  • Title: Deanol acetamidobenzoate (Deaner) in tardive dyskinesia.
    Author: Stafford JR, Fann WE.
    Journal: Dis Nerv Syst; 1977 Dec; 38(12 Pt 2):3-6. PubMed ID: 590063.
    Abstract:
    A total of twenty-nine patients have thus far been treated with deanol in various dosage levels for periods ranging from five to thirty days. Clinical response has been pronounced, even dramatic, in seven patients, moderate but significant in nine patients, and slight to insignificant in thirteen others. Videotape rating and quantitative accelerometry, to the extent that they constitute novel and stress-inducing experiences may not be representative of global clinical changes. Deanol did not produce the anticipated elevation in choline levels postulated to be one mechanism of its action. The failure of deanol to achieve this effect may most probably be attributed to interval after last dose, to inadequate level of deanol or to some alteration in choline metabolism in the presence of deanol. The etiology of tardive dyskinesia at biochemical and structural levels is complex. For some patients improvement has been dramatic and clearly associated with deanol. Others appear to exhibit minimal response which cannot be differentiated from placebo or environmental effects. Our present strategy, in common with that of other authors includes the administration of a "challenge" dose of rapid acting injectable cholinomimetic agents (e.g. physostigmine) and dopamine-blocking agents (e.g. haloperidol) with placebo controls. In this manner therapy may be more rationally selected for long-term use and may logically include deanol. The correlation of such predictive challenges with response to long-term treatment is an area for much more well controlled study.
