Transaction. This lecture presents the basic concepts of pharmaceutical inorganic chemistry with emphasis on the description, mechanisms and uses of various pharmaceutical products which are clinically used to correct various body disorders. The major topics to be covered are acids and bases, intra and extra cellular electrolytes, the gastrointestinal agents and topical agents frequently employed in the conversion of drugs to chemical forms convenient to their product formulations.. Acid-base balance.  . * Acids are electrolytes that release hydrogen ions (H+) when they are dissolved in water.. * Bases are electrolytes are release hydroxide ions (OH-) when they are dissolved in water..
