Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
This chapter provides a brief review of the concepts of acid-base chemistry with its applications on drug molecules. It also highlights the significance of salt formations in pharmaceutical products. After studying this chapter, students will be able to: • Comprehend the Arrhenius, Brønstead-Lowry, and Lewis concepts of acids and bases. • Comprehend the ionization, factors controlling ionization, and the acids-base strengths. • Identify the acids and bases occurring in drug molecules and their significance. • Apply the concept of acid-conjugate base and base-conjugate acid in pharmacy. • Apply Henderson-Hasselbalch equation and in pharmacy and drug action and bioavailability. • Interpret pH partition theory and its significance in drug pharmacokinetics. • Illustrate the purpose of salt formation with drug molecules and the acidity or basicity of the salts.
Keywords:
Acids, Bases, Henderson-Hasselbalch equation, Ionization, Partition coefficient, pH partition theory, Salt formation, Solubility.
