Abstract

The invention belongs to the technical field of medicine, and discloses levetiracetam composition, a preparation method and an application. The levetiracetam composition contains levetiracetam, sodiumacetate trihydrate, sodium chloride, glacial acetic acid and water for injection, and the average osmotic pressure molar concentration of the composition is 291-304 mOsmol / kg. The mass part ratio ofthe levetiracetam to the sodium acetate trihydrate to the sodium chloride is (250-500): (1.5-4): (0.5-12). The pH value of the composition is 5.5 + / -0.3. Aiming at the defects that a levetiracetam preparation in the prior art cannot be directly subjected to intravenous injection and the compliance of a patient is poor, the invention provides the isotonic levetiracetam injection preparation which meets the osmotic pressure requirement of intravenous injection and can be directly subjected to intravenous injection without compatibility.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a levetiracetam composition, preparation method and application. Background technique [0002] Epilepsy is a common nervous system disease. With the continuous development of the social level, problems such as air pollution and food safety have emerged, resulting in an increase in the incidence of epilepsy year by year. According to relevant data, the number of new epilepsy patients in my country every year reaches 400,000 people. Children belong to one of the groups with a high incidence of epilepsy, and the number of children with active epilepsy worldwide is more than 10 million. Children's epilepsy is also a hot issue in clinical practice. Because children's brain function is still not fully developed, and epilepsy drugs have certain toxic and side effects, which have certain adverse effects on children's physical and mental health, it is necessary to pay attention to clinic...
