PHARMACEUTICS AND DRUG DELIVERY SYSTEMS
In this course of study, the emphasis is on physico-chemical properties related to the design and formulation of dosage forms and optimal delivery of drugs to a site of action for therapeutic usefulness. This includes the role of biopharmaceutics, pre-formulation principles, drug stability and physical pharmacy in the development of safe and effective dosage forms. Bioequivalence, routes of administration and new design innovations are included.
TOPICS OF STUDY: PHARMACEUTICS & DRUG DELIVERY SYSTEMS
Solids and Solid Dosage Forms
The solid state
- Bonding - Van der Waal’s, hydrogen, covalent, electrostatic, metallic crystal systems and habits
- Crystallization - saturated and supersaturated solutions, crystal growth
- Crystallinity - amorphous solids, degree of crystallinity, crystal defects
- Polymorphism - effects on formulation, bioavailability
- Hydrates and solvates - hygroscopicity, deliquescence, phase diagrams, effects on formulation, bioavailability, lyophilization Eutectic mixtures, solid solutions, clathrates and inclusion compounds
Solid dosage forms
