Depending on the site of irradiation, about 40-80% of patients undergoing radiotherapy (RT) will experience nausea and/or vomiting. The current study aimed to investigate the efficacy of ondansetronas as a single agent and with a combination to aprepitant on preventing RT-induced nausea and vomiting (RINV). ⋯ The present study indicated a significant superiority of combination of ondansetron and aprepitant in management of RINV, in patients undergoing RT, compared to ondansetron as a single agent therapy. More accurate follow-up studies are needed for the evaluation of the efficacy of ondansetron with combination to aprepitant on preventing the RINV.

New formulations and technologies have been developed through oral drug delivery systems' researches. Such researches display significance of oral route amongst patients. We've reviewed all the features associated with medicated chewing gum as a modern drug delivery by introducing the history, advantages and disadvantages, methods of manufacturing, composition differences, evaluation tests and examples of varieties of medicated chewing gums. ⋯ Potential applications of medicated chewing gums are highly widespread as they will be recognized in future. Nowadays standards for qualifying chewing gums are the same as tablets. Patient-centered studies include medicated chewing gums as a delivery system too which creates compliance for patients.

Incomplete efficiency of oral medications restricts their therapeutic success in pain control of the painful form of the diabetic peripheral neuropathy (DPN). Use of topical medications because of less systemic side effects is more acceptable. This study aimed to compare the effect of clonidine gel and capsaicin cream in relieving pain associated with DPN. ⋯ The results of this study showed the comparable efficacy of clonidine gel in comparison with capsaicin cream in the treatment of pain due to DPN with less adverse events. More studies are required to better evaluate the efficacy and safety of this topical compound for relieving pain in DPN.
