Antiviral Application of Carbohydrate Polymers: A Review

Viral disease is a well-known cause of a significant impact on economic losses and threatens developed and developing societies. High mutation rates and the lack of ability of conventional formulations to target specific cells pose substantial hurdles to the successful treatment of viral diseases. We conducted a preliminary search by a standard procedure. With hand searching, we conducted an advanced search across several electronic databases. After defining the selection criteria, two writers independently reviewed and evaluated the first 500 abstracts before screening the remaining 300. Since there was 97% agreement on the screening decisions, only one reviewer conducted the screening. The pre-planned data extraction process was accomplished, and the thoroughness of the description of participation techniques was assessed. Additional data extraction was carried out for articles with the most detailed illustrations. Four stakeholder representatives co-authored this systematic review. Incorporating selective carbohydrate polymers into the antiviral pharmaceutical compositions could help to manage biological complications associated with viral infections. We included 172 papers in which authors were involved in a systematic review. The present review explains the role of carbohydrate polymers (chitosan, carrageenan, alginate, cyclodextrin, dextran, and heparin) in the prevention and treatment of viral infections in terms of their source, molecular weight, surface charge, chemical composition, and structure. Additionally, the review describes the primary mechanism of drug delivery performance of carbohydrate polymers to improve the antiviral properties and pharmacokinetic behaviour of lamivudine, zidovudine, acyclovir, etc. The article discussed the role of carbohydrate polymers in mitigating virus-induced associated complications like bacterial infection, cardiovascular disorder, oxidative stress, and metabolic disorder. As a result, this work will provide valuable information to scientists, researchers, and clinicians for suitable carbohydrate polymer-based pharmaceutical development.
