Benzodiazepines bipolar affective disorder

The discovery of benzodiazepines is a story of serendipity and certainly one that is difficult to predictably reproduce as part of a drug discovery program. Regrettably (or fortuitously), this story of the benzodiazepines is not an isolated example. Valproic acid, an agent used to treat epilepsy, migraine, chronic pain, and bipolar affective disorder, was also discovered by accident. [Pg.111]

Antipsychotic drugs are also indicated for schizoaffective disorders, which share characteristics of both schizophrenia and affective disorders. No fundamental difference between these two diagnoses has been reliably demonstrated. They are part of a continuum with bipolar psychotic disorder. The psychotic aspects of the illness require treatment with antipsychotic drugs, which may be used with other drugs such as antidepressants, lithium, or valproic acid. The manic phase in bipolar affective disorder often requires treatment with antipsychotic agents, although lithium or valproic acid supplemented with high-potency benzodiazepines (eg, lorazepam or clonazepam) may suffice in milder cases. Recent controlled trials support the efficacy of monotherapy with atypical antipsychotics in the acute phase (up to 4 weeks) of mania, and olanzapine and quetiapine has been approved for this indication. [Pg.633]

Carbamazepine is licenced as an alternative to lithium for prophylaxis of bipolar affective disorder, although clinical trial evidence is actually stronger to support its use in the treatment of acute mania. Carbamazepine appears to be more effective than lithium for rapidly cycling bipolar disorders, i.e. with recurrent swift transitions from mania to depression. It is also effective in combination with lithium. Its mode of action is thought to involve agonism of inhibitory GABA transmission at the GABA-benzodiazepine receptor complex (see also Epilepsy, p. 417). [Pg.391]

C. Clinical Use Lithium carbonate is used in the treatment of bipolar affective disorder (manic-depressive disease). Maintenance therapy with lithium decreases manic behavior and reduces both the frequency and the magnitude of mood swings. Drug therapy with neuroleptics or benzodiazepines may also be required at the initiation of lithium treatment. Antidepressant drugs may be required adjunctively during maintenance. Alternative drugs of value in bipolar affective disorder include carbamazepine, clonazepam, gabapentin, and valproic acid. [Pg.264]
