Special Issue Information

Dear Colleagues,

Although orodispersible tablets (ODTs) were introduced to the pharmaceutical market more than 25 years ago, this dosage form still remains a subject of interest for many pharmaceutical technologists as well as innovators from pharma companies. ODTs gain more and more popularity in the pharmacotherapy of many diseases, including both acute and chronic kinds.

The first methods in the production of ODTs involved freeze drying processes, yet nowadays they are mainly produced via direct compression or tableting after granulation. There are two major reasons the application of these methods has been widely used: the development of superdisintegrants, and the introduction of the co-processed excipients with superior compression properties. Both significantly shortened the disintegration process of compressed ODTs, while the latter also improved mechanical properties and facilitated their production.

Recent trends in the development of ODTs include the formulation of the third generation of these tablets, featuring modified release dosage forms, particularly tablets containing microcapsules, coated micropellets or sustained release granules. Their utilization allows for easy administration to pediatric patients or any other persons having difficulties in swallowing solid dosage forms. Other interesting approaches in the formulation of ODTs is the preparation of orodispersible minitablets (ODMTs, MODTs), as well as research into alternative production technologies for these tablets, such as 3D-printing methods.

This Special Issue of Pharmaceuticals invites both reviews and original articles exploring all aspects of orodispersible tablets. Topics of interest include studies on different features of ODTs, beginning from the conceptualization of the innovative forms through to the formulation process and ending on the pharmacokinetics of these forms and clinical trials of new formulations.

Rhinacanthins, derived from Rhinacanthus nasutus, widely used in traditional medicine, exhibit antifungal, anticancer, antiviral, antibacterial, and antiplatelet aggregation effects. Recently, their anti-diabetic activity was confirmed, which makes them an interesting natural alternative in the therapy of the early stage of diabetes mellitus. The aim of this study was to demonstrate the possibility of formulating orodispersible tablets (ODTs) and orodispersible films (ODFs) containing rhinacanthin-rich extract (RRE). Tablets with 50 mg or 100 mg of RRE were produced by direct compression. ODFs were manufactured by casting of Lycoat RS 720 or polyvinyl alcohol solution with RRE and additional excipients. The mechanical properties and disintegration times of the prepared formulations were studied. The effectiveness of taste masking was analyzed with an electronic tongue system. Six months simplified stability studies were performed in conditions complying to ICH guidelines. Appropriate friability of ODTs was achieved, despite low tensile strength (0.45–0.62 MPa). All prepared ODFs successfully met the acceptance criteria regarding Young’s modulus, tensile strength, and elongation at break. The observed variations in their mechanical properties were dependent on the type and quantity of polymers and plasticizers used. Disintegration time of ODTs ranged from 38.7 s to 54.2 s, while for ODFs from 24.2 to 40 s in the pharmacopoeial apparatus. Analyses made with the electronic tongue showed the significant taste-masking effect in both formulations. The addition of sucralose as a sweetener and menthol with mint flavor as a taste-masking agent was sufficient to mask an RRE’s taste in the case of ODTs and ODFs. Stability studies of ODTs packed in the PVC/Alu blisters showed a decrease in the RRE content below 90% after 6 months. However, ODFs with PVA were physicochemically stable for 6 months while being stored in Alu/Alu sachets. Our study proved for the first time the possibility of the formulation of orodispersible dosage forms with RRE, characterized by good mechanical properties, disintegration time, and appropriate taste masking.
