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.
- 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 by heat, radiation, or filtration.
- Aseptic Processing: Manufacturing processes are conducted under sterile conditions to prevent contamination.
- Quality Control: Regular monitoring and testing ensure sterility and safety throughout the process
In-Process Quality Checks

- Quality Auditing: Regular audits ensure compliance with regulations and internal quality standards.
Pharmaceutical Semisolids
- Ointments, creams, and pastes are semisolids used for topical application.
- Semisolids are mostly dispersions: inert, compatible with active ingredients, stable, and patient-acceptable.
- Most semisolids treat dermatological issues, applied to mucous membranes (rectal, buccal, vaginal, rectal mucosa, external ear lining, nasal mucosa, and cornea).
Type of Semisolids
- Different types include cream (oil-in-water, water-in-oil), paste, ointment, and gel with various liquid/solid phases.
- Specific examples of different semisolids (e.g., aqueous cream BP, oily cream BP, zinc and salicylic paste) are discussed.
Industrial Scale-Up
- Large-scale production methods, from lab-scale studies (0.5kg) progress through various stages (pilot scale, plant-scale, full scale).
- Modern engineering and scale-up methods streamline this process.
Production Process Steps: Flow Charts
- Detailed flow charts are provided for cream-based and liquid-based products, illustrating the manufacturing process steps.
Production Process Steps (additional)
- The presentation includes process flowcharts for the production of both cream-based and liquid-based products. Flowcharts illustrate the specific steps from raw materials to final products.
Cases of Failures in Pharma Manufacturing
- Product contamination, process defects, production mistakes, and mislabeling are common issues.
- These failures can compromise patient safety.
- Mitigating steps include product recalls.
Industrial Processing
- Industrial processes involve mixing, the primary components of the various machines (e.g., impellers of propellers, turbines, or paddles, helical ribbons, Z-blades).
- Blade configuration and placement influences mixer performance.
Objectives of Mixing
- Uniformity of composition is achieved by sampling, physical and chemical reactions (e.g., diffusion, dissolution) are initiated or enhanced through mixing.
- Several common problems (e.g., segregation, overmixing) and their impacts are discussed.
Mixtures
- Miscible liquids form solutions, while immiscible liquids forming emulsions in presence of binding agents..
- Solids dissolved in liquids create solutions, while insoluble solids in a liquid form suspensions.
- Different types of mixtures are described: positive (homogeneous mixing) and negative (heterogeneous).
Mixing Mechanisms
- Convective mixing, shear mixing, and diffusion are the key mixing mechanisms.
Mixer Selection
- Factors considered while selecting a mixer include physical properties of the material, economic considerations (operation timing, power expenditure), and cost & upkeep.
Semisolids Mixer Selection
- Based on the viscosity of the semisolids (which are low, intermediate, or high), different mixing systems are selected
Mixer: Low Viscosity System
- Systems are highly efficient at creating turbulence and circulating material.
- High-velocity jets are suitable for materials with low viscosities, and high-speed impellers.
Mixer: Intermediate Viscosity Systems
- These systems are used for immiscible liquids (emulsions) and finely divided solids in low-viscosity liquids (suspensions).
- Mixing is achieved via turbines with flat blades.
Mixer: High Viscosity Systems
- Systems utilize shearing actions between surfaces for mixing highly viscous products like ointments.
Mixers/Agitators
- Mixers employ stationary containers with mixing tools (e.g., screws, paddles, blades).
- Components must be suitable for the specific consistency of the mixing materials to maximize outcome.
Shear Mixers
- Shear mixers use impellers, high-speed rotors, or inline rotors to mix substances, causing relative velocity differences in adjacent parts of the fluid. This creates fluid and shear. Commonly used machines in this process include roller mills and homogenizers.
Sigma Blade Mixers
- Sigma blade mixers are a common type of high-speed mixer. Their design ensures a uniform mixing process with minimal dead space.
