1.1 Adverse Drug Reaction (ADR) ADRs may occur following a single dose or prolonged administration of a drug or may result from the combination of two or more drugs. (wikipedia.org)
As research better explains the biochemistry of drug use, fewer ADRs are Type B and more are Type A. Common mechanisms are: Abnormal pharmacokinetics due to: genetic factors comorbid disease states Synergistic effects between either: a drug and a disease two drugs Antagonism effects between either: a drug and a disease two drugs Various diseases, especially those that cause renal or hepatic insufficiency, may alter drug metabolism.

Covalent binding of reactive electrophilic intermediates to proteins is considered to play an important role in the processes leading to adverse drug reactions and idiosyncratic drug reactions. (tno.nl)

Moreover, penicillin allergy labels lead to the use of more expensive and less effective drugs and can result in adverse consequences, including longer length of hospital stay and increased risk for infection. (cdc.gov)

The main groups include sodium channel blockers, calcium current inhibitors, gamma-aminobutyric acid (GABA) enhancers, glutamate blockers, carbonic anhydrase inhibitors, hormones, and drugs with unknown mechanisms of action (see the image below). (medscape.com)
