Abstract:
Olanzapine (OLZ) is an antipsychotic agent and is a thienobenzodiazepine derivative. It is used either in combination with other drugs like carbamazepine, simvastatin, and clozapine or as a single drug. The present work is mainly focused on various approaches for OLZ analysis in bulk drugs as well as on their pharmaceutical formulations. It is also focused on various bioanalytical methods used for analysis. Our survey showed that many analytical techniques were carried out using UV spectrophotometry, MS, LC-MS/MS techniques, and chromatographic techniques like HPLC and high-performance thin layer chromatography in both bulk and solid dosage forms. Bioanalytical techniques were also performed using human plasma or serum. The analysis was carried out either for a single drug or for a combination of drugs. This review shows the rate of use of the different methodologies for OLZ analysis. A considerable amount of information was collected and utilized for the strategies.

The model approach uses mathematical models to describe changes in drug concentration over time. Pharmacokinetic models help characterize drug behavior in patients, predict drug concentration in the body fluids, calculate optimum dosage regimens, and evaluate the risk of toxicity. However, ensuring that the model fits the experimental data accurately...
