Abstract:
Film-forming sprays provide a number of advantages over conventional topical treatments, including equal medication distribution and dosing, increased bioavailability (increase local drug concentration), and less irritability (Dosing frequency). Polymers and excipients that improve the characteristics of preparations and increase the stability of active substances are the building blocks of mucoadhesive film-forming sprays. Films made from diverse combinations of polymer and excipient exhibited a wide range of characteristics. This reveiw examines the many types of polymers and excipients, the

A polymer is a very-long-chain macromolecule in which hundreds or thousands of atoms are linked together to form a one-dimensional array. The skeletal atoms usually bear side groups, often two in number, which can be as small as hydrogen, chlorine, or fluorine atoms or as large as aryl or long-chain alkyl units. Polymers are different from other molecules because the long-chain character allows the chains to become entangled in solution or in the solid state or, for specific macromolecular structures, to become lined up in regular arrays in the solid state.

This is achieved by the formation of a highly cross-linked polymeric matrix around a template, which can be the target molecule itself or a close structural analogue.

For some of those biopolymers, the narrow window in which they can be processed has delayed their potential use for packaging applications. In rigid packaging, two-step processes are
