[Ampicillin in high doses in bronchopneumopathies in aged patients]

Ampicillin at 2-4 g/day per os and 2 g/12 hr slow venous drip gave good results in 88% of 25 and 90% of 20 cases of bronchopneumopathy respectively. Tolerance was excellent in all but 4 cases. In spite of the introduction of new semi-synthetic penicillins, it is felt that ampicillin must still be rated as one of the most effective and best tolerated antibiotics. At the doses at present recommended, it is of particular significance in the treatment of aged subjects.
