What is it when the combination of two drugs produces an effect greater than?

Two or more drugs that individually produce overtly similar effects will sometimes display greatly enhanced effects when given in combination. When the combined effect is greater than that predicted by their individual potencies, the combination is said to be synergistic.

Is an undesired and harmful effect a drug produced in a patient?

An adverse effect is an undesired harmful effect resulting from a medication or other intervention, such as surgery.

What is a biochemical drug?

Biochemical pharmacology is concerned with the effects of drugs on biochemical pathways underlying the pharmacokinetic and pharmacodynamic processes and the subsequent therapeutic and the toxicological processes.

Is the ability of one drug to enhance the effect of another quizlet?

Potentiation is an interaction in which the effect of only one of the two drugs is increased. In other words, a drug that has a mild effect enhances the effect of a second drug. An antagonistic drug interaction is the opposite of a synergistic effect.

When is the combined effect of two drugs?

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).

When a combination of two drugs has a greater effect than the sum of each individual drug?

In toxicology, synergism refers to the effect caused when exposure to two or more chemicals at one time results in health effects that are greater than the sum of the effects of the individual chemicals.

What is the difference between contraindications and side effects?

A side effect of some barrier methods may be an increase in urinary tract infections. Often it is the minor side effects that influence our choices in contraception. Contraindications are the physical conditions or circumstances that put some people at risk of danger from using a particular medication or device.

What is biochemical effect?

Biochemical responses of animals to environmental chemicals (biochemical biomarkers) can give measures of exposure, and sometimes also toxic effect. Biochemical biomarkers are likely to provide a measure of toxic effect, where they are based upon a molecular mechanism which underlies toxicity.

When two or more drugs work together to help enhance one another is called?

Synergetic is often used to describe the effect of drugs working together — where one drug increases the other’s effectiveness. Synergistic can also describe the cooperative efforts of several people working together — like a team of superheroes fighting crime.

When one drug decreases the effect of another drug it is said to be?

When the effect of one drug is impeded by another, the effects of these drugs are antagonistic.

When the combined effect of two drugs is less than the sum of their individual effects?

Antagonism: The joint effect of two or more drugs such that the combined effect is less than the sum of the effects produced by each agent separately. The agonist is the agent producing the effect that is diminished by the administration of the antagonist.

Which is the best definition of additive effects?

Additive Effects. Definition – What does Additive Effects mean? Additive effects are the resulting effect of two or more agents acting together. It is the sum of the effects of the individual agents. In relation to chemicals, additive effects are the sum of the effects of two chemicals when mixed together.

How are additive effects different from synergistic effects?

Additive effects are just one of three types of effects when chemicals are combined. Synergistic effects are when the combined effects are greater than those of each individual chemical. This can be dangerous, as each of the chemicals is able to work effectively on its own.

What happens when two drugs are mixed together?

Chemical incompatibilities between drugs change both the drug’s structure and its pharmacologic properties. Physical incompatibilities occur when two drugs are mixed together. The mixture results in the formation of a precipitate.
