Taste-masking assessment of orally disintegrating tablets and lyophilisates with cetirizine dihydrochloride microparticles

Overview 

Orally disintegrating tablets and oral lyophilisates are innovative dosage forms designed to dissolve rapidly in the buccal cavity without the need for water. A primary challenge in developing these formulations is overcoming the unpleasant taste of active pharmaceutical ingredients. This study investigates the formulation and taste-masking efficacy of cetirizine dihydrochloride (CET), an extremely bitter second-generation antihistamine, using polymer-coated microparticles.

Methodology

The researchers employed a multi-step approach to formulate and test the orodispersible dosage forms:

• Microparticle Formulation: CET was microencapsulated with Eudragit E PO (a barrier coating copolymer) using a spray-drying technique to mask its bitter taste.
• Dosage Form Preparation: Orally disintegrating tablets were manufactured via direct compression, while oral lyophilisates were produced using a freeze-drying process.
• Physical Characterization: The formulations were evaluated for uniformity of weight, thickness, drug content, disintegration time, and mechanical strength (hardness and friability). Scanning electron microscopy (SEM) was used to analyze the structural morphology.
• Taste Assessment: The effectiveness of the taste-masking was evaluated using three independent methods: in vitro drug release profiling, an electronic tongue (e-tongue) equipped with 16 ion-selective electrodes, and a human sensory panel consisting of six healthy volunteers.

Key Findings

• Physical and Mechanical Properties: The formulations demonstrated appropriate mechanical resistance, uniform drug loading, and consistent weight and thickness. Disintegration times were highly favorable, taking approximately 30 seconds for the tablets and 10 seconds for the lyophilisates.
• Structural Integrity: SEM imaging confirmed that the microparticles remained intact and uncracked within the tablet and lyophilisate matrices when optimal compression forces were applied.
• In Vitro Release: Dissolution testing in a simulated saliva environment (pH 6.8) revealed no release of CET for the first 3 minutes, successfully preventing premature release in the mouth, with complete drug release occurring after 15 minutes.
• E-Tongue Results: The e-tongue’s principal component analysis demonstrated that the chemical profile of the microparticle formulations closely resembled that of a placebo rather than pure CET, objectively confirming effective taste masking during the initial 60 seconds of release.
• Human Sensory Evaluation: The human taste panel reported no bitterness or physical roughness, rating the formulations as pleasant or slightly pleasant.

Conclusion 

The study concludes that microencapsulation with Eudragit E PO via spray-drying effectively masks the bitter taste of cetirizine dihydrochloride. These taste-masked microparticles can be successfully integrated into orally disintegrating tablets and oral lyophilisates, resulting in highly palatable formulations with excellent physical properties and rapid disintegration times.

• The PMO/CNTPE was successfully fabricated by electropolymerizing methyl orange (MO) onto the BCNTPE surface using cyclic voltammetry (CV).
• Field emission scanning electron microscopy (FE-SEM) confirmed that the polymerization process transformed the irregularly scattered MWCNT strands into a uniform, even surface.
• Electrochemical impedance spectroscopy (EIS) verified that the modified PMO/CNTPE possessed a lower charge transfer resistance (10.21 kΩ) compared to the bare electrode (11.77 kΩ), indicating enhanced electronic conductivity.

Sensor Performance and Kinetics

• The optimal conditions for the electro-oxidation of CTZ were achieved using a 0.2 M phosphate buffer saline (PBS) solution at a physiological pH of 7.0.
• The anodic peak current for CTZ at the PMO/CNTPE was approximately ten times greater than the current produced by the bare electrode, showcasing admirable electrocatalytic performance.
• The electrochemical reaction of CTZ was determined to be an adsorption-controlled, irreversible process involving an equal proportion of electrons and hydrogen ions.
• The sensor exhibited a broad linear detection range from 2 µM to 45 µM.
• The device achieved a highly sensitive limit of detection (LOD) of 0.076 µM and a limit of quantification (LOQ) of 0.25 µM.

Reliability and Practical Applications

• The modified electrode demonstrated excellent repeatability with a relative standard deviation (RSD) of 1.58%.
• It also showed superior reproducibility, yielding an RSD of 2.22% across five independently prepared electrodes.
• The sensor maintained strong long-term stability, retaining 88.84% of its initial peak current after one week of continuous testing.
• The PMO/CNTPE proved capable of simultaneously detecting CTZ and paracetamol (PCM), two drugs that frequently coexist in medicinal formulations.
