Derivatives of N-phenylbenzamide with general formula (1) in which R.sub.1 is a cyano, nitro, halogen, hydrozy, C.sub.1 -C.sub.4 alkyl methyl, methoxy or tetrazol-5-yl group, R.sub.2 is hydrogen, hydroxy, or methoxy, R.sub.3 is a tetrazol-5-yl group or hydrogen, R.sub.4 and R.sub.5 are hydrogen if R.sub.3 is tetrazolyl but are independently selected from the group consisting of carboxy, methoxycarbonyl, ethoxycarbonyl and carbamoyl if R.sub.3 is hydrogen, and R.sub.6 is hydrogen or methyl. The derivatives have an anti-ulcer and anti-allergy activity.
