Topicality. It is known that anti-tuberculosis (TB) drugs is hapatotoxic. Treatment of patients with tuberculosis involves the use of anti-TB drugs (4-6) complex at the same time, which causes the development of severe toxic hepatitis. Severe toxic hepatitis occurs during the treatment of first-line drugs in 60 % of patients and 42.4 % when used of second-line drugs. In 10-28 % of patients the development of severe hepatitis requires the abolition of anti-TB chemotherapy. The existing conditions require the search and creation of new herbal drugs for the prevention and treatment of hepatitis caused by drugs
Aim. To evaluate the effectiveness of a new complex herbal medicine (CHM) “Hepatropin” in the form of granules in the experimental hepatitis conditions caused by tuberculostatic drugs.
Materials and methods. Study of hepatoprotective activity of a new CHM, “Hepatropin” granules (intragastrically 900 mg/kg once a day) on a model of hepatitis caused by intragastric administration of tuberculostatics mixture (Isoniazid 50 mg/kg, Rifampin 500 mg/kg, Pyrazynamide 1500 mg/kg) in the form of aqueous suspension for 14 days, in comparison with a reference medicine containing extracts of Fumaria officinalis and Silybum marianum fruits (intragastrically 35 mg/kg once a day). To assess the general condition of the animals, their survival was assessed; for the assessment of the functional state of the liver, the activity of the enzymes alanine aminotransferase (AlAT), alkaline phosphatase (APh), liver mass coefficient (LMC) were determined in the serum. The processes intensity of lipid peroxidation (LPO) and the antioxidant system activity (AAS) was evaluated in accordance with the TBA-active products level (TBA-AP), reduced glutathione (RG) in serum and the activity of the antioxidative enzyme catalase in the liver homogenate. The state of lipid metabolism was assessed by the cholesterol level and total lipids in serum.
Results and discussions. Granules “Hepatropin” contributed to a decrease in LMC from 4.02 % to 3.66 % and alkaline phosphatase activity 1.4 times, AlAT 1.6 times in serum, TBA-AP 1.4 times, increased level of RG in the homogenate liver and catalase in the blood serum, respectively, 1.7 and 1.9 times, as well as a decrease in the level of total lipids and cholesterol in the blood serum, respectively, 2.2 and 3.6 times relative to similar indicators in untreated animals.
Conclusions. The hepatoprotective effect of the herbal medicine “Hepatropin” has been established. The severity of normalizing effect on the disturbed lipids level in the serum, pro- and antioxidant balance. According to indicators, the drug “Hepatropin” exceeded the effect of the reference drug. The presence of a pronounced hepatoprotective action justifies the further expediency study with the aim of practical “Hepatropin” agent application for the correction of the hepatotoxic effects of anti-tuberculosis drugs.
