Everything below concerns pharmacology. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-07-19. Where a claim depends on a specific study, the study is described rather than over-claimed.
4-Chloromethcathinone (also known as 4-CMC and clephedrone) is a stimulant drug of the cathinone class that has been sold online as a designer drug. 4-CMC produces similar effects to mephedrone, and has been sold as an alternative in countries where mephedrone was scheduled. 4-CMC produces similar side effects to mephedrone, including: increased blood pressure, tachycardia, hyperthermia, and anxiety. Its chemical structure closely resembles para-chloromethamphetamine, raising concerns about its potential to readily induce cell death of serotonergic neurons. However, no neurotoxicity of this kind has been found to occur, but studies involving mice do indicate that it is neurotoxic through other mechanisms, similarly to other cathinones. 4-CMC is cytotoxic and induces oxidative stress, more so than 4-MMC. Moreover, β-keto substitution is thought to change cathinone structure activity relationships (SAR) and metabolism compared to amphetamines, leading to differences in pharmacology.

Absolute bioavailability compares the bioavailability of the active drug in systemic circulation following non-intravenous administration (i.e., after oral, buccal, ocular, nasal, rectal, transdermal, subcutaneous, or sublingual administration), with the bioavailability of the same drug following intravenous administration. It is the fraction of exposure to a drug (AUC) through non-intravenous administration compared with the corresponding intravenous administration of the same drug. The comparison must be dose normalized (e.g., account for different doses or varying weights of the subjects); consequently, the amount absorbed is corrected by dividing the corresponding dose administered. In pharmacology, in order to determine absolute bioavailability of a drug, a pharmacokinetic study must be done to obtain a plasma drug concentration vs time plot for the drug after both intravenous (iv) and extravascular (non-intravenous, i.e., oral) administration. The absolute bioavailability is the dose-corrected area under curve (AUC) non-intravenous divided by AUC intravenous. The formula for calculating the absolute bioavailability, F, of a drug administered orally (po) is given below (where D is dose administered).
The area under the effect curve (AUEC) is an integral of the effect of a drug over time, estimated as a previously-established function of concentration. It was proposed to be used instead of AUC in animal-to-human dose translation, as computer simulation shows that it could cope better with half-life and dosing schedule variations than AUC. This is an example of a PK/PD model, which combines pharmacokinetics and pharmacodynamics. Cmax (pharmacology) Cmean (pharmacology) "Area Under Curve" of the Receiver operating characteristic

In the field of pharmacokinetics, the area under the curve (AUC) is the definite integral of the concentration of a drug in blood plasma as a function of time (this can be done using liquid chromatography–mass spectrometry). In practice, the drug concentration is measured at certain discrete points in time and the trapezoidal rule is used to estimate AUC. In pharmacology, the area under the plot of plasma concentration of a drug versus time after dosage (called "area under the curve" or AUC) gives insight into the extent of exposure to a drug and its clearance rate from the body.
The American Society for Pharmacology and Experimental Therapeutics (ASPET) is a scientific society founded in late 1908 by John Jacob Abel of Johns Hopkins University (also the founder of the American Society for Biochemistry and Molecular Biology), with the aim of promoting the growth of pharmacological research. Many society members are researchers in basic and clinical pharmacology who help develop disease-fighting medications and therapeutics. ASPET is one of the constituent societies of the Federation of American Societies for Experimental Biology (FASEB). The society's headquarters are in Rockville, MD. The current president is Michael F. Jarvis.

The society publishes three research journals and a review journal: the Journal of Pharmacology and Experimental Therapeutics, Drug Metabolism and Disposition, Molecular Pharmacology, and Pharmacological Reviews Starting in 2012 these publications are only offered online. The society copublishes a wholly open access journal with the British Pharmacological Society and Wiley entitled Pharmacology Research & Perspectives. ASPET also publishes a quarterly newsletter, The Pharmacologist, and, from 2001 to 2011, Molecular Interventions magazine. The society gives out several awards:
