Description
A stable ready to dilute injectable pharmaceutical formulation of Mitomycin
RELATED APPLICATIONS
This application is related to Indian Provisional Application IN202121042020 filed 17th September, 2021 and is incorporated herein in its entirety.
FILED OF THE INVENTION
The present invention relates to a stable ready to dilute (RTD) injectable pharmaceutical formulation of Mitomycin or a pharmaceutically acceptable salt thereof. The said formulation further comprises N, N - Dimethylacetamide (DMAC), Polyethylene glycol (PEG) and optionally other pharmaceutically acceptable excipients. Further, the present invention discloses process for the preparation of the said formulation.
BACKGROUND OF THE INVENTION
Mitomycin is blue-violet crystalline powder. Mitomycin has an empirical formula of C15H18N4O5, a molecular weight of 334.33, and the following structural formula:
(Mitomycin)
Mitomycin is marketed as topical and injectable dosage forms. The injectable dosage forms are available as lyophilized powder for injection.
Historically, due to stability issue of Mitomycin, currently, the marketed injectable dosage form is available in the form of lyophilized powder under the brand name MUTAMYCIN by Bristol Myers Squibb, MITOZYTREX by Supergen and MITOMYCIN by Medac. The marketed formulation of MUTAMYCIN contains Mitomycin as active pharmaceutical ingredient and mannitol as pharmaceutically acceptable excipients. MUTAMYCIN are available as three dosage strengths i.e., 5 mg per vial, 20 mg per vial, and 40 mg per vial. Further, marketed formulation of MITOZYTREX contains mitomycin as active pharmaceutical ingredient and hydroxypropyl β cyclodextrin (HPβCD) as pharmaceutically acceptable excipients. MITOZYTREX is available as one dosage strengths i.e., 5 mg per vial. Furthermore, marketed formulation of MITOMYCIN by Medac contains mitomycin as active pharmaceutical ingredient and urea as pharmaceutically acceptable excipients. MITOMYCIN by Medac are available as four dosage strengths i.e., 2 mg per vial, 10 mg per vial, 20 mg per vial, and 40 mg per vial. All lyophilized products require reconstitution of the powder prior to administration to the patient in need thereof.
US10688049 discloses a lyophilized powder composition for parenteral administration comprising Mitomycin, which are characterized by high stability and can be rapidly reconstituted to form solutions. Further, it discloses a solution comprising a mixture of tert-butanol and water, and urea as additives.
US6048845 discloses a composition comprising an anti -ulceration effective amount of a substituted cyclodextrin compound, a cytotoxic drug i.e. Mitomycin, and mannitol as bulking agent.
From the prior-art literature, it can be concluded that Mitomycin has issues related to stability, solubility, reconstitution and their final concentration prior to
administration when manufactured in the form of lyophilized powder formulation. The previously available lyophilized product was facing the problems associated with longer reconstitution time and difficulty in making final concentration within the limit prior to administration.
Considering the prior efforts as disclosed in the background, a need exists which would addresses the issue of solubility, stability and improved reconstitution time of formulation of Mitomycin and provides an alternative as a stable ready to dilute injectable pharmaceutical formulation of Mitomycin.
