Mucociliary clearance is composed of three components (i.e., mucin secretion, airway surface hydration, and ciliary-activity) which function coordinately to clear inhaled microbes and other foreign particles from airway surfaces.

In Silico Absorption Analysis of Valacyclovir in Wildtype and Pept1 Knockout Mice Following Oral Dose Escalation

In Silico Absorption Analysis of Valacyclovir in Wildtype and Pept1 Knockout Mice Following Oral Dose Escalation

Authors: Yang B, Smith DE
Publication: Pharm Res
Software: GastroPlus®

We developed simulation and modeling methods to predict the in vivo pharmacokinetic profiles of acyclovir, following escalating oral doses of valacyclovir, in wildtype and Pept1knockout mice.

Lipophilic salts of poorly soluble compounds to enable high-dose lipidic SEDDS formulations in drug discovery

Lipophilic salts of poorly soluble compounds to enable high-dose lipidic SEDDS formulations in drug discovery

Publication: Eur J Pharm Biopharm
Software: GastroPlus®

Self-emulsifying drug delivery systems (SEDDS) have been used to solubilize poorly water-soluble drugs to improve exposure in high-dose pharmacokinetic (PK) and toxicokinetic (TK) studies.

In silico prediction of skin metabolism and its implication in toxicity assessment

In silico prediction of skin metabolism and its implication in toxicity assessment

Publication: Computational Toxicology
Software: ADMET Predictor®

Skin, being the largest organ of the body, represents an important route of exposure, not only for the abundance of chemicals present in the environment, but also for...

Integrating in vitro, modeling, and in vivo approaches to investigate warfarin bioequivalence

Integrating in vitro, modeling, and in vivo approaches to investigate warfarin bioequivalence

Publication: CPT Pharmacometrics Syst Pharmacol
Software: GastroPlus®

We demonstrate the use of modeling and simulation to investigate bioequivalence concerns raised about generic warfarin products.

Identification and characterisation of a salt form of Danirixin with reduced pharmacokinetic variability in patient populations

Identification and characterisation of a salt form of Danirixin with reduced pharmacokinetic variability in patient populations

Publication: Eur J Pharm Biopharm
Software: GastroPlus®

The natural variability of gastric pH or gastric acid reducing medications can result in lower and more variable clinical pharmacokinetics for basic compounds in patient populations.

Calcium Phosphate Particles as Pulmonary Delivery System for Interferon-α in Mice

Calcium Phosphate Particles as Pulmonary Delivery System for Interferon-α in Mice

Publication: AAPS PharmSciTech
Software: GastroPlus®

Systemically administered interferons are rapidly cleared from the circulation thus requiring frequent dosing to maintain the therapeutic levels of circulating interferon.

Utility of Physiologically Based Pharmacokinetic Absorption Modeling to Predict the Impact of Salt-to-Base Conversion on Prasugrel HCl Product Bioequivalence in the Presence of Proton Pump Inhibitors

Utility of Physiologically Based Pharmacokinetic Absorption Modeling to Predict the Impact of Salt-to-Base Conversion on Prasugrel HCl Product Bioequivalence in the Presence of Proton Pump Inhibitors

Authors: Fan J, Zhang X, Zhao L
Publication: AAPS J

Prasugrel HCl may convert to prasugrel base during manufacturing or storage. It was reported that formulations with different ratios of salt to base were bioequivalent in healthy subjects...
