Medications for Parkinson’s Disease
To the Editor:
As a pharmacist and care partner for my wife who has Parkinson’s disease (PD), I would like to offer the following comments regarding the “Pipeline Plus” feature in P&T (October 2014, pages 712–713) entitled “Steady Progress on Parkinson’s Disease.” This well-intentioned article has two errors/omissions that I would like to point out to your readers.
With regard to the dosage regimen for ropinirole (Requip) in PD: After initial titration, the typical treatment regimen for Parkinson’s disease is 9–24 mg total daily dose (divided three to four times daily).1
In addition, the monoamine oxidase-B (MAO-B) inhibitor selegiline was not included in the table of current therapies. This MAO-B inhibitor has been available for many years and is at least one-tenth the cost of rasagiline (Azilect) but is equally effective.2
I believe that this additional information is important for pharmacists working with PD patients to know.
