Introduction to Biopharmaceutics

Definition and Scope

• Biopharmaceutics studies the interrelationship between a drug’s physical, chemical, and biological properties and its absorption, distribution, metabolism, and excretion.
• It connects drug formulation with its therapeutic effects.

Importance in Drug Development and Therapy

1. Formulation Design:

   • Helps in developing dosage forms (e.g., tablets, capsules, injections) that enhance drug availability.

2. Therapeutic Efficacy:

   • Ensures optimal absorption for effective treatment.

3. Safety and Toxicity:

   • Prevents treatment failure due to low absorption and toxicity due to excessive absorption.

4. Personalized Medicine:

   • Aids in dose adjustments based on factors like gastric pH, organ function, and genetic variations.
