CHARACTERIZATION OF DRUGS. Biological systems are built from chiral building blocks, proteins and peptides are built from chiral amino acids, polysaccharides are built from chiral monosaccharides, and DNA is chiral due to its α‐helix structure. Drug properties comprise the structural, physicochemical, biochemical, pharmacokinetic (PK), and toxicity characteristics of a compound. The stoichiometry of drug/CD complexes is most frequently 1:1. The use of nanotechnology to optimize the delivery of drugs and diagnostic molecules is increasingly receiving attention due to the enhanced efficiency provided by these systems. Cram.com makes it easy to get the grade you want! These properties may provide: A rationale for formulation design Support the need for molecular modifications Quantitation of physical and chemical properties that will assist in developing: Stable Safe Effective formulation with: Maximum Bioavailability … PHYSICOCHEMICAL PROPERTIES OF DRUG MOLECULES By Dr. S.
