Slide 1

Pharmaceutical Development Quality determinations and final result testing with accentuation on the advancement of a biased disintegration testing technique Presented by: Birgit Schmauser, drug specialist, PhD

Slide 2

Pharmaceutical improvement Objectives of the introduction Role of value details Setting and defense of acknowledgment criteria Selection of test systems Establishment of a disintegration testing strategy Discrimination of plans Discrimination of assembling execution Identification of strength issues

Slide 3

Introduction API Establishing compound equality with Innovator API Stress solidness testing Identify basic synthetic quality properties Developing a steadiness showing systematic technique Establishing appropriate acknowledgment criteria FPP Establishing identicalness of execution with Innovator FPP Dissolution testing Developing a disintegration technique with prejudicial potential for changes in definition Establishing oppressive testing conditions and acknowledgment criteria

Slide 4

Discriminatory force of a disintegration technique Dissolution strategies ought to be tested amid improvement to exhibit that adjustment in plan impacts change in disintegration profile Source: T.G. Dekker, E. Swanepool, A-M. Redelinghuys & E.C. van Tonder – unpublished (Dissolution of Ethambutol-HCl and Isoniazid FDC)

Slide 5

Quality particulars Specification List of tests (test parameters) & reference to systematic techniques & proper acknowledgment criteria Specifications are basic quality principles Specifications are affirmed the nature of the API/FPP Specifications are not expected to completely describe the API/FPP Specifications are one a player in a quality control methodology of the API/FPP

Slide 6

Quality of pharmaceutical items P h a r m a c e u t i r o P c e s a s l V a l i p Q I n r o c d e u s a s a t e v D e l o i p l m o i e n t Design n t y P s l o r t M n m o c G e t s y S

Slide 7

Quality details The nature of APIs and FPPs is dictated by a very much controlled, approved assembling process Critical quality properties of info materials Critical process parameters Quality determinations are set up to guarantee that APIs and FPPs meet the pre-decided acknowledgment criteria got from exhaustive item portrayal amid advancement

Slide 8

Quality particulars of organic APIs The nature of APIs coming about because of natural procedures, for example, aging can't be adequately guaranteed by quality details PQIF Not reasonable for assessment of organic APIs Biological APIs are not subject of this introduction

Slide 9

Quality particulars General ideas Periodic testing/skip testing Pre-chosen groups/foreordained interims Justification/not as much as full calendar testing/post endorsement Release versus time span of usability detail Acceptance criteria/set of tests In-process tests Conducted amid assembling process/acknowledgment criteria Exclusion of tests Supported by improvement information Extractables/molecule measure/disintegration >> crumbling Revision of particulars in view of adequate bunch information

Slide 10

Quality determinations Pharmacopoeial benchmarks If suitable, pharmacopoeial test strategies and acknowledgment criteria ought to be utilized Alternative test strategies ( and acknowledgment criteria) might be utilized if similarity to or prevalence over the pharmacopoeial strategy is exhibited If pharmacopoeial completed item gauges are utilized consistence to each test parameter/method/acknowledgment criteria is comprehended

Slide 11

Quality details Specifications ordinarily excluded in authority compendia Residual solvents API and FPP (e.g. granulation, film covering) User prerequisites Particle measure Potential basic quality property recognized amid pharmaceutical advancement (Polymorphic structures)

Slide 12

Verification of compendial gauges Compendial test strategies API Verification of appropriateness with the fundamental exactness and accuracy Verification of specificity concerning polluting influences/degradants distinguished amid stress testing similar contamination profile FPP Verification of pertinence with the vital precision (framework!) and exactness Verification of specificity as to debasements/degradants distinguished amid stress testing

Slide 13

Verification of equivalence of in-house techniques with pharmacopoeial standard Abacavir sulfate PhInt In-house polluting influence profile ought to be confirmed by examination with PhInt strategy Comparison of maintenance times of PhInt polluting influences with chromatographic profile of test Verification that debasements B and D-F are not present (e.g. spike with polluting influence standard)

Slide 14

Quality details „A determination sets up the arrangement of criteria to which another medication substance or new medication item ought to adjust to be viewed as satisfactory for its proposed utilize " (ICH Q6A) … Justification ought to be displayed for every system and every acknowledgment basis included (ICH Q6A) Development information , pharmacopoeial principles, test information from preclinical and clinical reviews, comes about because of strength studies Range of expected scientific and assembling fluctuation

