Pharmacology
Mechanism of Action
Mechanism not fully established regarding use in vulvar/vaginal atrophy
Inactive endogenous steroid that is converted into active androgens and/or estrogens
Absorption
Peak plasma concentration (at Day 7)
- Prasterone: 4.42 ng/mL
- Testosterone: 0.15 ng/mL
- Estradiol: 5.04 ng/mL
AUC (at Day 7)
- Prasterone: 56.17 ng·h/mL
- Testosterone: 2.79 ng·h/mL

Metabolism
Human steroidogenic enzymes (eg, hydroxysteroid dehydrogenases, 5-alpha-reductases and aromatases) transform prasterone into androgens and estrogens
