Manufacturing process of Hydrochlorothiazide
The manufacturing process begins with ensuring equipment cleanliness and availability of utilities, raw materials, and packing materials.
Charge water or ethanol is into the Glass line reactor (GLR) and add intermediate compounds and reagents. Stir the reaction mass for 10-15 min. and heat the reaction mass up to 80–90°C and maintain the reaction mass temperature 80–90°C for 240–360 minutes. Take the in-process sample from reactor and send the in-process sample to Quality control (QC) for reaction monitoring by HPLC.
After in-process result complies, cool the reaction mass up to 20–25°C, and an anti-solvent is added to crystallize the product. The product is filtered and washed with chilled solvent to remove impurities.
Drying is conducted in a vacuum dryer at 50–60°C for 480–600 minutes. The dried material is milled and sieved to ensure uniform particle size.
Pack Hydrochlorothiazide in a clear poly bag and twist the mouth of the bag. Secure it with a PVC strip. Place this bag inside another poly bag, twist its mouth, and secure it with a PVC strip. Insert these bags into a triple-laminated aluminum bag and seal it properly. Finally, place the sealed aluminum bag in an HDPE container. Store Hydrochlorothiazide in a tightly closed, light-resistant container at a temperature of 20°C to 25°C.
