Mucoadhesive Buccal Patch Role in Emesis: Tweaked up by the Pivotal Permeation Enhancer: Sodium Lauryl Sulphate

Background: It has been observed that several diseases either acute or chronic have a specific symptom that is emesis. Emesis leads to depletion and removal of several salts and biological essentials required in the body. Domperidone is a D2 receptor antagonist, which triggers the chemoreceptor trigger zone (CTZ) and hence used in the management of nausea and vomiting. Objective: The objective of this project was to formulate a buccal patch of domperidone with the use of several polymers with a permeation enhancer. Since the oral bioavailability of domperidone is low due to gastric degradation, hence a buccal patch was prepared to determine its bioavailability. The purpose of this study was to formulate a buccal patch for better bioavailability and observe the effect of permeation enhancer with polymers. Methods: The mucoadhesive buccal patch was prepared using the solvent cast method. The characterization studies were done along with the drug content and compatibility studies through FTIR. Results: It was observed that the polymers; sodium carboxy methyl cellulose (SCMC) & polyvinyl alcohol(PVA) without sodium lauryl sulphate (SLS) had low drug release, which was around 68% and 72%, respectively whereas polymers with SLS had markedly increased drug release, which was around 89% and 91%, respectively. Conclusion: In order to obtain the maximum therapeutic efficacy of domperidone, buccal patches are considered much more beneficial than oral dosage form. Permeation enhancer also helps to synergize the effect of polymers which helps in better drug release and ultimately leads to better bioavailability.
