盐酸坦索罗辛缓释制剂的研究进展

Progress of tamsulosin hydrochloride sustained-release preparation

盐酸坦索罗辛广泛用于治疗良性前列腺增生症的下尿路症状，需要长期用药。口服盐酸坦索罗辛因药物吸收快、起效快，常导致低血压和眩晕等不良反应，故临床上建议应用其缓释制剂。目前国内外上市的盐酸坦索罗辛缓释制剂主要为缓释胶囊和缓释片，如Flomax^（R），Harnal^（R），国内仍以原研制剂Harnal^（R）缓释胶囊占有主要市场，鉴于该药良好的市场前景，对其缓释制剂的研究也越来越多。本文就盐酸坦索罗辛缓释制剂的研究进展做一综述。
