To evaluate the pharmaceutical aspects of solvent deposition method where drug is solvent deposited on the surface of excipients, a study has been made on dissolution characteristics of indomethacin solvent deposited on lactose and potato starch. In a solvent deposition system, the drug-to-excipient ratio and kind of excipient effect much on dissolution rates of indomethacin. The experimental results are as follows: 1) Lactose was shown to be superior to potato starch as excipients in indomethacin solvent deposited. 2) Total amount of indomethacin dissolved from solvent deposition systems at 30 minutes were enhanced about 5 to 23 times compared with that of pure indomethacin. 3) Increased dissotion amount of indomethacin from the solvent deposition systems were observed to be alike in the systems where the drug-to-excipient weight ratios were 1 : 5, 1 : 7 and 1 : 10.
