Omeprazole has been marketed in France since 1989, for the healing of peptic ulcers, erosive reflux esophagitis and the Zollinger Ellison syndrome. It is a proton pump inhibitor which inhibits the acid secretion in the stomach. In the majority of the clinical trials, omeprazole has been found to be well tolerated: headache, dizziness, skin rash, constipation have just been noted. Since September 1989, 143 adverse reactions have been reported to pharmacovigilance centres and Astra France: 37 neurological and psychiatric side effects, especially confusion in patients with hepatic diseases and/or advanced age; 35 cutaneous reactions, generally rash and urticaria; 22 hematological effects: leucopenia and agranulocytosis have been reported but the relation with omeprazole is very uncertain; 10 gastrointestinal effects, generally diarrhoea, nausea, vomiting and abdominal pain; 8 hepatic disorders, especially moderate elevation of aminotransferases. This study confirms the safety of this drug, during short treatment; the frequency of notified adverse effects is about 1/12 200 treatments of 4 weeks. The ministry of health, has decided, in november 1991, to inform the prescribers of this potential toxicity of omeprazole, particularly, of the risk of confusion, hepatotoxicity and leucopenia.

Patients with reflux esophagitis (grade II or III, Savary-Miller, intention-to-treat, n=256, age range 19-82 years) were randomly assigned to a double-blind, double-dummy treatment with either pantoprazole 40 mg once daily or ranitidine 150 mg twice daily. After 4 weeks, each patient was clinically and endoscopically assessed. Failure to heal required a further 4 weeks of treatment and a new evaluation thereafter. After 4 weeks, healing of lesions was confirmed in 63% (69 out of 109) of patients receiving pantoprazole and in 22% (25 out of 113) receiving ranitidine (P < 0.001, per protocol population). After 8 weeks, the cumulative healing rates were 88% and 46%, respectively (P < 0.001). Complete freedom from esophagitis-related symptoms (acid eructation, heartburn, pain while swallowing) was greater in the pantoprazole than in ranitidine group after 2 and 4 weeks (74% vs. 47%; 87% vs. 52%, respectively, P < 0.001). After 4 weeks, the healing rate was 76% in Helicobacter pylori (Hp)-positive vs. 45% in Hp-negative patients treated with pantoprazole (P < 0.01). The Hp status did not influence healing rates in patients treated with ranitidine. The most frequent adverse events in the pantoprazole group were diarrhea and somnolence (2-3% of patients), and in the ranitidine group, headache, diarrhea, dizziness, increase of liver enzymes and pruritus (2-4% of patients). In conclusion, pantoprazole was more effective than ranitidine in the healing rate and relief from reflux esophagitis-associated symptoms, and Hp infection was associated with higher healing rate during therapy with pantoprazole but not with ranitidine.

Common adverse effects of serotonin-norepinephrine reuptake inhibitors are nausea, dry mouth, dizziness and headache. We describe the case of a patient with dysosmia and subsequent dysgeusia associated with duloxetine. A 68-year-old Japanese woman with a history of type 1 diabetes mellitus, hypertension, insomnia and reflux esophagitis presented to a local hospital with bilateral leg pain; she was treated with duloxetine. However, after 4 weeks, she sensed rotten egg smell, experienced nausea and vomiting and was admitted to our hospital. We diagnosed dysosmia using the T&T olfactometer threshold test and dysgeusia using filter paper disk method. Taste was assessed using electrogustometry. We suspected that dysosmia and dysgeusia were adverse effects of duloxetine. After stopping duloxetine, her symptoms gradually subsided and the above test results improved, despite continuing the other ongoing medication. To the best of our knowledge, this is the first case report of dysosmia and dysgeusia associated with duloxetine.
