The mucoadhesive disks of various polymers were fabricated with objective of comparing the mucoadhesive strength and mucoretentability with the isolated DPP. The mucoadhesive polymers used in formulations were sodium carboxy methyl cellulose, carbopol (cp934), hydroxyl propyl methyl cellulose (HPMC K4M), and date palm fruit pulp polysaccharide (DPP). These formulations were characterized for ph...

BACKGROUND AND THE PURPOSE OF THE STUDY The poor bioavailability and therapeutic response exhibited by the conventional ophthalmic solutions due to precorneal elimination of the drug may be overcome by the use of mucoadhesive in situ gel forming systems that are instilled as drops into the eye and undergo a sol-gel transition in the cul-de-sac and have good mucoadhesion with ocular mucus layers...

Aim: The objective of the present study is to design and evaluate mucoadhesive microspheres for oral controlled release. Materials and Method: Rosiglitazone maleate microspheres with a coat consisting of alginate and a mucoadhesive polymer sodium carboxymethylcellulose, carbopol 934P and hydroxypropylmethylcellulose were prepared by an orifice-ionic gelation process. The microspheres were evalu...

Nifedipine is an antihypertensive BCS class II drug which has poor bioavailability when given orally. The objective of the present study was to increase the bioavailability of nifedipine, by formulation and evaluation of a buccoadhesive liquisolid system using magnesium aluminium silicate (Neusilin) as both carrier and coating material and dissolution media were selected based on the solubility...

Objective: The objective of this research was to formulate and evaluate pectin and HPMC different grades mucoadhesive microspheres in combination with sodium alginate for controlled release of maraviroc. Methods: The maraviroc mucoadhesive microspheres was successfully developed by Ionotropic gelation technique, using sodium alginate, pectin, HPMC K4, K15, and K100 as mucoadhesive polymer in va...

The purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. Propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934P as mucoadhesive polymer and ethyl cellulose as carrier ...

In an effort to augment the anti-Helicobacter pylori effect of amoxicillin, mucoadhesive microspheres, which have the ability to reside in the gastrointestinal tract for an extended period, were prepared. The microspheres contained the antimicrobial agent and an adhesive polymer (carboxyvinyl polymer) powder dispersed in waxy hydrogenated castor oil. The percentage of amoxicillin remaining in t...

Mucoadhesive polymers are an essential tool in the treatment of diseases where dry mucosal surfaces are involved. In this review, we focus on the application of mucoadhesive polymers in the context of dry eye, dry mouth, and dry vagina syndrome, collectively named 'dry X syndrome'. With a prolonged residence time on mucosal membranes, mucoadhesive materials are as targeted treatment option, wit...

The aim of the present study was to prepare and evaluate an osmotically controlled mucoadhesive cup-core (OCMC) containing aceclofenac. A special technique was used while preparing an OCMC. Stability of OCMC was determined in natural human saliva, and it was found that both pH and device are stable in human saliva. OCMC was evaluated by weight uniformity, thickness, hardness, friability, swelli...

Mucoadhesive drug delivery systems interact with the mucus layer covering the mucosal epithelial surface, and mucin molecules and increase the residence time of the dosage form at the site of absorption. The drugs which have local action or those which have maximum absorption in gastrointestinal tract (GIT) require increased duration of stay in GIT. Thus, mucoadhesive dosage forms are advantage...
