Abstract

Stable, injectable pharmaceutical compositions are provided, which are useful as ready-to-dilute (RTD) or ready-to-use (RTU) liquid injectable compositions comprising bendamustine or a pharmaceutically acceptable salt thereof, and which are suitable for intravenous administration. Preferably, solution formulations comprise (a) bendamustine, or pharmaceutically acceptable salts, solvates, or hydrates thereof, (b) at least one pharmaceutically acceptable non-aqueous solvent; (c) optionally, at least one pharmaceutically acceptable excipient, and (d) optionally, a pH adjuster, where the pharmaceutical composition is antioxidant-free, and formulated as a ready-to-dilute or ready-to-use liquid composition suitable for parenteral administration. The invention further relates to methods for manufacturing stable, antioxidant-free injectable solutions of bendamustine.
