What is Physical Pharmaceutics I?
Physical Pharmaceutics-I deals with the physical and chemical principles that govern the behavior of pharmaceutical systems. It helps students understand how drugs and dosage forms interact with physical environments and how these principles influence formulation, stability, and drug performance.
These notes will help you understand topics like:
Matter, Properties, and States: Intermolecular forces, state of matter, and phase transitions
Micromeritics: Particle size, shape, surface area, porosity, and their measurement methods
Rheology: Flow properties of liquids and semisolids, Newtonian and non-Newtonian behavior
Surface and Interfacial Phenomena: Surface tension, adsorption, wetting, and surfactants
Complexation and Protein Binding: Types of complexes, stability constants, and biological significance
Buffer Solutions: pH, buffer capacity, preparation, and pharmaceutical importance
Solubility and Distribution Phenomena: Factors affecting solubility, partition coefficient, and applications
Thermodynamics in Pharmacy: Energy, work, enthalpy, and free energy concepts relevant to drug stability
