Abstract

The invention discloses a pediatric acetaminophen composition and relates to the technical field of pharmaceutic preparations. The composition comprises the following components by weight: 13-32% of acetaminophen, 32-40% of mannitol, 2-4% of gelatin, 0.2-1.0% of xanthan gum, 32-40% of hydroxypropyl-beta-cyclodextrin with a medium degree of substitution and 0.1-0.15% of sucralose. A prepared pediatric acetaminophen freeze-drying oral disintegrating tablet containing above components is simple in components, needs no water when being taken, do not need to be chewed, works rapidly, has few residues in intestinal tract, is full in absorption and less in side effect and good in taste; the disintegration time of the tablet is no more than 2 minutes in an oral cavity of a human body, so that pediatric acetaminophen freeze-drying oral disintegrating tablet is especially suitable for being taken by infant patients.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a pediatric acetaminophen composition, a pediatric acetaminophen freeze-dried orally disintegrating tablet made from the composition and a preparation method thereof. Background technique [0002] Acetaminophen is an antipyretic and analgesic drug of the acetanilide class. By inhibiting cyclooxygenase, selectively inhibiting the synthesis of prostaglandins in the hypothalamic thermoregulation center, resulting in peripheral blood vessel dilation and sweating to achieve antipyretic effect, and its antipyretic effect is similar to that of aspirin; by inhibiting the synthesis of prostaglandins, etc. It is a peripheral analgesic, its effect is weaker than that of aspirin, and it is only effective for mild and moderate pain. At present, among the antipyretic and analgesic drugs, it is considered that the first choice drug should be acetaminophen, because of its sm...
