Particle size control is essential for achieving reliable drug performance and maintaining manufacturing consistency in pharmaceuticals. The particle size control of pharmaceutical powders plays a crucial role in ensuring the consistent quality of solid oral dosage forms.
The particle size control of the drug substance significantly impacts the final drug product’s performance. It affects dissolution, solubility, bioavailability, content uniformity, stability, and even product appearance. For instance, uniform API size distribution ensures predictable drug release, enhancing absorption and efficacy.
Both drug substances and excipients’ particle size control influence drug product manufacturability. Proper flowability, blend uniformity, and compactibility depend on particle sizes. Maintaining proper particle size control during manufacturing processes (mixing, granulation, etc.) ensures consistent quality.
How do high shear mixers work?
High-shear mixers are specialised devices used in industrial processes to achieve intense mixing, dispersion, and particle size reduction. They play a critical role in achieving consistent quality across various industries!
High-shear mixing involves using shear forces to emulsify, homogenise, disperse, or reduce particle size in a mixture. Shear force occurs when different parts of the mixture move in opposite directions simultaneously. The result is thorough mixing and particle size reduction, aiding in homogenization.
High-shear mixers consist of two key components: a moving rotor and a stationary stator. Materials are introduced into a narrow gap between these components. As the rotor rotates, it creates intense shear forces, subjecting the materials to stress and ensuring thorough mixing. High-speed dispersion blades can also achieve high shear blending by forcefully dispersing materials into smaller particles.
Types of high shear mixers and their usage
There are usually two types of
high shear mixers:
- Batch mixers
- In-Line mixers
Batch mixers blend a set amount of ingredients in a single vessel for a specified amount of time. They are ideal for small-scale operations or customised batches.
On the other hand, in-line mixers continuously blend materials as they pass through the mixer. They are more suitable for consistent production but have less control over ingredients.
Why are shear mixers important in pharmaceutical settings?
High shear mixers play a crucial role in pharmaceutical applications by tackling key manufacturing challenges. They are essential for ensuring quality, optimal drug performance, and efficient pharmaceutical production.
In the pharmaceutical industry, mixing ingredients with excipients is common. High shear mixers help ensure the distribution of APIs within the matrix, improving content uniformity and drug effectiveness.
Maintaining particle size is vital for drug dissolution and bioavailability.
High shear mixers work to break down particles, resulting in an even distribution and predictable drug release.
For formulations like creams, ointments, and suspensions that require emulsions, high shear mixers are indispensable. By breaking down oil droplets, they create emulsions that contribute to product stability.
Formulations like creams, ointments, and suspensions require stable emulsions. High shear mixers create fine emulsions by breaking down oil droplets, ensuring product stability.
Granules are intermediate products used in tablet manufacturing. High shear mixers facilitate wet granulation, improving flow properties and compressibility.
High shear mixers reduce processing time compared to traditional methods. Faster production cycles enhance efficiency and reduce costs.
