Caffeine augments Alprazolam induced cytotoxicity in human cell lines.

Sunday, May 30th, 2010

Authors: Saha B, Mukherjee A, Samanta S, Saha P, Ghosh AK, Santra CR, Karmakar P
Combined effects of alprazolam (Alp), a member of benzodiazepine group of drugs and caffeine on human cell lines, HeLa and THP1 were investigated in this stu dy. Alp mediated cytotoxicity was enhanced while caffeine was present. The cell death was confirmed by observing morphological changes, LDH assay and membrane anisotropic study. Also such combined effects (more…)

Vardenafil Increases Cell Proliferation in the Dentate Gyrus through Enhancement of Serotonin Expression in the Rat Dorsal Raphe.

Friday, May 28th, 2010

This study was conducted to evaluate the effects of vardenafil (Levitra), a phosphodiesterase-5 (PDE-5) inhibitor, on cell proliferation in the hippocampal dentate gyrus and on 5-hyroxytryptamine (5- HT, serotonin) synthesis and tryptophan hydroxylase (TPH) expression in the rat dorsal raphe nucleus. Male Sprague-Dawley rats were divided into 6 groups (n=5 in each group): a control group, a 0.5 mg/kg-1 day vardenafil-treated grou p, a 1 mg/kg-1 (more…)

Benzodiazepines medazepam and midazolam are activators of pregnane X receptor and weak inducers of CYP3A4: Investigation in primary cultures of human hepatocytes and hepatocarcinoma cell lines.

Friday, May 21st, 2010

In conclusion, Alprazolam, Bromazepam, Chlordiazepoxide, Clonazepam, Di azepam, Lorazepam, Nitrazepam, Oxazepam, Tetrazepam and Triazolam can be considered as safe drugs in term of their inability to induce PXR- and AhR-dependent cytochrome P450 enzymes CYP1A2 and CYP3A4. Medazepam and Midazolam slightly activated pregnane X receptor and displayed weak potency to induce CYP3A4 mRNA in human hepatocytes.
