Viagra and Sildenafil, same medicine?
The switch to generic Sildenafil is an important development in the treatment of erection problems. It offers an effective solution at a more affordable price, which is key to making treatment accessible to more patients worldwide. With growing availability and reduced costs, it's no surprise that generic sildenafil has been preferred over the Viagra brand for many users.
What are the differences between Viagra and Sildenafil?
Viagra is a well-known drug for to treat erection problems and erectile dysfunction (ED). The active ingredient in Viagra is sildenafil citrate, also known as Sildenafil. This drug was developed by scientists in the United Kingdom and was marketed by the pharmaceutical company Pfizer. Approved by the FDA (Food and Drug Administration) in 1998, Viagra was the first oral medicine available to treat erection problems.
How do Viagra and Sildenafil work?
Viagra belongs to a class of medications known as PDE-5 inhibitors. Normally, PDE-5 breaks down a substance called cyclic guanosine monophosphate (cGMP), which helps relax the blood vessels in the penis. Viagra inhibits the action of PDE-5, leading to an increase in cGMP levels, relaxation of the blood vessels and promotion of blood flow to the penis. This mechanism helps to achieve and maintain an erection in response to sexual stimulation.
Why is the generic Sildenafil more popular these days?
The generic Sildenafil is now more popular than the Viagra brand for a number of reasons:
- Cost savings: Generic drugs are usually much cheaper than the brand-name variant. After the Viagra patent expired, other companies came out with their own versions of Sildenafil that are significantly cheaper. This makes it more accessible to a wider audience.
- Availability: With multiple manufacturers on the market, Sildenafil is more easily available than before. This has led to increased competition and lower prices.
- Trust in generic drugs: There is growing confidence among both doctors and patients in the effectiveness and safety of generic drugs. The MEB and EMA require that generic medicines have the same quality, strength, purity and stability as brand-name medicines.
- Regulations and Acceptance: Global health authorities, including the MEB and the European Medicines Agency (EMA), have approved generic versions of sildenafil.
