Myoactin C, which was used for alveolar pyorrhea, is composed of ATP, L-tyrosine and L-cysteine, as fix combination drugs.
The author observed that ATP increased the tone of smooth muscle at a low concentration, and decreased it as a high concentration on the mechanical activity of the smooth muscle (portal vein), but the effects of Myoactin C on the smooth muscle can be considered that they relate closely with L-tyrosine, +L-cysteine, +ketoglutaric acid.
