The effect of phenothiazines-trifluoroperazine frenolone, majeptile and aminazine on contractility of papillar muscle of Wistar male rats associated with short-term Ca-concentration increase up to 4 mM has been studied. There has been found the parameter-relaxation index-the change of which under the effect of phenothiazines (10(-5) M in all the cases) made use of significantly correlates with the constants, which reflect the similarity of given agents with calmodulin.
