Formulation and In-vitro Evaluation of Tramadol Hydrochloride Gel
Keywords:
Tramadol hydrochloride, Gel, Xanthan gum, carbopol, Permeabilty studyAbstract
Tramadol is an opioid analgesic. The most common side effects with opioid analgesics are nausea and vomiting (particularly at the start of treatment), constipation, and dry mouth. Opioids can also cause drowsiness and confusion. Due to the adverse drug reactions associated with oral formulations opioid analgesics can be administered by topical route. Gelling agents like xanthan gum, carbopol are used in the formulation of Tramadol hydrochloride gel. In vitro permeability studies using a semipermeable membrane was carried out to find the optimized formulation
