Takeda is weighing the sale of Shire's Xiidra drug which treats dry eye, as well as its Natpara medicine used to control low blood calcium levels, the report said https://www.bloomberg.com/news/articles/2018-09-13/takeda-is-said-to-weigh-sale-of-shire-eye-care-drug-to-cut-debt, citing people familiar with the matter.

The sale could help Takeda raise between $4 billion and $5 billion, Bloomberg reported.

Takeda agreed to buy Shire in May, in what would be the largest overseas purchase by a Japanese company.

Neither Takeda nor Shire immediately responded to Reuters' requests for comment.
