Paclitaxel (PTX) is a lipophilic agent with broad anticancer activity. In the present study we examined the antitumor effect and toxicity of co-administration of cyclosporine A (CsA) and PTX in liposomal aerosol using the Renca lung metastases mouse model. The untreated and PTX-only groups exhibited cancer growth while CsA aerosol plus PTX had more favorable effects on tumor growth. Weight loss was seen in mice treated with CsA/PTX+CsA by day 9 to 22. Histopathological examination showed no toxicity following treatment. The findings offer evidence that a combination of CsA and PTX may be suitable for aerosol treatment of lung cancer if it is possible to control toxicity of the therapy.
