The buccal mucosa is an attractive site for drug administration as it allows avoiding the enzymatic degradation of the drug in the gastrointestinal tract and its hepatic metabolism. For buccal administration, different drug delivery systems with controlled mucoadhesion have been developed and some of them are available on the market. Mucoadhesion makes it possible to obtain prolonged, local or systemic drug action, and this process is highly influenced by several factors, among which, the reactivity of macromolecules from the formulations is very important. Polysaccharides are increasingly studied due to their abundance in natural resources, low-cost availability and easy chemical modification, but also due to their biocompatibility, biodegradability and non-toxicity properties. This review briefly describes the advantages of using the buccal route of drug administration, the influencing factors that are taken into account for obtaining mucoadhesive dosage forms, and the main polysaccharides and their derivatives used for fabrication of buccal drug delivery systems.

Liposomes are being used as unique drug delivery systems due to their ability to encapsulate both hydrophilic and hydrophobic drugs, as well as for the fact that they improve the disadvantages of free drug administration. However, liposomes have a significant disadvantage - low encapsulation efficiency. In the research carried out, 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC) and cholesterol (Chol), in the ratio (n/n) of 2:1, 3:1 and 4:1 respectively, were used to prepare the liposomes. Blank liposomes (LIP) and vancomycin hydrochloride (VANKA) containing liposomes (VANKA-LIP) were prepared for each of the DSPC and Chol compositions. The aim of our study was to evaluate the effect of liposome composition on the VANKA encapsulation efficiency and release kinetics.

Oral route of drug administration is considered as the safest and easiest route of drug administration. Control release drug delivery system is the emerging trend in the pharmaceuticals and the oral route is most suitable for such kind of drug delivery system. Oral route is more convenient for It all age group including both pediatric and geriatrics. There are various systems which are adopted to deliver drug in a controlled manner to different target sites through oral route. It includes diffusion controlled drug delivery systems; dissolution controlled drug delivery systems, osmotically controlled drug delivery systems, ion-exchange controlled drug delivery systems, hydrodynamically balanced systems, multi-Particulate drug delivery systems and microencapsulated drug delivery system. The systems are formulated using different natural, semi-synthetic and synthetic polymers. The purpose of the review is to provide information about the orally controlled drug delivery system, polymers which are used to formulate these systems and characterizations of one of the most convenient dosage form which is the tablets.

: Administration of substances through the skin represents a promising alternative, in relation to others drug administration routes, due to its large body surface area, in order to offer ideal and multiple sites for drug administration. In addition, the administration of drugs through the skin avoids first-pass metabolism, allowing an increase in the bioavailability of drugs, as well as reducing their side effects. However, the stratum corneum (SC) comprises the main barrier of protection against external agents, mainly due to its structure, composition and physicochemical properties, becoming the main limitation for the administration of substances through the skin. In view of the above, pharmaceutical technology has allowed the development of multiple drug delivery systems (DDS), which include liquid crystals (LC), cubosomes, liposomes, polymeric nanoparticles (PNP), nanoemulsions (NE), as well as cyclodextrins (CD) and dendrimers (DND). It appears that the DDS circumvents the problems of drug absorption through the SC layer of the skin, ensuring the release of the drug, as well as optimizing the therapeutic effect local. This review aims to highlight the DDS that include LC, cubosomes, lipid systems, PNP, as well as CD and DND, to optimize topical skin therapies.


Intra⁃articular injection is one of the most important treatment for osteoarthritis (OA) drug administration. It would improve the pharmacotherapy efficacy and reduce the adverse drug reaction and toxic effect of drugs. In the last decades, the microspheres, nanoparticles, hydrogels, and other drug delivery systems have been extensively studied in OA therapy. This paper reviews the late research development on OA treated via IA drug delivery systems.

The use of various bioerodable polymers as drug delivery systems has gained considerable interest in recent years. Among some of the shapes used as delivery systems are films, rods and microcapsules. The work presented here will deal with the techniques we have utilized for the analysis of the tissue reaction to and actual biodegradation of injectable microcapsules. This work has utilized light microscopic (LM), transmission (TEM) and scanning (SEM) electron microscopic techniques. The design of our studies has utilized methodology that would; 1. best characterize the actual degradation process without artifacts introduced by fixation procedures and 2. allow for reproducible results.In our studies, the gastrocnemius muscle of the rat was chosen as the injection site. Prior to the injection of microcapsules the skin above the sites was shaved and tattooed for later recognition and recovery. 1.0 cc syringes were loaded with the desired quantity of microcapsules and the vehicle (0.5% hydroxypropylmethycellulose) drawn up. The syringes were agitated to suspend the microcapsules in the injection vehicle.
