The advantages and drawbacks of depot antipsychotics and some myths abouts this therapy are reviewed as well as pharmacological characteristics of long-acting risperidone, so far the only long-acting second-generation antipsychotic in clinical use. The e-STAR (Electronic Schizophrenia Treatment Adherence Registry) study and its interim results obtained in the Czech and Slovak Republics are briefly presented.
