ReviewDopamine depleters in the treatment of hyperkinetic movement disorders.
Abnormal involuntary movements often improve in response to anti-dopaminergic drugs. In contrast to classic neuroleptics that block dopamine receptors, drugs that deplete presynaptic dopamine by blocking vesicular monoamine transporter type 2 (VMAT2) seem to be safer and have little or no risk of tardive dyskinesia. ⋯ This review, based largely on a detailed search of PubMed, will summarize the pharmacology and clinical experience with the various VMAT2 inhibitors. Expert commentary: Because of differences in pharmacology and pharmacokinetics these new VMAT2 inhibitors promise to be at least as effective as tetrabenazine but with a lower risk of adverse effects, such as sedation, insomnia, depression, parkinsonism, and akathisia.

Fracture healing is a complex physiological process. As impaired fracture healing is more frequent in osteoporotic subjects, anti-osteoporotic drugs could have some impact on this process. ⋯ A PubMed/Medline search was undertaken combining the terms 'fracture healing', 'anti-resorptive drugs', 'anabolic agents', 'anti-osteoporotic drugs'. Expert opinion: As clinical evidence on the role of anti-osteoporotic drugs in the process of fracture healing consists mainly of case reports or studies with a relatively small number of patients, large randomized clinical trials are needed in order to extend to the human setting the promising results on these agents as inductors or co-adjuvants of bone healing derived from animal studies.
