Study Notes

Biopharmaceutics

  • Biopharmaceutics studies factors that influence the behavior of drugs in the body, specifically their formulation, stability, manufacture, and effectiveness.
  • Key aspects analyzed include drug product design, stability, manufacturing processes, and drug release mechanisms.
  • Focus on the interaction between the drug's physical and chemical properties, the formulation, and the administration route affects systemic drug absorption.
  • Delivery methods can target localized effects or facilitate systemic absorption.

Introduction

  • Drugs are defined as substances for diagnosing, curing, mitigating, treating, or preventing diseases.
  • They come in various dosage forms: solids (tablets, capsules), semisolids, liquids, suspensions, and emulsions, suitable for systemic or local activity.
  • Drug products serve as delivery systems that release the drug, ensuring therapeutic effects while considering patient needs like palatability and safety.

Drug Product Performance

  • Drug release from products is essential for achieving local action or systemic therapeutic levels.
  • Bioavailability, a critical concept, indicates the rate and extent of active drug reaching systemic circulation, reflecting its effectiveness.

Pharmacodynamics

  • Studies the relationship between drug concentration at the target site (receptor) and pharmacologic responses, including biochemical and physiological effects.
  • Describes the effects drugs produce in the body, emphasizing the mechanisms behind these effects.

Toxicokinetics

  • Involves applying pharmacokinetic principles to evaluate drug safety through dose-related exposure studies in animals.

Clinical Toxicology

  • Focuses on adverse effects produced by drugs and toxic substances (poisons) on the body.

Pharmacokinetics

  • Concerned with the kinetics of drug absorption, distribution, metabolism, and excretion.
  • Aims to understand how drugs move through the body and are eliminated, contributing to the overall pharmacodynamic process.

Bioavailability

  • Measures the rate and extent to which an active drug reaches systemic circulation, indicating its therapeutic potential and effectiveness.
