Abstract
Solid lipid nanoparticles (SLNs) are introduced as an efficient carrier method for correcting dynamic medicine and water-soluble medication. Fexofenadine HCl is a long-acting selective histamine (H1) receptor antagonist with anti-inflammatory properties of the second generation. Allergic rhinitis, angioedema, and chronic urticaria are treated with fexofenadine HCl. Solid lipid nanoparticles were prepared by hot homogenization method using a solid lipid of and different polymers. A solid lipid nanoparticle created by drug and polymer poloxamer 188 in ratio showed highest entrapment efficiency as well as drug release of the medication from the solid lipid nanoparticle formulation. The prepared nanoparticles were used to formulate the nanogel using Carbopol 934. The nano-drug delivery system developed by the hot homogenization method has demonstrated their suitability for a topical route for the treatment of skin allergy. Thus, the studies revealed that the developed system has a great appeal for the convenient treatment of dermatological allergy that may overcome in improving the limitations of the existing drug delivery system. Fexofenadine HCl is a white colored powder. It is practically insoluble in water and soluble in methanol. The melting point was found to be 194.1-195.2. The FTIR spectra of Fexofenadine HCl and the mixture of drug and excipients used in the formulation of nanoparticles reveal that there was no significant interaction between the drug and polymer and other excipients used in the formulation. The optimized batches (F2) showed highest entrapment efficiency. It was observed that as there is increase in concentration of surfactant increases the entrapment efficiency. The optimized solid lipid nanoparticle formulation showed maximum drug release within 6 hr. This showed that the increase in the concentration of surfactant there was increase in drug release from the SLN.
