I. Advantages of Pharmaceutical Gelatin Hollow Capsules
High biocompatibility and safety
Natural Source: The primary ingredient is collagen derived from animal bones or hides, which is hydrolyzed to produce gelatin. It exhibits excellent compatibility with human tissues and is less likely to trigger immune reactions.
Low toxicity: Meets pharmaceutical standards (such as Chinese Pharmacopoeia, USP/NF, EP, etc.), with strict control over heavy metals, microorganisms, and other indicators to ensure medication safety.
Strong stability: It can be stored for a long time (typically 2-3 years) in dry conditions, resistant to decomposition or deterioration, ensuring drug efficacy.
Masking and Protecting Drugs
Masking unpleasant odors: It forms a coating over bitter and irritating medicinal drugs (such as antibiotics and herbal extracts), improving the patient's medication experience, particularly suitable for children or individuals with swallowing difficulties.
Isolating light and oxygen: The capsule shell can block ultraviolet rays, reduce drug oxidation and decomposition, and extend shelf life (e.g., vitamin C, easily oxidized herbal components).
Controlled release site: By utilizing enteric or gastric dissolution coating technology, the drug is released at specific locations in the intestines or stomach, enhancing efficacy and reducing side effects (e.g., aspirin enteric-coated capsules).
Process adaptability and production efficiency
Convenient filling: Compatible with automatic filling machines for efficient and precise powder or granular filling, suitable for large-scale industrial production.
Flexible dosage forms: Supports single-dose or multi-dose filling to meet diverse therapeutic needs (e.g., sustained-release capsules, divided-dose capsules).
Appearance controllable: Capsule color, size, and transparency can be customized to facilitate brand recognition and patient differentiation of medications.
The patient has excellent compliance
Easy to swallow: The smooth cylindrical surface design facilitates swallowing and minimizes the risk of throat obstruction.
Odorless and tasteless: Prevents direct contact of medication with oral mucosa, reduces taste stimulation, and enhances medication comfort.
II. Scope of Application for Pharmaceutical Gelatin Hollow Capsules
Chemical preparation
Antibiotics: such as amoxicillin capsules and cefixime capsules, to mask bitterness and protect drug stability.
Analgesic and antipyretic drugs: such as ibuprofen capsules and acetaminophen capsules, to reduce gastrointestinal irritation.
Cardiovascular medications: such as Nifedipine Sustained-Release Capsules, which achieve long-lasting blood pressure reduction through controlled-release technology.
Antacids: such as omeprazole enteric-coated capsules, which release in the intestines to avoid degradation by stomach acid.
Traditional Chinese Medicine preparation
Extract Powder: Such as Astragalus Extract Capsules and Panax Notoginseng Powder Capsules, addressing the bitterness issue of traditional Chinese medicine and improving dosage form standardization.
Compound preparations: such as Liuwei Dihuang Wan capsules, which address the difficulties in swallowing and odor issues of traditional pill formulations through encapsulation.
Health foods and nutritional supplements
Vitamins and Minerals: Such as vitamin C capsules and fish oil soft capsules, which protect easily oxidized ingredients and enhance convenience of consumption.
Probiotic preparations: such as bifidobacterium capsules, which isolate stomach acid to maintain microbial activity.
Special dosage form development
Extended-release/controlled-release capsules: Regulate drug release rate by adjusting capsule shell thickness or coating technology (e.g., theophylline extended-release capsules).
Divided-dose capsule: Designed with an openable structure for easy dosage adjustment (e.g., pediatric use).
Enteric-coated capsules: dissolve in the alkaline environment of the intestine, suitable for drugs that irritate the gastric mucosa (e.g., erythromycin enteric-coated capsules).
