Bisolvon Cough Syrup

Bisolvon is a long-standing brand specializing in cough relief products, particularly known for its active ingredient, Bromhexine. It was originally developed in Germany by the pharmaceutical company Boehringer Ingelheim in the 1960s. The brand became a household name globally for its efficacy in thinning mucus to help clear the airways.

In 2017, the brand's ownership shifted significantly when the French multinational pharmaceutical company Sanofi acquired Boehringer Ingelheim's consumer healthcare business in a massive asset swap deal. Today, Bisolvon is managed under Sanofi's Opella division (formerly Sanofi Consumer Healthcare). While manufacturing is decentralized across Europe to serve various markets, the brand remains a cornerstone of Sanofi's respiratory portfolio, headquartered in France.
