3. ICH-Q7 & ICH-Q11
Introduction

4. “Platform Manufacturing”
How many people are aware with this terminology?

5. Can all give
same quality of
product?
There are different types of rice

6. Let’s imagine a
scenario and think …

7. Water coming from supplier
Stored in a tank before entering
in API Mfg industry
Tank has a small hole
Will it have
impact on
API Quality?

12. Staring
Material
Intermediate API
Simple
Complex

13. What is a Starting Material?
 Contributes an important structural part of the API
 Compound well defined in chemical literature (name, chemical
structure, chemical/physical properties, and impurity profile)
 Synthesized by commonly known process
Q7

14. Re-defining Starting Material
Marks the Start of the Manufacturing Process
 Manufacturing steps before are not described
 Manufacturing steps before need not be performed with GMP
 Changes in manufacturing steps before need not be reported to Agency
Each Branch of a Synthesis will begin with One or More Starting
Materials
Q7

15. What is an API?
A substance or compound that is intended to be used in the
manufacture of a pharmaceutical product as a therapeutically
active compound (ingredient)
Q7

16. API- DS, Characteristics
Elucidation of structure
Impurities
Specifications & its justification
Analytical procedure
Analytical method validation
Q7

17. API- DS, Characteristics
Potentially genotoxic impurities in DS
Atorvastatin exists in crystalline and
amorphous forms. The amorphous forms
are very sensitive to oxidation giving
various epoxide degradation products that
is considered a structural alert.
Q7

18. API- DS, Characteristics
Potentially genotoxic impurities in DS
Oxcarbazepin: Acridine derivatives are
potential degradation product of
oxcarabazepin that have some DNA
binding capabilities

are not mutually exclusive
One can use any of them or
both of them together

24. Take Home Message
Level of scientific knowledge will
determine the confidence and predict the
regulatory flexibility
