History of Tirosint
- Founded: 2007
- Founders: IBSA Institut Biochimique SA (developer)
Tirosint's development originated from IBSA Institut Biochimique SA's expertise in hormone replacement therapies and its proprietary softgel capsule drug delivery technology. Levothyroxine (synthetic thyroxine, T4) is the standard treatment for hypothyroidism, a condition in which the thyroid gland does not produce sufficient thyroid hormone. Hypothyroidism affects approximately 5 percent of the US population and is one of the most common endocrine disorders, requiring lifelong daily levothyroxine replacement therapy in most patients.
Conventional levothyroxine tablets, including the original branded Synthroid (AbbVie) and numerous generic formulations, contain a variety of inactive ingredients (excipients) including dyes, lactose, gluten, and other fillers that are necessary for tablet manufacturing. While these excipients are generally well-tolerated, some patients experience absorption variability or sensitivities to specific inactive ingredients. Patients with conditions affecting gastrointestinal absorption, such as celiac disease, inflammatory bowel disease, or gastric bypass surgery, may also have difficulty absorbing levothyroxine from conventional tablets.
IBSA developed Tirosint as a softgel capsule formulation of levothyroxine that dissolves levothyroxine sodium in a glycerin and gelatin-based capsule, without the excipients found in conventional tablets. The softgel formulation is designed to provide more consistent and complete absorption of levothyroxine, particularly in patients with gastrointestinal conditions or sensitivities to tablet excipients. The absence of dyes, gluten, lactose, alcohol, and sugar also makes Tirosint suitable for patients with dietary restrictions or allergies to these substances.
The FDA approved Tirosint (levothyroxine sodium capsules) under NDA 021924. The package insert for Tirosint lists IBSA Institut Biochimique SA in Lugano, Switzerland as the manufacturer. Tirosint is available in multiple strengths (13 mcg, 25 mcg, 50 mcg, 75 mcg, 88 mcg, 100 mcg, 112 mcg, 125 mcg, 137 mcg, 150 mcg, 175 mcg, and 200 mcg) to accommodate the wide range of levothyroxine doses required by patients with varying degrees of hypothyroidism.
IBSA subsequently developed Tirosint-SOL, a liquid levothyroxine solution in unit-dose ampules, which received FDA approval for the US market. Tirosint-SOL provides an alternative for patients who cannot swallow capsules, including pediatric patients, elderly patients, and patients with dysphagia. The liquid formulation also allows for very precise dose titration, which can be important in patients who require fine adjustments to their levothyroxine dose.
Levothyroxine is one of the most widely prescribed medications in the United States, with tens of millions of prescriptions dispensed annually. The levothyroxine market is dominated by generic formulations and the branded Synthroid (AbbVie), which together account for the vast majority of prescriptions. Tirosint occupies a specialty niche within the levothyroxine market, targeting patients who have experienced absorption issues or sensitivities with conventional levothyroxine tablets.
Clinical studies have evaluated the bioavailability and absorption of Tirosint compared to conventional levothyroxine tablets. Research published in medical journals has demonstrated that Tirosint softgel capsules may provide more consistent levothyroxine absorption than conventional tablets in patients with conditions affecting gastrointestinal absorption, supporting the clinical rationale for the excipient-free softgel formulation.

This dual-formulation approach (capsule and liquid) has been noted as a significant advancement in personalized thyroid hormone replacement therapy.
Tirosint Recalls & Controversies
Tirosint has experienced one significant product recall that affected its liquid formulation but not the softgel capsule product. The recall was handled voluntarily by the manufacturer and did not result in reported adverse events.
Tirosint-SOL Voluntary Recall (2023): IBSA Pharma announced a voluntary recall on January 31, 2023, for 27 lots of Tirosint-SOL (levothyroxine sodium oral solution) due to potential subpotency issues. The recall affected only the liquid formulation and did not apply to Tirosint softgel capsules. The affected lot numbers were 220409, 220956, 220856, 220552, 221055, 220553, 221056, 220407, 220960, 220556, 221058, 220853, 220411, 220854, 220413, 220964, 220414, 220852, 220970, 220855, 220415, 221052, 220959, 220416, 221053, 220418, and 220560.
