Chugai's Edirol Tablet approved in Japan as osteoporosis therapy

16 August 2022

Japanese pharma major Chugai Pharmaceutical (TYO: 4519) has obtained regulatory approval from the Ministry of Health, Labor and Welfare (MHLW) for the osteoporosis treatment Edirol (eldecalcitol) Tablet (0.5µg/0.75µg).

Edirol is an active vitamin D3 derivative created based on Chugai’s long-standing vitamin D research. The drug was launched in 2011 in a soft capsule formulation as Edirol Capsule, and has been used as a base drug for the treatment of osteoporosis. Due to the characteristics of the formulation, Edirol Capsule rolls easily and is hard to grasp with fingers. In addition, patients using Edirol often take other drugs, too. Considering these points, Chugai developed an alternative tablet formulation for Edirol that is easier to handle and identify. The regulatory approval for Edirol Tablet is based on the results of a bioequivalence study comparing the soft capsule and the tablet in 49 healthy adult volunteers.
