Enthalpy of solution of terfenadine in ethanol/water mixtures

open access: yes, 2020
The enthalpy of solution of terfenadine in ethanol/water mixtures, 0±20.5 wt.% of water was determined by calorimetry. A Sudden increase of 1±2 kJ mol À1 in the enthalpy at a concentration value around 0.01 mol kg À1 is observed.

Calcium Antagonism and Structure-affinity Relationships of Terfenadine, a Histamine H1 Antagonist, and Some Related Compounds

open access: yes, 1993
Calcium channel affinity of terfenadine and its optical isomers was determined by the displacement of [3H]nitrendipine on rat cerebral cortex membranes. Terfenadine showed a pKd of 6·36±0·03 whereas its R(+)-isomer (VUF4567) had a pKd value of 6·39±0·03 ...

Characterization of terfenadine as a model of a hydrophobic amorphous form of a drug and preparation and characterization of some of its derivatives [PDF]

open access: yes, 2003
Terfenadine was used as a model hydrophobic drug from which an amorphous form was prepared by melting followed by slow or quench-cooling. It was not possible to crystallize amorphous terfenadine at elevated RH either in the isothermal microcalorimeter or

Behavioural and immunological effects of the antihistamine terfenadine in olfactory bulbectomized rats

open access: yes
Examined the effects of chronic treatment with non-sedative histamine H-sub-1 receptor antagonist terfenadine on the behavioral and immunological parameters in the olfactory bulbectomized (OB) rat model of depression. OB Sprague-Dawley rats were injected

NMDA receptor dependent and independent components of veratridine toxicity in cultured cerebellar neurons are prevented by nanomolar concentrations of terfenadine

open access: yes, 2000
Exposure of cultured neurons to nanomolar concentrations of terfenadine prevented the NMDA receptor-mediated early appearance (30min.) of toxicity signs induced by the voltage sensitive sodium channel activator veratridine.

CNS Side-effect of Fexofenadine, 180 mg Tablet

open access: yesSiriraj Medical Journal, 1999
Fexofenadine, the derivative of terfenadine, has been shown to produce no side-effect on the heart, not distributed to the central nervous system (CNS), and having high selectivity for peripheral histamine H1-receptors.
