Paclitaxel protein-bound particles for injectable suspension (albumin-bound) is paclitaxel formulated as albumin‑bound nanoparticles with a mean particle size of approximately 130 nanometers. Paclitaxel exists in the particles in a non-crystalline, amorphous state. Paclitaxel is a microtubule inhibitor. The chemical name for paclitaxel is 5β,20Epoxy-1,2α,4,7β,10β,13α-hexahydroxytax-11-en-9-one 4,10-diacetate 2-benzoate 13-ester with (2 R ,3 S )- N -benzoyl-3phenylisoserine. The empirical formula is C 47 H 51 NO 14 and the molecular weight is 853.91. Paclitaxel has the following structural formula: Paclitaxel is a white to off-white powder. It is highly lipophilic, insoluble in water, and melts at approximately 213°C to 216°C. Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) is supplied as a white to yellow, sterile, lyophilized powder or cake for reconstitution with 20 mL of 0.9% Sodium Chloride Injection, USP prior to intravenous infusion. Each single‑dose vial contains 100 mg of paclitaxel (bound to human albumin) and approximately 900 mg of human albumin (containing sodium caprylate and sodium acetyltryptophanate). Each milliliter (mL) of reconstituted suspension contains 5 mg paclitaxel formulated as albumin‑bound particles. Paclitaxel protein-bound particles for injectable suspension (albumin-bound) is free of solvents. Paclitaxel Structural Formula
