FDA approves Orilissa ( elagolix sodium )

On July 23, 2018, Abbott's key product, elagolix, was approved by the US Food and Drug Administration, which will be used to treat the pain caused by endometriosis and become the indication for more than 10 years. Come to the first new oral medication.

Elagolix will be sold under the trade name Orilissa and will be priced at $845 per month, which is an important step for Abbott as it marks the birth of another important new product. At present, Abbevi's heavy products, worth $16 billion in immunization drugs Humira will be affected by the competition of biosimilars, starting with Europe at the end of this year and new competition in the United States by 2023.

Elagolix will be available in the US early next month and is expected to grow rapidly to $1 billion in annual sales, and if the regulator approves other indications such as uterine fibroids, it will quickly exceed this figure.
