The group is divided into therapeutic subgroups: N05A - Antipsychotics N05B - Anxiolytics N05C - Hypnotics and sedatives
N05A - Antipsychotics
This group comprises drugs with antipsychotic actions (i.e. neuroleptics). Reserpine is classified in C02 - Antihypertensives. Antipsychotics in combination with antidepressants are classified in N06C - Psycholeptics and psychoanaleptics in combination. The group is subdivided mainly according to chemical structure.
The DDDs are based on the treatment of psychosis. The substances in this group are sometimes used for other indications in much lower doses. For depot injections, the DDDs are based on the average recommended doses divided by the dosing interval.
N05AX - Other Antipsychotics
This group comprises antipsychotics which cannot be classified in the preceding groups.
