Problems solved by technology

Before the 1970s, the main treatment for echinococcosis was surgical resection, but there were problems such as recurrence after surgery, leakage of a large number of protoscolees during surgery, causing widespread dissemination of echinococcosis, and some cases were not suitable for surgery.
However, such a large dose does not produce a good clinical effect. The results of clinical research at home and abroad show that the therapeutic effect of albendazole is better than that of mebendazole, and the cure rate is 30-40%.

Abstract

The invention provides a new formulation, namely oil suspension agent, of antiparasitic benzimidazole medicine. The oil suspension agent comprises benzimidazole medicine, a liquid grease, a suspending agent and a wetting agent. The oil suspension agent of benzimidazole medicine provided by the invention is used for treating echinococcosis and other parasitic diseases and can be used for increasing blood concentration and improving curative effects. The oil suspension agent has simple preparation method, good stability and easiness in popularization.

Description

Invention field [0001] The invention relates to antiparasitic drugs, in particular to the reformation of the dosage form of benzimidazole drugs, and more specifically to the oil suspension of benzimidazole drugs. Background technique [0002] Hydatid disease is a global human and zoonotic disease that causes serious damage to the health of humans and livestock. Hydatid disease is a disease caused by the larvae of Echinococcus parasitic in the body of an intermediate host. The main echinococcosis in my country are cystic echinococcosis (echinococcus granulosus) and alveolar echinococcosis (echinococcus granulosus). They are composed of larvae of Echinococcus granulosus (echinococcus granulosus). ) And larvae of Echinococcus multilocularis (Echinococcus multilocularis) parasitize human and animal tissues and organs. The development of echinococcosis in the body is slow, mainly due to chronic consumption, which often makes the patient lose the ability to work, especially the alveol...
