Abstract

Estrogen and progesterone replacement therapies are provided herein. Among others, the following formulations are provided herein: solubilized estradiol without progesterone; micronized progesterone without estradiol; micronized progesterone with partially solubilized progesterone; solubilized estradiol with micronized progesterone; solubilized estradiol with micronized progesterone in combination with partially solubilized progesterone; and solubilized estradiol with solubilized progesterone.

Claims

1. (canceled)

2. A pharmaceutical formulation comprising solubilized estradiol, suspended progesterone, and a medium chain solubilizing agent;

wherein each of the estradiol and the suspended progesterone are present in the solubilizing agent and the estradiol and the suspended progesterone are uniformly dispersed;

wherein at least about 90% of the estradiol is solubilized in the solubilizing agent; and

wherein the solubilizing agent comprises an effective amount of a C6-C12 oil.

3. The pharmaceutical formulation of claim 2, further comprising partially solubilized progesterone.

4. The pharmaceutical formulation of claim 2, wherein the formulation is contained within a gelatin capsule.

5. The pharmaceutical formulation of claim 2, wherein the medium chain solubilizing agent is selected from at least one of mono-, di-, and triglycerides and combinations thereof.

6. The pharmaceutical formulation of claim 2, wherein said estradiol has a dosage strength at least about 0.125 mg and wherein said progesterone has a dosage strength at least about 25 mg.

7. The pharmaceutical formulation of claim 2, wherein the ratio of progesterone to estradiol is at least 95:
