How Vanguard tests Meloxicam

Method for the $250 identity, purity and quantity test: HPLC-UV purity and assay, LC-MS identity, against a reference standard, with results in 3 to 5 business days.

The USP monograph covers identity by infrared spectroscopy and HPLC retention time, assay by HPLC, organic impurities by two HPLC procedures, and residue on ignition and loss on drying. Full testing to the USP Meloxicam monograph is available and quoted.

What's reported

Purity, as percent of total peak area

Questions about Meloxicam testing

Is the $250 test the same as USP monograph testing?

No. The $250 test covers identity, purity and quantity by HPLC-UV for purity and assay, with LC-MS to confirm identity. Full testing to the USP Meloxicam monograph is available and quoted.

What does meloxicam powder normally look like?

Meloxicam is a pale yellow powder. A clearly different color can point to degradation or a mislabeled material, which the HPLC purity and LC-MS identity results then confirm.

Can meloxicam suspensions and tablets be tested?

Yes. Oral suspensions, tablets and powders can all be tested; the sample is extracted and the meloxicam content is reported for the form submitted.
