|---|---|
| Study design | Randomised single blind active controlled parallel group trial |

| Ethics approval(s) | Received from local medical ethics committee |
| Health condition(s) or problem(s) studied | Depression |
| Intervention | Patients start with either phenelzine 15 mg or lithiumcarbonate 200 mg. The dose will be increased with phenelzine 15 mg or lithiumcarbonate 200 mg after 4-8 days. The minimum daily dose of phenelzine is 15 mg and the maximum daily dose is 60 mg. Lithium is dosed to reach a serum level between 0.6-0.8 mmol/l. |
