Definition: A pharmaceutical powder is a mixture of finely divided particle of drugs or excipients in dry form.
• Particle Size: Difference in size >> efficient packing via interlocking effects Particle Size Distribution (PSD) in a powder sample Affects powder bulk flow Small size particles Vs. large size particles
• Particle solubility Affects drugs disintegration and dissolving
• Particle Shape Isometric: round shape >> best for hard capsule Anisometric: needle-shaped >> different particle orientation >> irregular fluidity
• Particle Adhesion Dissimilar particles stick to one another to surfaces. Therefore, substances break powder uniformity
• Particle wettability Critical to drug substance release
• Flowability Ability of powder to flow in an equipment. Depends on physical properties of powder and the used equipment i.e. bulk density, friction permeability, forces, porosity.

• Tamp filling system into capsule size one
• Dosator nozzle system into capsule size zero
• Powder in dosator nozzle can be calculated
Hard Capsule filling
• Three different bed heights used
• Pin setting tested for each bed height and ranged from no compression to firm compression
Tamping filling machine
• Acceptable filling can be achieved and independent of type of machine
• Tamp filling better for coarser granules and no solid plug can be formed
• Dosator nozzle filling machine- plug formed but denser than maximum bulk density
Tamping filling machineCont’
Disadvantage: the large variety of possible machine settings.

Accogel process- process for manufacturing of soft gels with powders or granules
Measuring roll rotate directly over the die roll and pockets in the 2 rolls are aligned Measuring roll powder or granular fill material under vacuum
Die roll plasticized sheet under vacuum
Sealing roll second gelatin sheet applied to form other half of capsulePressure developed between die roll and sealing roll seals and cuts out the capsules
Drying process
Capsule need to be dried hard for packaging. Tumble dryer used for soft capsule about 30 to 40 min remove 25%
transferred to drying room and it takes about 24-48 hours
