Stable pharmaceutical composition of amorphous canagliflozin
A recently granted patent (Publication Number: US11857559B2) discloses a stable pharmaceutical composition comprising amorphous canagliflozin, lactose, microcrystalline cellulose, polysorbate 80, croscarmellose sodium, and magnesium stearate. This composition, prepared using a fluidized bed processor with two granulating fluids, is free of canagliflozin hemihydrate and remains stable for a minimum of 6 months at 40°C/75% RH. Importantly, it demonstrates comparable bioavailability to commercially available canagliflozin hemihydrate tablets.
The composition, as outlined in the patent claims, consists of specific weight percentages of each ingredient, with amorphous canagliflozin ranging from 30-50% w/w, lactose and microcrystalline cellulose at 30-50% w/w, croscarmellose sodium at 10-20% w/w, polysorbate 80 at 1-3% w/w, and magnesium stearate at 0.5-2% w/w. Additionally, the use of granulating fluids, specifically a solution of polysorbate 80 in water and lactose in water, is highlighted in the patent for the preparation of this stable pharmaceutical composition. Furthermore, the option to coat the composition with a coating agent is also mentioned in the claims, potentially offering additional benefits in terms of stability and drug release profiles.
