Barbiturate. Barbituric acid, the parent structure of all barbiturates. Barbiturates [a] are a class of depressant drugs that are chemically derived from barbituric acid. [2] They are effective when used medically as anxiolytics, hypnotics, and anticonvulsants, but have physical and psychological addiction potential as well as overdose ...
PD-1 and PD-L1 inhibitors act to inhibit the association of the programmed death-ligand 1 ( PD-L1) with its receptor, programmed cell death protein 1 (PD-1). The interaction of these cell surface proteins is involved in the suppression of the immune system and occurs following infection to limit the killing of bystander host cells and prevent ...
A myriad of drug-cellular interactions have been documented in the scientific literature and these vary with respect to the properties of target cells, drug dose and drug intermediates produced. Since artefactual mechanisms of action can be observed, [26] the following mechanisms which occur at clinically relevant drug concentrations are the ...
In some literature articles, the terms "mechanism of action" and "mode of action" are used interchangeably, typically referring to the way in which the drug interacts and produces a medical effect. However, in actuality, a mode of action describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living ...
The APA recommends antidepressant medication as an initial treatment choice in people with mild, moderate, or severe major depression, and that should be given to all people with severe depression unless ECT is planned. [30] Reviews of antidepressants generally find that they benefit adults with depression.

[4] Lithium is taken orally (by mouth). [4] Common side effects include increased urination, shakiness of the hands, and increased thirst. [4]
Antimetabolite. An antimetabolite is a chemical that inhibits the use of a metabolite, which is another chemical that is part of normal metabolism. [1] Such substances are often similar in structure to the metabolite that they interfere with the use of folic acid; thus, competitive inhibition can occur, and the presence of antimetabolites can ...
Risperidone. Risperidone, sold under the brand name Risperdal among others, is an atypical antipsychotic [2] used to treat schizophrenia and bipolar disorder. [2] It is taken either by mouth or by injection (subcutaneous or intramuscular). [2] The injectable versions are long-acting and last for 2–4 weeks.
