That phenomenon is called drug interaction.
A chemical antagonist is any substance which neutralises, masks or inhibits the action of another chemical. A good example would be EDTA which effectively "locks up" or "sequesters" metal ions in solution to render them inactive. The term is most often found in Pharmacology where one drug may inhibit the action of another.

Not relating to the action of a drug when given to a healthy person.In other words the action is not dose-dependent.So no matter how much of the drug is given to the patient, the symptom will be observed.E.g. 'On-off' effect seen in levodopa users after 2-5 years of use.
Pharmacodynamics is the study of the biochemical and physiological effects of drugs on the body or on microorganisms or parasites within or on the body and the mechanisms of drug action and the relationship between drug concentration and effect.
The greatest challenge to forensic science isn't any one drug, but a combination of drugs and chemicals and their complex reactions. The longer the drug remains in the body, the more it is metabolized into another substance.
The Multiplier Effect
Pharmacological action refers to the specific biochemical interactions between a drug and its target in the body, while pharmacological effect is the overall outcome or response produced by these actions, including the therapeutic and side effects of the drug. In other words, the action is the mechanism of how the drug works, while the effect is the result of this action on the body.
Pharmaceutical phase of drug action is the first of the three phases to drug action. It includes the disintegration of the dosage form as well as the dissolution of the drug
lysosomes play a role in drug action...
a drug that inhibits the action of the sympathetic sysytem
The Multiplier Effect
site of action is the location (site) where the drug do there action ........ while onset of action is the starting of effects produced due to drug............... both are clearly different..........
Local Action
In literature, an antagonist is a character, group of characters, or an institution which opposes the protagonist, the main character(s). The antagonist struggles against, opposes, or competes with the protagonist. In biochemistry, the antagonist is a substance that interferes with or inhibits the physiological action of another. In anatomy, the antagonist is a muscle whose action counteracts that of another specified muscle. In pharmacology, the antagonist is a drug that counteracts the effects of another drug.
