Combinatorial therapeutic approach for treatment of oral squamous cell carcinoma

Oral squamous cell carcinoma (OSCC) is one of the common type of cancer in humans. A combinatorial approach has been done by using paclitaxel (PTX), 5-fluorouracil (5-FU) and ascorbic acid (AA) loaded solid lipid nanoparticles (SLN) for its treatment. SLN were made by high-speed homogenization and ultrasonication technique and they were used alone and in combination to check their efficacy against OSCC induced animal model. Pharmacokinetics and biodistribution study of the optimized formulations for PTX, 5-FU and AA loaded SLN was performed. The SLN shows a biphasic nature of drug release both in the in-vitro and in-vivo system. SLN loaded with PTX in combination with SLN loaded with AA shows a greater potency in the treatment of OSCC in-vivo. The Pharmacokinetic and biodistribution studies of SLN depict a better therapeutic efficacy. The combination of PTX and AA loaded SLN can be a novel approach for the treatment of OSCC.
