N-alkyl-4'-hydroxyacetanilides wherein alkyl is of up to 8 carbon atoms, preferably ethyl or isopropyl, have analgesic, antipyretic, anti-inflammatory and sedative activity. Those of at least two carbon atoms lack the hepatotoxicity of acetaminophen and the N-methyl compound also has substantially less hepatotoxicity than acetaminophen. Pharmaceutical compositions comprising them are employed to ameliorate pain, reduce fever, reduce the symptoms of systemic inflammatory conditions and sedate.
N-烷基-4'-羟基乙酰苯胺,其中烷基含有不超过8个碳原子,优选乙基或异丙基,具有镇痛、退热、抗炎和镇静活性。至少含有两个碳原子的化合物不具有对乙酰氨基酚的肝毒性,而N-甲基化合物的肝毒性也显著低于乙酰氨基酚。包含它们的制药组合物用于缓解疼痛、降低发热、减轻全身炎症症状并镇静。
