They are consumed as microbial food supplements.The mechanism of action of probiotics is associated with their ability to enhance immune response, compete with pathogenic microbes for adhesion sites, to antagonize these pathogens and production of antimicrobial substances. Immunomodulatory effect of probiotics can be explained by molecular and proteomic studies. Health benefits of probiotics includes prevention and treatment of various health conditions and diseases such as gastrointestinal disorders, lactose intolerance, irritable bowel syndrome, inflammatory bowel disease, Necrotising colitis, allergies, urogenital infections, various cancers, Arthritis, AIDS, Upper respiratory infections, oral health such as prevention of dental caries, periodontal diseases and haliotis as well as many other effects which are under exploration.

Antiemetic drugs are used in the treatment of nausea and emesis. Development of novel delivery systems for antiemetic drugs, as an alternative to conventional preparations, is essential in terms of good patient compliance and improving bioavailability. The nasal route offers exclusive superiorities, such as rapid and high drug absorption, and high patient compliance. Consequently, a considerable amount of research has been carried out on the development of nasal delivery systems for antiemetic drugs. This review deals with the importance of nasal delivery of antiemetic drugs and the studies performed on this subject. The present review illustrates the studies conducted on the development of nasal delivery systems. Due to its better stability and bioavailability, the nasal route could be considered as an attractive alternative to oral and parenteral...
