Abstract

A lot of polymeric oral dosage forms have been invented for suitable drug delivery and compliance of patient. Oral dissolving film (ODF) offers a comfortable way to enable drug administration. The purpose of this study was to develop an ODF using lidocaine, with moderate mechanical strength and thickness, fast disintegration time and local anesthetic effect. Hydroxypropyl methyl cellulose, sodium alginate, glycerin, sodium lauryl sulfate, polyvinylpyrrolidone and citric acid were used to build the polymeric film base of the ODF. The optimal composition was determined by changing the ratio of individual excipients. The thickness was insignificantly varied in the range of 0.04?±?0.01 to 0.06?±?0.01 mm. On the other hand, the tensile strength was 1.23?±?0.20 to 1.83?±?0.30 N/cm2. Drug content in the films was evaluated and the values were 16 mg of lidocaine per each ODF (40 mg/strip). Lidocaine ODF formulation showed the release of 91.7% of lidocaine within 1 min and 96.3% of lidocaine in 5 min. These results suggested that lidocaine ODF was well prepared and showed the fast release of lidocaine.
