Study Notes
Definition of Drug
- According to the World Health Organization (WHO), a drug is defined as any substance or product that is used to modify or explore physiological systems or pathological states for the benefit of the recipient.
Pharmacology Subfields
- Pharmacokinetics: the study of how the drug is absorbed, distributed, metabolized, and excreted.
- Pharmacodynamics: refers to the study of how the drug interacts with the body, including its effects on the body.
Pharmacotherapeutics
- Involves the study and application of the use of drugs to prevent and treat diseases.
- Primarily concerned with the study of adverse effects of drugs and how to develop a new drug.
Prescribing Drugs
- When prescribing drugs to pregnant women, the benefits and risks of the drug to the mother and the fetus should be considered.
- The dose of a drug should be decreased for patients with kidney or liver disease.
- The drug name should be written in the prescription in capital letters, with the dose and frequency specified (e.g. 'PARACETAMOL' 500MG Three times daily after food).
- Factors to be studied when prescribing drugs to patients include age, weight, and medical history.
Dosage Calculation
- For a child weighing 20 kg, the appropriate dosage of paracetamol (PCT) would be based on the child's weight.
- Paracetamol is typically given to a 6-month-old baby in a liquid or syrup form.
