Physical Pharmaceutics by Manavalan and Ramasamy: A Comprehensive Review
Physical pharmaceutics is a branch of pharmacy that deals with the fundamental principles and properties of drug substances and dosage forms. It helps to understand how drugs behave in different states of matter, how they interact with each other and with the environment, how they can be formulated into effective and stable products, and how they can be delivered to the target site in the body.

What is Physical Pharmaceutics?
Physical pharmaceutics is the study of the physical and physicochemical aspects of drugs and pharmaceutical systems. It involves the application of physics, chemistry, mathematics, and engineering to understand and manipulate the properties and behavior of drug substances and dosage forms.
Physical pharmaceutics is important for several reasons:
It helps to design and develop new drugs and drug delivery systems that are safe, effective, stable, and convenient.
It helps to optimize the performance and quality of existing drugs and drug products by controlling their physical characteristics, such as particle size, shape, surface area, porosity, density, viscosity, elasticity, etc.
It helps to predict and prevent potential problems that may arise during the manufacturing, storage, distribution, and administration of drugs and drug products, such as degradation, precipitation, aggregation, crystallization, polymorphism, phase separation, etc.
It helps to evaluate and test the quality and stability of drugs and drug products by using various analytical techniques, such as microscopy, spectroscopy, chromatography, calorimetry, etc.
It helps to comply with the regulatory requirements and standards for drugs and drug products by following the guidelines issued by various authorities, such as ICH (International Council for Harmonisation), USP (United States Pharmacopeia), BP (British Pharmacopeia), etc.
