Taste masking

The main objective of the current research work was to formulate and evaluate taste masked effervescent tablet. Dicyclomine HCl is very bitter in taste. The purpose of this research was to reduce the bitterness of Dicyclomine HCl using Hydroxyl Propyl Betacyclodextrin by inclusion complex method and formulate effervescent tablet with sufficient mechanical integrity and to achieve faster disintegration in the water.: Components excipients and Dicyclomine HCl HP- Betacyclodextrin inclusion complex were selected based on preliminary studies. A comparative evaluation of the taste masking was carried out for developed formulation. Citric acid, tartaric acid, sodium bicarbonate was used in 1:2:3.44 ratio for effervescent mixture. 32full factorial design was applied. Ratio of citric acid and hardness were taken as independent variables dissolution of Paracetamol and Dicyclomine HCl at 5 minutes, disintegration time, and friability were taken as dependent variables. Optimized formulation was then evaluated for general tablet evaluation and dissolution. Short term accelerated stability studies were performed for tablets prepared using optimized formulation. Optimized batch composition had ratio of Paracetamol: citric acid and hardness at concentration of 1:0.45 (mg) and 8 (kg/cm2) respectively. All the evaluation parameters of the optimized batch met the acceptance criteria. The taste masked effervescent tablet of Paracetamol and Dicyclomine HCl was formulated successfully by wet granulation method.

In the present research work attempt was to formulate tasteless complexes of Ambroxol hydrochloride using cation exchange resins and to evaluate molecular properties of drug complexes. Tulsion 343 that contained crosslinkedpolyacrylic backbone was used. The drug loading onto ion-exchange resin was optimized for mixing time, activation, effect of pH, mode of mixing, ratio of drug to resin, and temperature. Drug resin complexes (DRC) were evaluated for taste masking and characterized by x-ray diffraction study and infrared spectroscopy.Ambroxol hydrochloride is a potent mucolytic agent capable of inducing bronchial secretion. It is used in the treatment of asthma, bronchitis and cough.It is a highly bitter drug and not suitable for pediatric patients hence taste masking of drug was required. Ambroxol hydrochloride-Tulsion 343 complex of ratio 1:0.7% w/w  was  developed into  suspension formulation  using different  suspending agents  with  varying concentration  and was evaluated for  sedimentation volume, pH, drug content  and viscosity. The prepared suspensions were evaluated for taste, drug content, particle size, viscosity, sedimentation volume, drug release. The results showed that Ambroxol Hydrochloride was successfully taste masked,showed easy redispersibility and more than 80% drug release within 45 minutes and when compared with  marketed preparation.

Many oral dosage forms, bulking agents and beverage products have unpleasant taste. The bitter taste is an undesirable trait of the product or formulations and can considerably affects its acceptability by consumer. So, they should be formulated in a palatable form. Bitter taste in such systems can be reduced or eliminated by various methods, but no universally applicable technologies are yet recognized. This article is about the discussion of recent approaches for minimizing the unpleasant taste for oral pharmaceuticals.   Key words: Taste masking, Eudragit.
