injectable apo has been accepted as a pd drug maybe even longer than l-dopa so i think a benefit analysis has been done for the sublingual so i'm assuming the mfg has laid out the most common situations where a patient would benefit by being able to go ON faster, even if it's just 20minutes. forget the food, there are times when i need to get ON 20 min. faster, this could be when i'm away from home and going OFF would ruin a good time. someone still working could greatly benefit. i agree having a better planned drug regime is the better choice but there are days when i barely come ON due to constipation or some other mysterious cause where i need that rescue drug, C/L just ain't working. if i have to get up at night because my house is on fire i'm going to grab that rescue drug to get on ASAP, even if it's only 20minutes sooner.
