different factors those affect drug action - An Overview

When acid poisoning is handled with milk of magnesia, the alkaline action of milk of magnesia neutralizes the effects of acid poisoning.

In Figs 4 and ​and7,7, the dose was diminished abruptly. The ensuing reactions, nevertheless, usually do not rely on a unexpected modify in dose, but over the distinction between the actual dose as well as the dose to which the organism has made tolerance. Tolerance to a drug develops gradually and stays present quite a while.
