Depot haloperidol decanoate for schizophrenia.

The mainstay of treatment for schizophrenia is the antipsychotic group of drugs. These are usually given orally but compliance with medication given by this route may be difficult to quantify. Problems with treatment adherence are common. The development of depot injections in the 1960s gave rise to their extensive use as a means of long-term maintenance treatment. Haloperidol decanoate is one depot drug available in clinical practice.
