Pharmacotherapy and motor recovery after stroke.

Stroke is one of the most prevalent neurological diseases worldwide, especially among the elderly population. There are various mechanisms that enhance motor recovery after a stroke. In clinical practice, we have the opportunity to enhance plasticity by designing specific rehabilitation programs. Areas covered: There are a variety of drugs commonly administered to people after the acute phase of a stroke. These drugs may modify motor performance. Herein reviewed is the evidence concerning motor enhancement or decline in stroke patients, produced by drugs commonly used in rehabilitation settings. An extensive review of animal and human studies is performed. Expert commentary: Many of the clinical trials carried out were underpowered. Modest evidence supports the claim that there are agents that can affect motor rehabilitation after a stroke. Amphetamine-like agents, serotonin reuptake inhibitors, and levodopa might improve motor outcomes, while antipsychotics, some antiepileptic drugs, and GABAmimetic drugs could impair the recovery process. To draw definite recommendations, more comprehensive knowledge about the efficacy, long-term effects, and safety of these drugs is required. There are also other interesting molecules that open a promising field for basic and clinical research, in the search for new therapeutic options.
