The therapeutic index is really a quantitative measurement from the relative basic safety of the drug. It is a comparison of the quantity of drug that produces a therapeutic impact compared to the amount of drug that provides a poisonous impact.
Also, drugs that share metabolic pathways can “compete” for the same binding sites on enzymes, So reducing the performance in their read more metabolism. By way of example, alcohol and some sedatives are metabolized because of the cytochrome P450 enzyme and just a minimal range of these enzymes exist to interrupt these drugs down.
