Abstract

The invention discloses freeze-dried orally disintegrating tablets of a pediatric ribavirin composition, and a preparation method thereof, and relates to the technical fields of a drug and a drug preparation method. The pediatric ribavirin composition comprises the following components, by weight, 6.0-16.32% of ribavirin, 81.62-90.01% of mannitol, 1.96-3.84% of gelatin, and 0.09-0.14% of sucralose. The invention further discloses freeze-dried orally disintegrating tablets of the pediatric ribavirin composition, and a preparation method thereof, wherein the pediatric ribavirin composition is prepared from the components. The freeze-dried orally disintegrating tablets have the following characteristics that: the components are simple; no water is required during taking; no chewing is required; the disintegrating time in the human oral cavity is less than 2 seconds; the absorption is rapid; the biological availability is high; the residue in the intestinal tract is less; the side effect is low; the liver first pass effect is low; the taste is good; and the tablets are especially suitable for infant patient taking.

Description

Technical field: [0001] The invention relates to the technical field of medicines and preparation methods of medicines, in particular to a freeze-dried orally disintegrating tablet of a ribavirin composition for children and a preparation method thereof. Background technique: [0002] Ribavirin is a broad-spectrum antiviral drug. Rapid oral absorption, ribavirin is clinically applicable to viral pneumonia caused by respiratory syncytial virus, bronchitis, influenza, skin herpes virus infection, herpetic stomatitis, mumps, epidemic hemorrhagic fever, children Adenovirus pneumonia, autumn diarrhea and other viral diseases. [0003] Ribavirin has the effect of inhibiting the growth of respiratory syncytial virus, influenza virus, hepatitis A virus, adenovirus and other viruses, but it does not change the adsorption, invasion and shedding of viruses, and does not induce the production of interferon. After the drug enters the cells infected by the virus, it is rapidly phosphory...
