Description
(extracted from source data)
INDICATION The primary therapeutic use for which benserazide is currently indicated for is as a combination therapy with levadopa for the treatment of Parkinson's disease in adults > 25 years of age, with the exception of drug-induced parkinsonism [F2, L2553].; ; At certain doses, the combination product of levodopa and benserazide may also be used to treat restless legs syndrome, which is sometimes associated with Parkinson's disease [L2553, T181].; ; There have also been some studies that have prompted the European Medicines Agency to confer orphan designation upon benserazide hydrochloride as a potential therapy for beta thalassaemia [F3]. Although studies are ongoing, no evidence has been formally elucidated as of yet [F3].
ROE Benserazide is rapidly excreted in the urine in the form of metabolites, mostly within the first 6 hours of administration, 85% of urinary excretion occurs within 12 hours [T181].; ; Elimination of radiolabelled 14C-benserazide was primarily by urinary excretion with 86% to 90% of an intravenous dose recovered in the urine while 53% to 64% of an oral dose was detected in the urine [F2, L2553]. The majority of the 14C-benserazide was ultimately accounted for in the urine within 48 hours after administration [F2, L2553]. Fecal recovery studies conducted over five to eight days accounted for the majority (about 30%) of the remainder of the administered 14C-benserazide [F2, L2553].; ; Ultimately, benserazide is almost entirely eliminated by metabolism [F2, L2553]. These metabolites are mainly excreted in the urine (64%) and to a smaller extent in the feces (24%) [F2, L2553].
TOXICITY Overdosage may lead to cardiovascular side effects like cardiac arrhythmias, psychiatric disturbances like confusion and insomnia, gastrointestinal effects like nausea and vomiting, and abnormal involuntary movements [F2, L2553].; ; Various LD50 values have been established for the rat model, including an oral LD50 of 5300 mg/kg in rats [MSDS].
