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, prodrugs or salts often substantially alter the in vivo behavior of the drug, and both the biology and toxicology of its druggability need to be re-evaluated

Abstract

The invention provides a novel preparation (soft capsule) for an antiparasitic drug-mebendazole. The content of the soft capsule comprises mebendazole, a suspending agent and liquid fat; and a capsule shell is mainly composed of gelatin, water, a plasticizer, a shielding agent and an antiseptic agent. The mebendazole soft capsule can increase plasma concentration and improve curative effect when being used for treating echinococcosis and other parasitic diseases. The soft capsule is simple in preparation method, has good stability and is easy to popularize.

Description

Invention field [0001] The invention relates to an antiparasitic drug, specifically to the reform of the dosage form of mebendazole, and more specifically to a soft capsule of mebendazole oil suspension. 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 alveolar echino...
