The role of checkweighers in capsule checkweighing

2024-09-03

When discussing the widely used drug forms in the modern medical system, we have to mention a unique existence - capsules. These micro-containers, usually in the form of cylindrical shells, carefully encapsulate powdered or liquid drugs inside. They have won wide recognition and application for their portability, precise dosage control, excellent drug stability, and advanced characteristics of timely release of drug effects. However, as a drug form directly related to the health and safety of patients, every detail of the capsule is crucial.

Dosage, the core element of drug properties, is particularly important in the manufacture and use of capsules. Insufficient drugs may not achieve the expected therapeutic effect, while excessive intake may cause adverse reactions, directly endangering the health and even life of patients. Therefore, ensuring the accuracy of the dosage of each capsule is an unshirkable responsibility and mission of the pharmaceutical industry.

In order to achieve this goal, the pharmaceutical industry has introduced the capsule weight detection link, which aims to verify whether each capsule meets the established quality standards through scientific methods. However, due to the tiny size, light weight and large production volume of the capsule itself, this detection process faces huge challenges. Although the traditional sampling method can reflect the overall quality level of the product to a certain extent, its limitations are obvious. It is difficult to fully cover every capsule, leaving potential quality risks.

Specifically, the weight range of the capsule after filling is usually between 150 mg and 1500 mg, which belongs to the category of small weight. Considering the huge scale of capsule production, the number of capsules that can be produced per hour is often hundreds of thousands, which undoubtedly puts extremely high demands on the performance of the weight inspection equipment. Therefore, the production of equipment that can accurately and efficiently check the weight of capsules is not only technically difficult, but also has a high threshold, resulting in a limited number of suppliers of related products on the market.

Nevertheless, for drug production and management, achieving 100% capsule-by-capsule weight inspection is still an indispensable link. It is not only an important measure to ensure the quality and safety of drugs, but also the key to enhancing patient trust and promoting the healthy development of the pharmaceutical industry. To this end, we need to actively learn from international advanced experience, and at the same time encourage domestic strong enterprises to increase R&D investment, improve or develop more advanced and reliable capsule weight inspection equipment, and contribute to the quality improvement of domestic drugs.
