2. What is supac ?
In the process of developing the new product ,
the batch size used in earliest human studies are
small.
The sizes of the batch is gradually increased(scale
up).
The scale up and the changes made after approval
in the composition, manufacturing process ,
manufacturing equipment and change of site have
become known as scale up and post approval
changes (supac).
3. SUPAC
The FDA has issued various guidance for supac changes
designated as:
Supac-IR ( for immediate release solid oral dosage
form).
Supac-MR (for modified release solid oral dosage
form).
Supac-SS (for non sterile semisolid dosage form
including creams, ointments, gels and lotions).
4. Supac guidelines-define

• Application/compendial tests
• In-vitro dissolution/release
• In-vivo
5. Level of changes
Likelihood of impact on formulation quality and performance:
• Level 1: Those changes that are unlikely to have any detectable
impact on formulation quality and performance.
• Example- Changes in the colour, flavours, Changes In the
excipient expressed as percentage (w/w) of total formulation,
less than or equal to the following range .
6. • Level2: Changes are those that could have significant
impact on the formulation quality and performance.
• Example -Changes in the technical grade of excipient
(Avicel PH102 vs Avicel PH200) Changes expressed as
percent (w/w of total formulation) .
7. • Level3:
Level 3 : changes are those that are likely to have significant
impact on formulation quality and performance.
Example -Any qualitative or quantitative excipient changes a
narrow therapeutic drug beyond the range for level 1 and All
other drug not meeting the dissolution criteria as level 2.
8. These guidelines provide recommdation for post
approval changes in:
• In component or compostion
• The site of manufacture
• The scale up of manufacture
• The manufacturing(process and equipment)
9. Component and composition
changes
SUPAC-IR:
Focus on changes in the amount of excipients in the
drug product.
SUPAC-MR:
Excipient critical or non critical to the drug release. -
Changes in non release controlling excipients - Changes
in release controlling excipients.
SUPAC-SS:
Changes in preservative.
11. SUPAC-IR
• 1)Focus on the changes in amount of
excipients in the drug product.
• 2)Not focus on change in the amount of the
drug substance .
