First Clinical Trials of Viagra
The first clinical trials of Viagra, originally developed as a treatment for angina, began in the early 1990s. Pfizer registered subjects for trials in 1992, where they tested the drug’s effects on heart-related issues. During these trials, participants unexpectedly reported improvements in erectile function.
This surprising outcome redirected the focus of research. Subsequent studies concentrated on the drug’s efficacy in treating erectile dysfunction. The pivotal study conducted in 1996 enrolled over 800 men with varying degrees of erectile dysfunction. Participants received either Viagra or a placebo, with those on Viagra experiencing significant improvements.
Viagra, or sildenafil, enhances erectile function by increasing blood flow to the penis. It achieves this through a specific mechanism of action involving phosphodiesterase type 5 (PDE5) inhibition.
The Mechanism of Action
Upon sexual stimulation, nitric oxide (NO) is released in the corpus cavernosum of the penis. This process triggers the production of cyclic guanosine monophosphate (cGMP), which relaxes smooth muscle and dilates blood vessels, allowing for increased blood flow. Viagra works by:
- Inhibiting PDE5, an enzyme that breaks down cGMP.
- Boosting levels of cGMP, thus prolonging its effects and enhancing blood flow.
- Promoting prolonged smooth muscle relaxation, leading to an erection.
Viagra does not induce an erection without sexual stimulation. Its effects typically last for 4 to 6 hours, making it important to plan accordingly. Recommended doses range from 25 to 100 mg, depending on individual tolerability and effectiveness. Factors such as age, overall health, and other medications can influence dosing.
Common side effects include headaches, flushing, and gastrointestinal discomfort. Consultation with a healthcare provider can help determine the suitability of Viagra for individual circumstances.
History of Sildenafil Citrate
Sildenafil Citrate, commonly known as Viagra, was developed by scientists at Pfizer in the late 1980s.
