Article: Pharmacological treatment of vertigo.
[show abstract] [hide abstract]
ABSTRACT: This review discusses the physiology and pharmacological treatment of vertigo and related disorders. Classes of medications useful in the treatment of vertigo include anticholinergics, antihistamines, benzodiazepines, calcium channel antagonists and dopamine receptor antagonists. These medications often have multiple actions. They may modify the intensity of symptoms (e.g. vestibular suppressants) or they may affect the underlying disease process (e.g. calcium channel antagonists in the case of vestibular migraine). Most of these agents, particularly those that are sedating, also have a potential to modulate the rate of compensation for vestibular damage. This consideration has become more relevant in recent years, as vestibular rehabilitation physical therapy is now often recommended in an attempt to promote compensation. Accordingly, therapy of vertigo is optimised when the prescriber has detailed knowledge of the pharmacology of medications being administered as well as the precise actions being sought. There are four broad causes of vertigo, for which specific regimens of drug therapy can be tailored. Otological vertigo includes disorders of the inner ear such as Ménière's disease, vestibular neuritis, benign paroxysmal positional vertigo (BPPV) and bilateral vestibular paresis. In both Ménière's disease and vestibular neuritis, vestibular suppressants such as anticholinergics and benzodiazepines are used. In Ménière's disease, salt restriction and diuretics are used in an attempt to prevent flare-ups. In vestibular neuritis, only brief use of vestibular suppressants is now recommended. Drug treatments are not presently recommended for BPPV and bilateral vestibular paresis, but physical therapy treatment can be very useful in both. Central vertigo includes entities such as vertigo associated with migraine and certain strokes. Prophylactic agents (L-channel calcium channel antagonists, tricyclic antidepressants, beta-blockers) are the mainstay of treatment for migraine-associated vertigo. In individuals with stroke or other structural lesions of the brainstem or cerebellum, an eclectic approach incorporating trials of vestibular suppressants and physical therapy is recommended. Psychogenic vertigo occurs in association with disorders such as panic disorder, anxiety disorder and agoraphobia. Benzodiazepines are the most useful agents here. Undetermined and ill-defined causes of vertigo make up a large remainder of diagnoses. An empirical approach to these patients incorporating trials of medications of general utility, such as benzodiazepines, as well as trials of medication withdrawal when appropriate, physical therapy and psychiatric consultation is suggested.CNS Drugs 02/2003; 17(2):85-100. · 4.80 Impact Factor -
Article: Placebo effect and placebos: what are we talking about? Some conceptual and historical considerations.
[show abstract] [hide abstract]
ABSTRACT: Placebos and the placebo effect have always been present in medical history. However, they have not received the same consideration over the years. Somewhere between art and science, the placebo historical references come from Ancient Egypt and cross over the major civilisations, beliefs and scientific advances. The use of placebo as a methodological tool has assumed a leading role in the last 50 years and has become an important role in controlled clinical trials, the main element of the "evidence-based-medicine" paradigm. Knowledge of the conceptual and historical considerations of placebo may help to understand its role in medical practice. Even without a consensual definition, and assuming that the placebo effect does not seem to be fully dependent on a placebo administration, one issue seems unquestionable: the placebo effect is present in clinical practice and in clinical trials, no matter which name we choose to call it.European Journal of Clinical Pharmacology 09/2003; 59(4):337-42. · 2.85 Impact Factor -
Article: [Nocebo effect: the other side of placebo].
[show abstract] [hide abstract]
ABSTRACT: Administration of drugs is often followed by beneficial (placebo effects) and harmful (nocebo effects) effects that are not always related to their mechanism of action. Nocebo effects are rather unknown even when may be the source of many adverse reactions which could be erroneously attributed to drug therapy. Some mechanisms have been postulated which might be associated with the development of nocebo effects. Expectancy, learning and classical conditioning are probably important in the psychological domain. The neuropharmacological substrate is much less known yet an opioid peptide-cholecystokinin interaction has been suggested. At the clinical setting, a nocebo effect should be suspected in those patients who present common unspecific symptoms after drug administration and have a tendency to somatize. An early detection of these patients may contribute to the prevention of the nocebo effect.Medicina Clínica 05/2004; 122(13):511-6. · 1.38 Impact Factor
