Abstract
The challenge in the formulation of novel systems for TDDS is to identify technologies and formulation excipients which simultaneously optimize drug permeation. Our main goal was to design and evaluate a recent alternative for the administration of tramadol HCl. Performed the preformulation study as different evaluation parameters Physiochemical Studies, Solubility Determination, Partition Coefficient, and Preparation of Calibration Curve simultaneously Preparation & Characterization of Hydrogel Formulation Homogeneity, pH Measurement, Drug Content, Viscosity, Spreadability, In-Vitro Permeation, FT-IR Studies. Results revealed that the present investigation, tramadol was successfully incorporated into different gel formulations. Among all gel formulations, tramadol gel (F13) proved to be the formula of choice, showing good characteristics and controlling the drug release for long period of time. Gel formulation F13 could be very promising and innovative topical alternative for pain management and arthritis and play a vital role in drug efficiency. These findings may open new avenues for the treatment through dermal by local application of tailored gel. However, further preclinical and clinical studies are recommended to support its efficiency claims in humans.
