@jeanninec By making that change, the drug manufacturer can increase the price significantly because the new version won't be generic.

Tonmya (sublingual cyclobenzaprine) is priced at approximately $916.32 for 30 tablets, while the average cost of Flexeril (cyclobenzaprine), available as a generic, without insurance only costs about about $20 for a 30-tablet supply of the 10 mg dosage.
