Abstract In recent years, there has been a tendency toward creating innovative, easy to use and patient-friendly drug delivery systems suitable for every consumer profile, which would ensure safety, stability and acceptability of a drug. One of the relatively novel and promising approaches is the manufacture of orodispersible films (ODFs), which is an upcoming area of interest in drug delivery. They are defined as polymer thin films that disintegrate in the oral cavity within seconds, without drinking water or chewing, and eliminate the risk of choking. Gaining special usefulness in therapies of children and the elderly, ODFs seem to fill the gap in the range of preparations available for these groups of patients. As no detailed monography of ODFs including testing methods and uniform requirements has been presented in any of the pharmacopoeias to date, the aim of this article is to give an overview of the applied testing methods, their modifications and innovative approaches related to ODF quality assessment.

Vesicular drug delivery system has various advantages thereby improving therapeutic efficacy and by sustaining and controlling action of drugs. Liposomes, sphingosomes, ethosomes, cubosomes, pharmacasomes, niosomes, transferosomes are the newly developed vesicular drug delivery system. This review article mainly deals with the sphingosomal drug delivery system. Sphingosomes are vesicular drug delivery systems in which an aqueous volume is enclosed with sphingolipid bilayer membranes. Sphingosomes has an enhanced area of interest because of their applicability in improving the in vivo delivery of various chemotherapeutic agents, biological macromolecules and diagnostics. Sphingosome has major advantages over other vesicular drug delivery systems like high stability, more in vivo circulation time, high tumor loading efficacy in case of cancer therapy as compared to liposomes, niosomes etc. Sphingosomes are clinically used vesicular delivery system for chemotherapeutic agent, biological macromolecule and diagnostics. This review concluded that sphingosome represents a promising vesicular drug delivery system for a range of possible therapeutic applications.

Abstract Oral health reflects the general health and it is fundamental to well-being and quality of life. An infection in the oral cavity can be associated with serious complications in human health. Local therapy of these infections offers many advantages over systemic drug administration, targeting directly to the diseased area while minimizing systemic side effects. Specialized drug delivery systems into the oral cavity have to be designed in such a fashion that they resist to the aqueous environment that is constantly bathed in saliva and subject to mechanical forces. Additionally, a prolonged release of drug should also be provided, which would enhance the efficacy and also decrease the repeated dosing. This review is aimed to summarize the current most relevant findings related to local drug delivery of various drug groups for prevention and treatment of infections (viral, bacterial, fungal) and infection related manifestations in the oral cavity. Current therapeutic challenges in regard to effective local drug delivery systems will be discussed and the recent approaches to overcome these obstacles will be reviewed. Finally, future prospects will be overviewed to promote novel strategies that can be implemented in clinical management for prevention and treatment of oral infections.

As per the present global scenario, Parkinson’s disease (PD) is considered to be the second most common neurodegenerative disorder which is a keen area of interest among researchers. The conventional therapies generally employed against PD are associated with serious drawbacks including limited transport across selectively permeable BBB, hepatic metabolism, intestinal barrier, etc. This urges the need to develop novel therapeutic alternatives. The oral route being the most preferred route of administration needs to be explored for new and more intelligent drug delivery systems. Nanotechnology has been proposed to play a promising role in reversing the progression of the disease via the oral route. Nanocarriers, namely nanoparticles, lipid nanoparticles, nanoemulsions, nanocrystals, nanomicellar formulations, self-nanoemulsifying drug delivery systems and alginate nanocomposites have been investigated upon to modulate the fate of drugs inside the human body when administered orally. The development of various nanotherapeutics for the treatment of PD has been reviewed, depicting an enhanced bioavailability to provide a desired therapeutic outcome. The new advances in the therapy have been explored and highlighted through the body of this review. However, a therapeutically effective concentration at the target site remains a challenge, therefore extensive exploration in the field of nanotherapeutics may facilitate superior drug delivery to CNS via oral route thereby improving the state of disease progression.

Orodispersible dosage forms are attractive and innovative drug delivery systems that can fulfill individual patient needs, especially in children, elderly and among dysphagic patients. Indeed, they rapidly disperse in the mouth upon contact with the saliva without the need for water or munching. Examples of such dosage forms include orodispersible tablets (ODT), and orodispersible films (ODF). The ability to obtain ODF with different dimensions (sizes and thicknesses) makes them a suitable for personalized dosing of single or a fixed-dose combination of drugs in special patient populations. Several biopolymers are currently being exploited in the development of orodispersible dosage forms including alginates due to their versatility, availability, naturally occurring, and biosafety profile. This chapter provides an appraisal on the various applications of alginates in the preparations and their role on the properties of orodispersible dosage forms and highlights future perspectives of this very versatile biopolymer for these innovative drug delivery systems.

Mucosal Drug Delivery

Oral mucosal drug delivery system is widely applicable as novel site for administration of drug and controlled release action by preventing first pass metabolism and enzymatic degradation due to GI microbial flora. The oral cavity represents a challenging area to develop an effective drug delivery modelling. This arises due to the various inherent functions of the oral cavity (eating, swallowing, speaking, chewing), as well as the presence of the fluid that is involved in all these activities, saliva. This fluid is continually secreted into and then removed from the mouth. Oral Mucosa drug delivery system provides local and systemic action. The delivery of drugs through the buccal mucosa has attracted much research interest over the past two decades and numerous approaches, both conventional and complex, have been developed in an attempt to deliver a variety of pharmaceutical compounds via the buccal route. To outline the progress in the in vitro and in vivo modeling of Mucosal drug delivery and provide a critical review of currently used methods. The purpose of this review is to represent the modeling of oral cavity with Mucoadhesive drug delivery systems and clarify the potential alternative to conventional therapy.
