Guru Angad Dev Veterinary and Animal Sciences University (GADVASU) was established at Ludhiana by an act of the Punjab Legislature No. 16 of 2005 notified in the Punjab Government Gazette on August 9, 2005 and it started functioning w.e.f. April 21, 2006 for promoting livestock production, health and prevention of the disease(s) through integrated teaching, research and extension programme(s).

The PGIMER owes its inception to the vision of late Sardar Partap Singh Kairon, the then Chief Minister of Punjab and the distinguished medical educationists of the then combined state of Punjab, supported by the first Prime Minister of India Pt.

Abstract:
Mucoadhesion is the prevalent interest in the design of drug delivery systems. Mucoadhesion can be defined as the state in which two materials, at least one of which is biological (mucosa) in nature, are held together for a prolonged time period by means of interfacial forces. This mucoadhesive system offers many advantages as it allows for reduction in daily administrations and daily drug dosage and is suitable for the treatment of irritation, pain, and discomfort associated with gingivitis, sore throats, laryngopharyngitis, cold, and periodontal surgery. Moreover, it adheres well to the gum and is very simple to apply, which means that patient compliance is improved. Mucoadhesive drug delivery system are designed to enable prolonged residence time of the dosage form at the site of application or absorption and facilitate an intimate contact of the dosage form with the underline absorption surface. The present review describes mucoadhesion, mucoadhesive polymers and their classification, stages, mechanism and theories of mucoadhesion and factors affecting them along with its evaluation. However, the research on mucoadhesives, is still in its early stage and further advances need to be made for the successful translation of the concept into practical application in controlled drug delivery.
