Humans have taken advantage of the adaptability of polymers for centuries in the form of resins, gums tars, and oils. However, it was not until the industrial revolution that the modern polymer industry began to develop. Polymers represent an important constituent of pharmaceutical dosage forms. Polymers have played vital roles in the formulation of pharmaceutical products. Polymers have been used as a major tool to manage the drug release rate from the formulations. Synthetic and natural-based polymers have found their way into the biomedical and pharmaceutical industries. Synthetic and Natural polymers can be produced with a broad range of strength, heat resistance, density, stiffness and even price. By constant research into the science and applications of polymers, they are playing an ever-increasing role in society. Diverse applications of polymers in the present pharmaceutical field are for controlled drug release. Based on solubility pharmaceutical polymers can be classified as water-soluble and water-insoluble. In general, the desirable polymer properties in pharmaceutical applications are film forming, adhesion, gelling, thickening, pH-dependent solubility and taste masking. General pharmaceutical applications of polymers in various pharmaceutical formulations are also discussed

Patient compliance of drug therapy is the key factor in achieving the pharmaceutical effect. Taste masking is particularly important in pediatrics and geriatrics because the unpleasant taste negatively affects drug uptake. Patient compliance can be improved through balanced organoleptic properties of medicines. It is particularly important to choose optimal correction method for medicines with high concentration of the active substance. Hopantenic acid has been chosen as a model drug due to its bitter taste. Taste masking technologies for creating a new dosage form with optimal organoleptic properties are proposed in the article. The objective is to achieve an experimentally justified choice of technological approach to masking bitter taste of a substance and to create a new dosage form on its basis. Materials and methods. Alternative technologies were considered to solve this problem: granulation, creation of complexes with ion-exchange resins, introduction of a gel composition and taste-masking using sweeteners. Organoleptic properties in dry compositions (pure substance of hopantenic acid, granulate and resinate based on it), and also after preparation of liquid dosage forms and incorporation them into gel, were evaluated by A. I. Tentsova method. Choice of sweetener and its concentration to achieve an optimally balanced taste took place at the final stage. Hopantenic acid was chosen as a model substance. Hopantenic acid is a nootropic drug stimulating cognitive functions, nervous system, enhancing intellectual functioning, decreasing nervous system activity, with anticonvulsant action. The main therapeutic indications are mental retardation, dementia, epilepsy. Results and discussion. The study has shown that optimal technology for masking unpleasant taste of hopantenic acid is its introduction into a gel composition, and a promising dosage form is an oral gel. Compri-Zucker G sweetener (Südzucker АG, Germany) in concentration of 5 % has been chosen to create pleasant taste due to its highest taste rating. Conclusion. It has been determined as a result of the study that oral gel with active drug concentration of 5 % and sweetener concentration of 5 % has optimal organoleptic properties. Thus, this combination of active and additional substances can be considered the most perspective for developing a new dosage form of a medicine.

The present study deals with the formulation and evaluation of mefloquine hydrochloride nanoparticles. Mefloquine is a blood schizonticidal quinoline compound, which is indicated for the treatment of mild-to-moderate acute malarial infections caused by mefloquine-susceptible multi-resistant strains of P. falciparum and P. vivax. The purpose of the present work is to minimize the dosing frequency, taste masking toxicity and to improve the therapeutic efficacy by formulating mefloquine HCl nanoparticles. Mefloquine nanoparticles were formulated by emulsion diffusion method using polymer poly(ε-caprolactone) with six different formulations. Nanoparticles were characterized by determining its particle size, polydispersity index, drug entrapment efficiency, drug content, particle morphological character and drug release. The particle size ranged between 100 nm to 240 nm. Drug entrapment efficacy was >95%. The in-vitro release of nanoparticles were carried out which exhibited a sustained release of mefloquine HCl from nanoparticles up to 24 hrs. The results showed that nanoparticles can be a promising drug delivery system for sustained release of mefloquine HCl.

The purpose of this study was to evaluate the potential of polymers for masking the taste of bitter drugs when incorporated into orally disintegrating tablets. The tablets were produced by simple wet granulation technique with a model compound (baclofen) which is moderately bitter. The formulating procedure had two variables to obtain good taste masking with desirable characteristics. The optimal granulation process parameters were polymer selection and its concentration (w/w), suitable for pilot scale level. Dextrates, β- cyclodextrin, eudragit EPO and PVP K-30 were used in preparation of granules by using water and iso-propyl alcohol. Crospovidone was used intra and extra granularly as superdisintegrant.  Sodium bicarbonate and citric acid were used as effervescent for fast disintegration of tablets, which also optionally act as desensitizer of taste buds. Results from evaluation of tablets indicated a disintegration time (avg) of 30-35 sec and 100% drug release was achieved within 5 min. But taste masking was achieved by only with eudragit EPO. Results from an evaluation by a panel of six human volunteers demonstrated that the orally disintegrating tablets which are prepared by using polymer Eudragit EPO (5% and 7.5% w/w of tablet) and PVP (7.5% w/w of tablet) improved taste, significantly. On studying physical parameters, F9 formulation demonstrated acceptable level of hardness and friability with good taste masking and it was thus considered as an optimized formulation

Active Substances

A variety of pharmacologically active substances, including chemotherapeutic drugs and the substances from traditional Chinese medicine (TCM), always exhibit potent bioactivities after oral administration. However, their unpleasant taste (such as bitterness) and/or odor always decrease patient compliance and thus compromise their curative efficacies in clinical application. Therefore, the developments of taste-masking techniques are of great significance in improving their organoleptic properties. However, though a variety of taste-masking techniques have been successfully used to mask the unpalatable taste of chemotherapeutic drugs, their suitability for TCM substances is relatively limited. This is mainly due to the fact that the bitter ingredients existing in multicomponent TCM systems (i.e., effective fractions, single Chinese herbs, and compound preparations) are always unclear, and thus, there is lack of tailor-made taste-masking techniques to be utilized to conceal their unpleasant taste. The relevant studies are also relatively limited. As a whole, three types of taste-masking techniques are generally applied to TCM, including (i) functional masking via sweeteners, bitter blockers, and taste modifiers; (ii) physical masking via polymer film-coating or lipid barrier systems; and (iii) biochemical masking via intermolecular interaction, β-cyclodextrin inclusion, or ion-exchange resins. This review fully summarizes the results reported in this field with the purpose of providing an informative reference for relevant readers.
