Definitions

  • the invention relates to a solid pharmaceutical preparation comprising levothyroxine sodium, gelatine, citric acid and a filler.

  • Levothyroxine sodium is used to treat thyroid hormone deficiency, and occasionally to prevent the recurrence of thyroid cancer.
  • very low daily doses of levothyroxine sodium are used in the range from 25 to 300 ⁇ g. Due to its high potency it is very important to avoid dosage variations as this may cause serious symptoms of hypothyroidism such as severe depression, fatigue, weight gain, constipation, cold intolerance, swelling, and difficulty concentrating, if levothyroxine sodium is underdosed, or of hypothyroidism, such as pain, heart palpitations, or cardiac arrhythmias, if levothyroxine sodium dosis is too high. Therefore, storage stability of pharmaceutical preparations containing levothyroxine sodium is a critical issue.

It was found that the basic pH modifying additives sodium carbonate, sodium bicarbonate and magnesium oxide lead to improvement of the stability of levothyroxine sodium tablets whereas acid pH modifying additives tartaric acid and citric acid lead to impairment of stability.
  • WO 99/59551 A1 teaches that storage stability of levothyroxine sodium containing solid pharmaceutical preparations can be improved by using gelatine as a binder. As described in the introduction such stabilized formulation has been developed in order to meet the increased requirements on stability as established by the Food and Drug Administration (FDA) in 1996.
