Vivalan, a new anti-depressant-report on an out-patient trial.

The study on 20 patients referred from the psychiatric out-patients of the Jinnah Postgraduate Medical Centre, who were given Vivalan showed marked improvement in 14 patients (70%). Three showed mild improvement while three did not respond. The drug appears to be an advance in the range of anti-depressants presently available. It is of interest to note that Vivalan is not tricyclic compound, nor does it inhibit monoamine oxidase in vitro.
