1.Material properties
HPMC capsules:
HPMC capsules are distinguished by their pure plant origin, which makes them particularly popular among vegetarians and consumers with specific dietary beliefs. Its low moisture and high toughness properties make HPMC capsules particularly suitable for filling traditional Chinese medicines, which generally require a more stable and durable capsule shell. In addition, HPMC, as an inert material, does not contain amino acids, which avoids possible cross-linking reactions between the drug and the capsule and ensures the effectiveness and safety of the drug. In addition, the main models of HPMC capsules include 00#, 0#, and 1#, providing flexible choices for drugs of different specifications and dosage forms.
Other biodegradable materials (taking PLA as an example):
PLA (polylactic acid), as a biodegradable material, also has significant advantages in the field of drug delivery. First of all, its degradability is mainly based on the physical and biochemical effects of microorganisms and the direct action of enzymes, which means that after drug use, PLA capsules can naturally degrade and reduce environmental pollution. Secondly, PLA is relatively convenient to store and transport. It only needs to be kept dry and no special storage conditions are required.

2. Drug delivery efficiency
HPMC capsules:
HPMC capsules excel in drug delivery efficiency. Its good film-forming properties, uniformity and light transmittance contribute to the uniform distribution and rapid release of drugs within the capsule. At the same time, due to its pure plant origin and low moisture characteristics, HPMC capsules can maintain the stability and effectiveness of the drug, ensuring the activity and effect of the drug during delivery.
Other biodegradable materials:
Biodegradable materials such as PLA also have significant advantages in drug delivery. They can serve as drug carriers to improve drug delivery efficiency by improving drug solubility and stability. In addition, by adjusting the particle size and composition of nanomaterials, biodegradable materials can achieve slow and sustained release of drugs, thereby improving drug efficacy and mitigating possible side effects.

3. Environmental friendliness
HPMC capsules:
HPMC capsules excel in environmental friendliness due to their green and safe characteristics. As a purely plant-derived material, HPMC capsules will not cause pollution to the environment during production and use. At the same time, its low moisture and high toughness properties make HPMC capsules less likely to break or leak during use, further reducing the risk of environmental pollution.
Other biodegradable materials:
Biodegradable materials such as PLA also have significant advantages in environmental friendliness. They can naturally degrade under the action of microorganisms and reduce environmental pollution caused by plastic waste. In addition, biodegradable materials can also be turned into compost and returned to nature, providing nutrients for the environment. This environmental friendliness makes biodegradable materials ideal for drug delivery.

4. Cost and feasibility
HPMC capsules:
HPMC capsules are relatively high in cost, mainly due to their pure plant origin and special production process. However, with the advancement of technology and the expansion of production scale, the cost of HPMC capsules is expected to gradually decrease. In terms of feasibility, the dissolution performance of HPMC capsules has not been significantly improved, which limits its promotion in certain pharmaceutical product fields. However, with the deepening of research and technological innovation, the dissolution performance of HPMC capsules is expected to be improved, thereby increasing its competitiveness in the field of drug delivery.
Other biodegradable materials:
Biodegradable materials also have certain advantages in terms of cost and feasibility. Although their production costs may vary depending on production scale and technology level, the cost of biodegradable materials remains competitive with traditional plastic materials. In addition, the widespread use of biodegradable materials in the medical industry has also proven their feasibility and effectiveness in practical applications. However, in order to further promote the application of biodegradable materials in the field of drug delivery, some technical difficulties and marketing issues still need to be solved.

HPMC Hollow Capsules

Product introduction: The main raw material of hydroxypropyl methylcellulose hollow capsule is HPMC, which is extracted from natural cotton or wood pulp, which can effectively prevent foot-and-mouth disease.
Product Category: Pharmaceutical Excipients
Product application: HPMC has no side effects on the human body, and provides a new choice for vegetarians and people of different religious beliefs.
Product function: The drying weight loss of HPMC capsules is controlled within 6%, and the molecular structure is stable, and the moisture requirements of the filling are low. When filling drugs with strong hygroscopicity, the capsules will not be ruptured. It does not affect the moisture of the filler, making the filler safer and more thorough in dissolution.
