A recently granted patent (Publication Number: US11857680B2) discloses a pharmaceutical liposomal composition containing specific ingredients in precise proportions. The composition includes docetaxel, Soya Phosphatidyl Choline, Sodium Cholesteryl Sulfate, Sucrose, and a pH adjusting agent. The pH of the composition is maintained below 3.5, with an option for it to be around 3. Additionally, the liposomal composition is prepared using a specific process involving the dispersion of Soya Phosphatidyl Choline in a solvent mixture of methanol and tertiary butanol in a 1:1 ratio.
Furthermore, the patent claims specify that the liposomes in the composition have a d90 size of less than 200 nm. Another variation of the composition includes slightly different percentages of the ingredients, such as 0.9% w/w of docetaxel, 32% w/w of Soya Phosphatidyl Choline, 0.5% w/w of Sodium Cholesteryl Sulfate, and 66.5% w/w of Sucrose. The patent also covers a similar liposomal composition with the same ingredients and pH range, providing flexibility in formulation while maintaining the essential characteristics outlined in the claims.
