What this interaction means in plain words
Benztropine and Secretin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens

What to do
Where clinically feasible, withhold benztropine for at least five half-lives before secretin stimulation testing. Otherwise interpret results with caution.
