2. API vs Excipients Difference
Typical Attributes API Excipient
End users - Pharmaceutical company
- Cosmetic companies
- Industrial
- Cosmetic
- Food
- Pharmaceutical
Manufacturing - Batch (usually)
- Small volume (usually <1000 kg )
- Batch or continuous
- Large volume
Synthesis - Synthesis of specific molecular
entity
- Synthesis of predominant
molecular entity
- Extraction , processing and/or
purification of naturally
occurring staring materials
3. Contt..
Typical Attributes API Excipient
Raw materials - Well – defined chemical
intermediate
- Harvested plant matter
- Animal products
- Minerals (mined)
- Fermentation
Composition - Typical processing reduces or
eliminates most impurities
- API = labeled entity +
impurities = 100 %
- Quantitative assay
- Typical API purification
techniques (e.g. crystallization ,
precipitation ) are not
applicable
- Excipients = normal labeled
entity + concomitant
components + additives +
residual processing aids +
impurities = 100 %
- Assay may no be available
4. Tablet Manufacturing Proses
Weight the sufficient amount of medicament, diluent, glidant,
binder etc.
Preparation of granules for compression by wet/dry method
granulation
Compression of granules into tablets & Coating of tablets
Packing of tablets
8. Flow Chart of Syrup Preparation
Add the sucrose to purified water
Heat to dissolve sucrose
Cool the solution
Add more purified water to make the required weight
Transfer into bottle , label and dispense
16. Tablet Coating
A tablet coating is a covering over a tablet , used to mask the task,
make it easier to swallow or protect the active medication inside .
Tablet coating with mixture of various substances such as resins ,
gums , inactive and insoluble fillers, sugars, waxes etc.
18. Sugar Coating
Sugar coating is the most conventional multistep coating
process.
As the name suggests this process involves application of
sugar (sucrose) based coating solution to the tablets.
Raw Material for Sugar Coating :
- Sugar & its Substituents – Glucose , lactose , isomalt,
sugar, sugar alcohol.
- Binder – Acacia , gelatin, PVP( polyvinyl pyrolidone)
20. Film Coating
Modern Approach Coating :
- Tablet
- Capsule or
- pellets
Raw Materials for Film Coating :
- Polymers
- Solvent
- Plasticizers
- Colorants
23. Enteric Coating
Enteric coating is a barrier that controls the location of oral medication is
the digestive.
Polymer used for Enteric Coating :
Cellulose Acetate Phthalate –
- It major disadvantage that is dissolves above PH-6.( stomach pH
1.5 to 3.5)
Acrylate Polymer –
- Two types commercial acrylic resins are..
i) Eudragit L ii) Eudragit S
24. • Eudragit L is available as an organic solution ( isopropanol) , solid or
aqueous dispersion .
• Eudragit S is available only as organic solution and solid.
Hydroxyproyl Methylcellous Phthalate (HPMCP)
- HPMCP – 55 (HP 55)
- HPMCP – 55s
- HPMCP 50 ( HP-50)
Polyvinyl Acetate Phthalate ( PVAP)
