Introduction The management of wound remains a challenge in spite of the progress created so far in the development of wound dressing materials as well as the amount of expert discipline or experience in the field of wound management. Wounds is usually classified primarily based on their place, aetiology, nature from the injury, depth, and their appearance [1]. Generally, wounds can be classified as complete thickness, partial thickness, and superficial [1,2].654653-95-9 Chemical name The cost of management of wounds is high plus the rising population size and urban life style is usually a pointer towards the pressing ought to develop wound dressings that happen to be successful, acceptable, and reasonably priced.1416990-09-4 uses In England, a price of 184 million pounds was spent on dressing items in 2012 [3]. In the Usa of America (USA), an annual price of 20 billion dollars is spent on the management of chronic wounds [4,5].PMID:24238415 The barriers to efficient remedy of wounds could be classified as educational, organizational, clinical, and psychosocial [6] (Table 1). Wound dressings are prepared from biopolymers, synthetic polymers and biomaterials. Biopolymers like chitosan, alginate, fucoidan, hyaluronic acid, and so forth. are nontoxic, readily out there, biodegradable, biocompatible, and nonimmunogenic [7,8]. Alginate application in wound dressings is as a consequence of its special properties, including nontoxicity, biocompatibility, nonimmunogenicity, affordability, and higher absorption capacity [9]. Even so, biopolymers are typically restricted by their poor mechanical properties. They’re combined with synthetic polymers so as to enhance their mechanical properties and tailored to modify their degradation pattern [7,8]. Wound dressings come in distinctive types plus the common complications linked with some of the presently employed wound dressings include their inability to preserve a moist environment; poor absorption of wound exudates; delayed wound healing procedure (i.e., connective tissue synthesis, epidermal migration, and angiogenesis); poor gas exchange between wound as well as the atmosphere; lack of protection against bacterial infection; difficulty in removal on the wound dressing soon after healing; and,Pharmaceutics 2018, 10, 42; doi:10.3390/pharmaceuticswww.mdpi.com/journal/pharmaceuticsPharmaceutics 2018, ten,2 ofnonsterile and allergic reactions [10]. The exceptional properties of alginate make it a prospective biopolymer which will overcome the problems in at present made use of wound dressing by enhancing absorption of wound exudates and minimizing bacterial infections, decreasing adverse allergic effects, and enhancing wound healing for the reason that of its biocompatibility, etc. Additionally, it exhibits hemostatic properties, which are helpful for bleeding wounds [11]. Inside the design and style of wound dressings, the essential elements that should be taken into consideration are their ability to cut down infections, quit bleeding, absorb exudates, improve healing and wound debridement, uncomplicated to make use of, biodegradability, effortlessly sterilised, nontoxicity, superior water vapour, and gas permeability [12]. Wound dressings may be classified as artificial, traditional, and biomaterialbased dressings [12]. This manuscript will offer a comprehensi.
