"PEG feeding - lansoprazole blockages"

My partner has been totally dependent on a PEG tube for feeding and nil by mouth for several months (hopefully back to eating and drinking normally soon!). 

One issue we came across was administering lansoprazole, as some dispersible tablets caused regular problems with the PEG becoming blocked. Usually we managed to unblock the tube ourselves (after much flushing, pushing and pulling and the associated anxiety!) but on one occasion, we had to call out the nurse. One particular brand caused all the problems we had as it seemed to "clump" much more than others. I've spoken to our local pharmacy and they've made a note. I wondered if this was something that was flagged elsewhere as an issue, and if not, could it be, so that other PEG users don't have the unnecessary anxiety of avoidable tube blockages? Many thanks :)
