  • Image not available. Pharmacogenomic studies have identified genotypic and functional phenotypic variants that either serve to protect patients or predispose them toward alcohol dependence.

  • Image not available. Except at very high and very low blood concentrations, the metabolism of alcohol is considered to follow zero-order pharmacokinetics, and this has important implications for the time course in which alcohol can exert its effects.

  • Image not available. Disulfiram, naltrexone, and acamprosate are FDA-approved drug therapies for the treatment of alcohol dependence. The clinical utility of these agents to improve sustained abstinence remains controversial. Relapse is common.

  • Image not available. More than three quarters of smokers are nicotine dependent. Tobacco dependence is a chronic condition that requires repeated interventions.

  • Image not available. A systematic Cochrane review completed in 2012 showed all forms of nicotine replacement therapy were effective in reducing the amount smoked and achieving abstinence.

  • Image not available. Caffeinism is the term coined to describe the clinical syndrome produced by acute or chronic overuse of caffeine. As many as one in five adults consume doses of caffeine generally considered large enough to cause clinical symptoms.

Image not available. In 2013, heavy drinking was reported by 6.3% of the population aged 12 or older, or 16.5 million people.2 Approximately one quarter (22.9%) of persons aged 12 or older participated in binge drinking at least once in the 30 days prior to the National Survey on Drug Use and Health (NSDUH) in 2013 which is very similar to the 23% reported in 2012.2 The World Health Organization estimates that in 2012, there were approximately 3.3 million people worldwide who died from alcohol consumption.3 Long-term alcohol abuse often leads to chronic disease. A causal relationship between alcohol abuse and at least 200 types of chronic disease or ...
