Editing Drug interaction (section)

==== Through enzymatic inhibition and induction ====
If a drug is metabolized by a CYP450 enzyme and drug B blocks the activity of these enzymes, it can lead to pharmacokinetic alterations. A. This alteration results in drug A remaining in the bloodstream for an extended duration, and eventually increase in concentration.{{Citation needed|date=November 2023}}

In some instances, the inhibition may reduce the therapeutic effect, if instead the metabolites of the drug is responsible for the effect.{{Citation needed|date=November 2023}}

Compounds that increase the efficiency of the enzymes, on the other hand, may have the opposite effect and increase the rate of metabolism.
