N -methylglucamine antimonate is a drug that is used in the treatment of all forms of leishmaniasis . It was added to the World Health Organization 's Essential Medicines List in 1988. In Germany and Switzerland there are no approvals fordrugs containing N- methylglucamine antimonate.

Presentation and extraction

The compound can be prepared by reacting N -methylglucamine with antimony pentachloride or potassium hexahydroxyantimonate in an aqueous medium.

Chemical properties

structure

The structure of the present antimony (V) complex could not be elucidated for a long time. Investigations with current analytical methods suggest that N -methylglucamine antimonate is present as a mixture of different polymeric and zwitterionic structures, the composition in the solid state being different from that in solution.

Clinical information

N -methylglucamine antimonate is not absorbed and is therefore administered parenterally ( intramuscularly , subcutaneously ). It has to be used for weeks. This can result in considerable costs, especially for pets. The drug is quite toxic and side effects include vomiting , myalgia , headache , arthralgia, and thrombocytopenia , among others . In dogs , the administration leads to an improvement in clinical symptoms, but a relapse cannot be ruled out. In advanced leishmaniasis with pronounced liver damage and existing renal insufficiency, the prognosis is unfavorable and treatment should be avoided.

pharmacology

The mechanism of action is unclear. An inhibition of glycolysis is being discussed . Long-term therapy can lead to the development of resistance . The metabolism takes place over three stages and takes place mainly in the liver. Excretion takes place renally .

Trade names
