ORAL WAFERS: A NOVEL APPROACH OF FAST DRUG DELIVERY

Oral fast disintegrating wafers are a relatively new type of dosage form. They are made thinly with water soluble polymers and quickly dissolve on the tongue or in the buccal cavity. Pharmaceutical technology research has advanced because to wafers' capacity to transport drugs for systemic action through the oral mucosa without causing hepatic metabolism disturbances. An overview of oral wafers, including their composition, classification, mechanism, formulation, evaluation factors, natural polymers that can be utilized to make wafers, and some previously developed antiemetic medication wafers are provided in this review study.
