Background: Sertraline Hydrochloride, an oral anti-depressant, has two chiral centers and its cis enantiomers and trans diasteromers are defined as related substances by United State Pharmacopoeia and British Pharmacopoeia. Introduction: A selective, stereospecific and economical high performance liquid chromatographic (HPLC) method was developed for the determination of sertraline enantiomeric forms. The HPLC-UV method was developed and optimized in the terms of system suitability parameters. Methods: The elution was made using a mixture of -cyclodextrin (-CD) and hydroxypropyl - cyclodextrin (HP -CD). Analysis was performed on a Zorbax SB C-18 column (250 x 4.6mm), 5μ with the mobile phase consisting of 170mM KH2PO4 containing -CD and HP -CD (pH: 3.0 with dil. H3PO4) and acetonitrile (75:25, v/v). Flow rate was kept at 1.0mL/min and the detection was carried out by UV at 220nm. Enantio-separation for sertraline was carried out using two different CDs (β-CD and HP β- CD) at different concentrations in the mobile phase. Results: Complete resolution of all the four isomers was achieved using 9mM β-CD and 15mM HP β- CD in the mobile phase. The development was optimized using central composite quadric model, where concentration of -CD and HP -CD were varied and resolution between trans diastereomeric impurities was calculated as a response. Conclusion: Resolution between any pair of isomers was found to be more than 2. Method development and optimization leading to the best resolution between the isomers of sertraline is described in detail.

Abstract A high performance liquid chromatographic (HPLC) method is described for the quantitative determination of primidone in tablets. A ground tablet sample is diluted directly in the mobile phase, at a concentration of about 1 mg/mL of primidone, mixed and deaerated, and filtered. The resulting solution is then quantitated by HPLC. The average spike recoveries for the 50 mg and 250 mg tablets were 101.2% and 99.0%, respectively. The average recovery for an authentic mixture formulated at the 250 mg level was 100.1% with a relative standard deviation of 0.45%.

Levetiracetam (LVT) is a widely used antiepileptic drug (AED). A less invasive sampling method for therapeutic drug monitoring (TDM) would be very useful particularly for children. Saliva has been shown as an adequate sample for TDM of some AEDs. Due to the high hydrophilicity of LVT its separation on common stationary phases is quite a challenge so that previous methods for determination of LVT in saliva employed either gradient high performance liquid chromatographic (HPLC) system or mass spectrometer as a detector. In this study the retention behavior of LVT on some common stationary phases was examined, with C8 being the most retentive. A simple isocratic HPLC method that is based on simple protein precipitation was developed and validated for the determination of LVT in saliva. The method was applied to a sample group of epileptic children for the purpose of assessing potential correlation with plasma LVT levels and to investigate patient’s compliance. The results confirmed a reasonable correlation between plasma and salivary levels of LVT (R = 0.9) which supports the use of saliva for TDM of LVT. The study also revealed a significant percentage of epileptic patients having LVT levels below the estimated therapeutic range.
