The metabolism of salicylic acid is by glycine and phenolic or acyl glucuronate conjugation with small amounts of the drug undergoing hydroxylation [L2139]. Extensively metabolized in the liver; inactive metabolites are excreted by the kidneys [L2142].
LD50, oral in mouse: 2690mg/kg [L2125]. Ld50, subcutaneous in mouse: 1gm/kg [L2125]. Interferes with thyroid function test [L2132]. Gastrointestinal (GI) disorders, fatigue, hypersensitivity reactions, skin eruptions, hemolytic anemia, weakness, dyspnoea; local irritation (rectally); Reye's syndrome. **Potentially Fatal:** Paroxysmal bronchospasm; hepatotoxicity; renal impairment/failure; thrombocytopenia, iron-deficiency anemia, occult bleeding, leukopenia; mild chronic salicylate intoxication [L2132]. Salicylate poisoning is normally associated with plasma concentrations >350 mg/L (2.5 mmol/L). Most adult deaths due to salicylate poisoning occur in patients whose serum concentrations of salicylate are over 700 mg/L (5.1 mmol/L). Single doses of less than 100 mg/kg are very unlikely to lead to serious poisoning. Patients should be provided with supportive therapy or treatment for salicylate poisoning as necessary. This may include treatment like activated charcoal, urinary alkalinization and, in severe cases, hemodialysis [L2139].

吸收、分配和排泄
吸收
开始时间:摄入后1-2小时 [L2133] 口服形式下,水杨酸胆碱通过颊粘膜被吸收。需要谨慎不要超过规定的剂量,并监测任何建议的水杨酸盐中毒迹象,尤其是在给婴儿使用此药物时 [L2135]。在一项研究中,发现这种药物的吸收速度比阿司匹林(ASA)更快(吸收半衰期=0.1 vs 0.36小时)[L2138]。
Onset: 1-2 hr after ingestion [L2133] In the oral form, choline salicylate is absorbed across the buccal mucosa. There is a need for caution not to exceed the stated dose and monitor for any signs of suggested salicylism, especially when this drug is used for infants [L2135]. In one study, it was found that this drug was more rapidly absorbed than ASA (absorption t1/2 = 0.1 vs 0.36 h) [L2138].

消除途径
乙酰水杨酸胆碱的两种代谢物以及少量完整的水杨酸会被排出,主要是通过尿液。
Both metabolites of choline salicylate, and a small amount of intact salicylic acid are excreted, primarily in the urine [L1239].

The invention relates to a drug conjugate including a drug and a plant steroid. The drug conjugate may target the drug for intestinal cell delivery, and thus may be used to treat diseases, including intestinal diseases, or to affect intestinal metabolism. The invention therefore also relates to treating intestinal diseases and affecting intestinal metabolism with the drug conjugate.
Described herein are compounds and pharmaceutical compositions containing such compounds, which modulate the activity of store-operated calcium (SOC) channels. Also described herein are methods of using such SOC channel modulators, alone and in combination with other compounds, for treating diseases or conditions that would benefit from inhibition of SOC channel activity.
