Evaluation of Pharmacokinetics of a BCS Class III Drug with Two Different Study Designs: Tenofovir Alafenamide Monofumarate Film-coated Tablet.

Tenofovir alafenamide (TAF) is a BCS Class III compound and an oral pro-drug of Tenofovir (TFV) with limited oral bioavailability. The bioavailability of the oral intake increases with food as a result of the low stability of the active substance in the stomach. The reference drug is "Vemlidy® 25 mg Film Tablet", which contains 25 mg of TAF in "hemifumarate" form, is under patent protection until 15.

Cell culture and pharmacokinetic evaluation of a solid dosage formulation containing a water-insoluble orphan drug manufactured by FDM-3DP technology.

The in-vitro cytotoxicity, in-vitro permeability and in-vivo pharmacokinetics of a BCS Class-II drug - rufinamide - in a 3DP tablet formulation were evaluated. The cytotoxicity of the 3DP tablet formulation was evaluated with an MTT test; in-vitro permeability was evaluated with a Caco-2 cell culture study; and in-vivo pharmacokinetics were evaluated in Wistar albino male rats. The pharmacokinetic studies were performed following a two-sequence and single-period design approach.

A Study to Compare Bioequivalence Approach Between FDA and EMA in a Highly Variable Drug: Pinaverium Bromide Film Tablets.

The aim of this study is to investigate pharmacokinetic parameters of test and reference film tablet formulations of a highly variable drug, pinaverium bromide, under fasting conditions and to assess their bioequivalence in accordance with the FDA and EMA criteria. A randomised open-label, single oral dose, three-sequence, three-period, semi-replicated, cross-over trial was conducted with 36 healthy subjects. The intrasubject variability of reference products for C and AUC was found to be more than 50%.

Improving the dissolution of a water-insoluble orphan drug through a fused deposition modelling 3-Dimensional printing technology approach.

Lennox-Gastaut Syndrome (LGS) is a rare form of childhood epilepsy. Rufinamide is an orphan drug indicated for the treatment of LGS. Three-Dimensional Printing (3DP) is a process in which solid objects are created based on a digital file by adding materials layer by layer.

Development and in vitro evaluation of pH-independent release matrix tablet of weakly acidic drug valsartan using quality by design tools.

The main objective of this study was the development of pH-independent controlled release valsartan matrix tablet in Quality by design (QbD) framework. The quality target product profile (QTPP), critical quality attributes (CQAs) and critical material attributes (CMAs) were defined by science and risk-based methodologies. Potential risk factors were identified with Fishbone diagram.
