Efficacy of duloxetine, a potent and balanced serotonin-norepinephrine reuptake inhibitor in persistent pain models in rats

Abstract: 5-Hydroxytryptamine (serotonin) (5-HT) and norepinephrine (NE) are implicated in modulating descending inhibitory pain pathways in the central nervous system. Duloxetine is a selective and potent dual 5-HT and NE reuptake inhibitor (SNRI). The ability of duloxetine to antagonize 5-HT depletion in para-chloramphetamine-treated rats was comparable with that of paroxetine, a selective serotonin reuptake inhibitor (SSRI), whereas its ability to antagonize NE depletion in alpha-methyl-m-tyrosine-treated rats was similar to norepinephrine reuptake inhibitors (NRIs), thionisoxetine or desipramine. In this paradigm, duloxetine was also more potent than other SNRIs, including venlafaxine or milnacipran and amitriptyline. Low doses of the SSRI paroxetine or the NRI thionisoxetine alone did not have an effect on late phase paw-licking pain behavior in the formalin model of persistent pain; however, when combined, significantly attenuated this pain behavior. Duloxetine (3-15 mg/kg intraperitoneal) significantly attenuated late phase paw-licking behavior in a dose-dependent manner in the formalin model and was more potent than venlafaxine, milnacipran, and amitriptyline. These effects of duloxetine were evident at doses that did not cause neurologic deficits in the rotorod test. Duloxetine (5-30 mg/kg oral) was also more potent and efficacious than venlafaxine and milnacipran in reversing mechanical allodynia behavior in the L5/L6 spinal nerve ligation model of neuropathic pain. Duloxetine (3-30 mg/kg oral) was minimally efficacious in the tail-flick model of acute nociceptive pain. These data suggest that inhibition of both 5-HT and NE uptake may account for attenuation of persistent pain mechanisms. Thus, duloxetine may have utility in treatment of human persistent and neuropathic pain states.

A New Paradigm for Type 2 Diabetes Mellitus: Could It Be a Disease of the Foregut?

Abstract: Summary Background DataWe previously reported, in a study of 608 patients, that the gastric bypass operation (GB) controls type 2 diabetes mellitus in the morbidly obese patient more effectively than any medical therapy. Further, we showed for the first time that it was possible to reduce the mo

Teriparatide effects on vertebral fractures and bone mineral density in men with osteoporosis: treatment and discontinuation of therapy.

Abstract: Teriparatide (rhPTH[1-34]), a bone-forming agent for the treatment of osteoporosis, increases bone mineral density in men and women, and reduces the risk of fractures in women with osteoporosis. However, fracture efficacy has not yet been confirmed in men. Further, there is limited information on the effect of withdrawal of teriparatide. The purpose of this manuscript is to report on bone mineral density and vertebral fracture incidence during a 42-month observation period, from the baseline of the previously reported treatment study in men [1] through 30 months of posttreatment follow-up. Three hundred fifty-five men who were treated with once-daily self-injections of either placebo or 20 or 40 µg of teriparatide participated in the follow-up study. Bone mineral density gradually decreased following discontinuation of teriparatide therapy. However, the lumbar spine and total hip values remained significantly higher than baseline after 30 months of follow-up (p≤0.001). Antiresorptive treatment prevented the decline and tended to further increase bone mineral density. Lateral thoracic lumbar radiographs obtained at baseline and 18 months after discontinuation of teriparatide were available for 279 men. Of these men, 11.7% assigned to placebo, 5.4% treated with teriparatide 20 µg, and 6.0% treated with teriparatide 40 µg had an incident vertebral fracture. In the combined teriparatide treated groups vs placebo, the risk of vertebral fracture was reduced 51% (nonsignificant, p=0.07). The incidence of moderate or severe fractures was significantly reduced by 83% (p=0.01). In conclusion, men who received teriparatide and who may have received follow-up antiresorptive therapy had a decreased risk of moderate and severe vertebral fractures.
