The level of substance abuse increases with PMS, mostly with addictive substances such as nicotine, tobacco and cocaine. One theory behind this suggests this
Pharmacokinetics of progesterone biological half-life of progesterone in the circulation is very short; with intravenous injection, its half-life has ranged widely from 3 to 90 minutes in various studies. The metabolic clearance rate of progesterone ranges between 2,100 and 2,800 L/day, and is constant across the menstrual cycle. Progesterone is eliminated in bile and urine. Pharmacokinetics of progesterone The pharmacology of progesterone, a progestogen medication and naturally occurring steroid hormone, concerns its pharmacodynamics, pharmacokinetics, and various routes of administration. Progesterone is a naturally occurring and bioidentical progestogen, or an agonist of the progesterone receptor, the biological target of progestogens like endogenous progesterone. Progesterone
