BACKGROUND Patients with ALS commonly exhibit pseudobulbar affect. METHODS The authors conducted a multicenter, randomized, double-blind, controlled, parallel, three-arm study to test a defined combination of dextromethorphan hydrobromide (DM) and quinidine sulfate (Q) (AVP-923) for the treatment of pseudobulbar affect in ALS. Q inhibits the rapid(More)
Pseudobulbar affect (PBA) is an affective disinhibition syndrome associated with various neuropathologies, which is characterized by involuntary and inappropriate outbursts of laughter and/or crying. The PBA syndrome can be socially and occupationally disabling, and it is largely unrecognized in clinical settings. Validated instruments to distinguish PBA(More)
OBJECTIVE To evaluate the efficacy and safety of DM/Q (capsules containing dextromethorphan [DM] and quinidine [Q]) compared with placebo, taken twice daily, for the treatment of pseudobulbar affect over a 12-week period in multiple sclerosis patients. METHODS A total of 150 patients were randomized in a double-blind, placebo-controlled study to assess(More)
BACKGROUND Pseudobulbar affect (PBA) is associated with neurological disorders or injury affecting the brain, and characterized by frequent, uncontrollable episodes of crying and/or laughing that are exaggerated or unrelated to the patient's emotional state. Clinical trials establishing dextromethorphan and quinidine (DM/Q) as PBA treatment were conducted(More)
An important trend in materials science is the use of increasingly sophisticated methods to control composition and microstructure during processing. Near-surface modification by ion implantation and laser treatment is one of these new methods for tailoring material properties. Novel materials have been formed which are far from thermodynamic equilibrium(More)
BACKGROUND AND OBJECTIVE Dextromethorphan/quinidine (DMQ) is the first agent indicated for the treatment of pseudobulbar affect. Dextromethorphan, the active ingredient, is a low-affinity, uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist. This study evaluated the potential for a drug-drug interaction (DDI) of DMQ with memantine, which is also(More)
