RESUMO
Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a rare but severe and potentially life-threatening systemic clinical condition. We report a case of a 44-year-old female, who developed DRESS syndrome after taking two doses of aceclofenac, paracetamol, and thiocolchicoside fixed-dose combination. The patient presented with maculopapular rashes, itching, fever, pedal edema, swelling of the face and lips, difficulty in swallowing, loose stools, and vomiting for 4 days following drug intake. Laboratory and histopathological investigations supported the diagnosis following RegiSCAR criteria. The DRESS syndrome in this patient was definite as per Naranjo’s adverse drug reaction probability scale. The patient was adequately managed using systemic corticosteroids, antibiotics, and intravenous fluids. Aceclofenac is the most likely causative agent of DRESS syndrome in this patient. Early detection and withdrawal of the suspected drug along with adequate supportive treatment are the mainstay of management.
RESUMO
Prokinetic drugs like mosapride, domperidone etc, are used to treat gastrointestinal delay. Though the receptor-mediated actions of these agents have been studied, involvement of ion channels in reversing morphine-induced gastrointestinal inertia by prokinetic agents has not been explored. Charcoal meal test was used to measure small intestinal transit (SIT) in adult male Swiss albino mice. Animals were given ion channel modifiers and prokinetic drugs intragastrically. Reversal of morphine-induced gastrointestinal delay by mosapride was decreased significantly by CaCl2, minoxidil and glibenclamide. Similarly, domperidone's effect on morphine was decreased by CaCl2, nifedipine, minoxidil and glibenclamide significantly. The results reveal that ion channel modifiers counteract the prokinetic effects of mosapride or domperidone.
