Drug Storage Overview

Drug storage refers to the storage and management of drugs through scientific methods to ensure their quality, safety and effectiveness. The main contents include storage environment (temperature and humidity, lighting, ventilation), classified storage (prescription drugs, non-prescription drugs, special drugs), packaging requirements and expiration date management. The focus is on preventing the deterioration, confusion or misuse of medicines. The secondary content involves storage skills of household medicines and management practices of medicine warehouses in medical institutions.

Environmental requirements for drug storage

Drug storage requires strict control of environmental conditions. In terms of temperature, most medicines need to be stored in a cool place below 20°C, and some need to be refrigerated (such as insulin and biological agents); the humidity should be controlled between 45% and 75% to avoid getting damp. Light-sensitive drugs (such as nitroglycerin) need to be stored away from light and packaged in brown bottles or aluminum foil. In addition, medicines should be kept away from sources of contamination (e.g., chemicals, pets) and kept well ventilated. For example,AspirinIt is prone to hydrolysis and failure in humid environments and needs to be sealed to prevent moisture.

Classified storage and identification management

Drugs must be stored according to their nature: oral drugs and external drugs should be separated to avoid accidental ingestion; narcotic drugs and psychotropic drugs must be locked in special counters. The original packaging label should be complete and clear, and the name and expiration date of the disassembled medicine should be marked. Medical institutions need to adopt"First in, first out"In principle, drugs with the closest expiration date should be used first. It is recommended to use divided medicine boxes for home medicine storage, and children's medicines should be placed at high places. Such asibuprofen suspensionAfter opening, it needs to be refrigerated and marked with the opening date. Use it within 1 month.

Validity period and exception handling

Regularly check the validity period of medicines. Expired medicines must be disposed of as medical waste (cannot be discarded at will). If you find that the medicine is discolored (such as vitamin C tablets turning yellow), agglomerated (such as isatis granules) or has an odor, stop using it immediately. Special drugs such asNitroglycerinIt expires 3 months after opening and needs to be replaced in time. Medical institutions need to establish early warning systems for drugs with near-expiration dates, and families can use mobile APPs to set reminders.

Summary and Notes

Drug storage is a key link to ensure drug safety and requires comprehensive environmental control, classification management and validity period monitoring. The amount of medicine stored at home should not be too large to avoid waste; medical institutions need to train personnel regularly. Common mistakes include freezing medicines in the refrigerator (for example, insulin cannot be frozen) and mixing internal and external containers.
