The invention relates to a method for preparing a piroxicam beta-cyclodextrin inclusion compound micropill capsule, which comprises the following steps that: (1) in ammonia water with a mass percent concentration of between 23 and 25 percent, piroxicam and beta-cyclodextrin are dissolved into water with a temperature of between 65 and 85 DEG C according to a mol ratio of 1: 2.7-3.8; and (2) underthe atomizing pressure of between 0.05 and 0.5MPa, the airflow temperature is controlled to be between 75 and 85 DEG C, the flow rate is between 10 and 150ml/min, a piroxicam beta-cyclodextrin solution is sprayed on a pill core for spraying and coating, and a piroxicam beta-cyclodextrin inclusion compound micropill is prepared after immediate drying. The method does not need to add any auxiliary materials or excipients so as to reduce the relative process difficulty when including a piroxicam beta-cyclodextrin powder preparation, simplifies process flow, and reduces production cost.
