Viagra is produced by Pfizer, an American pharmaceutical company. It was registered, FDA-approved and launched in 1998. For almost two decades, only the patented branded version of Viagra was available to consumers globally. However, the patent protection expired, leading to numerous pharmaceutical companies worldwide gaining the right to produce Viagra generics based on Pfizer's ready-made medicinal formula. Today, the pharmaceutical market boasts analogues of Viagra from various manufacturers worldwide, including Indian companies. Studies conducted since the beginning of 2020 reveal that sildenafil, Viagra's main active ingredient, has immunomodulatory effects, making it a potential immunomodulatory medicine for COVID-19 treatment. Women's problems with arousal often lie more in the psychological area, requiring treatment by a gynecologist rather than Viagra. Buying Viagra generics is an excellent option as they are much cheaper than the original medicine.
