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.
In the synergistic response, the applied antibiotics work together to produce an effect more potent than if each antibiotic were applied singly. [1] Compare to the additive effect , where the potency of an antibiotic combination is roughly equal to the combined potencies of each antibiotic singly, and antagonistic effect, where the potency of ...
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). [3] It may be difficult to distinguish between synergistic or additive interactions ...
Effects of this can be additive (outcome is greater than those of one individual drug), less than additive (therapeutic effects are less than those of one individual drug), or functional alterations (one drug changes how another is absorbed, distributed, and metabolized). [4]
Mechanisms that may be involved in the development of synergistic effects include: Effect on the same cellular system (e.g. two different antibiotics like a penicillin and an aminoglycoside; penicillins damage the cell wall of gram-positive bacteria and improve the penetration of aminoglycosides).

The birth rate in America has long been on a decline, with the fertility rate reaching historic lows in 2023. More women between ages 25 to 44 aren’t having children, for a number of reasons.
One toxic unit is equal to the EC50 for a given endpoint for a specific biological effect over a given amount of time. Toxic units allow for the comparison of the individual toxicities of a binary mixture to the combined toxicity. This allows researchers to categorize mixtures as additive, synergistic or antagonistic.
FORT PIERCE, Fla. — An "iron curtain" has descended here. Residents near a Cold War-era nuclear bomb shelter are wondering what the property's new owners are doing on the other side of the chain ...
