Modern concepts of addictive disorders emphasize the compulsive and relapsing drug-taking behaviors rather than tolerance and physical dependence. As with any chronic disorder, long-term treatment is necessary and medications may aid in the rehabilitative process. Specific medications have been demonstrated to be helpful for psychiatric disorders coexisting with addiction. Medications have also been demonstrated in controlled studies to aid in the rehabilitation of patients dependent on nicotine, alcohol, or opiates. Thus far, no medication has been clearly demonstrated to benefit patients suffering from abuse or dependence on cocaine, cannabinoids, nonalcohol sedatives, or hallucinogens.

Less than one third of people afflicted with generalized anxiety disorder (GAD) experience spontaneous remission, and the symptoms of GAD wax and wane throughout a person's life. The burden of GAD may be reduced with psychopharmacologic therapy. The medications with the most evidence of efficacy in GAD are the benzodiazepines, including a new long-acting formulation of alprazolam. These drugs have a low incidence of side effects but may cause physical dependence, withdrawal, and sedation. Antidepressants are also efficacious in GAD but act less quickly than benzodiazepines. Tricyclic antidepressants such as imipramine may substantially reduce symptoms of anxiety but are not considered a first-line therapy because of their side effects spectrum. The extended-release formulation of venlafaxine and selective serotonin reuptake inhibitors such as paroxetine and sertraline are also efficacious in GAD. While their association with sexual dysfunction may be intolerable for some adults, these drugs may be more appropriate than the benzodiazepines because their chronic use does not lead to dependence. Buspirone also significantly reduces symptoms of GAD and is associated with less sexual dysfunction than SSRIs and less sedation than benzodiazepines. Combining antidepressant and benzodiazepine therapy or medication treatment and psychotherapy may lead to an increase in improvement in patients not responding to 1 treatment approach alone. The most effective treatment for managing the recurrent symptoms of this chronic disorder will remain unknown until more long-term studies using both drug and nondrug therapies are conducted. Remission rates are still only about 40%, signifying the need for improved treatment interventions.

Addicts have an exaggerated organic and psychological comorbidity and in cases of major operations or polytrauma they are classified as high-risk patients. Additional perioperative problems are a higher analgetics requirement, craving, physical and/or psychological withdrawal symptoms, hyperalgesia and tolerance. However, the clinical expression depends on the substance abused. For a better understanding of the necessary perioperative measures, it is helpful to classify the substances into central nervous system depressors (e.g. heroin, alcohol, sedatives, hypnotics), stimulants (e.g. cocaine, amphetamines, designer drugs) and other psychotropic substances (e.g. cannabis, hallucinogens, inhalants). The perioperative therapy should not be a therapy for the addiction, as this is senseless. On the contrary, the characteristics of this chronic disease must be accepted. Anesthesia and analgesia must be generously stress protective and sufficiently analgesically effective. Equally important perioperative treatment principles are stabilization of physical dependence by substitution with methadone (for heroin addicts) or benzodiazepines/clonidine (for alcohol, sedatives and hypnotics addiction), avoidance of stress and craving, thorough intraoperative and postoperative stress relief by using regional techniques or systematically higher than normal dosages of anesthetics and opioids, strict avoidance of inadequate dosage of analgetics, postoperative optimization of regional or systemic analgesia by non-opioids and coanalgetics and consideration of the complex physical and psychological characteristics and comorbidities. Even in cases of abstinence (clean) an inadequate dosage must be avoided as this, and not an adequate pain therapy sometimes even with strong opioids, can potentially activate addiction. A protracted abstinence syndrome after withdrawal of opioids can lead to increased response to administered opioids (e.g. analgesia, side-effects).

Anxiety disorders are persistent impairing diseases, with often chronic course and suffering from symptoms throughout a life-span. The medication with the most evidence of efficacy is the benzodiazepines having a low incidence of side effects but may cause physical dependence, withdrawal and sedation. The use of these drugs should be limited to the acute treatments during the first several weeks in combination with an SSRI or and SNRI for the treatment of the acute phase. After three to four weeks, when antidepressants become effective, benzodiazepine dose should be tapered over a one week period. Among the antidepressants, the SSRI and the SNRI are considered a first-line therapy because of their favourable side effect spectrum compared to tricyclic antidepressants. However, the association with side effects such as nausea, sweating, sexual dysfunction and gastrointestinal problems and insomnia may be intolerable for a number of patients. Combining antidepressants and benzodiazepine therapy or medication treatment and psychotherapy may lead to an increase in improvement in patients not responding to one treatment approach alone. The most effective treatment for managing the recurrent symptoms of this chronic disorder are still unknown and other studies and approaches are in need as remission rates are still only about 40%.

Drug addicts need special anesthesiological care due to their co-morbidities, their modified need for analgesics and anesthetics and/or their specific substitution therapies. In spite of the high incidence of addiction worldwide controlled studies and evidence based recommendations for the anaesthesiological management of the patients are missing. The perioperative care is not the treatment of addiction, on the contrary the specific aspects of a chronic disease have to be accepted. Equally important perioperative treatment strategies for the management of drug addicts include: 1. stabilisation of the physical dependence by substitution therapies. 2. avoidance of distress or craving. 3. perioperative stress relief. 4. strict avoidance of inadequate analgesic treatment. 5. postoperative optimization with regional or systemic analgesia with non-opioids, opiods and co-analgesics. 6. consideration of specific physical or psychological comorbidities. Inadequate analgesic treatment is known to be responsible for relapses into addiction and has strictly to be avoided. This holds true even for people with long term drug abstinence.
