Abstract
Benzonatate resinates of weak acid ion exchange resins having the same distribution of butyl 4-aminobenzoate homologs as exist in the benzonatate listed in the F.D.A. Orange Book as Application No. N011210. These resinates, in simulated gastrointestinal dissolution, release essentially the same distribution of butyl-4 aminobenzoate homologs as exist in the benzonatate listed in the F.D.A. Orange Book as Application No. N011210.
