Determination of related substances impurities in drugs by ich guide lines l.jpg

DETERMINATION OF RELATED SUBSTANCES & IMPURITIES IN DRUGS BY ICH GUIDE LINES

BY

M.PAUL RICHARDS


Introduction l.jpg

INTRODUCTION

  • ANALYTICAL PROCEDURES.

  • RESIDUAL SOLVENTS

  • ICH GUIDELINES

  • CO - SPONSORS OF ICH.

  • WHO GOVERN ICH

  • AREAS OF ICH GUIDE LINES.

  • THE STATUS OF ICH GUIDE LINES.


Analytical procedures l.jpg

ANALYTICAL PROCEDURES

  • Suitable for detection & quantification of degradation products. (HPLC & TLC).

  • For determination of related substances & degradation products.

  • Sample stored under stress conditions (light , heat, humidity, acid/base hydrolysis & oxidation)


Slide4 l.jpg

  • Other peaks should be labelled in the chromatogram & discussed in documentation.

  • Quantification limit is >/ the reporting threshold.

  • Deg.product should be compared with analytical response of Deg.product to that of appropriate REFERENCE STD.

  • REFERENCE STD : Control of deg .products should be

    evaluated & to their Intended use.


Slide5 l.jpg

  • Should be validated for specified & unspecified conditions & used to estimate ,identify & unidentify deg.products.

  • Diff.used during development proposed to commercial

    product should be discussed.


Residual solvents l.jpg

RESIDUAL SOLVENTS

  • Determine by using C.Technique such as GC.

  • Those describe in pharmacopoeias can be used for determination .

  • If only class 3 solvents are present ,non specific method

    used on loss on drying.


For isolating and identifying process related impurities using l.jpg

For Isolating and Identifying process related Impurities using

  • MS

  • NMR

  • HPLC

  • FTICR-MS

  • LC-MS.


Ich guidelines international conference on harmonization l.jpg

ICH GUIDELINES (INTERNATIONAL CONFERENCE ON HARMONIZATION)

  • DEF: This is a process by which the organising authorities of the US, European commission Japan & experts from pharmaceutical industries & the trade association in the three region are brought together to discuss about the scientific and technical aspects of PRODUCT REGISTRATION.


Objective l.jpg

OBJECTIVE

  • To discuss scientific & technical aspects of medicinal product registration.

  • Discuss b/w regulatory authorities and the pharmaceutical industry on the real and perceived differences.

  • To identify an area where modification in technical requirements could lead to a more economical use .

  • To make recommendations on practical ways.

  • To achieve greater harmonisation in interpretation & application of technical guidelines & requirements for registration.


Co sponsors of ich l.jpg

CO SPONSORS OF ICH.

  • EC-EU.

Functions l.jpg

FUNCTIONS.

  • HAS EQUAL PARTICIPATION IN THE PROCESS & EACH HAS TO SEAT ON THE STEARING COMMITTEE , WHICH OVERSEAS HARMONISATION ACTIVITIES.
