title: Half-life of 13,14-dihydro-15-keto prostaglandin f2 alpha in peripheral plasma of the pig.
abstract: The metabolite of prostaglandin F2 alpha (PGF2 alpha ) namely 13,14-dihydro-15-keto-prostaglandin F2 alpha (PGFM), was administered as an intravenous bolus injection into five adult pigs. Concentrations of PGFM in blood collected periodically after injection indicated a biexponential decline suggesting a rapid distribution to the extracellular fluid and a slower elimination by metabolism. A mean half-life value of 14.97 +/- 1.33 (SD) minutes was calculated for the second component of the decline in PGFM concentration.
