Metabolic Clearance Rate of Oxytocin in Human Subjects

[Metabolic clearance rate of oxytocin in human subjects].

Oxytocin metabolism seems to occur mainly in the kidney and the liver. Placental cystine amino peptidase (CAP), which inactivates oxytocin by cleavage of the bond between the N-terminal cystine residue and adjacent tyrosine, rises progressively with advancing gestation. The role of CAP in oxytocin metabolism is not clear. To clarify this issue, the authors measure oxytocin metabolic clearance r...

Metabolic clearance rate and blood production rate of testosterone and dihydrotestosterone in normal subjects, during pregnancy, and in hyperthyroidism.

The metabolic clearance rate (MCR) and blood production rate (BP) of testosterone (T) and dihydrotestosterone (DHT), the conversion of plasma testosterone to plasma dihydrotestosterone, and the renal clearance of androstenedione, testosterone, and dihydrotestosterone have been studied in man. In eight normal men, the MCR(T) (516+/-108 [SD] liters/m(2)/day) was significantly greater than the MCR...

Effect of pregnancy on the metabolic clearance rate and the volume of distribution of oxytocin in the baboon.

Pharmacokinetic parameters of oxytocin (OT) metabolism were determined during the last third of pregnancy and again 4-8 wk after delivery in the baboon. Animals were placed on a tether system with venous and arterial access and a continuous monitoring of uterine contractions during gestation. Two methods of determining OT pharmacokinetics were utilized (bolus injection vs. continuous infusion)....

The metabolic clearance rate of aldosterone in pregnant and nonpregnant subjects estimated by both single-injection and constant-infusion methods.
