Potentiator
Potentiator
Potentiator (pronunciation: poh-ten-shee-ay-tor) is a term used in the field of Pharmacology to describe a substance that enhances the effect of another substance.
Etymology
The term 'Potentiator' is derived from the Latin word 'potentia', meaning 'power', and the suffix '-tor', which is used to denote an agent.
Definition
A Potentiator is a type of drug interaction where one drug enhances the effect of another. This can occur when the potentiator drug increases the concentration of the other drug in the body, or when it enhances the body's response to the other drug. Potentiators can be used to increase the efficacy of a drug, or to reduce the required dosage, potentially reducing side effects.
