Abstract

objective: To evaluate the usefulness of fluoxetine hydrochloride in the treatment of patients with severe refractory orthostatic hypotension.

design: Prospective, nonrandomized study.

patients: Five patients (3 men, 2 women with a mean age of 67 ± 7 years with chronic symptomatic orthostatic hypotension resistant to or intolerant of other therapies.

methods: Symptoms and orthostatic responses were recorded in the baseline state. Fluoxetine hydrochloride 20 mg orally once daily was started and patients were reevaluated after 6 to 8 weeks of therapy.

results: All patients demonstrated orthostatic hypotension (20 mm Hg or greater decline in systolic blood pressure) associated with symptoms (eg, dizziness, vertigo, near syncope) in the baseline state. After 6 to 8 weeks of fluoxetine therapy, 2 patients reported resolution of all symptoms, 2 had a marked reduction in symptoms, and 1 patient experienced no effect. Orthostatic responses were attenuated in 4 of the 5 patients (80%).

conclusion: Fluoxetine hydrochloride may be an effective therapy for some patients with recurrent severe orthostatic hypotension refractory to other forms of therapy.

    Indications for drug therapy include the presence of multiple events or a single event resulting in injury.2 Medical therapy includes mineralocorticoids, vasoactive agents, acetylcholinesterase inhibitors, and serotonin antagonists.2,58-64 Beta-blockers have not been shown to be effective in 4 of 5 randomized trials and thus are no longer commonly used in the treatment of vasovagal syncope.

    Clonidine also appears to prevent acute reductions in sympathetic efferent activity in vasovagal syncope and in carotid sinus syndrome (34–37). Paroxetine is a highly selective serotonin (5HT) re-uptake inhibitor and has been shown to provide functional improvement in patients with vasovagal syncope (26–28). The mechanism by which this occurs is unclear, but animal and human evidence support a sudden increase in 5HT levels within the brainstem with activation of 5HT-2 receptors as a key to the mechanism of vasovagal syncope.
