Progesterone Micronized (Capsule)
Progesterone Micronized softgel capsule contains micronised progesterone, which is structurally and biologically identical to natural endogenous progesterone. Micronisation increases the bioavailability of progesterone. When micronised progesterone is administered after meals, maximal serum progesterone levels are significantly increased. Progesterone concentrations in the endometrial and breast tissue attain high level. Progesterone is approximately 96%-99% bound to serum proteins, primarily to serum albumin (50%-54%). Progesterone is metabolized to pregnanediols and pregnanolones in the liver. The glucuronide and sulfate conjugates of pregnanediol and pregnanolone are excreted in the bile and urine. Progesterone metabolites, which are excreted in bile, may undergo enterohepatic circulation.
