Description	Polyvinyl Alcohol (PVA) is a versatile synthetic polymer used in the pharmaceutical industry primarily as an excipient. It serves multiple roles due to its biocompatibility, film-forming abilities, and chemical stability. In solid dosage forms, PVA is commonly employed as a film-coating agent to enhance the stability, taste, and appearance of tablets and capsules. This helps in modulating drug release profiles and improving patient compliance. Additionally, PVA acts as a binder in tablet formulations, providing mechanical strength to the compacted tablet. Its excellent adhesive properties are also utilized in transdermal patches and ocular drug delivery systems, where it creates a protective and hydrophilic barrier. Furthermore, PVA is used as a suspending and emulsifying agent in liquid formulations, enhancing the solubility and stability of active pharmaceutical ingredients. Overall, its multifunctional properties make polyvinyl alcohol a valuable excipient in the development and manufacturing of various pharmaceutical products.
