1. Suitable coating materials
Choosing the appropriate coating material is the foundation for ensuring the stability of Enteric coated Hollow Capsules in the gastrointestinal tract. These materials not only need to have strong tolerance in acidic environments (such as gastric juice, pH value of about 1-3), but also need to be able to quickly dissolve in the alkaline environment of the intestine (pH value of about 6-8). The commonly used enteric coated materials in modern pharmaceutical industry, such as cellulose acetate phthalate (CAP) and acrylic resin, have been carefully designed and screened to ensure drug stability while precisely controlling their release location in the intestine. The selection of this material not only affects the effectiveness of the drug, but also directly impacts the patient's treatment experience and safety.

2. Accurate coating process
The accuracy of the coating process is crucial for the stability of enteric coated capsules. Modern pharmaceutical technologies, such as extrusion spheroidization and fluidized bed coating, ensure uniform and consistent coating thickness through highly automated equipment and precise control systems, and tightly adhere to the capsule shell. This precision not only enhances the capsule's ability to resist gastric acid erosion in the stomach, but also ensures that the drug can be released in the intestine at the expected time and speed. The optimization of coating process also involves a deep understanding of the properties of coating materials and fine adjustment of production parameters to ensure that each enteric coated capsule can achieve the best performance indicators.

3. Strict quality control
Strict quality control is a key step in ensuring the stability of enteric coated capsules. From the selection and inspection of raw materials, to every step of the production process, to the performance testing and release of finished products, strict quality standards and operating procedures must be followed. Through modern analytical techniques such as HPLC, the content and purity of drugs in capsules, as well as the stability and solubility of coating materials, can be accurately determined. These detection data not only provide scientific basis for product quality control, but also provide strong support for the optimization and improvement of production processes. At the same time, establish a comprehensive quality traceability system to ensure that every batch of products can be traced back to their raw materials and production processes, providing reliable guarantees for the safety and effectiveness of the products.

4. Reasonable storage and transportation conditions
Special attention should be paid to avoiding adverse factors such as high temperature, high humidity, and light exposure during the storage and transportation of enteric coated capsules. These factors may lead to degradation of coating materials or deactivation of drug components, thereby affecting the stability and efficacy of capsules. Therefore, corresponding storage and transportation specifications must be developed based on the characteristics of the product, and environmental conditions must be strictly controlled. For example, store enteric coated capsules in a cool, dry, and well ventilated warehouse, avoiding direct sunlight and high temperature environments; During transportation, measures such as sealed packaging and refrigerated trucks are used to ensure that the product maintains stable performance throughout the entire supply chain. In addition, regular inspections and monitoring of storage and transportation conditions are necessary to promptly identify and correct potential issues.

5. Patient medication guidance
Patient medication guidance is an important part of ensuring that enteric coated capsules have the best therapeutic effect in the patient's body. Due to the special design of enteric coated capsules, patients need to pay special attention to some things when taking them. For example, it should be avoided to take it together with acidic beverages or food to reduce damage to the capsule coating; Adequate water intake should be maintained before and after taking the medication to promote its dissolution and absorption; At the same time, it is necessary to follow the prescribed dosage and duration of medication to ensure that the drug can be released and exert its effect in the intestine as expected. Medical staff also need to explain in detail the mechanism of action, precautions, and possible side effects of enteric coated capsules to patients, so that they can use the medication correctly and provide timely feedback on medication use. Through comprehensive patient medication guidance, patients' awareness and compliance with enteric coated capsules can be improved, thereby ensuring the safety and effectiveness of the medication.
