We report a patient who developed a fixed drug eruption (FDE) due to sulfaguanidine. This drug has not been previously implicated as a cause of FDE. The diagnosis was confirmed by an oral provocation and a biopsy of the lesion.

Sulfonamides (SAs) are one of the oldest groups of veterinary chemotherapeutic agents. As these compounds are not completely metabolized in animals, a high proportion of the native form is excreted in feces and urine. They are therefore released either directly

The host-guest inclusion complexes of sulphamethoxazole (SMTX) and sulphaguanidine (SGN) with beta-cyclodextrin, in aqueous solutions, have been investigated. A 1:1 stoichiometry of the complexes was established, the association constants were calculated by different methods, and the influence of several chemical

Microspheres were formed when a solution of cellulose phthalate was extruded into 30% glacial acetic acid solution. Sulphonamides entrapped in such microspheres leached into the hardening solution because they dissolved freely in the acetic acid solution. This resulted in poor

Two electrically neutral analytes previously observed to be separated from the neutral marker in capillary zone electrophoresis (CZE) experiments [sulphanilamide (SAA) and sulphaguanidine (SGW)] have been examined to determine the basis for separation. The degree of separation increases markedly with
