Introduction to Prasterone
Prasterone, also known as dehydroepiandrosterone (DHEA), is a steroid hormone that has been studied and approved for the treatment of moderate to severe dyspareunia and vaginal dryness associated with menopause. Here, we will delve into the clinical trials, market analysis, and future projections for this drug.
Clinical Trials and Efficacy
Several clinical trials have evaluated the efficacy and safety of prasterone in postmenopausal women.
Primary Efficacy Trials
Two primary placebo-controlled efficacy trials involving 716 women with moderate to severe dyspareunia and vaginal dryness were conducted. These trials showed that prasterone 6.5 mg (0.5%) vaginal inserts significantly improved dyspareunia symptoms compared to placebo. The severity of dyspareunia decreased by 0.36 to 0.40 points on a scale of 0 to 3, where 3 is the worst pain[4][5].
Vaginal Health Parameters
Prasterone also improved objective vaginal atrophy parameters, including vaginal pH, and the percentage of superficial and parabasal cells. These improvements were statistically significant and maintained over 12 weeks and even up to 52 weeks in some studies[1][5].
Comparison with Other Treatments
Prasterone was found to be at least as effective as conjugated equine estrogens (CEE) and estradiol in treating dyspareunia and vaginal dryness, without the systemic adverse effects associated with estrogen therapies[1].
Safety and Tolerability
Prasterone has been shown to be generally safe and well-tolerated. Common adverse reactions include application site discharge, reported in 8.3% of patients. There were no significant increases in serum steroid concentrations or risks of endometrial hyperplasia or cancer. However, prasterone is contraindicated in women with undiagnosed, persistent, or recurring genital bleeding and in those with a known or suspected history of breast cancer, although it has not been specifically studied in this population[1][4][5].

Challenges and Limitations
Clinical Trial Limitations
The clinical trials for prasterone had limitations, including a lack of diversity among participants (92% were Caucasian) and exclusion criteria that limited the applicability of the findings to the general population. Future studies should aim to include a more diverse population to better understand the drug's efficacy and safety across different demographics[1].
Regulatory Considerations
Prasterone is listed on Schedule IV of the Controlled Drugs and Substances Act due to its classification as an anabolic steroid and its derivatives. This regulatory status may impact its prescription and use[5].
