Study Notes
Branch of Medicine and Disease Prevention
- Preventive medicine is concerned with the prevention of disease and treatment of suffering.
Drugs and Medications
- A drug is a substance used to diagnose, cure, or prevent disease, whereas a medication is a drug prescribed to treat a specific condition.
- Over-the-counter (OTC) drugs can be obtained by patients without consulting a healthcare provider.
Regulation of Natural Health Products
- The Natural Health Products Directorate (NHPD) regulates natural health products in Canada.
Drug Development and Clinical Trials
- Phase III clinical trials test the efficacy and safety of a drug in a large population.
Purpose of Drug Regulations
- The purpose of drug regulations is to ensure the safety and efficacy of medications.
Pregnancy Categories and Medication Use
- The US FDA assigns pregnancy categories to indicate the potential risks of medication use during pregnancy.
- Particular caution is recommended during the first three months of pregnancy due to the critical period of fetal development.
- Teratogens are substances that can cause birth defects or harm to the fetus.
- Alternative therapies should be considered before initiating pharmacotherapy during pregnancy to minimize risks.
Pharmacotherapy and Pregnancy
- The main consideration when testing drugs for use during pregnancy is the potential harm to the fetus.
- Pharmacotherapy during pregnancy must be undertaken with great caution due to the potential risks to the fetus.
- Cognitive development is an important consideration when prescribing medications to a patient.
Route and Formulation of Medication
- Factors such as patient age, weight, and medical condition may impact the decision on the route and formulation of medication.
Patient Considerations
- Healthcare providers must consider a patient's ability to excrete medications, pre-existing or developed conditions, and their ability to appreciate the need for a medication or its associated risks.
Pharmacokinetics
- The primary site for drug metabolism is the liver.
- Drug distribution refers to the movement of a drug throughout the body.
- The blood-brain barrier prevents many drugs from reaching the brain tissue.
- The therapeutic index measures the safety of a drug by comparing the dose required for therapeutic effect to the dose that produces toxic effects.
Ideal Drug Characteristics
- An ideal drug should have the ability to produce change in clients.
Drug Information
- The FDA shares drug information with healthcare providers and consumers upon approval.
Time-Response Relationships
- The goal of time-response relationships in pharmacokinetics is to determine the duration of a drug's effect.
Dose-Response Relationships
- The graded dose-response relationship describes the varying effects of a drug at different doses.
