Introduced in 2012, Stendra was the last of the brand-name erectile dysfunction drugs to debut on the U.S. market. Because it still has valid U.S. patents in force, it probably won’t go generic until 2025.
Stendra is the new kid on the block among the brand-name erectile dysfunction drugs available in the United States. Introduced in 2012, it is unlikely to face generic competition until 2025. This makes it the only brand-name ED medication without generic competition.
Stendra’s active ingredient is avanafil, a chemical compound that belongs to the family of ED medications known as PDE5 inhibitors. They are so-called because they temporarily sideline an enzyme known as phosphodiesterase-5, which can interfere with optimal blood flow to the penis.
How It Compares to Viagra, Levitra
Dispensed in tablets of 50, 100, and 200 mg, Stendra takes effect quickly — as little as 15 minutes — and lasts for up to six hours. This makes it faster acting than either Viagra or Levitra and slightly longer lasting than either of those drugs.
Stendra’s recommended starting dose is 100 mg, although many users prefer to buy 200 mg tablets, which are the same price as their 100 mg counterparts. The higher-strength tablets can then be split to yield two 100 mg doses for the price of one.
No Generic Version Available
While Stendra is competitive in price with both Levitra and Viagra, the ED drugs to which it is most comparable, both Levitra and Viagra have generic alternatives that are available for considerably less than the brand-name medications.
When a new brand-name medication is approved, it usually enjoys a lengthy period of exclusivity. In the United States, its patents offer a preliminary measure of protection, although other drug companies can — and sometimes do — challenge the validity of those patents.
Two Valid US Patents in Effect
According to the Food and Drug Administration’s Orange Book, Stendra has two valid U.S. patents that are in effect. The latest-expiring of the two is valid until April 2025. Absent a successful challenge to one of those patents, it’s unlikely that a generic alternative to Stendra will be marketed before April 2025.
As of February 2020, the average price for a 100 mg tablet of Stendra was $69.30, according to Secure Medical’s monthly review of prescription drug prices. That’s $10.57 cheaper than the $79.87 average price of 100 mg Viagra in February, but it is $12.78 more expensive than the $56.52 price for a 20 mg tablet of Levitra, which is equivalent in strength to 100 mg Viagra and Stendra.
