Oral medication is of course the rule. Liquid rather than solid formulations are easier for some patients to swallow - and harder for uncooperative ones to hide in their mouths. Intramuscular injections include ordinary short-acting ones, such as haloperidol 10 mg for severe agitation in a psychotic patient, and long-acting 'depot' preparations where the active medication is esterified and suspended in an oily form from which it is released slowly, such as haloperidol decanoate 100 mg every 4 weeks to keep chronic schizophrenia in remission. Intravenous injections are rarely used, and are unsafe with some psychotropic drugs.
