Drug acts
Food and drug act (FDA)
- All drugs sold in Canada must be approved under this act. FDA is to protect the public health hazards and fraud from
the sale of food, beverages, drugs, medical devices, and cosmetics
Controlled drug and substance act
- Defined drug abuse and the drugs according to potential abuse. The drugs are classified into schedules
Pharmacodynamics
The branch of pharmacology concerned with the effects of drugs and the mechanisms of their drug
- How the drug affects the body
Pharmacokinetics
The branch of pharmacology concerned with the movement of drugs within the body
- How the body effects the drug
- Example: the first pass effect, the liver metabolizes the drug reducing the dose working in the body
Nurses’ role in pharmacology
Nurses are responsible for:
- Administering the drug
- Assessing the drug affect
