Additive effect can be used to detect synergy as it can be considered as the baseline effect in methods determining whether drugs have synergistic effect. Synergistic effect is similar to additive effect, having a combination effect greater than additive effect. It can produce an effect of 2+2 > 4 when two drugs are used together.
Antibiotic synergy is desirable in a clinic sense for several reasons. At the patient level, the boosted antimicrobial potency provided by synergy allows the body to more rapidly clear infections, resulting in shorter courses of antibiotic therapy. [3] Shorter courses of therapy in turn reduce the effects of dose-related toxicity, if applicable ...
Synergy is an interaction or cooperation giving rise to a whole that is greater than the simple sum of its parts (i.e., a non-linear addition of force, energy, or effect). [1]
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:
A codrug consists of two drug moieties, generally "active against the same disease", that are joined through one or more covalent chemical bonds to create a single new chemical entity; [1] they can also be described as a mutual prodrug, recognising that a catabolic biosynthetic step is most often required to liberate the two drugs. [2]
Combined drug intoxication use often carries with it more risk than use of a single drug, due to an increase in side effects, and drug synergy. The potentiating effect of one drug on another is sometimes considerable and here the licit drugs and medicines – such as alcohol, nicotine and antidepressants – have to be considered in conjunction ...
Broadly, a synergist is an entity that displays synergy with respect to another entity. More specifically, a synergist may be: a synergist muscle; a substance that enhances the effect of another substance, such as a drug (see Synergy § Biological sciences) something relating to the theological position of synergism
Lethal synergism between influenza virus and pneumococcus, causes excess mortality from secondary bacterial pneumonia during influenza epidemics. Influenza virus alters the lungs in ways that increase the adherence, invasion and induction of disease by pneumococcus, alters the immune response with weakened ability to clear pneumococcus or ...
