Process for the preparation of acebrophylline |
| abstract |
The present invention relates to an improved process for preparing Acebrophylline comprising preparing a reaction mixture of theophylline-7-acetate and ambroxol base in a non-polar solvent; heating said reaction mixture at a suitable temperature; and isolating Acebrophylline by filtration. The yield of Acebrophylline is between 95-98% with a purity of 99%. |
