BroucherManufacturing process of Lubiprostone
Before beginning the process operation, check the cleanliness of equipment, confirm the availability of utilities, and verify that all raw materials and packing materials are available.
Charge dichloromethane in glass pot and the starting materials and reagents, including prostaglandin derivatives, are charged. Heat the reaction mass up to 50–60°C and maintain the reaction mass at 50–60°C for 240–360 minutes, Take the in-process sample from reaction mass and send the in-process sample to QC for reaction monitoring by HPLC.
The product is purified using a chromatographic column or liquid-liquid extraction. Crystallization is initiated by cooling the purified solution to 0–5°C and adding an anti-solvent. The product is then filtered and washed with chilled solvent to remove residual impurities. Drying is performed under vacuum at 40–50°C for 480–600 minutes.
Pack Lubiprostone in a glass or polypropylene vial. Place the vial inside a poly bag, twist its mouth, and secure it with a PVC strip. Insert this bag into a triple-laminated aluminum bag and seal it properly. Finally, place the sealed aluminum bag in an HDPE container. Store Lubiprostone in a tightly closed, light-resistant container at a temperature of 20°C to 25°C.
