AbstractThis was a double-blind randomized study to compare the safety and efficacy of timethoprim-polymyxin B (TP) and trimethoprim-sulfacetamide-polymyxin B (TSP) drops in the treatment of otorrhea. The 68 cases treated suffered from external otitis, recurrent otitis, recurrent otitis media with tympanic membrance perforation, or infected mastoid cavities and post-operative tympanoplasties. The TP ototopical solution was successful in 60·6 per cent of cases compared to 88·6 per cent of cases with TSP. These rates were statistically different using the Chi Square with Yates' correction method.There were no sings of ototoxicity, fungal infection overgrowth or local sensitivity to either of the solutions.The study has shown that both drugs are equally safe and that TSP is significantly more effective in the treatment of otorrhea.

Cutaneous Reactivity

In a double-blind study performed in 81 healthy volunteers, 10 mg cetirizine and 60 mg terfenadine given orally in a single administration significantly inhibited skin reactivity to histamine. Astemizole (10 mg) was completely ineffective. The inhibitory effect of cetirizine was potent and regular whereas 6/28 (21%) volunteers did not respond to terfenadine. The difference observed beween cetirizine and terfenadine might be due to differences in the metabolism of the two drugs after administration: terfenadine is rapidly and extensively metabolized whereas cetirizine is directly active without the need for biotransformation and, indeed is poorly metabolized.
