Study Notes
Definition and Scope of Pharmacology
- Pharmacology is the study of substances that interact with living systems.
- Substances studied in pharmacology primarily interact with the body to produce a response or alter a physiological function.
Pharmacokinetics
- Pharmacokinetics primarily describes the movement of substances within the body.
- It involves the study of absorption, distribution, metabolism, and excretion of substances.
Origin of the Term 'Pharmacology'
- The term 'pharmacology' is derived from two Greek words: 'pharmakon', meaning drug or medicine, and 'logos', meaning study or science.
Pharmacokinetic Activities
- Pharmacokinetics describes the activities of absorption, distribution, metabolism, and excretion of substances within the body.
Factors Affecting Drug Action
- Inadequate gastric acidity in neonates is a factor that modifies the action of drugs.
- Body surface area is a factor considered when prescribing drug dosages for children.
- Physiological factors, such as kidney or liver function, affect the dosage of certain drugs, like Chloramphenicol in newborns.
- Body weight and height are used to calculate body surface area, which is a factor in determining drug dosages.
- Interactions with other drugs are a factor that modifies drug action.
