In this study, we investigated the effect of histamin H2 receptor antagonist (H2RA) or proton pump inhibitor (PPI) for the prevention of upper gastrointestinal lesions associated with low-dose aspirin. We carried out a retrospective study of 2811 patients who had been prescribed low-dose aspirin (Bayaspirin® 100 mg) for more than 30 days at Tokai University Hachioji Hospital from 2006 to 2008. We classified them into three groups: aspirin alone group (n=1103), aspirin with H2RA group (n=844) and aspirin with PPI group (n=864). Patients who developed upper gastrointestinal lesions were diagnosed with gastric ulcer, duodenal ulcer, gastritis or duodenitis by gastroscopy. We then compared the incidence of upper gastrointestinal lesions among the groups. The incidence in aspirin alone group, aspirin with H2RA group and aspirin with PPI group was 2.54%, 1.54% and 1.04%, respectively; that of aspirin with PPI group being significantly lower (p<0.05). Additively, the odds ratio (OR) of aspirin with H2RA group and aspirin with PPI group was 0.60 (95% confidence interval [95%CI]: 0.31-1.17) and 0.40 (95% CI: 0.19-0.86) as compared with aspirin alone group, respectively. The upper gastrointestinal lesions were developed within two years in all groups. Our results suggest that the combined administration of low-dose aspirin and PPI is effective for the prevention of upper gastrointestinal lesions associated with low-dose aspirin. Also, the pharmacists should be especially careful for upper gastrointestinal lesions development within two years after administration of low-dose aspirin, regardless of combined whether H2RA or PPI.

Low-dose aspirin-induced gastrointestinal lesions are becoming an important problem in clinical practice. In our investigation of such adverse effects, we obtained 4 important findings considered useful for physicians, as follows; 1) even when aspirin was given at a dose, the incidence rate of gastrointestinal lesions was higher than with other NSAIDs, 2) the odds ratios for gastrointestinal lesions induced by aspirin with a histamine H2 receptor antagonist and proton pump inhibitor were 0.6 and 0.4, respectively, as compared with aspirin alone, 3) it is difficult to administer aspirin, which exerts an antiplatelet effect, without inducing gastrointestinal lesions, and 4) these gastrointestinal lesions appears early, especially within 2 years after administration. We distributed a questionnaire to 41 physicians to confirm our findings, and compared high (n=20) and low (n=21) frequency aspirin prescription groups. The recognition rate of points 1 and 3 noted above in the high group was significantly elevated as compared to the low group, whereas there no significant difference in regard to the information in point 4 between the groups and the rate of recognition was low. Moreover, only 27% of the surveyed physicians were familiar with all 4 points. Prior to receiving this information, 17% of the physicians gave no related instructions their patients, which was reduced to 0% after receiving this information. Furthermore, 98% of those surveyed found the information to be useful. Our results suggest that these 4 points of information regarding potential adverse gastrointestinal effects of low-dose aspirin are useful for physicians.

The effect of mouth wash on the removal of drug residues in both mouth and pharynx after the use of fluticasone propionate dry powder inhaler (FP-DPI) was studied. The concentration of FP in mouth wash after sprinkle and inhalation of Flutide® 50, 100, 200 Rotadisk® was determined by HPLC-UV. The total amount of the removed FP was measured by the sum of the concentration of FP in 5 times of mouth washes. The mouth wash procedures removed totally 79.3±4.4% (50 μg), 68.5±3.6% (100 μg), 69.3±3.4% (200 μg) of sprinkled amount of FP and 29.5±11.1% (50 μg), 35.6±6.6% (100 μg), 31.6±8.3% (200 μg) of inhaled, respectively. It was required for the removal of 90% of the totally recovered FP to do two times of mouth washes in each case. These data suggest that the mouth wash is an effective precaution for candidiasis induced by FP delivered by DPI.

We evaluated the effectiveness of small group discussion (SGD) in association with a drug abuse prevention program for junior high school students. The students first received a lecture about drug abuse prevention, then participated in SGD. The discussion focused on how to take action when tempted to abuse drugs. We gave a questionnaire 3 times; before and after the lecture (before SGD), and after SGD. Seventy-seven students replied to these questionnaires. After the lecture, knowledge about drug abuse was improved and all students answered that they had never abused drugs. However, in answer to a different question, a few students noted that they might use drugs in some situations. We consider it necessary to give more consideration to this problem. After the lecture, 35.5% of the students felt that they had definitely acquired skills for drug abuse prevention, whereas after the SGD this was increased to 73.7%. In addition, more than 75% of the students answered that the SGD program was useful since the opinions of other students could be heard. These results suggest that more students acquired skills to prevent drug abuse by participation in SGD. Our findings showed that SGD was useful and that the students were able to more effectively understand important concepts related to drug abuse prevention.
