Mechanisms compared
Ovestin: Estriol in Ovestin binds estrogen receptors with shorter receptor occupancy than estradiol, producing a 'weak' estrogenic effect. Avanafil: Avanafil selectively inhibits phosphodiesterase type 5 (PDE5) in the corpus cavernosum, increasing cGMP and enhancing nitric-oxide-mediated vasodilation in response to sexual stimulation.
When the comparison makes sense
Comparing Ovestin with Avanafil makes sense when both are in the same clinical decision: the prescriber has weighed both for different but related conditions. If the question is between two options for the same need, the prescriber decides based on prior response, comorbidities and tolerance.
