Study Notes
Pharmaceutical Manufacturing - Powders
- Powders are solid or mixtures of solids, reduced to a finely divided state.
- Used internally (oral, nasal, insufflation) and externally (topical).
- Advantages: flexibility in compounding, dose adjustment, good chemical stability.
- Disadvantages: time-consuming to prepare, potential for dosage inaccuracy, unpleasant taste.
- Types include: topical, insufflated, medicated, bulk, divided.
- Bulk powders are often mixed with other materials before administration (e.g., powder for suspension).
- Small scale powder preparation methods: trituration/comminution, pulverization, levigation.
- Large scale preparation methods: Fitzmill comminutor, tumbling, mixing/mixer, V-blender.
Pharmaceutical Manufacturing - Tablets
- Tablets are circular or disk-shaped, can resemble capsules (caplets).
- Designed to be easier to swallow.
- Types: compressed, sugar-coated, film-coated, enteric-coated, effervescent, chewable, dispersible, sustained-release, multiple, sublingual, buccal.
- Excipients include: diluents (increase bulk), binders (glue ingredients), disintegrants (dissolve in water), lubricants (reduce friction).
Pharmaceutical Manufacturing - Granulation
- Wet granulation is the most common agglomeration process in the pharmaceutical industry.
- Powder blend is mixed with a granulating liquid.
- Important steps: weighing/blending, preparing dampened powder/mass, screening dampened powder/mass, drying the granulation, sizing the granulation.
- Dry granulation: powder mixture is compressed without heat or solvents, least desirable method.
- Two methods: slugging (repressing), milling.
Pharmaceutical Manufacturing - Granulators & Mixers
- Rapid Mixer Granulator: prevents segregation of ingredients, improves compression characteristics.
- Fluid Bed Dryer Machine: granulation process for drying, correct moisture content.
- Ribbon Mixer Machine: efficient and versatile for mixing dry granules and powders.
- Double Cone Blender: sigma type blades rotate in the same direction.
Pharmaceutical Manufacturing - Capsules
- Capsules can be tasteless, odorless, easy to administer, and visually appealing.
- Hard shell capsules: typically made of gelatin containing dry, powdered ingredients or miniature pellets.
- Soft shell capsules: primarily for oils or ingredients dissolved/suspended in oils.
- Ingredients include: gelatin, water, preservatives, colors, opacifiers, flavoring agents, sugars, acids, plasticizers.
Pharmaceutical Manufacturing - Solutions
- Solutions are liquid preparations with one or more chemical substances dissolved in a solvent.
- Types include: aqueous (water-based) and non-aqueous (other solvents).
- Classified by use for: oral, otic, ophthalmic, topical.
- Classified by composition/use: syrups, elixirs, spirits, tinctures, injections.
- Solvents: alcohols, glycerin, propylene glycol, water.
- Ingredients used to increase stability or solubility: antioxidants, buffering agents, antimicrobials.
Pharmaceutical Manufacturing - Manufacturing Considerations
- Raw Materials: must conform to specifications (identity, potency, free from contaminants).
- Water: extremely important, and must meet specific USP requirements (e.g., sterilization, quality control).
- Processes: carefully consider techniques like sterilization, filtration, preventing contamination.
Pharmaceutical Manufacturing - Filling & Packaging
- Automatic machines: used for filling and sealing bottles, vials, ampoules with appropriate quality control and safety checks.
- Volumetric filling: delivers premeasured volume to each container.
- Timed flow filling: determines the fill volume by controlling the time.
- Gravimetric filling: filling method for viscous products, ensuring consistent volume in each container.
- Vacuum filling: uses vacuum to control the flow.
Pharmaceutical Manufacturing - Blister Packing
- Blister packing machines: automatic machines for packing small and regular shaped products like tablets, capsules.
- Processes involved: blister forming, product feeding, sealing.
Pharmaceutical Manufacturing - Other Equipment
- Rotary Die Machine: for encapsulating flows by gravity; the process is for the gelatin sheets feeding to the die pocket of the die roll, then being continuously filled with liquid or paste and the sealed capsule cut by the mechanical.
- Rotary Tablet Press Machines: presses powder to form tablets.
- Capsule Filling Machine: fills the capsule shell with the desired substance efficiently.
- High-Speed Automatic Bottle Filling & Cap Sealing Machines: for filling and capping bottles, with various filling capacities per minute.
- Rotary Bottle Washing Machine: for cleaning and washing.
- Bottle Unscramblers/Labelling Machines/Carton Machines: for final packaging processing stages, like unscrambling bottles, labeling, and cartonization.
