| Popis: | Introduction Isotretinoin is a synthetic vitamin A derivative, administered off-label as maintenance therapy for neuroblastoma. This report addresses the challenge of administering isotretinoin to children, given its availability as soft gelatin capsules only. Case report A 3-year-old boy diagnosed with stage IV neuroblastoma has undergone multimodal therapy, including six cycles of chemotherapy, followed by tumor resection and radiotherapy. Later, he was initiated on immunotherapy and prescribed isotretinoin 50 mg orally twice daily for two weeks, before each immunotherapy cycle. Isotretinoin is not available in liquid formulation and the patient could not swallow isotretinoin capsules. Therefore, pharmacist counseling was required to ensure appropriate administration of the drug. Management and outcomes The patient’s parents were instructed to pierce prescribed capsules, and empty and dilute their contents into a small glass containing olive oil after taking safety measures. Isotretinoin’s stability in olive oil for 72 h was compared using high-performance liquid chromatography to its stability in soybean oil. The recovery rates were 98.62% and 98.3%, respectively. Drug miscibility was not an issue as isotretinoin is lipophilic. Therefore, it could be administered easily without considerable remaining on the interior wall of the glass. Discussion To the best of our knowledge, this is the first report that suggests a practical method for administering isotretinoin in liquid form, particularly in pediatric oncology patients. Isotretinoin was noted to be stable in olive oil and its exposure to light and oxygen would not be an issue given the short time from preparation to administration and the low emphasis on exposure by the manufacturer when such a method is recommended. |
