GMP : Pharmaceutical Tablet Manufacturing

Explore compressible solid dosage forms, their classification, and manufacturing by compression into tablets and capsules, with variations such as coated, effervescent, and enteric tablets and powders for suspension or solution.

Explore how tablets, including chewable and effervescent forms, are designed and compressed from drug substances and excipients, with coatings, colorants, and disintegration and dissolution characteristics in mind.

Explore sugar coated, film coated, and enteric coated tablets, understanding how film coatings protect the core, improve taste and stability, and enable delayed release in the GI tract.

Explore how diluents, such as lactose, microcrystalline cellulose, and dibasic calcium phosphate, influence tablet manufacturing through inertness, non-hygroscopic and hydrophilic properties, and API compatibility across direct compression and granulation.

Promote cohesiveness in powders and enable granule formation, binders enhance tablet integrity and powder flow. Add binders as dry powders or solutions, including povidone, hydroxypropyl cellulose, and starch.

Disintegrants in solid dosage forms overcome cohesion by drawing water. Spa disintegrants like sodium starch glycolate, cross povidone, and croscarmellose sodium promote swelling to boost dissolution and in vivo performance.

Highlight how lubricants reduce friction between tablet surfaces and tooling during compression and ejection, their hydrophobic nature and low external phase usage protect disintegration and dissolution, with magnesium citrate.

Learn direct and indirect compression for solid dosage forms, compare wet coronation and dry coronation processes, and evaluate roller compaction and slugging to produce flowable, compressible granules.

Direct compression, or dry mixing, blends diluents, binders, disintegrants, active ingredients, lubricants, and coating agents in an intermediate bulk container to produce a homogeneous, compressible powder for tableting.

Employ direct compression, or dry mixing, for a simplified, faster tablet manufacturing method with no wetting or heating, improving stability and cost savings while accelerating disintegration for poorly soluble drugs.

Identify the disadvantages of direct compression in tablet manufacturing, including high-dose compressibility, limited binding excipients, low-dose uniformity issues, and segregation risks that drive granulation and blending needs.

Define general granulation techniques, contrast wet and dry granulation, and explain how weighing ingredients, granulation, grinding, compression, and coating build tablet forms.

Granulation creates granules with desired density and flow, reducing segregation and improving content uniformity in tablet compression. It also enhances process robustness and compaction by increasing plasticity of the granules.

Granulation involves many processing steps, increasing time, labor, space, and energy costs. It raises temperature and moisture sensitivity concerns and risks solvent incompatibilities, affecting yield and dissolution.

Examine how tablet compression turns powder or granules into tablets using a hopper, punches, and die, covering feeding, compaction, ejection, single and rotary presses, and defects like capping, lamination, cracks.

Explore film coating in pharmaceutical tablet manufacturing, covering aesthetic appearance, masking tastes and colors, protection from light and moisture, and the core components and steps of the coating process.

Explore designing, developing, and optimizing the film coating process for pharmaceutical tablets. Learn about equipment choices, weight gain, wetting and drying balance, and spray parameters from setup to cooling.

Explore film coating equipment for pharmaceutical tablets, including pan types (solid, semi-perforated, fully perforated), spray guns, and air handling with HEPA filtration for uniform coating.
