1. A pessary comprising about 25 μ
- g of 17β
-estradiol in a solubilizing agent comprising a medium chain oil, wherein after a single administration of the pessary to a patient provides, in a plasma sample from the patient;
1) a corrected geometric mean peak plasma concentration (Cmax) of 17β
-estradiol of about 19 pg*hr/ml to about 29 pg*hr/ml; and
2) a corrected geometric mean area under the curve (AUC)0-24 of 17β
-estradiol of about 75 pg*hr/ml to about 112 pg*hr/ml,wherein 17β
-estradiol is the only active hormone in the pessary.
