[Clinical trials with amoxicillin (Pasetocin 'Kyowa') on infections of respiratory apparatus (author's transl)].

Amoxicillin at a daily dose of 1-1.5 g was orally administered to total 30 cases comprising 6 of acute tonsillitis, 6 of chronic tonsillitis, 8 of acute bronchitis, 4 of chronic bronchitis, 4 of bronchiectasis, 1 of suppurative diseases of the lung and 1 of exudative pleurisy. The clinical results and side effects are reported. 1. The effect of amoxicillin was remarkably good in 15 of 30 cases with infections of respiratory apparatus (50%), good in 7(23%), poor in 5(17%) and unknown in 3(10%); the effectiveness was 73%. 2. In terms of diseases, amoxicillin was effective in 33% of acute tonsillitis, in 50% of chronic tonsillitis and in all of acute bronchitis, chronic bronchitis, bronchiectasia and suppurative disease of the lung. No effect was observed in exudative pleurisy. 3. In terms of strains detected, amoxicillin was effective in 67% of Staphylococcus aureus, in 89% of Haemophilus and in 50% of Klebsiella. This drug was effective in all cases caused by Escherichia coli, Acinetobacter calcoacetines, beta-Streptococcus, Flavobacterium, Streptococcus pneumonia, though these strains were not frequently detected. Pseudomonas aeruginosa had no response to this drug. 4. Two cases of transient hepatic dysfunction, 6 of eruption, 5 of gastro-intestinal disorders, 1 of arthralgia and 1 of pyrexia were observed as side effects (some cases had side effects in overlap).
