For cancer therapy, microspheres can be used to increase effectiveness while decreasing side effects of treatments. We prepared gelatin microspheres containing carboplatin (GCPtM) for treating lung cancer. We prepared gelatin microspheres of carboplatin (GCPtM) for use in treating lung cancer. Microspheres were prepared using a Buchi B-90 nano spray-drier. Surface morphology was found to be shriveled to nearly spherical, with an average size of $14.7{\mu}m$. Drug loading and percentage yield were found to be $72{\pm}0.4$ and $88{\pm}0.2%$, respectively. In vitro release studies indicated that diffusion followed the Peppas model, with 99.3 % of total carboplatin released from GCPtM after 12 h, while for the pure drug this value was 92.4 % in 0.5 h. Liquification was observed during stability studies at $37^{\circ}C$ with an relative humidity of 75 %. Plasma concentration profile was described using a two-compartment model after intravenous injection of GCPtM. Carboplatin containing microspheres distributed in the lung, spleen, liver, and blood were found to be primarily distributed in the lungs. We used a powder technology (spray-dryer) method in this study to significantly reduce the overall production time and desired particle size, without using organic solvents; additionally, this method is economically feasible. Thus, microsphere may be an effective method for successfully delivering carboplatin to the lungs.
