Background: Glioblastomas arise from multistep tumorigenesis of the glial cells. Despite the current state‐of‐art treatment, tumor recurrence is inevitable. Among the innovations blooming up against glioblastoma, drug repurposing could provide profound premises for treatment enhancement. While considering this strategy, the efficacy of the repurposed drugs as monotherapies were not up to par; hence, the focus has now shifted to investigate the multidrug combinations. Aim: To investigate the efficacy of a quadruple‐combinatorial treatment comprising temozolomide along with chloroquine, naringenin, and phloroglucinol in an orthotopic glioma‐induced xenograft model. Methods: Antiproliferative effect of the drugs was assessed by immunostaining. The expression profiles of WNT/β‐catenin and apoptotic markers were evaluated by qRT‐PCR, immunoblotting, and ELISA. Patterns of mitochondrial depolarization was determined by flow cytometry. TUNEL assay was performed to affirm apoptosis induction. In vivo drug detection study was carried out by ESI‐Q‐TOF MS analysis. Results: The quadruple‐drug treatment had significantly hampered glioma proliferation and had induced apoptosis by modulating the WNT/β‐catenin signaling. Interestingly, the induction of apoptosis was associated with mitochondrial depolarization. The quadruple‐drug cocktail had breached the blood–brain barrier and was detected in the brain tissue and plasma samples. Conclusion: The quadruple‐drug combination served as a promising adjuvant therapy to combat glioblastoma lethality in vivo and can be probed for translation from bench to bedside.
