Accordingly, drugs that are administered orally are a major aspect of patient compliance compared with other routes of administration because of their non-invasiveness and convenience of self- medication. Thus, the taste of drug substances taken orally is a key factor when evaluating the organoleptic quality of drug dosage forms. Thus, numerous studies have been conducted in an attempt to mask the unpleasant taste of pharmaceutical ingredients (Douroumis, 2011, Sohi et al., 2004). Various taste masking technologies have been developed including addition of flavorings or sweeteners (Depalmo, 1999, Wehling et al., 1993), formation of inclusion complexes with β-CD (Motola et al., 1991), bonding with ion exchange resins (Agarwal et al., 2000, Lee et al., 2012), coating or microencapsulating with water-insoluble polymers (Al-Omran et al., 2002, Gao et al., 2006, Jańczyk et al., 2010, Wehling et al., 1993, Yajima et al., 1996, Zgoulli et al., 1999), and modifying the chemical properties of drug substances (Asaka et al., 1992, Hussain et al., 1988). With the exception of addition of flavorings and sweeteners, taste masking is achieved primarily by minimizing direct contact between taste buds on the tongue and drug substances dissolved in the buccal cavity (Sohi et al., 2004). Microencapsulation is defined as the process of manufacturing small particles with sizes in the micrometer range, in which materials are coated with a solid matter or dispersed into a matrix.

Importantly, taste-masking efficiency can be estimated by comparing taste-masked formulations and the unmasked pure drug. The e-tongue system has the advantages of high sensitivity, readiness, and reproducibility, and avoids potential ethical issues involved with human sensory tests of certain substances (Guhmann et al., 2012, Jańczyk et al., 2010, Maniruzzaman et al., 2012, Maniruzzaman et al., 2013, Woertz et al., 2011). The objectives of this study were to design and optimize a taste masked microparticulate system by using a simple spray drying technique for the improvement of patient compliance of SC and to evaluate morphological, crystalline, and molecular properties of taste masked microcapsules. In addition, it was studied to obtain a scientific determination of the masking efficiency of taste-masked SC microcapsules using e-tongue measurements and statistical analysis. Sildenafil citrate (SC) was supplied from Hanmi Pharm Co.

Ltd. (Seoul, Korea). Eudragit® E100 (E100) was obtained from Evonic-Degussa GmbH (Essen, Germany). Methanol and acetonitrile (Honeywell Burdick & Jackson®, Muskegon, MI, USA) were of high performance liquid chromatography (HPLC) grade. Water was purified by reverse osmosis and filtered in house. Microencapsulation is distinguished from conventional granule coating methods by modification of the primary particle (Kirk-Othmer, 2005). For this reason, microencapsulation is used for producing orodispersible systems and oral suspensions, which are highly preferred by pediatric and geriatric patients (Breitkreutz and Boos, 2007) and are necessary for individuals who have swallowing problems (Carnaby-Mann and Crary, 2005).

Thus, such formulations require more attention to adequate masking of bitterness of active pharmaceutical ingredients (Ueda et al., 1993, Zgoulli et al., 1999). Use of pH-dependent gastro-soluble polymers as carriers can be employed for taste masking through microencapsulation, because liberation of the drug in the oral cavity is retarded by a polymer that is not degraded by saliva. Conversely, microcapsule particles dissolve completely in gastric juice, and thus there is no alteration of drug absorption in the GI tract (Al-Omran et al., 2002, Bora et al., 2008, Gao et al., 2006). In this study, we prepared solid dispersion particles consisting of SC and Eudragit® E100, a methacrylate polymer that dissolves below pH 5.0, by a spray drying method.

All other chemicals were of reagent grade. Microencapsulation of SC with E100 was performed using a B-290 mini spray dryer (Büchi, Flawil, SE microcapsules prepared by spray drying were fine powders with a white color. The production yields, LOD values, and drug loading encapsulation efficiency of each microcapsule product are listed in Table 1. The total recovery of products after spray drying was approximately 70%, with the loss of product attributed primarily to the difficulty of manual collection and inter-particular static electricity, which could be improved by pfizer sildenafil 100 scaling up. The taste masking microcapsules containing SC dispersed into the polymer matrix homogenously with the excellent microencapsulation efficiency were prepared by the spray drying.

It was observed that the addition of the E100 increases the taste masking efficiency, and the original bitter taste of the drug may not be sensed by a human when the polymer ratios are more than twice as much as SC. There might be no necessity of the excessive addition of excipients in succeeding solid dosage form This study was supported by a grant of the Korean Health Technology R&D Project, Ministry for Health, Welfare & Family Affairs (A092018) and the National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIP) (No. et al.Detection of counterfeit Viagra® with Raman spectroscopyJournal of Pharmaceutical and Biomedical Analysis(2008) et al.Preparation of roxithromycin-polymeric microspheres by the emulsion solvent diffusion method for taste maskingInternational Journal of Pharmaceutics(2006) Safety and efficacy of sildenafil citrate in the treatment of male erectile dysfunctionClinical Therapeutics(1998) et al.Development of oral taste masked diclofenac formulations using a taste sensing systemInternational Journal of Pharmaceutics(2012) et al.Electronic tongue for the detection of taste-masking microencapsulation of active pharmaceutical substancesBioelectrochemistry(2010) et al.Taste masking of paracetamol by hot-melt extrusion: an in vitro and in vivo evaluationEuropean Journal of Pharmaceutics and Biopharmaceutics(2012) et al.Sildenafil citrate, a selective phosphodiesterase type 5 inhibitor:: research and clinical implications in erectile dysfunctionTrends in Endocrinology & Metabolism(1999) et al.Sustained release solid lipid matrices processed by hot-melt extrusion (HME)Colloids and Surfaces B: Biointerfaces(2013) et al.Taste sensing systems (electronic tongues) for pharmaceutical applicationsInternational Journal of Pharmaceutics(2011) et al.Studies of ion-exchange resin complex of chloroquine phosphateDrug Development and Industrial Pharmacy(2000) Price: Rs 99 / BoxGet Latest Price Cenforce Soft 100 mg is used for erectile dysfunction treatment and Pulmonary Hypertension containing an active ingredient Sildenafil Citrate, 100 mg per tablet.

In order to obtain quantitative data about taste, levels of bitterness between raw materials and modified particulate systems can be measured using an electronic tongue (e-tongue). E-tongue devices have been used previously to evaluate the taste of food products and oral pharmaceutical formulations, as well as to monitor environmental samples. The e-tongue system is based on potentiometric measurements. Sensors interact with active ingredients that have a specific taste in aqueous media, then the chemical interaction is transformed to an electrical signal by measuring the voltage difference between a reference electrode and probe. Data obtained from e-tongue measurements are recorded and analyzed by univariate or multivariate methods as dictated by the experiment. The methods of multivariate statistical analysis include principal component analysis (PCA) and partial least square regression (PLS). Importantly, taste-masking efficiency can be estimated by comparing taste-masked formulations and the unmasked pure drug.
