Niguldipine, a mixture of two forms: (-) and (+)-Niguldipine is an antagonist of alpha 1A adrenoreceptors. Preclinical studies of niguldipine as an anticonvulsive drug on mice was revealed that the use of niguldipine in epileptic patients seems questionable.

Sample Use Guides

In Vivo Use Guide

in mice: niguldipine (up to 2.5 mg/kg) did not influence the electroconvulsive threshold in mice, although a higher dose of niguldipine (5 mg/kg) significantly elevated it.

Route of Administration: Oral

In Vitro Use Guide

The effect of increasing concentrations of daunomycin on the inhibition of cell growth in MCF-7/adr cells was examined in the absence and presence of the 4-aryl-1,4-dihydropyridines (Ia-q) and 4-arylpyridines (IIa-q). The control studies were performed using the vehicle (0.1% DMSO), whereas niguldipine (3 μM) served as a positive control. All of the compounds that significantly increased vinblastine accumulation were able to significantly decrease the IC50 values of daunomycin. If, Ih1, and Ih2, which did not affect drug accumulation, also did not lower the IC50 of daunomycin when compared with the control.
