The results of these studies further document the clinical and health economic impact of factors that can complicate levothyroxine therapy. Levothyroxine is the most widely-used therapy for hypothyroidism and one of the most widely prescribed drugs in the world. In 2014, over 114 million prescriptions for levothyroxine were dispensed in the United States1.
"The CONTROL Study Program will help better describe the impact of malabsorption, tolerability and other clinical complications that are commonly observed with tablet formulations of levothyroxine," stated Walter Sandulli, VP of Marketing at Akrimax. "These can have a profound effect on the care of patients with hypothyroidism."
The protocols for all CONTROL studies were reviewed and approved by licensed Institutional Review Boards (IRBs) in accordance with US federal guidelines. Abstracts reporting the results of the three new CONTROL studies will be available after September 16, 2016 in a special online edition of Thyroid, the journal of the American Thyroid Association, and can be found at http://online.liebertpub.com/thy
About Akrimax Pharmaceuticals
Since 2011 Akrimax and IBSA have worked in collaboration to market Tirosint® (levothyroxine sodium capsules) a unique treatment for hypothyroidism. Tirosint is formulated with just four ingredients: levothyroxine, gelatin, glycerin and water. Clinical studies suggest that Tirosint may be an effective alternative for patients who suffer from tolerability or absorption problems that may be experienced with traditional levothyroxine tablet formulations.

Hypothyroidism is an endocrine disorder with numerous causes resulting in a deficiency in thyroid hormone. More than 27 million adults have been diagnosed with hypothyroidism.¹ Up to 13 million Americans have undiagnosed hypothyroidism.² About 2% of the U.S. population has pronounced hypothyroidism, and as much as 10% has subclinical (mild) hypothyroidism. The condition is most common in women over 40 years of age and in the elderly of both sexes.³ The signs and symptoms of hypothyroidism are nonspecific and may include fatigue, forgetfulness, depression, constipation, muscle cramps, weight gain, dry skin and hair loss.⁴ Laboratory tests (TSH, FT3 and FT4) are the most common way hypothyroidism is detected. Treatment with levothyroxine sodium oral tablets is the standard of care in hypothyroidism.
About Tirosint® (levothyroxine sodium) capsules
Tirosint (levothyroxine sodium) is the first and only levothyroxine therapy in a liquid gel cap. Tirosint gel caps are pure. Tirosint gel caps contain only T4, water, glycerin, and gelatin.
Tirosint is available in 10 dosage strengths, including an exclusive 13 microgram dose. Tirosint is administered as a single daily dose, preferably one-half to one-hour before breakfast. Tirosint should be taken at least 4 hours apart from drugs that are known to interfere with its absorption. Tirosint capsules cannot be cut or crushed. Due to the long half-life of levothyroxine, the peak therapeutic effect at a given dose of levothyroxine sodium may not be attained for 4-6 weeks.
Tirosint capsules are housed in blister packs to protect it from light and moisture. Blister packs are clearly marked for daily dosing. Tirosint should be protected from light and moisture and stored at 25°C (77°F); excursions permitted to 15°-30°C (59°-86°F).
IMPORTANT SAFETY INFORMATION
Thyroid hormones, including TIROSINT, either alone or with other therapeutic agents, should not be used for the treatment of obesity or for weight loss. In euthyroid patients, doses within the range of daily hormonal requirements are ineffective for weight reduction. Larger doses may produce serious or even life threatening manifestations of toxicity, particularly when given in association with sympathomimetic amines such as those used for their anorectic effects.
In patients with nontoxic diffuse goiter or nodular thyroid disease, particularly the elderly or those with underlying cardiovascular disease, levothyroxine sodium therapy is contraindicated if the serum TSH level is already suppressed due to the risk of precipitating overt thyrotoxicosis. If the serum TSH level is not suppressed, TIROSINT should be used with caution in conjunction with careful monitoring of thyroid function for evidence of hyperthyroidism and clinical monitoring for potential associated adverse cardiovascular signs and symptoms of hyperthyroidism.
Levothyroxine is contraindicated in patients with untreated subclinical (suppressed serum TSH level with normal T3 and T4 levels) or overt thyrotoxicosis of any etiology and in patients with acute myocardial infarction. Levothyroxine is contraindicated in patients with uncorrected adrenal insufficiency since thyroid hormones may precipitate an acute adrenal crisis by increasing the metabolic clearance of glucocorticoids. TIROSINT is contraindicated in patients with hypersensitivity to any of the inactive ingredients in TIROSINT capsules. TIROSINT is also contraindicated for anyone who may be unable to swallow a capsule (e.g., infants, small children).
Effects on bone mineral density – In women, long-term levothyroxine sodium therapy has been associated with increased bone resorption, thereby decreasing bone mineral density, especially in postmenopausal women on greater than replacement doses or in women who are receiving suppressive doses of levothyroxine sodium. The increased bone resorption may be associated with increased serum levels and urinary excretion of calcium and phosphorous, elevations in bone alkaline phosphatase and suppressed serum parathyroid hormone levels. Therefore, it is recommended that patients receiving levothyroxine sodium be given the minimum dose necessary to achieve the desired clinical and biochemical response.
Patients with underlying cardiovascular disease – Exercise caution when administering levothyroxine to patients with cardiovascular disorders and to the elderly in whom there is an increased risk of occult cardiac disease. In these patients, levothyroxine therapy should be initiated at lower doses than those recommended in younger individuals or in patients without cardiac disease and it should be noted that unlike levothyroxine sodium tablets, TIROSINT capsules cannot be cut in half. If cardiac symptoms develop or worsen, the levothyroxine dose should be reduced or withheld for one week and then cautiously restarted at a lower dose. Overtreatment with levothyroxine sodium may have adverse cardiovascular effects such as an increase in heart rate, cardiac wall thickness, and cardiac contractility and may precipitate angina or arrhythmias. Patients with coronary artery disease who are receiving levothyroxine therapy should be monitored closely during surgical procedures, since the possibility of precipitating cardiac arrhythmias may be greater in those treated with levothyroxine. Concomitant administration of levothyroxine and sympathomimetic agents to patients with coronary artery disease may precipitate coronary insufficiency.
Adverse reactions associated with levothyroxine therapy are primarily those of hyperthyroidism due to therapeutic overdosage such as fatigue, increased appetite, weight loss, heat intolerance, fever, excessive sweating, and other adverse reactions. This is not an exhaustive list. Please refer to TIROSINT's full Prescribing Information for a more comprehensive list of adverse reactions associated with hyperthyroidism.
