Title:
DRUG COMPRISING LANTHANUM CARBONATE HYDRATE HAVING ADJUSTED PARTICLE SIZE
Document Type and Number:
WIPO Patent Application WO/2016/051609
Kind Code:
A1
Abstract:
This drug comprises a lanthanum carbonate hydrate which has a 90% cumulative diameter (D90) of 70μm or less and which is represented by La2(CO3)3⋅xH2O (in the formula, x represents a number 7-9). The drug does not have the problem of decreased product quality due to heat and moisture, and moreover allows quick and reliable removal of phosphates.
