| Title: | PROCESS FOR PREPARATION OF HIGH-PURITY MELOXICAM AND MELOXICAM POTASSIUM SALT | ||||||||||||||||||
| Abstract: | The invention provides a process for the preparation of high purity meloxicam of the Formula (II). The meloxicam raw product is reacted with the solution of potassium hydroxide or potassium carbonate, whereby high purity meloxicam potassium sait monohydrate is produced. Said sait is subsequently treated with minerai or organic acid to yield high-purity meloxicam. | ||||||||||||||||||
