medication beyond its initial indication. It is contraindicated in individuals who take nitrates for heart disease, as mentioned, and those with certain health conditions such as severe liver impairment or recent history of stroke or heart attack.

Despite its benefits, Viagra is not suitable for everyone. However, Viagra is contraindicated in certain groups of patients, particularly those taking nitrates for chest pain, as the combination can lead to a dangerous drop in blood pressure.

These side effects are generally mild to moderate and transient. Despite its success, Viagra is not without side effects. The most common adverse effects include headaches, flushing, indigestion, nasal congestion, and dizziness. The prevalence of ED increases with age and can be influenced by a variety of factors including psychological issues, health conditions like diabetes and heart disease, and certain medications. Erectile dysfunction is a condition where a man is unable to achieve or maintain an erection adequate for satisfactory sexual performance.
