Trinalin is a combined preparation, which comprises: non-narcotic analgesic metamizol sodium, myotropic antispasmodic pitofenon and m-anticholinergic remedy fenpiverinia bromide.
Metamizole sodium possesses analgesic, antipyretic and weak anti-inflammatory action. Pitofenon, similar to papaverine, has a direct myotropic effect on smooth muscles of internal organs and causes its relaxation. Fenpiverinia bromide through m-holinoblokirutego action has an additional spasmolytic effect in relation to smooth muscle.
The combination of the three components of a preparation leads to mutual strengthening of their pharmacological action.
Absorbed quickly; after intramuscular injection largely absorbed from the injection site.
Relationship with blood plasma proteins is 50 – 60 %. At therapeutic doses is excreted in breast milk.
Metamizole sodium under intense biotransformation in the liver. Only after intravenous administration minor concentration of unchanged sodium metamizol detected in plasma. The main metabolites are 4-methylaminopterin, 4-formalininactivated, 4-amino-antipyrine and 4-acetylaminofluorene. Identified about 20 additional compounds including derivatives of glucuronic acid. Four main metabolite detected in cerebrospinal fluid.
Write mainly kidneys.
Pitofenon and fenpiverinia bromide characterized by incomplete resorption, however, they are completely ionizerthe. Have a weak laboratoriesthe. Do not pass through the blood-brain barrier.
Metabolised in the liver by oxidative reactions.
Pitofenon excreted by the kidneys. Maximum plasma concentration is reached within 30 – 60 min elimination half-life is 1.8 hours.
Fenpiverinia bromide excreted by the kidneys of 32.4 – 40.4% of the unchanged, in the bile excreted 2,5 – 5,3% of the substance.
