26
Q

Objectives of Granulation

A

Improve flowability and compressibility

27
Q

2 Methods of Granulation

A

Wet Granulation Method
Dry Granulation
Fluid Bed Granulation

28
Q

Most common method; addition of liquid binders to powders

A

Wet Granulation Method

29
Q

Advantages & Disadvantages of Wet Granulation

A

Advantages: Increased Compressibility
Improved Dissolution

Disadvantage: Not applicable to water/ moisture & heat sensitive (ex: Aspirin)

30
Q

Steps in Wet Granulation Method

A
  1. Blending of Ingredients
  2. Addition of Liquid Binder/Lubricating Fluid
  3. Screening the damp mass (Mesh #6-8)
  4. Drying the granulation (0.5 - 1%)
  5. Screening the dry granules (Mesh #12-20)
  6. Blending with lubricant and disintegrant
31
Q

Moisture Content of Wet Granulation

A

31-35%
Underwet – too soft
Overwet – too hard

32
Q

Rapid granulation and drying of batch, spraying of granulating solution onto the suspended particles, the dried rapidly in suspending air

A

Fluid Bed Granulation

33
Q

Powder mixture is compacted into large pieces and subsequently broken down into granules; for moisture and heat-sensitive materials

A

Dry Granulation / Precompression / Double Compression

34
Q

Example of substances produced in Dry granulation

A

Magnesium hydroxide
Aspirin
Ascorbic Acid
Acetaminophen
Thiamine

35
Q

Processes in Dry Granulation

A

Slugging/Slugging
Roller Compaction/Ribbon Blending

36
Q

A large tablet (slugs) is produced which is broken via milling to produce granular materials

A

Slugging/Rotary Compaction

37
Q

Instrument used in Slugging

A
