APPROACHES TO ACHIEVING PARTICLE SIZEOnce the target particle size of the API has been chosen, the method of achieving particle size has to be determined. There are a variety of approaches that can be used to achieve the desired particle size range for an API,These approaches include methods to directly achieve the desired particle size through crystallization or precipitation, the reduction of particle size using wet milling and particle size reduction by dry milling methods via jet mills or mechanical mills. This section will review several approaches used in the pharmaceutical industry and will describe the benefits and disadvantages of each as it relates to new API candidates. The approaches will be reviewed in order of their typical unit operations. Specifically, crystallization,wet milling and dry milling will be described
