Biopharmaceutics
- Biopharmaceutics examines the relationship between a drug's physicochemical properties, dosage form, and route of administration on its systemic absorption rate and extent.
- Key factors influencing biopharmaceutics:
- Drug stability within the drug product
- Drug release from the drug product
- Dissolution/release rate of the drug at the absorption site
- Systemic absorption of the drug
Pharmacokinetics
- Pharmacokinetics is the science of the kinetics of drug absorption, distribution, and elimination (excretion and metabolism).
- Pharmacokinetics describes how the body handles a drug.
- The processes in Pharmacokinetics in sequence are: Drug release and dissolution, Absorption, Distribution, Elimination (Excretion and Metabolism). Pharmacologic or clinical effect is the result.
In-vitro and In-vivo Methods
- In-vitro methods use laboratory procedures without involving humans or animals.
- In-vivo methods use human subjects or animals.
Clinical Pharmacokinetics
- Clinical pharmacokinetics applies pharmacokinetic methods to drug therapy.
- Optimizes dosing strategies based on patient's condition.
- Accounts for individual variations in drug metabolism and response (e.g., age, gender, genetics, etc).
- Aims to achieve optimal dosing regimens for maximum efficacy and minimum toxicity.
Pharmacodynamics
- Pharmacodynamics is the relationship between drug concentration at the site of action (receptor) and the resulting pharmacologic/toxic response.
- Drug-receptor interaction initiates sequence of molecular events leading to response.
- Pharmacokinetic-pharmacodynamic models predict drug intensity and duration.
Toxicokinetics
- Toxicokinetics applies pharmacokinetic principles to design, conduct, and interpret drug safety studies and dose-related exposure.
- Enables the investigation of dose-response relationships for toxicity.
- Provides data for understanding and extrapolating animal results to humans.
- Can involve preclinical and clinical drug development.
Clinical Toxicology
- Clinical toxicology studies adverse effects of drugs and toxic substances in the body (poisons).
- Pharmacokinetics can vary significantly in overdosed patients compared to therapeutic doses.
- High doses can lead to enzyme saturation, resulting in non-linear pharmacokinetics.
