What is a treatment objective?

An objective is a specific skill that the patient must acquire to achieve a goal. The objective is what you really set out to accomplish in treatment. It is a concrete behavior that you can see, hear, smell, taste, or feel. An objective must be stated so clearly that almost anyone would know when he or she saw it.

What is the duration of action?

The duration of action of a drug is the length of time that particular drug is effective. Duration of action is a function of several parameters including plasma half-life, the time to equilibrate between plasma and target compartments, and the off rate of the drug from its biological target.

Why is drug education so important?

Drug education enables children, youth and adults to develop the knowledge, skills, and attitudes to appreciate the benefits of living healthily (which may or may not include the use of psychoactive substances), promote responsibility towards the use of drugs and relate these to their own actions and those of others.

What is the purpose of drug?

In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being.

Which is an action of a drug?

The action of drugs on the human body is called pharmacodynamics, and what the body does with the drug is called pharmacokinetics. The drugs that enter the human tend to stimulate certain receptors, ion channels, act on enzymes or transporter proteins. As a result, they cause the human body to react in a specific way.

What is a drug related problem?

Drug-related problems (DRPs), defined as ‘an event or circumstance involving drug therapy that actually or potentially interferes with desired health outcomes’,1 constitute a frequent safety issue among hospitalised patients leading to patient harm and increased healthcare costs.

What is the meaning of drug abuse prevention?

What is duration of a drug?

Introduction. The duration of action of a drug is known as its half life. This is the period of time required for the concentration or amount of drug in the body to be reduced by one-half. We usually consider the half life of a drug in relation to the amount of the drug in plasma.

How can I get rid of drugs at home?

Disposing medicines in household trash: If a take back program is not available, almost all medicines, except those on the FDA flush list (see below), can be thrown into your household trash. These include prescription and over-the-counter (OTC) drugs in pills, liquids, drops, patches, and creams.
