Abstract

The invention relates to a multi-trace-element injection (II) medicine composition capable of improving compatible stability and a preparation method thereof. By virtue of the strong buffer capacity of citric acid-Na2HPO4 buffer pair and the chelation action of citric acid and trace elements, the multi-trace-element injection (II) medicine composition prepared by the preparation method disclosed by the invention can still keep a stable pH degree when used together with other injections, thus preventing the trace elements from forming hydroxide precipitates due to the change of the pH after compatibility, preventing the mutual action of the trace elements and other medicines, greatly improving the safety of medication, and improving the compliance of patients to medicines.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a pharmaceutical composition of various trace element injections (II) and a preparation method thereof. Background technique [0002] The human body is composed of more than 50 elements, which can be divided into two categories: macro elements and trace elements according to the content of elements in the human body. Any element that accounts for more than one ten thousandth of the total weight of the human body, such as carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, calcium, magnesium, sodium, etc., is called a constant element; any element that accounts for less than one ten thousandth of the total human body weight Elements such as iron, zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, etc., are called trace elements (iron is also called semi-trace elements). The content of trace elements in the human body is really neg...
