毒理性
水杨酸盐中毒可能在摄入或局部应用甲基水杨酸后发生。轻微的慢性水杨酸盐中毒,也称为水杨酸症,通常仅在重复使用大剂量后才发生。水杨酸症还可能在水杨酸盐过度局部应用后发生。毒性症状包括头晕、耳鸣、耳聋、出汗、恶心和呕吐、头痛和混乱,可以通过减少剂量来控制[F91]。更严重的中毒或急性过量中毒的症状包括过度换气、发热、不安、酮症、呼吸性碱中毒和代谢性酸中毒。中枢神经系统的抑制可能导致昏迷,还可能导致心血管崩溃和呼吸衰竭[F91]。
Salicylate intoxication may occur after ingestion or topical application of menthyl salicylate. Mild chronic salicylate intoxication, also known as _salicylism_, normally occurs only after repeated use of large doses. Salicylism can also occur following the excessive topical application of salicylates. Symptoms of toxicity include dizziness, tinnitus, deafness, sweating, nausea and vomiting, headache, and confusion, and may be controlled by reducing the dosage [F91]. Symptoms of more severe intoxication or of acute poisoning following overdose include hyperventilation, fever, restlessness, ketosis, and respiratory alkalosis and metabolic acidosis. Depression of the CNS may lead to coma, cardiovascular collapse and respiratory failure may also result [F91].
