Common Types of Gelatin Capsules
Gelatin capsules are widely used in the pharmaceutical and nutraceutical industries for encapsulating various drugs, supplements, and other substances. Here are some common types and variations:
1. Hard Gelatin Capsules (HGC):
These widely used capsules undergo stringent hardness tests to ensure they maintain structural integrity. They are composed of gelatin, water, and a plasticizer like glycerin or sorbitol. Available in various sizes, typically ranging from 000 (largest) to 5 (smallest), they are subjected to rupture tests to verify their resistance to breaking under pressure. They can also be colored and printed for branding and identification purposes.
2. Soft Gelatin Capsules (SGC):
Soft gelatin capsules, subjected to both hardness and rupture tests, offer a flexible shell that’s easy to swallow. Comprising a gelatin shell containing a plasticizer, water, and a gelling agent like glycerin or sorbitol, they’re commonly used for liquid or oily substances. These capsules ensure durability while providing a convenient way to encapsulate substances.
3. Enteric-coated Gelatin Capsules:
Featuring a special coating, these capsules undergo rigorous hardness and rupture tests to ensure they withstand acidic conditions in the stomach. Instead, they dissolve in the alkaline environment of the small intestine, safeguarding sensitive drugs from stomach acid. Their robust construction ensures reliable performance and targeted drug delivery.
4. Vegetarian Capsules:
Made from plant-based materials, such as cellulose, these capsules offer an alternative to gelatin capsules. Subjected to hardness and rupture tests, they meet the same quality standards while accommodating vegetarian and vegan preferences. Available in both hard and soft varieties, they provide versatility without compromising on performance.
5. Flavored Capsules:
Capsules can undergo hardness and rupture tests even after being flavored, ensuring they maintain structural integrity while masking taste or odor. Common flavors include mint, vanilla, and fruit, enhancing palatability without compromising on quality. These capsules provide a pleasant experience for patients while delivering the desired medication.
6. Sustained-release Capsules:
These capsules, subjected to hardness and rupture tests, are designed to release their contents gradually over time. Whether for medications needing less frequent dosing or those requiring steady release, they undergo rigorous testing to ensure consistent performance. Their robust construction and controlled release mechanism provide reliable and effective drug delivery.
7. Empty Gelatin Capsules:
These capsules, often filled with custom formulations, undergo hardness and rupture tests to verify their suitability for encapsulation. Used by compounding pharmacies and individuals alike, they offer flexibility and convenience while meeting rigorous quality standards. Their robust construction ensures reliable containment of various substances.
8. Colored and Printed Capsules:
Gelatin capsules, subjected to hardness and rupture tests, can be colored and printed with logos, brand names, or dosage information for easy identification. These capsules undergo stringent quality control measures to prevent mix-ups and ensure the correct medication is taken. Their durable construction and customizable design make them a preferred choice for pharmaceutical and nutraceutical applications.
