The preparation needs to "mix" the raw material in some excipients or solvents to reach the desired concentration, and finally can be provided to the drug target for use. Different forms of preparation solve the problem of drug usage and dosage, but also put forward higher requirements for safety.  In order to keep the product uniform and stable, the active ingredients meet the requirements of drug use, and control the potential risks, the process needs to be equipped with precise filtration solutions to ensure the product compliance and safety, in accordance with GMP requirements .

The use of modern pharmaceutical technology, the drug will be dispersed in the special structure of the system, so as to change the pharmacokinetic characteristics and tissue distribution of the drug in the body, to improve the efficacy of the effect. This requires uniform filter aperture size, strong interception ability, no particle leakage; No media migration, does not affect the PH of the pharmaceutical industry; Small adsorption, fast filtration speed, does not affect the content of the main drug.
