Problems solved by technology

[0007] The existing pharmaceutical preparations of recombinant human granulocyte-stimulating factor, including freeze-dried powder injection and injection solution, all have blood vessel irritation to varying degrees, such as local pain, etc. In order to overcome the above defects, some manufacturers add anesthetic ingredients to relieve pain However, analgesics will have adverse effects on some heart disease and cerebrovascular patients, so it is difficult to produce satisfactory results

Abstract

The invention relates to a pharmaceutical composition containing recombinant human granulocyte colony-stimulating factors. The pharmaceutical composition is prepared from a G-CSF stock solution, mannitol, chlorogenic acid, propylene glycol and water for injection.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a pharmaceutical composition containing recombinant human granulocyte stimulating factor. Background technique [0002] Recombinant human granulocyte-stimulating factor (G-CSF) is a drug used for: neutropenia caused by cancer chemotherapy and other reasons; and to promote the increase of neutrophils after bone marrow transplantation. [0003] G-CSF subcutaneous injection of 1 / 2 times, 1 times, 2 times of the commonly used clinical doses of this product has no significant impact on the behavior of mice; has no significant impact on the hypnotic dose and coordination and balance ability of pentobarbital sodium valve; The body temperature, arterial blood pressure, electrocardiogram, respiratory rate and depth of anesthetized dogs were not significantly affected. [0004] G-CSF can accelerate the recovery of peripheral blood leukocytes and bone marrow CFU-G in cyclophospha...
