Most of anti-tuberculosis drugs are hepatic toxicity; especially 3 most common and best efficient drugs R, H, Z. Drug combination resulted in increasing toxicity, adverse events, especially drug-induced hepatitis. The authors reviewed situation of drug-induced hepatitis in the world and introduced one case in Vietnam. He also listed some drug known that have hepatotoxicity such as isoniazid (INH, H); rifampicin (RMP, R); pyrazinamid (PZA, Z); ethambutol (EMB, E); ethionamid (ETB); thiacetazon (TH, Tbl) and their mechanisms.

Chronical obstructive pulmonary disease (COPD), bronchus asthma and pneumonia are 3 common causes of death. Among them COPD is the leading cause of morbidity and mortality in Europa, the 4th leading cause in North America. Currently, there are 3 main groups of largely used medicaments beta 2 agonist, anticholin and methylxxanthin. With diverse pharmacological characteristics, all 3 groups also dilate the bronchus, change the diameter of air channel and the dilative pressure of the lung. They impact on the respiratory tract by 2 mechanisms: directly on the smooth muscle cell of the tract and inhibite the bronchus contraction neurologically. The mechanism and the level of their effects are differented in the treatment of bronchus asthma and COPD, in depending on each subject
