TX-004HR vaginal estradiol has negligible to very low systemic absorption of estradiol

Conclusions: Vaginal TX-004HR resulted in negligible to very low systemic absorption of estradiol. No statistical differences in estradiol PK parameters were observed on day 14 with 4 and 10 μg, and only minor increases were observed with 25 μg (within the normal postmenopausal range). This PK substudy, in conjunction with the primary efficacy results, demonstrated that TX-004HR provided local benefits of estradiol with limited systemic exposure.
