🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAbsorption of this medicine is variable and depends on the formulation. Micronized progesterone is absorbed from the gastrointestinal tract, but food increases its bioavailability.
DistributionThis medicine is widely distributed in the body, including the uterus, breasts, and brain. It is highly protein-bound.
Protein BindingApproximately 96-99% bound to plasma proteins, mainly albumin and cortisol-binding globulin.
MetabolismThis medicine is metabolized in the liver primarily by cytochrome P450 enzymes, including CYP3A4, to various metabolites.
Half-LifeThe elimination half-life of this medicine is approximately 5-20 hours, depending on the route of administration.
ExcretionThis medicine and its metabolites are excreted mainly in the urine and feces.
BioavailabilityBioavailability of oral micronized progesterone is about 10% due to first-pass metabolism, but increases with food intake.
Onset of ActionThe onset of action varies depending on the indication; for luteal support, effects may be seen within days.
Peak Plasma TimePeak plasma concentrations are reached approximately 3-6 hours after oral administration.
Duration of ActionThe duration of action is typically 24-48 hours, depending on the dose and individual factors.

How It Works

This medicine works by binding to progesterone receptors in the nucleus of target cells, leading to changes in gene expression that promote endometrial maturation, inhibit uterine contractions, and support pregnancy. It also has anti-estrogenic effects on the endometrium.

Mechanism Steps

1
Binding to progesterone receptor: This medicine binds to progesterone receptors in the cytoplasm, causing a conformational change and translocation to the nucleus.
2
Gene transcription modulation: In the nucleus, the progesterone-receptor complex binds to DNA and modulates the transcription of specific genes.
3
Endometrial maturation: This leads to secretory transformation of the endometrium, preparing it for implantation and maintaining pregnancy.
4
Uterine relaxation: This medicine also reduces uterine contractility by affecting calcium channels and nitric oxide pathways.
