The Anatomical Therapeutic Chemical (ATC) Classification System is a drug classification system that classifies the active ingredients of drugs according to the organ or system on which they act and their therapeutic, pharmacological and chemical properties. Its purpose is an aid to monitor drug use and for research to improve quality ...
A drug class is a group of medications and other compounds that have similar chemical structures, the same mechanism of action (i.e. binding to the same biological target), similar modes of action, and/or are used to treat the similar diseases. [1][2] The Food and Drug Administration (FDA) has worked on classifying and licensing new medications ...
MDMA is a moderately teratogenic drug (i.e., it is toxic to the fetus). [102][103] In utero exposure to MDMA is associated with a neuro - and cardiotoxicity [103] and impaired motor functioning. Motor delays may be temporary during infancy or long-term.
This classification system reflects the stage of the child's disease, establishes mutually exclusive classification categories, and balances simplicity and medical accuracy in the classification process. This document also describes revised pediatric definitions for two acquired immunodeficiency syndrome-defining conditions.
There are different classes of hypoglycemic drugs, and selection of the appropriate agent depends on the nature of diabetes, age, and situation of the person, as well as other patient factors. Diabetes mellitus type 1 is a disease caused by the lack of insulin. Thus, Insulin is the main treatment agent for type 1 and is typically administered ...
Gallamine and other chemical classes Gallamine is a trisquaternary ether with three ethonium heads attached to a phenyl ring through an ether linkage. Many other different structures have been used for their muscle relaxant effect such as alcuronium (alloferin), anatruxonium , diadonium , fazadinium (AH8165) and tropeinium .
The initial classification system had 4 classes, although their definitions different from the modern classification. Those proposed in 1970 were: [2] Drugs with a direct membrane action: the prototype was quinidine, and lignocaine was a key example. Differing from other authors, Vaughan-Williams describe the main action as a slowing of the ...
A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being. [3] Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. [4] Pharmaceutical drugs may be used for a limited ...
