Tirosint

Tirosint is a specialized pharmaceutical product used for the treatment of hypothyroidism. It notably introduced the first gel cap formulation of levothyroxine, designed to improve absorption and avoid common intolerance issues associated with traditional tablets.

The brand originated in Switzerland, developed by IBSA (Institut Biochimique SA), a boutique pharmaceutical firm headquartered in Lugano. Unlike many major pharmaceutical brands that change hands frequently, Tirosint remains under the ownership of its founding company. The product is manufactured in IBSA’s state-of-the-art facilities in Switzerland to ensure high purity and quality standards for global distribution.

In the United States, Tirosint is commercialized through IBSA Pharma Inc., the American subsidiary of the Swiss group. The brand continues to be a core part of IBSA's endocrine care portfolio as they expand their presence in international markets.
