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 ]
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.
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).
A marketing synergy refers to the use of information campaigns, studies, and scientific discovery or experimentation for research and development. This promotes the sale of products for varied use or off-market sales as well as development of marketing tools and in several cases exaggeration of effects.
Index inducer or just inducer predictably induce metabolism via a given pathway and are commonly used in prospective clinical drug-drug interaction studies. [2]Strong, moderate, and weak inducers are drugs that decreases the AUC of sensitive index substrates of a given metabolic pathway by ≥80%, ≥50% to <80%, and ≥20% to <50%, respectively.
Explore the concept of PK/PD models, which integrate pharmacokinetics and pharmacodynamics to optimize drug dosing and efficacy.
[25] [26] Early epidemiological studies, for example, evaluated the ways in which social and health conditions co-occurred. Tsai argued that instead, there is a deeper need to interrogate how conditions syngistically interact to cause more adverse health conditions that the conditions would produce on their own.
[1] [2] Clinical pharmacology is inherently a translational discipline underpinned by the basic science of pharmacology, engaged in the experimental and observational study of the disposition and effects of drugs in humans, and committed to the translation of science into evidence-based therapeutics.
