Zusammenfassung: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 salt monohydrate is produced. Said salt is subsequently treated with mineral or organic acid to yield high-purity meloxicam.
