ABSTRACT

Objective To study the effects of different enteric-coated aspirin tablets on upper gastrointestinal tract in the elderly. Methods 404 inpatients aged more than 65 years in last three years who took enteric-coated aspirin tablets (100mg/d) for more than three months were analyzed.They were divided into two groups bayaspirin-treated group (232 cases) and control group with ordinary enteric-coated aspirin tablet treatment (172 cases). The clinical data and the results of gastroseopy were compared between two groups, and the effects of two kinds of enteric-coated aspirin tablets on upper gastrointestinal tract in the elderly were analyzed by Chi-square test. Results The upper gastrointestinal bleeding rates were 20.3% in Bayaspirin-treated group (47/232) and 32.0% in control group (55/172), and there was significant difference between two groups(χ2=7.19,P<0.01)Gastroscopy indicated that gastroduodenal inflammation occurred in 16 patients (6.9% and peptic ulcer occurred in 8 patients (3.5%) in bayaspirin-treated group, while gastroduodenal inflammation occurred in 12 patients (7.0%) and peptic ulcer occurred in 36 patients(20.9%)in control group. The difference of the incidence of peptic ulcer between two groups had statistical significance(χ2= 31.10,P<0.01). The incidences of gastrointestinal adverse reactions were 8.6% (20/232) in bayaspirin-treated group and 23.3% (40/172) in control group, and there was a statistical difference between two groups. Conclusions Compared with ordinary enteric-coated aspirin tablet, bayaspirin has less adverse effects on upper gastrointestinal tract in the elderly and is more safe for treatment.
