A mucoadhesive, thermoreversible in situ nasal gel of geniposide for neurodegenerative diseases
Neurodegenerative diseases are becoming prevalent as the population ages. Geniposide could inhibit oxidative stress, reduce apoptosis, protect neuron, and has been used for therapy of the neurodegenerative diseases. The bioavailability of geniposide by nasal route is greater than that by oral administration. However, mucociliary clearance is a rate-limiting factor for nasal route administration...
متن کاملRheological evaluation of thermoreversible and mucoadhesive nasal gels of Zolmitriptan.
BACKGROUND AND OBJECTIVES Rheological evaluation of thermoreversible mucoadhesive nasal gel of zolmitriptan is done to determine the steady shear behaviour and gelation temperature. The thermoreversible mucoadhesive polymers are sucessesfully used to increase the contact time of the therapeutic compound in the nasal cavity as well as they cause enhancement in permeation of drug through the nasa...
متن کاملNovel Mucoadhesive Polymers for Nasal Drug Delivery
The use of nasal cavity as a route of administration of drugs, specifically systemically acting drugs that pose a delivery challenge, have become an area of great interest to the pharmaceutical companies in the past decade. The physiology of the nasal cavity allows for variety of drug delivery possibilities and destinations which include local, systemic, vaccine, and access to the central nervo...
متن کاملDevelopment of Abelmoschus esculentus (Okra)-Based Mucoadhesive Gel for Nasal Delivery of Rizatriptan Benzoate
Purpose: To develop a safe mucoadhesive gel for nasal drug delivery using okra polysaccharide. Methods: Rizatriptan benzoate nasal gel was developed using natural polysaccharide obtained from the Abelmoschus esculentus. The gel formulation was characterized for pH, viscosity, mucoadhesion, and in vitro permeation. Permeation parameters obtained include drug flux (j), permeation coefficient (kP)...
متن کاملOptimization of Thermoreversible In Situ Nasal Gel of Timolol Maleate
Nasal route had shown better systemic bioavailability due to its large surface area, porous endothelial membrane, high total blood flow, and avoidance of first-pass metabolism. Timolol maleate is a beta blocker used primarily in the treatment of hypertension. Drug undergoes extensive hepatic first-pass metabolism (80%). The drug has half-life of 4 hrs. Oral bioavailability of timolol maleate is...
