[Haloperidol decanoate. Results of an open-ended multicentric study in chronic psychotic states].
An open multicentric study of 196 in-patients was carried out in 9 centres. After an initial stabilization (min. 15 days) with oral haloperidol, patients received haloperidol decanoate IM for at least 24 weeks (or a minimum of 9 injections).


RESULTS
- esterification of haloperidol increased the duration of its efficacy (interval between 2 injections: average 4 weeks) without interfering with its therapeutic activity (global appreciation scale, BPRS at each injection and at the end of the treatment); - equivalent quantities of haloperidol injected at a time were 15 to 20 times those administered daily during the initial stabilisation period; - side-effects were not different with haloperidol decanoate as compared to those of the previous period (haloperidol).
