When two drugs are used together, their effects can be additive (the result is what you expect when you add together the effect of each drug taken independently),
synergistic
(combining the drugs leads to a larger effect than expected), or antagonistic (combining the drugs leads to a smaller effect than expected).
What is a synergistic effect of drugs?
Synergism, Synergy.
An interaction between two or more drugs that causes the total effect of the drugs to be greater than the sum of the individual effects of each drug
. A synergistic effect can be beneficial or harmful.
What two drugs cause synergistic effects?
Drug combinations that are likely to be synergistic are produced when drugs that act by different and distinct mechanisms of action are combined. Synergism or supraadditivity has been demonstrated when
local anesthetics are combined with opioids
or dissociative anesthetics and when NSAIDs are combined with opioids.
What is difference between additive and synergistic?
Additive effects are when the sum of the effect equals the two individual chemical effects combined. … Synergistic effects are when the
sum of the effect is more than the two individual chemical effects combined
.
What is synergy and antagonism?
Thus, synergism is used to
define a cumulative effect of multiple stressors that are greater than the additive sum of effects produced by the stressors acting in isolation
; this contrasts with the term “antagonism,” used to define a cumulative effect that is less than additive (Hay et al.
What is combined effect of drug?
When two drugs are used together, their effects can be additive (the result is what you expect when you add together the effect of each drug taken independently),
synergistic
(combining the drugs leads to a larger effect than expected), or antagonistic (combining the drugs leads to a smaller effect than expected).
What is an example of synergism?
Synergism is when you get a greater effect by combining two or more organisms or components together than you would get by adding the effects of each. … For example, a very famous synergy in nature example is that of

.
What is an example of potentiation?
When
the combined effect of two different drugs exceeds the expected additive effect of each of the drugs administered independently
