hi everyone,

I am trying to analyze risedronate from tablets which is contain Calcium and Vit. D3. Risedronate, as bisphosphonate chealating with metals, so I could not find proper solvents to extract only risedronate from tablets and also I use EDTA for chealating agent to eliminate Ca from sample.

I am looking for your advise,

Thank you,
sehvar
