The Manufacturing Process of Soft Gelatin Capsules: A Comprehensive Guide
Soft gelatin capsules are widely used in the pharmaceutical and nutraceutical industries for encapsulating liquids, suspensions, or semisolids. They offer numerous advantages such as easy swallowing, precise dosage, and better stability. This blog post will delve into the manufacturing process of soft gelatin capsules, providing a detailed overview for the audience in Vadodara.
I. Understanding Soft Gelatin Capsules
Soft gelatin capsules consist of a gelatin shell that encapsulates the active ingredient(s) in a liquid or semisolid form. The capsules are flexible and hermetically sealed to ensure product integrity and longevity.
II. Manufacturing Process of Soft Gelatin Capsules
Formulation Development:
Determine the active ingredient and excipients.
Select the appropriate gelatin type (animal or vegetable origin).
Optimize the composition for stability, release, and bioavailability.
Gelatin Preparation:
Gelatin is extracted from animal bones or vegetable sources.
It is processed to remove impurities and obtain the desired gelatin concentration.
The gelatin solution is sterilized and cooled before use.
Encapsulation:
The encapsulation process involves two gelatin ribbons.
One ribbon is formed into a continuous strip of individual capsule-shaped pockets.
The pockets are filled with the active ingredient formulation.
The second ribbon is placed on top, and the two ribbons are sealed together.
Drying and Inspection:
The capsules undergo a drying process to remove excess moisture.
Drying may occur in a tray dryer or a rotating tumbler dryer.
After drying, the capsules are visually inspected and tested for quality control.
Printing and Packaging:
Capsules can be printed with logos, brand names, or dosage information.
Packaging includes blister packs, bottles, or bulk containers.
Proper labeling and storage conditions are essential to maintain capsule integrity.
