This study describes the in vitro/ex vivo buccal release of chlorhexidine (CHX) from nine mucoadhesive aqueous gels, as well as their physicochemical and mucoadhesive properties: CHX was present at a constant 1% w/v concentration in the chemical form of digluconate salt. The mucoadhesive/gel forming materials were carboxymethyl- (CMC), hydroxypropylmethyl- (HPMC) and hydroxypropyl- (HPC) cellul...

BACKGROUND Acyclovir has pharmacokinetic limitations, including poor oral bioavailability of 15%-30%, high variability, and short elimination half-life of 2.3 hours. These limitations necessitate frequent administration of acyclovir, up to five times daily, leading to poor patient compliance, which in turn leads to a reduction in therapeutic efficacy and development of resistance. METHODS A g...

Objective: Buccal drug delivery is the most suited route for local as well systemic of drugs. Cilnidipine an L/N type dihydropyridine 4th generation calcium channel blocker (CCB), which decreases hypertension by blocking N-type to attenuate vascular sympathetic neurotransmission. It has high first-pass metabolism leading low bioavailability. Hence present research work was undertaken formulate ...

BACKGROUND Targeted drug delivery to colon would ensure direct treatment at the disease site, decrease in dose administration and reduction side effects improved drug utilization. OBJECTIVE The purpose of this research was to decrease gastric side effects of piroxicam by formulating microspheres of alginate and algino-pectinate beads of the drug. MATERIALS AND METHODS Ionotropic gelation wa...

The objective was to describe and recommend the most effective combination of Natural-Based Product (NBP) mucoadhesive for Recurrent Aphthous Stomatitis (RAS) treatment. This systematic review writing based on PRISMA guidelines. articles published in last 10 y were selected using PubMed Google Scholar database carried out during May 2021. keywords were: natural-based product, mucoadhesive, Stom...

conclusions algino-pectinate mucoadhesive formulations exhibited promising properties of a sustained release form for piroxicam and provided distinct tissue protection in stomach. objective the purpose of this research was to decrease gastric side effects of piroxicam by formulating microspheres of alginate and algino-pectinate beads of the drug. materials and methods ionotropic gelation was us...

In this paper, different formulation types of microparticulate systems such as beads, microbeads, microspheres and microsponges using to special attention chitosan, alginate and eudragit RS 100 are reviewed. Chitosan and alginates are natural, anionic or cationic, biocompatible, biodegredable and non-toxic polymers. They have excellent potential for pharmaceutical and biopharmaceutical applicat...

In recent years, orally disintegrating films (ODFs) have been studied as alternative ways for drug administration. They can easily be applied into the mouth and quickly disintegrate, releasing with no need of water ingestion enabling absorption through oral mucosa. The ODFs matrices are typically composed hydrophilic polymers, in which natural polymers highlighted since they extracted from sour...
