What is Teva sildenafil used for?
Teva's sildenafil is a generic version of Viagra and is prescribed to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, helping achieve and maintain an erection during sexual stimulation. Sildenafil is also used to treat pulmonary arterial hypertension (PAH) under the brand name Revatio, though Teva may market a generic version for this indication as well.
How does sildenafil work?
Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing muscles in the blood vessels, which allows blood to flow more easily to specific areas of the body. For erectile dysfunction, this means increased blood flow to the penis. For pulmonary arterial hypertension, it relaxes blood vessels in the lungs, reducing the pressure there [1].
When does Teva's sildenafil patent expire?
Drug patents are complex and can involve multiple patents covering different aspects of a drug. For sildenafil, the original patents have long expired, allowing for the production of generic versions like Teva's.
