Manufacturing Sustainability and Green Chemistry Initiatives
As environmental regulations tighten in 2026, the pharmaceutical industry is adopting "Green Chemistry" principles for the production of duloxetine API. Traditional synthesis relied heavily on chlorinated solvents and hazardous reagents like sodium hydride, which posed significant disposal challenges and occupational risks.
Modern manufacturing facilities are now implementing:
Solvent Recovery Systems: Recycling up to 90% of the organic solvents used in the synthesis process.
Enzymatic Catalysis: Exploring the use of lipases for the chiral resolution step, which can occur in aqueous conditions and eliminate the need for harsh chemical resolution agents.
Continuous Flow Manufacturing: Moving away from traditional "batch" processing toward flow reactors, which allow for better temperature control, higher yields, and reduced waste generation. These initiatives not only reduce the environmental footprint of duloxetine production but also lower long-term manufacturing costs, ensuring the continued global availability of this essential medication.
