What other active ingredients are in apotex's ruxolitinib formulation?

Short answer: no. Apotex’s ruxolitinib product is a single-ingredient formulation. The only active ingredient is ruxolitinib (usually listed as ruxolitinib phosphate, the salt form used for oral tablets). Any other ingredients are inactive excipients, which can vary by strength and lot.

If you want the exact list of inactive ingredients for a specific strength and country, I can look up the product label for you. Tell me the country (e.g., US, Canada) and the tablet strength (e.g., 5 mg, 10 mg), and I’ll pull the label.
