Mechanism and action
Ovestin: Estriol in Ovestin binds estrogen receptors with shorter receptor occupancy than estradiol, producing a 'weak' estrogenic effect. Stendra: 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 Ovestin is preferred
Ovestin vaginal preparations are approved for treatment and prevention of urogenital atrophy and recurrent urinary tract infections in postmenopausal women, and in some markets for vaginal preparation before pelvic surgery.
When Stendra is preferred
Stendra is approved for erectile dysfunction in adult men.
