When two drugs affect each other, it is a drug–drug interaction (DDI). The risk of a DDI increases with the number of drugs used. [1] A large share of elderly people regularly use five or more medications or supplements, with a significant risk of side-effects from drug–drug interactions. [2] Drug interactions can be of three kinds ...
Version 3.0 also included drug transporter data, drug pathway data, drug pricing, patent and manufacturing data as well as data on >5000 experimental drugs. Version 4.0 was released in 2014. [ 4 ] This version included 1558 FDA-approved small molecule drugs, 155 biotech drugs and 4200 unique drug targets.
However, if a delay is observed between the drug administration and the drug effect, a temporal dissociation needs to be taken into account and more complex models exist: [6] [7] Direct vs Indirect link PK/PD models; Direct vs Indirect response PK/PD models [8] Time variant vs time invariant; Cell lifespan models; Complex response models
It was introduced by the scientists in pharmacology and biochemistry fields in the process of understanding the synergistic interaction between drugs and chemicals over the century. Additive effect often occurs when two similar drugs are taken together to achieve the same degree of therapeutic effect while reducing the specific adverse effect ...
IUPAC defines a pharmacophore to be "an ensemble of steric and electronic features that is necessary to ensure the optimal supramolecular interactions with a specific biological target and to trigger (or block) its biological response". [1] A pharmacophore model explains how structurally diverse ligands can bind to a common receptor site.
Topics of pharmacodynamics. 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).
In terms of drug-drug interactions, acetaminophen activates CAR, a nuclear receptor involved in the production of metabolic enzymes, which increases the metabolism of other drugs. This could either cause reactive intermediates/drug activity to persist for longer than necessary, or the drug will be cleared quicker than normal and prevent any ...
