ABSTRACT
The active ingredients are rarely administered directly but in the form of preparations or formulated drugs. The pharmaceutical forms contain, in addition to the active pharmaceutical ingredient, a number of components in order to facilitate the manufacturing process and drug delivery. The study of marine biodiversity, particularly polysaccharides, represents a major challenge for research. It is called “blue chemistry”, by analogy with “green chemistry”. Seaweeds are rich sources of sulfated polysaccharides, including some ones that have become valuable additives in the food industry because of their rheological properties as gelling and thickening agents. Agar is a phycocolloid, which is constructed from complex saccharide molecules. The green alga is the most diverse group of algae and, it is a paraphyletic group. Bacterial polysaccharides has potential applications in the pharmaceutical industry. The conventional oral and intravenous routes of drug administration do not provide ideal pharmacokinetic profiles especially for drugs, which display high toxicity and/or narrow therapeutic windows.