Slide 15

Quality determinations (FPP) General Characteristics and Tests Description Size, shape, shading Identification Identity of API (prejudicial) Assay Specific, security demonstrating Purity Degradation items (single un-recognized and distinguished; add up to) Residual solvents

Slide 16

Quality particulars (FPP) Particular Characteristics and Tests Oral strong measurement frames Dissolution (disintegration  80% in 15min at pH 1.2 – 6.8) Hardness/friability Uniformity of dose units Water content Microbial points of confinement

Slide 17

Quality determinations (FPP) Particular Characteristics and Tests Liquid dose frames for oral utilize (& powder and answer for reconstitution) Uniformity of dose units pH Microbial cutoff points Antimicrobial/Antioxidative additive substance Antimicrobial additive viability Extractables Dissolution (suspensions) Particle estimate conveyance Redispersibility (time required) Water content (powder and answer for reconstitution)

Slide 18

Quality details (FPP) Particular Characteristics and Tests Parenteral medication items Uniformity of dose units (powders for reconstitution) pH Sterility Endotoxins Particulate matter (unmistakable/subvisible particulates) Water content (powders for reconstitution) Antimicrobial/Antioxidant presevative substance Antimicrobial additive adequacy Extractables Osmolarity Particle measure dispersion (suspensions) Redispersibility (suspensions) Reconstitution time

Slide 19

Particular perspectives – FDC-FPPs WHO TRS 929, Annex 5, Guidelines for enlistment of settled measurements mix therapeutic items Emphasis on homogeneity of APIs in dose frame (≤ 25 mg/%) Homogeneity of mix before pressure (content consistency, PhInt, PhEur, USP)) Homogeneity of completed dose frame (content consistency, PhInt, PhEur, USP) Emphasis on sufficient contamination determinations Calculation with reference to the parent API or API with most minimal pinnacle territory rate Particular consideration regarding sufficient approval of diagnostic strategy Stability testing Impurity particulars in view of sufficient anxiety testing (Appendix 3) Emphasis on satisfactory disintegration testing More than one disintegration medium might be vital

Slide 20

Quality determinations - impediments Quality details are connected to a moderately little extent of a bunch and depend on representativeness of tests for a clump Well controlled assembling methodology (dose shapes) Acceptance criteria of value determinations are constrained by the execution/capacity of the technique utilized for testing Specifications (test, debasements) in light of deficient approval Impurity particulars and LOQ/reaction Assay particular and pinnacle virtue Impurities not secured by an expository strategy

Slide 21

Quality details - potential Unravel surprising related quality issues Quality issues distinguished by non-conformance to organoleptic parameters/appearance Odor (revelation of genotoxic esylates) Turbidity [Ba 2+ ( sort I-glass ! ) thus 4 - containing FPP-solution] Color (arrangement of debasement items)

Pediatric plans in PQ Isoniazid + Pyrazinamide + Rifampicin tablet 30mg+150mg+60mg Uncoated dispersible tablet with break line seventh EOI, antituberculosis meds Isoniazid + Rifampicin tablet 30 mg+60mg Uncoated dispersible tablet with break line seventh EOI, antituberculosis prescriptions

Slide 23

Quality details - Dissolution Performance Testing (ICH Q8) Performance can be considered as a marker of the conveyance of a medication from the measurements to the objective site (kind of measurement/course of organization) Performance observing of unit strong dose structures is normally tended to as the deterioration of the planning and the disintegration of the dynamic substance in a reasonable medium Disintegration testing ought to show the compelling separation of the strong definition after organization (execution of disintegrant) Routine execution of crumbling testing may not be fundamental if a disintegration test with worthy prejudicial power is incorporated into the completed item determination

Slide 24

Dissolution - ICH Q8 The real measure of medication freed from the measurements shape into a fluid supply in vitro is expected to mirror the in-vivo conduct of the item In-vivo conduct is subject to a few variables making in-vitro/in-vivo connection troublesome Investigation of disintegration attributes ought to routinely be connected to all strong dose frames at the advancement stage From such reviews a choice can be made with regards to the pertinence of the disintegration test to t
