    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.
