Definitions
- the present invention relates to solid pharmaceutical compositions and the method of preparing the same. More specifically, the present invention relates to the preparation of stabilized pharmaceutical compositions, using pharmaceutically active ingredients such as levothyroxine sodium and liothyronine sodium (thyroid hormone drugs), in a solid dosage form. Said stabilized thyroid hormone compositions are prepared by blending the active moiety and B-sheet form of macrocrystalline cellulose and compressing to the desired solid dosage forms.
- pharmaceutically active ingredients such as levothyroxine sodium and liothyronine sodium (thyroid hormone drugs)
- Said stabilized thyroid hormone compositions are prepared by blending the active moiety and B-sheet form of macrocrystalline cellulose and compressing to the desired solid dosage forms.
- Thyroid hormone preparations of levothyroxine sodium and liothyronine sodium are pharmaceutical preparations useful to the treatment of hypothyroidism and thyroid hormone replacement therapy in mammals, for example, humans and dogs.
- Thyroid hormone preparations are used to treat reduced or absent thyroid function of any etiology, including human or animal ailments such as myxedema, cretinism and obesity.
- Hypothyroidism is a common condition. It has been reported in the United States Federal Register that Hypothyroidism has a prevalence of 0.5 percent to 1.3 percent in adults. In people over 60, the prevalence of primary hypothyroidism increases to 2.7 percent in men and 7.1 percent in women. Because congenital hypothyroidism may result in irreversible mental retardation, which can be avoided with early diagnosis and treatment, newborn screening for this disorder is mandatory in. North America, Europe, and Japan.
- Thyroid hormone replacement therapy can be a chronic, lifetime endeavor.
- the dosage is established for each patient individually. Generally, the initial dose Is small, The amount is increased gradually until clinical evaluation and laboratory tests indicate that an optimal response has been achieved. The dose required to maintain this response is then
- PMB_166039 1 PMANSO continued.
- the age and general physical condition of the patient and the severity and duration of hypothyroid symptoms determine the initial dosage and the rate at which the dosage may be increased to the eventual maintenance level, it has been reported that the dosage increase should be very gradual in patients with myxedema or cardiovascular disease to prevent precipitation of angina, myocardial infarction, or stroke.
- thyroid hormone treatment It is important that thyroid hormone treatment have the correct: dosage. Both under treatment and over treatment can have deleterious health impacts. In the case of under treatment, a sub-optimal response and hypothyroidism could result, under treatment has also been reported to be a potential factor in decreased cardiac contractility and increased risk of coronary artery disease. Conversely, over treatment may result in toxic manifestations of hyperthyroidism such as cardiac pain, palpitations, or cardiac arrhythmia's. In patients with coronary heart disease, even a small increase in the dose of levothyroxine sodium may be hazardous in a particular.
- Hyperthyroidism is a known risk factor for osteoporosis.
- the dose be kept to the lowest effective dose.
- Thyroid hormone drugs are natural or synthetic preparations containing tetraiodothyronine (T , levothyroxine) sodium or triiodothyronine (T 3 , liothyronine) Sodium or both.
- T 4 and T 3 are produced in the human thyroid gland by the iodination and coupling of the amino acid tyrosine.
- T 4 contains four iodine atoms and is formed by the coupling of two molecules of diiodotyrosine (DIT).
- T 3 contains three atoms of iodine and is formed by the coupling of one molecule of DIT with one molecule of monoiodotyrosine (MIT), Both hormones are stored In the thyroid colloid as thyroglobulin.
- Thyroid hormone preparations belong to two categories: (1) natural hormonal preparations derived from animal thyroid, and (2) synthetic preparations. Natural preparations include desiccated thyroid and thyroglobulin.
- Desiccated thyroid is derived from domesticated animals that are used for food by man (either beef or hog thyroid), and thyroglobulin is derived from thyroid glands of the hog.
- the United States Pharmacopoeia (USP) has standardized the total iodine content of natural preparations.
- Thyroid USP contains not less than (NLT) 0.17 percent and not more than (NMT) 0.23 percent iodine, and thyroglobulin contains not less than (NLT) 0.7 percent of organically bound iodine, Iodine content is only an indirect indicator of true hormonal biologic activity.
- T 4 and T 3 thyroid hormone are available from a number of producers.
- liothyronine sodium (T 3 ) tablets are available from Jones
- Levothyroxine sodium (T 4 ) is available under the tradename Levoxyl from Jones Pharma (now King Pharmaceuticals, Inc.), under the tradename Synthroid from Knoll Pharmaceutical, Mt. olive, New Jersey, and under the tradename Unithroid from Jerome Stevens Pharmaceuticals, Bohemia, New York.
- a veterinarian preparation of levothyroxine sodium is available under the tradename Soloxine from Jones Pharma, St. Louis, Missouri.
- thyroid hormone drugs are quite poor. They are hygroscopic and degrade in the presence of moisture or light, and under conditions of high temperature, The instability is especially notable in the presence of pharmaceutical excipients, such as carbohydrates, including lactose, sucrose, dextrose and starch, as well as certain dyes.
- U.S. Patent No. 5,22.5,204 (the '204 patent) is directed to improving the stability of levothyroxine sodium.

- Higher tablet density can be accomplished by adjusting a tableting machine to increase the compression ratio.
- Tableting machines are commonly known to practitioners in the art and include those available from Manesty and Stokes. It has been found that making such adjustments to the compression ratio results in poor tablet surface finish as well as inconsistent tablet weights.
- the design of the tableting dies must be adjusted, It has been determined that during the filling of the tableting dies, a minimum of 5-6 mm die overfill. In most cases this requires replacement of the tableting dies with dies an additional 2-3 mm deep.
- Example 1 tablets comprise the B-sheet microcrystalline cellulose while Control 1 tablets comprise the traditional a-form microcrystalline cellulose.
- the composition of Example I and Control 1 tablets are presented in Table 1 and stability test results In Table 2:
- Tablet quality is also dependent upon the storage of the B-sheet microcrystalline cellulose. Best results are achieved when the cellulose i5 received in drums or portable containers instead of bags. The bag form suffers from compression during transportation from raw material suppliers. Test results for tableting are presented in attached Exhibit A.
