T/GDPA 1-2020 Technical specification for 3D printing drug dosage tablets in medical institutions

Scope

Main technical content: The 3D printing of hospital drug dosage involves designing a digital model on a computer, then reshaping the commercially available drug powder to precisely control the drug content of each dosage. The specific steps are as follows: According to the doctor's prescription for drug dosage, the commercially available drugs and pharmaceutical excipients are placed in a crushing device to be finely ground, and a drug paste with suitable viscosity for 3D printing is prepared. The cartridge containing the drug paste is installed on the 3D printer, and the 3D printer is started. Then, the computer operating software interface is accessed, and the model shape and related parameters are set according to the needs. The extrusion air pressure of the 3D printer is adjusted, and the printing of the dosage tablets begins. After quality checks such as appearance and tablet weight, the qualified 3D printed dosage tablets are stored in brown bottles with labels, which contain the drug name, dispensing date, specifications, etc. Pharmacists can then dispense them to patients according to the doctor's prescription.
