[Treatment of Raynaud's syndrome in systemic connective tissue diseases with calcium antagonists]

The results of a short and a prolonged treatment of Raynaud's syndrome with calcium antagonists are presented. The efficacy of Nifedipin, Verapamil and Fendiline was evaluated in a 14 day treatment of 61 patients with Raynaud's syndrome. Nifedipin and Fendiline was evaluated in a 14 day treatment of 61 patients with Raynaud's syndrome. Nifedipine and Fendiline were most efficient but Fendiline led to more untoward reactions. Verapamil was least efficient and exerted a weak vasoactive action. The influence of the hemocirculation indices on all drugs studied was insignificant. 20 patients with systemic sclerodermia were given 30-60 mg Nifedipin daily in the course of one year and the frequency, duration and expression of the attacks of Raynaud's syndrome decreased practically twice. The study allows the recommendation of Nifedipin as the drug of choice for the treatment of Raynaud's syndrome in the systemic connective tissue diseases.
