Drug loaded nanoresin particles |
| abstract |
The present invention relates to nano-resin particles that are suitable for pharmaceutical use and their use in the pharmaceutical field. The present invention provides nano-sized resin particles having a particle size distribution characterized in that D<sub>90</sub> value is between 200 nanometers to 900 nanometer and D<sub>10</sub> value is not less than 50 nanometers, wherein the nano-resin particles are in pure form and safe for pharmaceutical use. The present invention further relates to pharmaceutical compositions comprising these purified nano-resin particles and their use in the treatment of diseases.The present invention further provides a process for preparing purified, nano-sized resin particles that are suitable for pharmaceutical use, the process comprising steps of: (i) washing an ion exchange resin and suspending in an aqueous liquid, (ii) subjecting the suspension of (i) to wet milling for a period such that the particles have a particle size distribution characterized in that the D<sub>90</sub> value is between 200 nanometers to 900 nanometers and D<sub>10</sub> value is not less than 50 nanometers, (iii) subjecting the suspension of (ii) to purification to remove impurities, (iv) drying the purified suspension to obtain nano-resin particles in the form of dry powder. |
