-----------what is the meaning of synergy in medical terms.-------------?

Answer 1

Synergy when used as a medical term is defined as agents working together harmoniously as in coordination in the action of muscles, organs or substances

Answer 2

when the combination of two or more drugs have synergistic effects:

Drug synergism occurs when drugs can interact in ways that enhance or magnify one or more effects, or side effects, of those drugs. This is sometimes exploited in combination preparations, such as Codeine mixed with Paracetamol to enhance the action of codeine as a pain reliever. This is often seen with recreational drugs, where 5-HTP, a Serotonin precursor often used as an antidepressant, is often used prior to, during, and shortly after recreational use of MDMA as it increases the "high" and decreases the "comedown" stages of MDMA use. Other examples include the use of Cannabis with LSD, where the active chemicals in cannabis enhance the hallucinatory experience of LSD-use, reducing the risk of a "bad trip".
