Soft Gelatin Capsules: A Complete Guide for Beginners
Soft gelatin capsules are a popular dosage form in the pharmaceutical and nutraceutical industries. They are easy to swallow, tasteless, and can be filled with a variety of liquids, suspensions, and powders. In this blog post, we will guide you through the manufacturing process of soft gelatin capsules and answer some frequently asked questions.
What are Soft Gelatin Capsules?
Soft gelatin capsules are a type of oral dosage form that consists of a gelatin shell filled with a liquid, suspension, or powder. The gelatin shell is flexible and easy to swallow, and it dissolves quickly in the stomach, releasing the active ingredient.
Soft gelatin capsules are used to deliver a wide range of drugs, vitamins, and supplements, including oils, suspensions, and powders. They are also used to mask unpleasant tastes and odors and to protect the active ingredient from oxidation, moisture, and other environmental factors.
How are Soft Gelatin Capsules Manufactured?
Soft gelatin capsules are manufactured through a process called encapsulation. The process involves four main steps: gelatin melting, filling, sealing, and drying.
Gelatin Melting: The first step in the manufacturing process is to melt the gelatin in a hot water bath. Gelatin is a protein derived from collagen, which is extracted from animal bones and skin. The gelatin is heated to a temperature that liquefies it, and any impurities or air bubbles are removed.
Filling: Once the gelatin is melted, the liquid, suspension, or powder is added to the gelatin solution. The mixture is stirred to ensure uniform distribution of the active ingredient, and any air bubbles are removed. The filling process can be done manually or using a filling machine.
Sealing: After the filling process is complete, the two halves of the gelatin shell are sealed together using heat or ultrasonic welding. The sealing process creates a hermetic seal that prevents leakage or contamination of the active ingredient.
Drying: The final step in the manufacturing process is to dry the soft gelatin capsules. The capsules are placed in a drying chamber, where they are exposed to a warm, dry environment. The drying process removes any remaining moisture from the gelatin shell and ensures that the active ingredient is stable.
