Modeling picking on pharmaceutical tablets
<p>Tablets are the most popular solid dosage form in the pharmaceutical industry because they are cheap to manufacture, chemically and mechanically stable and easy to transport and fairly easy to control dosage. Pharmaceutical tableting operations have been around for decades however the process is …

Exploring Thumb Input on Flexible Tablets
Flexible displays offer new interaction techniques such as bend gestures, but little work has been done to support touch input. Touch is the most common input method for handheld devices. We explore the potential of touch input using the thumb of the holding hand on flexible displays. We conducted …

Geometric modelling and shape optimisation of pharmaceutical tablets. Geometric modelling and shape optimisation of pharmaceutical tablets using partial differential equations.
Pharmaceutical tablets have been the most dominant form for drug delivery and they need to be strong enough to withstand external stresses due to packaging and loading conditions before use. The strength of the produced tablets, which is characterised by their compressibility and compactibility, is …

Formulation and evaluation of diclofenac sodium dispersible tablets
… Many patients have difficulty swallowing tablets and consequently do not take medication as prescribed. To achieve optimum benefit of a drug, it is desirable to present it in a formulation which can rapidly disperse in water. This formulation is easier to swallow, therefore enhancing …

The surface characterisation of pharmaceutical mini-tablets using thermal probe techniques
… across the surface of pharmaceutical mini-tablets. Such information is of use in formulation development, as the surface is the point at which a solid dosage form comes into contact with the environment, and where drug stability and excipient functionality are critical. Mini-tablets provide …

Predictive Disintegration Process Modelling of Immediate Release Tablets Using Terahertz Technology
… Predicting disintegration for immediate-release tablets remains challenging due to the process complexity. This research addresses this by establishing a predictive and mechanistic framework based on terahertz (THz) characterisation and physics-informed modelling. This model aims to reduce …

Investigating the Hydration and Disintegration Mechanisms of Film-Coated Pharmaceutical Tablets
… pharmaceutical ingredient (API) to patients. Tablets are often film-coated with a layer of polymeric material to protect the drug from environmental degradation, facilitate the packaging process, and enhance patient compliance. However, the mechanisms of hydration, disintegration and …

Design de Informação em produtos jornalísticos para tablets: uma comparação Brasil-Espanha
… decorrentes das funcionalidades incorporadas aos tablets. A partir de uma análise de caráter exploratório, buscamos entender as peculiaridades, os pontos recorrentes e as rupturas trazidas na forma de sintagmas e sintaxes de interação, constituintes de uma nova gramática visual. Em segundo lugar, …

Development of Sodium Benzoate Tablets with Dual Burst Release: Hydrophilic Matrix System
… dosing frequency. To achieve dual burst release, tablets with hydrophilic matrix system were developed. These tablets consist of a hydrophilic matrix system that incorporates the API. The hydrophilic polymers swell up and function as a barrier and control the release of the API. A total of 27 …

Characterisation of freeze dried amino acids and gelatin based rapidly Disintegrating tablets
Recent research has shown the feasibility of using individual or a combination of amino acids as a replacement component for sugars in RDT formulations. What has emerged from this work is the notion of an optimal concentration of amino acid, i.e. one that is sufficiently high to provide the desired …

Development of Co-processed Plasticized Cellulose Acetate for Sustained Release Matrix Tablets
… polymer candidate for sustained release matrix tablets. Sustained release matrix tablets of cellulose acetate can be prepared by direct compression or wet granulation methods. However, previous studies showed that a large amount of CA was required to achieve the desired sustained release profile …

Characterisation of Tablets and Roller-Compacted Ribbons with Terahertz Time-Domain Pulsed Imaging
… to test the solid-fraction ratios of pharma tablets with regard to RI’s being surrogate values to SF/path-length (R2 = 1). Combining transmission principles to the portion of reflected EMR removes the pre-requisite for RI or path-length knowledge, giving +1.5 to +2.4% RI agreement (vs. …

TabletGaze: Dataset and Algorithm for Unconstrained Appearance-based Gaze Estimation in Mobile Tablets
In this thesis, we study gaze estimation on tablets. Our key design goal is uncalibrated gaze estimation using the front-facing camera during natural use of tablets, where the posture and method of holding the tablet is not constrained. We collected the first large unconstrained gaze dataset of …

The formulation and stability of dispersible or chewable tablets containing anti retroviral drugs
… of these drugs in single or dual-therapy include tablets, coated tablets and oral solutions. Three problem areas are currently experienced with the above mentioned dosage forms. Firstly tablets and coated tablets, although they provide good stability and therefore shelf life, cannot be easily …

Activation of Release by Hydration in Pharmaceutical Tablets Studied by Terahertz Pulsed Imaging
Tablets are one of the most common pharmaceutical dosage forms. The liquid ingress into a tablet is considered to be the first, and often rate-determining, step for tablet disintegration and subsequent drug dissolution. Even for tablets that do not disintegrate (e.g. sustained release tablets), …
