Flavored Nanofiber Strips Loaded with Amoxicillin as an Alternative Method for Treating Bacterial Infections in Children
Semisynthetic penicillin, Amoxicillin, is a broad-spectrum antibiotic that is widely used to treat bacterial infections in children suffering ear, nose, and throat infections, genitourinary tract infections, skin infections, and lower respiratory tract infections1. This antibiotic works against both gram-positive and gram-negative bacteria, such as Listeria monocytogenes, Haemophilus influenza, Streptococcus pneumonia , Streptococcus pyogene and Escherichia coli1,2. It shows antibacterial activity by inhibiting dd-transpeptidase, which maintains the integrity of the bacterial cell wall which results in bacterial cell death due to a fragile cell wall3. Nonadherence to medication was associated with 50% of drug-related hospitalizations in children4. In order to improve adherence and influence clinical outcome, it is important to acknowledge the importance of drug palatability to children4–6. The currently available liquid suspension form of this antibiotic is administered to patients through oral/GI routes. It is also available in capsules or tablets for adults7–9. In the gastrointestinal tract, the drug has to withstand variable pH conditions and enzymatic degradation , mucus and mucosal barriers to survive resulting in limiting drug bioavailability10,11. In addition to conventional drug delivery formulations, nanofibers can be used to deliver drugs orally, topically, and through buccal or transdermal routes12. Drug-loaded nanofibers offer many advantages as a delivery system, including their porous structure and their efficient delivery of various drugs and bioactive molecules including hydrophobic and hydrophilic drugs12–14. Considering that amoxicillin palatability can affect children patients’ compliance and due to the advantages of both nanofiber drug delivery system and drug delivery through buccal routes, hence, this project aims to prepare flavored electrospun nanofibers loaded with amoxicillin to mask the unpleasant taste of the drug for treating children with bacterial infection. Nanofibers loaded with amoxicillin can be applied between the child's gum and cheek, allowing the fibers to dissolve in mucus and penetrate directly into the bloodstream.
