Description

Stable mitoxantrone preparation

Technical Field

The invention belongs to the field of pharmaceutical preparations, and particularly relates to a stable mitoxantrone preparation.

Background

Mitoxantrone or mitoxantrone hydrochloride was first synthesized in 1979 by Murdock and lederrle laboratories in the united states and demonstrated its antitumor activity. Mitoxantrone hydrochloride was approved by the FDA in the united states in 1987 for injection production under the trade name Novantrone. Mitoxantrone hydrochloride has the chemical name of 1, 4-dihydroxy-5, 8-bis [ [2- [ (2-hydroxyethyl) amino ] ethyl ] amino ] -9, 10-anthraquinone dihydrochloride, and the structural formula of the mitoxantrone hydrochloride is shown as formula (I).

Mitoxantrone or mitoxantrone hydrochloride is an anthracycline antitumor agent, has a molecular structure similar to doxorubicin, has a planar aromatic ring and is easy to insert into the base pair of a DNA duplex, forcing the two base pairs to separate, growing DNA, causing structural deformation and cell death. Mitoxantrone or mitoxantrone hydrochloride is a nonspecific cell cycle drug, acts on chromosome replication process, particularly blocks cells in G2 phase, can kill cancer cells of any cell cycle, inhibits proliferation and non-proliferation cells, has high curative effects on breast cancer, acute leukemia and malignant lymphoma, and is also effective on digestive tract tumors such as gastric cancer and intestinal cancer, and prostate cancer, head and neck cancer, lung cancer, liver cancer, melanoma, soft tissue sarcoma, multiple myeloma, testicular tumor and ovarian cancer.

As a pharmaceutical formulation, an aqueous solution of mitoxantrone was approved for use. However, mitoxantrone has limited stability in aqueous solutions. It is known that mitoxantrone is susceptible to oxidative degradation if no measures are taken to reduce or preferably prevent degradation. For example, the degradation is performed to an impurity I represented by formula (II), an impurity II represented by formula (III), an impurity III represented by formula (IV), or an impurity IV represented by formula (V).

Impurity I (RRT 1.5):

impurity II (RRT 0.8):

impurity III (RRT 1.4):

impurity IV (RRT 2.8):

EP0236822B1 discloses a pharmaceutical formulation comprising mitoxantrone hydrochloride, sodium metabisulfite, the chelating agents disodium edetate and glycine, which is stabilized by the addition of the antioxidant sodium metabisulfite having a fixed pH, and the chelating agents disodium edetate and glycine.

CN102397561B discloses a self-assembled nanocrystalline injection comprising mitoxantrone sulfate, glycerol, acetic acid, sodium acetate and sodium metabisulfite, or comprising mitoxantrone hydrochloride, sodium chloride, acetic acid, sodium acetate and disodium edetate, which is stabilized by adding sodium metabisulfite or disodium edetate.

In CN102397561B is disclosed a mitoxantrone hydrochloride injection for lymphatic tracking comprising mitoxantrone hydrochloride, sodium metabisulfite and hydrochloric acid, which is stabilized by adding sodium metabisulfite.

However, the above-mentioned formulations are still unsatisfactory from the viewpoint of stability. Therefore, a mitoxantrone formulation with less adverse reactions, stable properties, less impurity content and suitability for clinical needs to be redesigned.
