There are various opinions about crushing more than one medication at a time. Different pharmacists require only 1 medication to be crushed at a time. Other pharmacists approve crushing a collection of meds at a time. There doesn't seem to be standard guidance from the pharmacy world.
The PP06 pouch can hold 50ml of liquid. We have tested 8 pills in one crushing and with enough crushing and rolling to pulverize medications into fine dust, it has been effective handling 8 different medications.
