Nanosuspension Technologies for Delivery of Drugs

For ball mills, processing times of up to five days or longer may be required.Alternatively, processing times of less than 1 day (residence times of one minute up to several hours) are possible with the use of a high shear media mill.The naproxen particles must be reduced in size at a temperature which does not significantly degrade naproxen.

For example, ambient processing pressures are typical of ball mills, attritor mills and vibratory mills.Processing pressures up to about 20 psi (1.4 kg/cm 2 ) are typical of media milling.Milling must be carried out under acidic conditions, at a pH of from 2-6, preferably 3-5.
