The differential effects of so-called ‘first- and second-generation’ antipsychotic medications, when given in the first episode, on the long-term outcome of schizophrenia remain to be elucidated.
Aims
We compared the 9-year outcomes of individuals initially randomised to clozapine or chlorpromazine.
Method
One-hundred and sixty individuals with treatment-naive, first-episode schizophrenia or schizophreniform disorder in a mental health centre in Beijing, China were randomised to clozapine or chlorpromazine treatment for up to 2 years, followed by up to an additional 7 years of naturalistic treatment. The primary outcome was remission status for individuals in each group.
Results
Individuals in both groups spent essentially equal amounts of time in each clinical state over the follow-up time period (remission, 78%; intermediate, 8%; relapse, 14%). There were no significant differences on other measures of illness severity. The clozapine group was more likely than the chlorpromazine group to remain on the medication to which they were originally assigned (26% v. 10%, P = 0.01). There were no significant differences between the two groups on other secondary efficacy outcomes.
Conclusions
These findings support the comparability in effectiveness between antipsychotic medications but with slightly greater tolerability of clozapine in the treatment of first-episode psychosis.

Our [medical] curriculum covers a certain amount of study of the anatomy and physiology of the child about which mothers never ask us, but the information which they seek has to do with that which cannot be obtained from books, but rather is that sort of knowledge which has passed from mouth to mouth down through the centuries. Instead of asking mother or grandmother what should be done, the doctor is consulted. If her confidence is to be retained, the physician must be as familiar with the proper manner of bathing a baby as he is with the treatment of pneumonia, and he may render the baby as notable a service in one instance as in the other.
The doctor is taking the place more and more of the ‘advice offering neighbor,’ and it behooves him to be able to advise the mother correctly.

Physicians who take care of children are often called on to provide education and counseling about child rearing. Their advice may be especially important for the parents of young children, who grow and develop rapidly and sometimes seem to change overnight. Although physicians have been playing this role for at least the last century, the medical profession has given it greater attention in recent years in response to several factors: technological advances in medicine, a growing understanding of neuroscience and child development, and evolving systems of health care delivery.
