"We are exploring all our options to deal with these prohibitory orders," Merck said in a filing to BSE.
The company's two drugs, Cosome Expectorant and Cosome LCD, have been banned from manufacturing and sale, courtesy government notification dated March 10, 2016, it added.
"The company has immediately stopped the manufacturing and sale of these drugs," Merck said.
These dugs were manufactured by the company after having requisite licence from the state FDA. The drugs are having well established efficacy and safety profile over the years in Indian markets, it added.
