Description

No large-scale controlled clinical trials of symptomatic therapy for painful HIV-related neuropathy have been attempted. Both amitriptyline and mexiletine have been useful in the management of painful neuropathies; however, both are associated with certain toxicities. In this comparative study of amitriptyline and mexiletine, benztropine mesylate also will be included as an active placebo to mimic the side effects of the study drugs. Patients are randomized to receive amitriptyline, mexiletine, or benztropine mesylate as an active placebo to mimic the mild side effects associated with both...
