1. Chemical stability of HPMC capsules
The chemical stability of HPMC capsules is mainly due to its molecular structure and physical properties. This material is a non-ionic polymer composed of hydroxypropyl and methyl substituted cellulose, has good chemical inertness, and is not easy to react with drug ingredients.

Acid and alkali resistance
HPMC capsules have good stability in a wide pH range and can tolerate acidic and alkaline environments. This feature is particularly suitable for gastrointestinal drug release to ensure that the drug does not degrade when passing through the digestive tract.

Antioxidant properties
Oxidation is one of the important factors in drug degradation, especially for sensitive ingredients such as polyunsaturated fatty acids and certain vitamins. HPMC capsules can effectively block the intrusion of oxygen and reduce the oxidation reaction of drugs, thereby protecting the active ingredients of drugs and extending the shelf life. Compared with traditional gelatin capsules, HPMC capsules have more significant antioxidant properties, which helps to improve the stability of drugs.

Water resistance
HPMC capsules have water resistance and are not easy to absorb moisture. This feature is crucial for many hygroscopic drugs. In a humid environment, traditional capsules may absorb moisture and cause deformation or dissolution, thus affecting the release characteristics and dosage accuracy of the drug. HPMC capsules can effectively prevent moisture penetration, keep the drug dry, and ensure the quality and effectiveness of the drug.

2. Advantages of HPMC capsules in drug packaging
Thanks to its chemical stability, HPMC capsules have shown many application advantages in the field of drug packaging.

Improve drug stability
By using HPMC capsules, pharmaceutical companies can effectively improve the chemical stability of drugs and reduce the risk of drug degradation during storage and transportation. This advantage is particularly suitable for biological preparations and new drugs with high requirements for chemical stability, and can provide patients with safer and more effective treatment options.

Reduce side effects
Chemically unstable drugs may decompose in the body to produce harmful substances, leading to increased side effects. The chemical inertness of HPMC capsules can effectively avoid such problems, ensure the safety of drugs in the body, and thus improve the patient's medication experience.

Suitable for complex formulations
The chemical stability of HPMC capsules makes it suitable for a variety of complex drug formulations, including those containing compound preparations with active ingredient interactions. This allows pharmaceutical companies to explore more innovative drug combinations and improve therapeutic effects.

Facilitating personalized drug development
With the rise of personalized medicine, HPMC capsules can be customized according to the specific needs of patients.
