Ketanserin in the treatment of Raynaud's phenomenon associated with generalized scleroderma

The British Journal of Dermatology

The efficacy of the 5-HT-2-receptor antagonist, ketanserin, in the treatment of Raynaud's phenomenon was assessed in a double-blind, placebo-controlled, crossover trial in nine patients with generalized scleroderma (GS). Each patient received ketanserin 20 mg or placebo three times a day in the 1st week and 40 mg ketanserin or placebo three times a day for the remaining 4 weeks, and was then crossed over for 5 weeks. Measurements were made of finger blood pressure and flow during a cold challenge test and patients recorded numbers of Raynaud's attacks. No significant improvement was found in reactions to cold provocation or in numbers of Raynaud's attacks during ketanserin treatment, but intolerable side-effects were common. Interactions with concomitant medication might be a possible explanation for this. We conclude that ketanserin in the dose given, is not effective in the treatment of Raynaud's phenomenon in GS.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
