Higher doses of celecoxib, diclofenac, duloxetine, and fluoxetine were required to attenuate von Frey-evoked mechanical allodynia. In the side effect assays, only fluoxetine decreased locomotor activity

at doses used in PEAR These results show that in inflammatory pain induced by CFA injection, PEAP is more sensitive to the effects of pain relieving compounds than mechanical allodynia. Fluoxetine showed efficacy in the mechanical allodynia test, but not PEAR, whereas duloxetine showed efficacy in mechanical allodynia and PEAR These studies show that methods other than reflex based measures of pain such as affective pain models could be more predictive of efficacy/potency in the clinic.

“Background Addiction to PSI-7977 concentration heroin and crack cocaine is debilitating and persistent, but such disorders are treatable. We present the first effectiveness study of the main community interventions for addiction to heroin and crack cocaine in England, using data from the National Drug Treatment Monitoring System (NDTMS).

Methods The study cohort consisted of all adults with a heroin or crack cocaine addiction, or both, who Sapanisertib purchase started pharmacological treatment (n=18428 patients) or psychosocial treatment (n=2647) between Jan 1 and Nov 30, 2008, received at least 6 months’ treatment or were discharged

by the study endpoint (May 31, 2009), and had outcome data submitted to the NDTMS. Effectiveness was assessed from Carbachol change in days of heroin or crack cocaine use, or both in the 28 days before the start of treatment and in the 28 days before review.

Findings 14656 clients-74% of the cohort eligible for analysis at review with available data-were analysed at the study endpoint. During the 28 days before review, 37% (5016/13 542) of heroin users abstained from heroin and 52% (3941/7636) of crack cocaine users abstained from crack cocaine. A higher proportion of users of heroin only abstained than did users of both heroin and crack cocaine (42%

[2465/5863] vs 33% [2551/7679]; OR 1.46, 95% CI 1.36-1.56), and more users of crack cocaine only abstained than did users of both drugs (57% [295/522] vs 51% [3646/7114]; 1.24, 1.03-1.48). Overall heroin use reduced by 14.5 days (95% CI 14.3-14.7) and crack cocaine use by 7.7 days (7.5-7.9). For clients given pharmacological treatment, reduction in days of heroin use was smaller for users of both heroin and crack cocaine than for users of heroin alone (p<0.0001), but this differential effectiveness was not recorded for psychosocial treatment in heroin or crack cocaine users compared with users of both drugs.

Interpretation The first 6 months of pharmacological or psychosocial treatment is associated with reduced heroin and crack cocaine use, but the effectiveness of pharmacological treatment is less pronounced for users of both drugs.
