Sumario:Sexual dysfunctions in people with schizophrenia are more severe than in the general population and are an important element in the treatment of schizophrenia. The mechanism of sexual dysfunction in patients treated for schizophrenia may be related to the side effects of antipsychotic drugs (hyperprolactinemia, suppression of the reward system), but it may also be related to the pathogenesis of schizophrenia itself. The aim of the study was to present the possibility of using amantadine in the treatment of sexual dysfunction in schizophrenia without the concomitant hyperprolactinemia. In an open and naturalistic case series study, five men treated for schizophrenia in a stable mental state were described. All patients reported a prolonged lack of sexual desire and sexual activity prior to treatment with amantadine. After exclusion of hyperprolactinemia, patients received amantadine 100 mg in the evening. Sexual dysfunction was assessed using subscales of the 14-point Short Form of the Changes in Sexual Functioning Questionnaire (CSFQ-14). On subsequent visits after 1, 2 and 3 months of administration of amantadine, an improvement in sexual functioning was observed in all patients. Although this is only the preliminary report, amantadine may become a new indication for the treatment of sexual dysfunction in schizophrenia patients.
