Study Notes
GMP Manufacturing: Pharmaceutical Production Process
- Azmy A Hamid, UKM Lecture, 9th December 2024
- Covered non-solid (cream) and solid (tablet) processes.
- Explores steps from raw material procurement to final packaging for creating safe and effective medicines.
Introduction to Pharmaceutical Production
- Research and Development: Scientists meticulously research and develop new drugs, testing efficacy and safety.
- Quality Assurance: Quality assurance systems guarantee the purity and potency of every batch, maintaining high standards.
- Regulatory Compliance: Strict regulations and guidelines ensure safety and efficacy for patients, governing the entire process.
Raw Material Procurement and Quality Control
- Sourcing: Pharmaceutical companies carefully select suppliers for high-quality raw materials.
- Testing: Raw materials undergo rigorous testing to meet stringent specifications.
- Documentation: Complete documentation is maintained throughout the process to track material history.
Formulation and Compounding
- Active Pharmaceutical Ingredients (APIs): Active ingredients are carefully weighed and measured to ensure precise dosage.
- Excipients: Inactive ingredients are added for stability, binding, and other purposes.
- Mixing and Blending: Thorough mixing ensures uniform distribution of ingredients for consistency.
Dosage Form Preparation
- Tablets: Solid dosage forms, typically compressed powders, for oral administration.
- Capsules: Powder, liquid, or granules encased in a gelatin shell, for swallowing.
- Liquids: Solutions, suspensions, or emulsions for oral, topical, or injectable use.
Tableting and Capsule Filling
- Granulation: Powders are granulated to improve flowability and compressibility, affecting tablet shape.
- Compression: Granules are compressed into tablets using a specialized machine.
- Capsule Filling: Powders or granules are filled into capsules using automated machines.
Coating and Packaging
- Coating: Tablets may be coated to mask taste, improve stability, or enhance appearance.
- Packaging: Tablets, capsules, or liquids are packaged into bottles, blisters, or vials.
- Labeling: Labels with product name, dosage, and other information are applied.
Sterilization and Aseptic Processing
- Sterilization: Eliminating microorganisms from products or equipment through heat, radiation, or filtration.
- Aseptic Processing: Manufacturing processes conducted under sterile conditions to prevent contamination. Specifically relevant for injectables; "more strict" & higher clean room grade.
- Quality Control: Regular monitoring and testing ensure sterility and safety throughout the process.
In-Process Quality Checks
- 100% Purity: Ensuring the product contains only the intended ingredients.
- 100% Potency: Confirming the strength and effectiveness of the product.
- 100% Stability: Verifying that the product maintains its quality over time.
Regulatory Compliance and cGMP Standards
- FDA Guidelines: The U.S. Food and Drug Administration (FDA) sets strict guidelines for pharmaceutical manufacturing.
- Good Manufacturing Practices (cGMP): GMP standards are essential for ensuring product quality, safety, and efficacy.
- Quality Auditing: Regular audits ensure compliance with regulations and internal quality standards.
Pharmaceutical Semisolids
- Ointments, creams, and pastes are semisolid dosage forms intended for topical application.
- Pharmaceutical semisolids are mostly dispersions with inert, stable, compatibility with active ingredient, and patient acceptance.
Industry Scale Up
- Scale-up process of developing reliable manufacturing method for industrial production.
- Lab-scale to Kilo-scale, to pilot plant-scale, and then, to full scale production facility.
- Modern advances in modelling, digitalization, and process intensification systematize scale-up for small and large molecules.
Flow chart for cream-based and Liquid-based products
- Detailed process flows with various steps and equipment in the manufacturing line for cream-based products.
- Similar detailed process flow with various steps and equipment in the manufacturing line for liquid-based products.
Production Process Steps
- Detailed step-by-step flowchart demonstrating process steps for manufacturing (including quality control steps.)
Production Consideration: Time, Capacity & Outputs
- Information on capacity, packing sizes, and process times for various manufacturing machines.
Mixer Selection
- Factors regarding physical properties (density, viscosity, miscibility), economic factors (time & power expenditure), and equipment maintenance cost.
- Specific types of mixers based on viscosity: low, intermediate, and high.
- Mixer selection depends on product viscosity determining suitable systems for each.
Mixers/Agitators
- Employ stationary containers with moving screws, paddles, or blades to mix materials and ensure consistent mixing in the vessel.
- Specific designs for semi-solids require heavier construction for handling thick materials.
Shear Mixers
- Creation of shear forces to effectively mix materials, useful for producing emulsions and suspensions.
- Employ impellers, rotors, or inline rotors.
Sigma Blade Mixers
- Popular for mixing high viscosity materials, characterized by two contra-rotating blades and specified clearances to achieve efficient mixing.
Tangential & Overlapping Design
- Diagrams depicting tangential and overlapping mixer designs.
Planetary Mixer
- Designed with a central drive shaft, while other mixing implements rotate around it, suited for mixing viscous materials, including planetary mixing operations.
- Advantage of varying speed for dry blending and kneading action in wet granulation.
- Disadvantages include high power requirement, mechanical heat buildup in powder mix, and limitation to batch work only.
Roller Mill
- Uses rotary forms, such as colloid mills, to reduce particle size.
- Implements stators and rotors with conical working surfaces.
- Primarily used for mixing; low mixing efficiency although shear forces are good.
Colloid Mill
- Used to produce fine droplets (around 1 micron) or ensure breakdown of agglomerates; especially in emulsion production.
- High shearing and hydraulic forces create smaller droplets.
Homogeniser
- Mill particles by processing suspensions of solid particles.
- Used for particle size reduction in pharmaceutical suspensions.
