An example demonstrating how drug combination with additive effect can cause adverse effects is the co-administration of ACEI and potassium-sparing diuretics. [3] Despite having different mechanisms of action, the drugs are able to reduce potassium excretion from the body.
Let and be doses of compounds 1 and 2 producing in combination an effect . We denote by D e 1 {\displaystyle D_{e1}} and D e 2 {\displaystyle D_{e2}} the doses of compounds 1 and 2 required to produce effect e {\displaystyle e} alone (assuming this conditions uniquely define them, i.e. that the individual dose-response functions are bijective).
A popular example of drug–food interaction is the effect of grapefruit on the metabolism of drugs. Interactions may occur by simultaneous targeting of receptors , directly or indirectly. For example, both Zolpidem and alcohol affect GABA A receptors , and their simultaneous consumption results in the overstimulation of the receptor, which can ...

The FDA already banned the use of red dye No. 3 in cosmetics and topical drugs in 1990 under the Delaney Clause after research found the additive to be carcinogenic at high doses for rats in lab ...
Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs). The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection).
January 1 not only ushered in 2025 but a slew of new laws. In 2024, states tackled issues ranging from abortion rights to gender-affirming care for minors, advancing legislation to take effect the ...
A classic example of this effect is the interaction between β-lactams, which damage the bacteria cell membrane, and aminoglycosides, which inhibit protein synthesis. [1] The damage dealt to the cell wall by β-lactams allows more aminoglycoside molecules to be taken up into the cell than would otherwise be possible, enhancing cell damage. [ 1 ]
