Figg, Hao Zhu, Kenneth S. The concern today is not just to produce elegant and accurate dosage forms but also to ensure that optimum amount of drug reaches the target site at an optimal rate and its concentration is maintained for the entire duration of therapy. In this method, the primary aromatic amine is reacted with the sodium nitrite in acidic medium to form a diazonium salt.

Applications of Pharmacokinetic Principles Design of dosage regimens Individualization Monitoring drug therapy Questions The amine reacts with the nitrous acid to form nitrosamine, which is followed by the tautomerisation and the water molecule is lost to form the diazonium….

The steps involved in the non-aqueous titrimetric method are proposed by the Tomicek. Mathematical treatment of chapters on pharmacokinetics has been kept to at modest level in order not to overburden the students with the complexities of equations and formulae. Further the study was biopharnaceutics on comparing the impact of gelling agent polyvinyl pyrrolidone on drug release.

Review of general, organic, and biological chemistry, second edition. Fritz first used this method to distinguish the aromatic and aliphatic amines by using the perchloric acid as titrant. The optimized formulation of present study exhibited desired controlled drug release characteristics in the alkaline pH conditions and at acidic environment the drug dissolution was minimal as intended. This system ensures the drug release at the alkaline pH region where the drug has got maximum solubility.
