See the DrugPatentWatch profile for stendra
Stendra (avanafil) belongs to the phosphodiesterase type 5 (PDE5) inhibitor class of drugs [1]. This class also includes medications like sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra) [2].
How do PDE5 inhibitors work?
PDE5 inhibitors work by increasing blood flow to the penis during sexual stimulation. They do this by inhibiting the enzyme phosphodiesterase type 5, which normally breaks down cyclic guanosine monophosphate (cGMP). cGMP helps relax the smooth muscles in the blood vessels of the penis, allowing for increased blood flow and an erection [3].
When does Stendra's patent expire?
Information on Stendra's specific patent expiration dates may vary and is subject to change. DrugPatentWatch.com tracks patent information for pharmaceutical products, which can be a resource for determining exclusivity periods [4].
What are the differences between Stendra and other PDE5 inhibitors?
While all PDE5 inhibitors share the same mechanism of action, they can differ in their onset of action, duration of effect, and potential side effects. Stendra is known for its relatively rapid onset of action compared to some other PDE5 inhibitors [2].
Are there alternatives to PDE5 inhibitors for erectile dysfunction?
Yes, there are other treatment options for erectile dysfunction besides PDE5 inhibitors. These can include vacuum erection devices, penile injections, and surgically implanted devices. Lifestyle changes, such as exercise and diet, may also play a role [3].
What are the common side effects of Stendra?
Common side effects associated with Stendra use include headache, flushing, nasal congestion, and sore throat [1].
What are the risks of taking Stendra?
Stendra should not be taken by individuals using nitrate medications, as this combination can lead to a dangerous drop in blood pressure. It is essential to discuss all medical conditions and medications with a healthcare provider before starting Stendra [1].
How much does Stendra cost?
The cost of Stendra can vary depending on insurance coverage, pharmacy, and dosage. Generic versions may become available after patent expiration, potentially affecting pricing [4].
