| tocolytic agent | A medication that can inhibit labour, slow down or halt the contractions of the uterus. Tocolytic agents are widely used today to treat premature labour and permit pregnancy to procede and so permit the foetus to gain in size and maturity before being born. (12 Dec 1998) |
| tocolytic agents | Drugs that prevent preterm labour and immature birth by suppressing uterine contractions. Agents used to delay premature uterine activity include magnesium sulfate, beta-mimetics, oxytocin antagonists, calcium channel inhibitors, and adrenergic beta-receptor agonists.

Name given to vitamin E by its discoverer, but now a generic term for vitamin E and compounds chemically related to it, with or without biological activity; similar in chemical structure and properties to vitamins K and coenzyme Q. 2.
