Introduction. Dental gel is one of the modern dosage forms with optimal biopharmaceutical properties for the treatment and prevention of oral diseases An isoquinoline alkaloid berberine is the promising active substance with antibacterial and anti-inflammatory effect, capable of forming stable dispersed systems with gel-forming components. It is noteworthy that, despite the pronounced antimicrobial activity of the alkaloid berberine, there is currently no dental dosage form with this component on the pharmaceutical market, and therefore research in this direction is of great interest.Aim. Selection of the optimal technology for obtaining dental gel with berberine for the treatment of oral diseases.Materials and methods. Berberine bisulfate (manufactured by CJSC «Vifitech», Obolensk, Moscow region, RF), poloxamers P407 and P338 (EP, USP/N; BASF, Germany), propylene glycol (USP; BASF, Germany), sodium chloride (Sigma-Aldrich, Germany, Cat. No. S9888), mucin type II from a pig stomach (Sigma-Aldrich, Germany, Cat. No. M2378). In the development of the composition and technology for the preparation of gels, a magnetic stirrer with a temperature control function (C-MAG HS 7 from IKA, Germany) was used. Gels were prepared by the «hot method» and «cold method».Results and discussion. The production of the gel by the «hot method» provided a uniform dosage form. The obtained pH value is within the range of optimal diapason. Measurement of the specific peel force of the model gel sample showed pronounced mucoadhesive properties, which indicates that there is no need to adjust this parameter by introducing additional components into the formulation. The spectroscopic method is applicable for the analysis of berberine gel. It has been found that a significant dilution of the reference substance sample is required to develop an identification procedure.Conclusion. The production of a sample of the dosage form by the «hot method» is optimal, which is probably due to the effect of solubilization and better distribution of the active substance in the base.

One of the promising areas of the pharmaceutical industry is the development of local drug delivery systems consisting of a biocompatible matrix and a drug. Such local delivery systems include medicinal films. Ensuring pharmacological action, accuracy of dosing, strong fixation to damaged tissues of the mucous membrane, prolongation of action are the undoubted advantages of medicinal films in comparison with traditional means of treating wound processes. The development of the technology of the drug film containing in its composition the drug cycvalone, which has a wide range of biological activity-antioxidant, anti-inflammatory, antibacterial and others - is an urgent task of pharmacy. As a result of the conducted research, the technology of a drug film with cycvalone in the form of an inclusion complex with β-cyclodextrin based on a matrix of a biodegradable polymer of sodium alginate was developed. It should be noted the availability, safety and pharmacological effectiveness of medicinal substances used in the technology of the dosage form. The inclusion of cyclodextrin in the composition of the film is due to the solubilization of the active substance molecule and an increase in the bioavailability of cycvalone during application therapy. Introduction of cycvalone in the form of complex inclusion also has a positive effect on the uniformity of distribution of the drug in the matrix and, consequently, determines the accuracy of drug dosing. After the release of the active substance, cyclodextrin is able to show detoxifying properties in the wound. The use of a modern biodegradable material as a film-forming agent provides a prolonged action of active substances, high bioavailability and enhanced therapeutic properties of the composition. The values of quality indicators of medicinal films confirming the rational selection of the composition and the optimal technology of the dosage form were experimentally established.

: The current treatment and prevention of oral disorders follow a very sectoral control and procedures considering mouth and its structures as system completely independent from the rest of the body. The main therapeutic approach is carried out on just to keep the levels of oral bacteria and hygiene in an acceptable range compatible with one-way vision of oral-mouth health completely separated from a systemic microbial homeostasis (eubiosis vs dysbiosis). This can negatively impact on the diagnosis of more complex systemic disease and its progression. Dysbiosis is consequence of oral and gut microbiota unbalance with consequences, as reported in current literature, in cardio vascular disease, diabetes mellitus, rheumatoid arthritis, and Alzheimer’s disease. Likewise, there is the need to highlight and develop a novel philosophical approach in the treatments for oral diseases that will necessarily involve non-conventional approaches.

Polymers in drug formulation technology and the engineering of biomaterials for the treatment of oral diseases constitute a group of excipients that often possess additional properties in addition to their primary function, i.e., biological activity, sensitivity to stimuli, mucoadhesive properties, improved penetration of the active pharmaceutical ingredient (API) across biological barriers, and effects on wound healing or gingival and bone tissue regeneration. Through the use of multifunctional polymers, it has become possible to design carriers and materials tailored to the specific conditions and site of application, to deliver the active substance directly to the affected tissue, including intra-periodontal pocket delivery, and to release the active substance in a timed manner, allowing for the improvement of the form of application and further development of therapeutic strategies. The scope of this review is polymeric drug carriers and materials developed from selected multifunctional groups of natural, semi-synthetic, and synthetic polymers for topical therapeutic applications. Moreover, the characteristics of the topical application and the needs for the properties of carriers for topical administration of an active substance in the treatment of oral diseases are presented to more understand the difficulties associated with the design of optimal active substance carriers and materials for the treatment of lesions located in the oral cavity.

Objective: The aim of the study was to develop an easy, sensible and rapid method for the estimation of amikacin in both pure and marketed formulation using the spectrophotometric method.Methods: Due to lack of chromophoric group in the amikacin, it was derivatized with 0.1 mmol chloranillic acid reagent. For the estimation of amikacin, Shimadzu UV-1700 model spectrophotometer with UV probe software was used. The method was based simple on charge transfer complexation of the drug with a p-chloranilic acid reagent to give a purple coloured product which was measured at 524 nm against blank solution.Results: The derivatised product of amikacin was detected at a wavelength of 524 nm. Linearity was observed with the concentration range of 20-100 µg/ml with a regression coefficient of 0.9803. Results of all the parameters were within the acceptance criteria with % RSD less than 2.Conclusion: The spectroscopic method was validated as per ICH guidelines and was found to be applicable for routine quantitative analysis of amikacin in marketed formulations also. The results of linearity, precision, accuracy LOD and LOQ were within the specified limits. The method is highly sensitive, robust, reproducible and specific.

A simple, accurate and precise UV spectrometric method has been developed for the simultaneous determination of valsartan and hydrochlorothiazide in tablet dosage form. Spectra of valsartan and hydrochlorothiazide in methanol and water (50:50 V/V) show λ max at 250.0 nm and 271.4 nm, respectively. Valsartan and hydrochlorothiazide are subjected to various stress conditions like acid, alkali, thermal and photolytic degradation. Beer’s law was obeyed in concentration range of 4- 24 µg mL-1 for valsartan and 0.5-3 µg mL-1 for hydrochlorothiazide at their respective wavelengths. The proposed method was successfully applied to tablet dosage form for determination of both drugs. The percentage recovery of valsartan and hydrochlorothiazide were found to be 100.19 % and 99.51 %, respectively. A novel accurate and precise stability indicating spectroscopic method has been developed for estimation of valsartan and hydrochlorothiazide.
