Abstract

The invention relates to an aspirin eugenol ester-paracetamol compound sustained-release tablet. The aspirin eugenol ester-paracetamol compound sustained-release tablet is prepared from aspirin eugenol ester, paracetamol and vitamin C. The aspirin eugenol ester-paracetamol compound sustained-release tablet has effects of effectively relieving fever, headache and upper airway symptoms caused by common cold and influenza and various symptoms caused by the hay fever, is suitable for treating cold-related symptoms, and contains active components which are released slowly.

Description

[0001] technical field [0002] The invention discloses an aspirin eugenol ester acetaminophen sustained-release tablet, and also provides a preparation method thereof, belonging to the technical field of medicine. technical background [0003] Aspirin eugenol ester (AEE) is a combination of eugenol, a volatile oil component extracted from the traditional Chinese medicine clove, which has antibacterial, antipyretic, and antioxidant effects, and anti-inflammatory, analgesic, Antipyretic, anticancer and other classic western medicine aspirin synthesizes a new type of anti-infective drug through esterification reaction. This drug solves the shortcomings and side effects of the two drugs used alone. At the same time, it can also relieve various secondary symptoms such as fever, pain, and inflammation caused by germs, achieve the effect of treating both symptoms and root causes, and reduce drug costs while curing diseases faster and better. [0004] Acetaminophen is an analgesic...
