NCT ID: NCT00532493

Last Updated: 2018-05-01

Results Overview

Change from baseline in frequency and/or severity of combat trauma-related nightmares will be assessed by the CAPS Recurrent Distressing Dreams item. Possible range for Recurrent Distressing Dreams is 0-8. Higher score indicates more severe PTSD symptoms.

Measure
Prazosin Group
Subjects randomized to this arm will be on prazosin. prazosin: Subjects will be titrated up to the optimum tolerated dose based on the Dosing Algorithm. Males and females will be titrated differently with females titrated slower and to a lower maximum daily dose. The first dose will be taken while the participant is in bed for the night to avoid orthostatic syncope, an uncommon but recognized "first dose" effect of prazosin or any alpha-1 antagonist if started at a high dose. As a further precaution, male subjects will be advised to sit on the toilet for urination at night during the first week of dose titration. The first dose effect is avoidable by starting treatment with a low dose (1 mg at bedtime) and then titrating the dose upward gradually.

Subjects randomized to this arm will be on prazosin. prazosin: Subjects will be titrated up to the optimum tolerated dose based on the Dosing Algorithm. Males and females will be titrated differently with females titrated slower and to a lower maximum daily dose. The first dose will be taken while the participant is in bed for the night to avoid orthostatic syncope, an uncommon but recognized "first dose" effect of prazosin or any alpha-1 antagonist if started at a high dose. As a further precaution, male subjects will be advised to sit on the toilet for urination at night during the first week of dose titration. The first dose effect is avoidable by starting treatment with a low dose (1 mg at bedtime) and then titrating the dose upward gradually.

SECONDARY outcome

Timeframe: This secondary outcome measure was administered at baseline, 6, 10, 14, 18, 22 and 26 weeks (or early termination).

Population: 11 participants in the prazosin group have missing data on this item at one or more of the follow-up weeks; 9 participants in the placebo group have missing data at one or more of the follow-up weeks

Change from baseline in possible range for SF-12 MCS is 5-76. Higher SF-12 score indicates better level of health.
