  • Why is sildenafil 20mg so much more affordable?
    • Sildenafil 20mg is the generic equivalent to a brand name medication called Revatio® 20mg. Revatio® 20mg was able to obtain a patent for Sildenafil 20mg where Viagra® was able to obtain a patent for 25mg, 50mg, and 100mg.
    • These brand name medications of Viagra® and Revatio® have the exact same active ingredients but differ in milligram strength. Revatio® 20mg lost its brand name patent and generics have been available for years. This is why Sildenafil 20mg is significantly more affordable than brand name Viagra® even though they are the same active ingredient. This holds true for the generic sildenafil with the strengths Viagra® came in, as the manufacturers still charge more for the same ingredient despite not having the brand name.
