In view of the pharmacodynamic and therapeutic properties of a broad-spectrum semisynthetic penicillin recently introduced in Italy, namely sulbenicillin, the authors conducted a multicentre clinical and bacteriological trial of the drug administered by intramuscular or intravenous injection in daily doses of 4, 6 or 8 g given in two or three administrations daily to a group of 66 patients with acute bronchopulmonary infection, mainly exacerbation of chronic infection, hospitalized in four Pneumology Centres of Sardinia. The authors assessed clinical, radiological, microbiological, and biohumoral parameters before and after treatment to provide a basis for assessing test product effectiveness and tolerability. On the strength of their findings, the authors concluded that the clinical and bacteriological activity of sulbenicillin was satisfactory and its local and general tolerability was excellent. The assembled findings indicate that the new antibiotic molecule can be used to advantage in the treatment of nontubercular bronchopulmonary infections, including severe or otherwise "difficult" cases, providing that the drug is administered at adequate dosages and for sufficiently long treatment periods.

A double-blind, multi-centre trial was carried out in 72 patients with acute or chronic infections of the lower respiratory tract to compare the efficacy and tolerance of a sulfamethopyrazine (200 mg)/trimethoprim (250 mg) combination with that of the established combination co-trimoxazole (400 mg sulphamethoxazole plus 80 mg trimethoprim). Patients received treatment for 10 days either with 2 capsules of co-trimoxazole twice daily or in the newer combination group with 2 capsules on Day 1 but then only 1 capsule daily for the remainder of the treatment period. The results of clinical, bacteriological and functional tests showed an excellent or good response in over 90% of patients in each group. There was no statistically significant difference in effectiveness of treatment with the once-daily sulfamethopyrazine/trimethoprim regime compared with co-trimoxazole given twice daily, and both treatments were well tolerated, with only a few mild side-effects, mainly gastro-intestinal ones, being reported.
