"During the phase 1 (titration), it is planned to increase dopamine by maximum 0.25 mg per hour over the daytime period, which corresponds to a maximum increase of 4.5 mg per day (based on the 18 hours of the daytime period, since nocturnal needs are much less important).~Then, depending on tolerance and efficacy, conservative titration will be continued for a target dose of 30-87 mg per day.~During the phase 2 (efficacy), the treatment will be maintained at the minimum effective dose, planned between 30 and 87 mg per day, for 30 days."
