ASSAY TECHNIQUE VALIDATION OF THE ADAMANTANE DERIVATIVE DRUG IN INJECTION DOSAGE FORM BY GLC

The main purpose of development pharmaceutical dosage form is to find out the in vivo and in vitro behavior of dosage form. This challenge is overcome by implementation of in-vivo and in-vitro correlation. Application of this technique is economical and time saving in dosage form development. It shortens the period of development dosage form as well as improves product quality. IVIVC reduce the experimental study on human because IVIVC involves the in vivo relevant media utilization in vitro specifications. The key goal of IVIVC is to serve as alternate for in vivo bioavailability studies and serve as justification for bio waivers. IVIVC follows the specifications and relevant quality control parameters that lead to improvement in pharmaceutical dosage form development in short period of time. Recently in-vivo in-vitro correlation (IVIVC) has found application to predict the pharmacokinetic behaviour of pharmaceutical preparations. It has emerged as a reliable tool to find the mode of absorption of several dosage forms. It is used to correlate the in-vitro dissolution with in vivo pharmacokinetic profile. IVIVC made use to predict the bioavailability of the drug of particular dosage form. IVIVC is satisfactory for the therapeutic release profile specifications of the formulation. IVIVC model has capability to predict plasma drug concentration from in vitro dissolution media.

Objective: This study was conducted to analyze and evaluate the prevalence of prescription errors, to optimize the medication effectiveness and patient safety and to encourage the rational prescribing practices. Method: sample of 250 prescriptions was randomly collected from outdoor hospital pharmacy (n=157) and from community pharmacy (n=93) and analyzed manually to estimate the prevalence of prescription errors. Results: Results calculated by using SPPS Version 23 and MS Excel 2013 are as follow; 41.4% prescription collected from outdoor hospital pharmacy presented significant prescribing errors while 54.7% in sample collected from community pharmacy. The prescriptions were segregated and errors were estimated using following parameters; dose, dosage form, dosing frequency, drug-drug interactions, spelling, and duplication of generic, therapy duration and unnecessary drugs. Conclusion: The prevalence of prescribing errors in sample of community pharmacy was 12.37% greater than found in prescriptions of hospital pharmacy. The prevalence of prescription errors can be reduced by physician education, using automated prescribing systems and immediate review of prescription by pharmacist before dispensing of prescription items to patients.
