Minocycline is an antibiotic agent that also reduces lymphocyte access to the central nervous system and –according to some reports- also has the potential to have neuroprotective effects. In a recent, very small Canadian study is was shown that orally administered minocycline can suppress MRI activity in relapsing MS. Among potential future therapies for MS, minocyclin is interesting because it is given orally and has a favourable safety record. Further studies are ongoing.
