Formulation and stability study of chlorpheniramine maleate nasal gel.
Nasal administration has been of special interest in the last decade due to its feasibility and relative high bioavailability compared to the oral rout of administration. Our study aimed to develop a nasal gel formulation for an antihistaminic drug, Chlorpheniramine maleate (CPM), which suffers from poor oral bioavailability (25-45%) due to its first-pass metabolism in the liver. Different formulations of CPM nasal gels were prepared using different polymers in different concentrations, these gels were evaluated for their in vitro (physico-chemical properties, release, permeability and stability) to select the best formulation which subject to in vivo tests including mucociliary clearance and bioavailability, both in comparison to the solution and commercial tablet Allergyl.
