Ketanserin: An Effective Treatment Regimen for Digital Ischaemia in Systemic Sclerosis
1989
We have studied the therapeutic effects of ketanserin, a specific serotonin antagonist, on digital ischaemia in 11 patients with the CREST syndrome of systemic sclerosis. Ketanserin was administered as a bolus of 10 mg intravenously, followed by an infusion over 72 h and then oral therapy. Skin blood flow as measured by thermography, bolometry, ultrasound Doppler pulses and laser light scattering, showed significant improvement. There was also marked clinical improvement with a reduction in the pain and healing of digital ulceration. These improvements were maintained on oral therapy. In 7 patients detailed studies were performed comparing oral and intravenous ketanserin therapy. When ketanserin was administered as a bolus 10 mg intravenous dose, followed by an infusion at 2 mgh, steady state was reached by 12 h. Following oral treatment (40 mg tds) therapeutic blood levels were achieved.
