Homeopathy: a preventive approach to medicine?

By applying the principle of therapeutic similarity, homeopathy seeks to stimulate the organism to react against its own disturbs. For homeopathic medicines to awaken effective homeostasis responses they must be individualized, this means that they must be chosen according to their similarity to the set of characteristic symptoms in patients. In this way, by aiming at decreasing individual susceptibility predisposing to disease, homeopathic medicines have healing and preventive effects in many human illnesses. On the other hand, homeopathic medicines may have specific indications in the treatment and prevention of epidemic diseases provided they are also chosen according to the particular set of symptoms peculiar to a given epidemic, viz. the so-called “epidemic genius”, as historical examples show. This update paper discusses the epistemological foundations of Hahnemann’s homeopathy as a preventive medical approach, the scientific evidences supporting its clinical application and the minimum requirements to employ it both therapeutically and preventively in epidemics.

GOCOVRI® (amantadine) extended-release capsules in Parkinson's disease

Amantadine is an old, antiviral compound, which moderately improves motor behavior in Parkinson's disease. Its current resurgence results from an innovative, delayed uptake and extended release amantadine hydrochloride capsule, given at bedtime once daily. It is the only approved compound for reduction of involuntary movements, so called dyskinesia, in fluctuating orally levodopa treated patients. It additionally ameliorates ‘off’-intervals characterized by impaired motor behavior. These beneficial effects result from higher and more continuous brain delivery of amantadine. Future clinical research is warranted on preventive effects of this amantadine capsule combined with enzyme blockers of central monoamine oxidase B and peripheral catechol-O-methyltransferase on motor complications in orally levodopa treated patients, as all these pharmacological principles support the concept of continuous dopamine substitution.
