The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.
When two drugs affect each other, it is a drug–drug interaction (DDI). The risk of a DDI increases with the number of drugs used. [1] A large share of elderly people regularly use five or more medications or supplements, with a significant risk of side-effects from drug–drug interactions. [2] Drug interactions can be of three kinds:
If the combination of two drugs in combination therapy has an effect lower than the sum of the effects of the two drugs acting independently, also known as antagonistic effect, the drugs will seldom be prescribed together in the same therapy. Drug or chemical combinations with additive effects can cause adverse effects.
There are many writings that portray drug culture. Hunter S. Thompson's 1971 novel Fear and Loathing in Las Vegas employs multiple drug use as a major theme and provides an example of the drug culture of the 1960s.

Although both terms relate to drug response based on genetic influences, there are differences between the two. Pharmacogenetics is limited to monogenic phenotypes (i.e., single gene-drug interactions). Pharmacogenomics refers to polygenic drug response phenotypes and encompasses transcriptomics, proteomics, and metabolomics.
The Louisiana House approved a bill Tuesday that would add two medications commonly used to induce abortions to the state’s list of controlled dangerous substances, making possession of the ...
