Liquid Fill Caps

Liquid-filled capsules, are a dosage form that involves encapsulating liquid formulations within a gelatin or vegetarian capsule shell. These capsules provide an alternative to traditional solid dosage forms such as tablets or hard capsules filled with dry powders. Liquid-filled capsules are commonly used in the pharmaceutical and nutraceutical industries for delivering liquid formulations of drugs, supplements, or other active ingredients.

​

Here are some key features and considerations regarding liquid-filled capsules:

​

1. Encapsulation of Liquid Formulations: Liquid-filled capsules are designed to contain liquid formulations, which may include oils, suspensions, solutions, or other liquid substances. This can be advantageous for substances that are not easily formulated as dry powders.

2. Gelatin or Vegetarian Shell: The outer shell of liquid-filled capsules can be made from either gelatin or vegetarian alternatives such as hydroxypropyl methylcellulose (HPMC) for those seeking a vegetarian or vegan option.

3. Improved Bioavailability: In some cases, liquid formulations may offer better bioavailability compared to dry forms, as they can be absorbed more quickly in the gastrointestinal tract.

4. Reduced Disintegration Time: Liquid-filled capsules may disintegrate faster in the stomach compared to solid capsules, facilitating the release of the liquid content.

5. Protection of Sensitive Compounds: Liquid-filled capsules can provide a protective barrier for sensitive or unstable compounds, shielding them from external factors such as moisture and oxidation.

6. Taste Masking: For formulations with unpleasant tastes or odors, liquid-filled capsules can help mask these attributes, improving patient acceptability.

7. Ease of Swallowing: Liquid-filled capsules may be easier for some individuals to swallow compared to large tablets or solid capsules, making them a more patient-friendly dosage form.
