same here, we have one med that comes as tablet with nice shiny bright blue coating!
All the other meds we get in liquid form, or are made to dissolve (like movicol).
I have a cute little glass pestle made for medications that is nearly antique I think. I put the tablets into a plastic medicine cup, then grind them a bit. It's actually the darn coating that needs crushing, inside that coating the actual medication is just powder anyway. Bit annoying, but I found quickly that I don't need to get too worried about grinding all that blue up tiny, which I was doing at first.
So I grind em a bit, then add hot water and let them sit while I get everything else set up. The blue coating is just a sugar coating so it dissolves quite neatly.
I put the water flush in the syringe, then while there is still around 30ml in the syringe, I tip half the blue water in, then give the medicine cup a bit of a swirl to make sure any sediment mixes in and tip it in.
I flush that with the next liquid meds which I've added to about 40 ml of warm water too.
Then finish with a straight water flush.
So far, it's been simple and no blockages or issues.
