摘要

A new placebo-controlled clinical trial in 636 patients, as well as postmarketing data, have confirmed the unfavourable harm-benefit balance of fampridine: minimal reduction in walking difficulties and a risk of neuropsychiatric adverse effects, urinary infections, cardiac rhythm disorders and hypersensitivity reactions. Many patients with multiple sclerosis have difficulty walking, often caused by spasticity. In early 2018, there was no drug known to alleviate these problems satisfactorily (1). In 2011, fampridine (Fampyra0, Biogen Idec), a voltage-dependent potassium channel blocker, was granted conditional marketing authorisation (MA) in the European Union for patients with multiple sclerosis with walking disability (1,2). Analysis of the two clinical trials available at that time showed that fampridinehad an unfavourable harm-benefit balance: only marginal improvement in walking speed, with no real improvement perceived by the patients, while provoking neuropsychiatric adverse effects in particular (1).
