In the pharmaceutical field, the clean room is just like a precise "fortress for drug production", safeguarding every step of the process from raw material processing to finished product output. And temperature and humidity are the invisible yet crucial "invisible guardians" in this fortress.

The quality of drugs is the lifeline of pharmaceutical enterprises. Even the slightest fluctuation in temperature and humidity can put this lifeline at risk. Take solid tablets for example. The moisture content has a profound impact on key indicators such as the disintegration time limit and hardness. If the humidity in the workshop is too high, the tablets will absorb excessive moisture, which may delay disintegration and affect the release rate of the drug in the body, thus greatly reducing the efficacy. On the contrary, if it is too dry, the tablets will crack and their integrity will be damaged, which also fails to meet the quality standards. For liquid preparations such as injections and biological products, out-of-control temperature is even more "fatal". High temperature promotes the rapid proliferation of microorganisms and accelerates the degradation of the active ingredients of drugs. For insulin drugs that require a cold chain, once the temperature in the workshop exceeds the appropriate range, the risk of deterioration will soar. After injection, instead of lowering blood sugar, it may cause serious adverse reactions and endanger the life and health of patients.

The production process of pharmaceuticals is complex and precise, and each step has its own "exclusive requirements" for temperature and humidity. During the synthesis stage of sterile APIs, many chemical reactions rely highly on precise temperature and humidity. For example, in the fermentation of certain antibiotics, the appropriate temperature is the "hotbed" for microorganisms to efficiently produce the target products. Precise regulation of humidity can prevent miscellaneous bacteria from "taking advantage of the situation", ensuring the production of high-purity APIs. In the preparation process of soft capsules, including the preparation of glue solution, the formation of soft capsules, and drying and solidification, the temperature and humidity in each step are closely connected. If the temperature is not suitable, the viscosity of the glue solution will be abnormal, and the thickness of the soft capsule shell will be uneven. If the humidity is out of balance, the capsules will deform due to too fast drying or get moldy due to too slow drying. The whole process is "thrilling" at every step. Only when the temperature and humidity strictly comply with the specifications can the production proceed in an orderly manner.

There are various high-precision pharmaceutical equipments standing in the clean room. They are the "powerful tools" for mass production of drugs, while temperature and humidity are the "maintenance agents". Electronic pharmaceutical equipments are afraid of moisture. After getting damp, short circuits in circuits and corrosion and damage of components occur frequently. If a high-performance liquid chromatograph worth millions of yuan breaks down and stops working, the production line will be suspended, and the losses will be immeasurable. If the temperature is too high, the equipment will have poor heat dissipation, and the mechanical parts will expand and contract due to heat, resulting in inaccurate transmission precision. The pressure of the tablet press will be uneven, and the dosage of the capsule filling machine will deviate. If it continues to "work with problems", the defective product rate will soar, and the enterprise will bear both the maintenance cost and the hidden quality risks.

The front-line operators in the workshop are the "main force" of pharmaceutical production. A comfortable temperature and humidity environment is the prerequisite for efficient work. In summer, when it is hot and stuffy, workers are prone to heatstroke, fatigue, and distraction, which will increase the number of operational errors and the risks of quality accidents such as drug confusion and incorrect labeling. In winter, when it is bitterly cold, the flexibility of hands will be limited, making it more difficult to perform delicate operations. Moreover, uncomfortable temperature and humidity are conducive to the reproduction of bacteria and viruses, increasing the probability of cross-infection among workers. During the flu season, it may cause many workers in the workshop to "fall ill", delaying the production progress. This is related to the timeliness of drug supply, and a single change can affect the whole situation.

The control of temperature and humidity in pharmaceutical clean rooms is by no means a trivial matter. It is a core element that runs through multiple dimensions such as drug quality, production, equipment, and personnel. Pharmaceutical enterprises need to rely on professional temperature and humidity monitoring systems to "keep a close eye on everything", and rely on precision air conditioners, dehumidifiers, and humidifiers to accurately "adjust as needed", strictly adhere to the "safe zone" of temperature and humidity, and build a solid foundation for the quality of pharmaceuticals, so as to provide reassuring and high-quality drugs for safeguarding public health.
