Another object of the present invention is to provide tablets comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose, wherein dissolution of Everolimus after 60 minutes from the composition of the present invention is faster than the composition using non HME grade hydroxypropyl methylcellulose when measured in USP apparatus II at 50 rpm using 500 ml purified water as dissolution media. Another object of the present invention is to provide process for the preparation of pharmaceutical composition comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose, wherein dissolution of Everolimus after 60 minutes from the composition of the present invention is faster than the composition using non HME grade hydroxypropyl methylcellulose when measured in USP apparatus II at 50 rpm using 500 ml purified water as dissolution media.
SUMMARY OF THE INVENTION
Present invention provides pharmaceutical composition comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose. Further the invention provides tablets comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose, wherein dissolution of Everolimus after 60 minutes from the composition of the present invention is faster than the composition using non HME grade hydroxypropyl methylcellulose when measured in USP apparatus II at 50 rpm using 500 ml purified water as dissolution media.
In another embodiment the present invention provides a process for preparation of pharmaceutical composition comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose.
DETAILED DESCRIPTION OF THE INVENTION
Present invention provides pharmaceutical composition comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose.
In another embodiment, the present invention provides a process for the preparation of pharmaceutical composition comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose. In another embodiment, the present invention provides pharmaceutical composition comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose, wherein dissolution of Everolimus after 60 minutes from the composition of the present invention is faster than the composition using non HME grade hydroxypropyl methylcellulose when measured in USP apparatus II at 50 rpm using 500 ml purified water as dissolution media.
Hot melt extrusion (HME) grade hydroxypropyl methylcellulose is currently marketed and available as AFFINISOL HPMC HME by Dow, which is designed for use in hot melt extrusion formulations. AFFINISOL HPMC HME is a water soluble amorphous polymer provided as a white to off-white powder currently available in 3 grades based on their molecular weight, i.e. HPMC HME 15 cps, HPMC HME 100 cps and HPMC HME 4M. The AFFINISOL™ HPMC HME has a glass transition temperature (Tg) of approximately 115 °C wherein non HME grade hypromellose typically exhibits a broad glass transition temperature from about 160 °C to 210 °C.
Generally, it is known to the person skilled in the art that dissolution of drug from a pharmaceutical composition can be controlled by hydroxypropyl methylcellulose. As the viscosity of hydroxypropyl methylcellulose increases, the dissolution of drug from pharmaceutical composition decreases. The high viscosity grade hydroxypropyl methylcellulose releases drug slower than low viscosity grade and vice versa. For clarity, dissolution of drug from a composition having hydroxypropyl methylcellulose 15 cps (low viscosity grade) will be faster as compared to hydroxypropyl methylcellulose 100 cps (high viscosity grade). Surprisingly and contrary to the general knowledge of the person skilled in the art, the present invention provides pharmaceutical composition comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose 15 cps, wherein dissolution of Everolimus after 60 minutes from the composition of the present invention is faster than the composition using non HME grade hydroxypropyl methylcellulose 3 cps, when measured in USP apparatus II at 50 rpm using 500 ml purified water as dissolution media. For the purpose of this specification, the term "non HME grade hypromellose" means hydroxypropyl methylcellulose which is not suitable for use in hot melt extrusion and has glass transition temperature is more than 160 °C.
In one of the embodiment, the present invention provides a composition comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose.
In another embodiment, the present invention provides tablets comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose, wherein dissolution of Everolimus after 60 minutes from the composition of the present invention is faster than the composition using non HME grade hydroxypropyl methylcellulose when measured in USP apparatus II at 50 rpm using 500 ml purified water as dissolution media and process for preparation of same.

Conclusion
example 1 is faster than the tablet of comparative example 1
Thus, pharmaceutical composition comprising Everolimus and hot melt extrusion (HME) grade hydroxypropyl methylcellulose can be prepared according to the present invention, wherein dissolution of Everolimus after 60 minutes from the composition according to present invention is faster than the composition using non HME grade hydroxypropyl methylcellulose. The pharmaceutical composition according to the present invention would be useful in achieving bioequivalence with regards to the reference drug product.
