摘要: 目的: 考察口服和外用给药奥昔布宁在大鼠 体内的吸收和分布。方法: 48 只大鼠随机分为两 组:一组外用给予单剂 0.1 g 奥昔布宁自制凝胶 (2 mg OXY), 一组给予单剂 0.5 mg 普通片剂。 收集 血样 、膀胱和肝脏样本, 采用高效液相色谱-质谱法 测定奥昔布宁浓度。结果: 凝胶剂外用给药奥昔布 宁膀胱组织浓度为血浆的 800 倍, 而口服给药为 70 倍。 奥昔布宁凝胶剂半衰期延长为 5.99 h, 而口服 给药为 2.18 h。结论: 奥昔布宁凝胶剂半衰期延长, 作用部位膀胱组织浓度高, 与片剂相比具有明显的优势。

Abstract: AIM: To study the absorption and distri-bution characteristics of oxybutynin (OXY) oral tablet and transdermal gel.METHODS: A single dose of 0.1 g OXY transdermal gel (2mg OXY) was applied to abdom-inal area about 4 cm2 and 0.5mg immediate-release tablet was orally given to 48 rats in a randomized, open-label, control design test.The plasma, bladder and liver tissue were collected, disposed and analyzed and OXY pharma-cokinetic parameters were calculated and evaluated.RESULTS: The Cmax of OXY transdermal gel and oral table-ts in bladder are approximately 800 and 70 times higher than those in plasma.The plasma half life of OXY gel de-layed 5.99 h, tablets 2.18 h.CONCLUSION: OXY gel show better pharmacokinetic properties, characterized with long half life and high target organ concentrations than those of tablets.
