Exactly. The drug described is an add-on meant to prevent the side effects of the therapeutic drug. You might look at it as potential competition, or you might look at it as evidence for the need for Pro Neura.
Titan's ropinirole implant represents a new way of delivering the therapeutic drug without creating the side effects.
Ropinirole, when delivered intravenously to humans, has been shown not to create side effects. The hope is that the implant will mirror the effect of an IV. Ropinrole pills have a life of 4-5 hours in the body, requiring dosing at least 4 times a day. And so the peaks and troughs are felt 4 times a day.
If the ropinirole implant works, it's possible the potential market reach for ropiniole expands beyond combination therapy to monotherapy (ropinirole is approved for monotherapy, but is generally used more often as an "add-on").
