Description
Technical Field
The invention relates to the technical field of antianemia drugs, in particular to a preparation method of a folic acid solid preparation.
Background
Folic acid is a B-group vitamin, consists of pteridine, p-aminobenzoic acid and L-glutamic acid, and is widely present in meat, fresh fruits and vegetables. In 1931, Wills et al, a doctor in the Indian Mumbay obstetrics Hospital, discovered that yeast or liver concentrates had some effect on megaloblastic anemia symptoms in pregnant women, and these extracts were thought to have some anti-anemia factor; in 1935, yeast and liver extracts were found to have some effect on the anemia symptoms of monkeys, which were described as VM; in 1939, a factor against chicken anemia was found in the liver, known as VBe; in 1941, h.k.mitchell et al found that spinach contains a factor of streptococcus lactis, called folate. In 1945, R.B. Angier et al, when synthesizing pteroylglutamic acid, found that all the above factors were the same substance and completed the structure determination, and they were often referred to as folic acid thereafter. Therefore, folic acid is also called vitamin B9, anti-anemia factor, pteroylglutamic acid, etc.
Clinical administration forms of folic acid include oral administration and injection, and corresponding dosage forms include powder, injection, tablets and the like; among them, tablets are most commonly available on the market. Folacin tablets were first developed by MERUS LABS LUXCO II S.A R.L. company, marketed in France in 1947 under the trade name SPECIAFOLDINE, with a specification of 5 mg; subsequently, 1mg, 5mg specification folic acid tablets were marketed in the United states and Japan one after the other; in 2003, 0.4mg sized folic acid tablets were marketed. Folic acid tablets as antianemia agents; used for folic acid deficiency caused by various reasons and megaloblastic anemia caused by folic acid deficiency; preventive administration for pregnant and lactating women; folate deficiency caused by chronic hemolytic anemia.
According to the reports of related documents, folic acid is easy to destroy in an acid solution, unstable to heat, easy to lose at room temperature and easy to destroy by visible light. Japanese orange peel book states: folic acid was degraded by about 10% (1.0 g/150 ml) in a pH6.8 dissolution medium under direct sunlight for 7 hours. Therefore, the folic acid has poor stability, and certain difficulty is brought to preparation of the preparation. First, we prepared a commercially available formulation folic acid tablet (SPECIAFOL)DINE®) The inspection shows that the stability of the preparation sold on the market is poor, and each impurity in related substances continuously grows along with the increase of the standing time at room temperature; the maximum single impurity in the related substances reaches 1.12 percent in the near effective period, and exceeds the limit (1.0 percent) of the single impurity in the related substances of folic acid tablets in the current Chinese pharmacopoeia.
The patent of Shenyang Gulin pharmaceutical Co., Ltd for "a folic acid tablet and its preparation method" (application number: 201110280578.3) adopts wet granulation process, folic acid and lactose are mixed according to equal amount by gradually adding method, then mixed with starch and sucrose uniformly, granulated by adding 60% ethanol, wet-sized with 30 mesh screen, put the prepared wet granules into a hot air circulation oven at 55-65 ℃ for material drying for 3.5-4.5 hours, dried and sized with 30 mesh screen, mixed with magnesium stearate for 30 minutes and tabletted. The folic acid tablets obtained in the patent have uniform content, the dissolution rate is over 95 percent, but the stability of the folic acid tablets is not described; analysis shows that folic acid is unstable at high temperature, wet particles are placed in a hot air circulation oven at 55-65 ℃ for drying for 3.5-4.5 hours, and the particles are dried at high temperature for a long time, so that impurities are easily generated.
A folic acid solid preparation and a preparation method thereof (application number: 201410499518.4) applied by Beijing Silian drug industry Co., Ltd adopts a dry granulation process, which comprises mixing lactose, starch and folic acid, dry-pressing and crushing by a dry press under the pressure of 0.5-1.5Mpa, and screening and collecting 24-65 mesh granules; magnesium stearate was added to the resulting granules, and the mixture was subjected to tableting. As is well known, when dry granulation is performed, a large amount of heat is generated when a compression roller runs for a long time to extrude materials, and the medicine is possibly unstable, so that the risk that the product cannot be avoided is brought in the process. In addition, the dry granulation process has high requirement on auxiliary materials, the auxiliary materials with good adhesiveness and fluidity need to be selected, and the auxiliary materials are expensive, so that huge cost and trouble are brought to pharmaceutical companies.
