Aims:
The role of craving for alcohol as a response to alcohol treatment is not well understood. We examined daily diary ratings of craving over the course of 28 days among individuals participating in an inpatient substance abuse treatment program.
Methods:
Participants were alcohol dependent patients (n = 100) in the Hazelden residential treatment program who were offered and agreed to take naltrexone and an age- and gender-matched comparison group (n = 100) of alcohol-dependent patients in the same program who declined the offer of treatment with naltrexone. Changes in craving over time were compared between the two groups.
Results:
The naltrexone-treated group reported a more rapid decrease in craving than the usual care group.
Conclusions:
The change in the trajectory of craving is consistent with prior reports suggesting that craving reduction is a mechanism of naltrexone's efficacy in treating alcohol dependence. Providing naltrexone to individuals seeking treatment for alcohol dependence may accelerate a reduction in their craving, consistent with a primary target of many addiction treatment programs.
Short Summary:
Craving ratings by 100 residential patients taking naltrexone for alcohol dependence were compared to ratings by 100 patients who did not take naltrexone. Craving for alcohol decreased more rapidly in the patients taking naltrexone. Providing naltrexone to individuals seeking treatment for alcohol dependence may accelerate a reduction in craving, which may benefit treatment efforts.

Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...

As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
01:19Acid Halides to Alcohols: LiAlH4 Reduction
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
