What are the 5 drug classifications?

The five classes of drugs are narcotics, depressants, stimulants, hallucinogens, and anabolic steroids.

What are the four main drug actions?

Absorption: Describes how the drug moves from the site of administration to the site of action. Distribution: Describes the journey of the drug through the bloodstream to various tissues of the body. Metabolism: Describes the process that breaks down the drug. Excretion: Describes the removal of the drug from the body.

What are the mechanisms of drug action?

A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor. Receptor sites have specific affinities for drugs based on the chemical structure of the drug, as well as the specific action that occurs there.

What are the basic principle of drug actions?

Principles of drug action encompass three major topic areas: drug administration, pharmacokinetics, and pharmacodynamics.

What are the 2 classification of drugs?

Drugs can be categorised by the way in which they affect our bodies: depressants – slow down the function of the central nervous system. hallucinogens – affect your senses and change the way you see, hear, taste, smell or feel things. stimulants – speed up the function of the central nervous system.

What are the classification of drugs and their effects?

Drug Classifications By Effect

In general, addictive drugs may be classified as Stimulants, Depressants, Hallucinogens, or Opioids. These four drug classifications separate substances by how they interact with the brain and alter a person's mindset and behavior.

What is meant by drug action?

The function of a drug in various body systems. Its action may be (1) astringent when the drug causes the cell or tissue to contract, (2) corrosive when the drug is strong enough to destroy cells, or (3) irritating when too much of the drug combines with cells and impairs them. ...

What is pharmacokinetics and pharmacodynamics?

The difference between pharmacokinetics (PK) and pharmacodynamics (PD) can be summed up pretty simply. Pharmacokinetics is the study of what the body does to the drug, and Pharmacodynamics is the study of what the drug does to the body.

What is drug distribution?

Drug distribution is the disbursement of an unmetabolized drug as it moves through the body's blood and tissues. The efficacy or toxicity of a drug depends on the distribution in specific tissues and in part explains the lack of correlation between plasma levels and the effects that are seen.
