The drug is effective for obstruction, phobia, hypochondriac syndromes (including those resistant to other tranquilizers), it is also indicated for psychogenic psychoses, panic reactions, etc., as it relieves anxiety and fear. Phenazepam is not inferior to some antipsychotics in terms of sedative and mainly anti-anxiety effect.
