Commenting on the development, Cipla USA and Canada CEO Timothy Crew said: "We are delighted to be partnering with Salix Pharmaceuticals and to expand on our existing license to Salix to introduce rights to the 'Rifaximin Complexes' patent applications."
Salix is required to make an up-front payment and, upon achievement, additional regulatory milestone payments to Cipla in respect of the new license agreement, Cipla said without sharing details.
"Salix also will pay a royalty on net sales of products covered by the 'Rifaximin Complexes' patents licensed to Salix," it added.
"This deal signifies our ongoing commitment to provide access to innovative treatments to patients worldwide," Cipla MD & Global CEO Subhanu Saxena said.
Generally, Rifaximin is used as an antibiotic.
Last year the company had announced the expansion of its existing collaboration with Meda by granting global commercialisation rights for a proprietary combination nasal spray product (fluticasone and azelastine) Dymista, Cipla said.
