DeBakey Veterans Administration Medical Center, Daryl Shorter, M.D., and Professor of Psychiatry, Pharmacology, and Neuroscience at Baylor College of Medicine, Thomas Kosten, M.D., a different class of medicine is currently underway: antidrug vaccines.1 Antidrug vaccines represent the ongoing development of cutting-edge pharmacological options that allow SUD treatment plans to more certainly reduce use of certain substances and establish abstinence and sobriety.1 Shorter and Kosten review antidrug vaccines in their article “Antidrug Vaccines: Fact or Science Fiction?”

autopzionibinarie bufala Abused substances work by acting on the reward and reinforcement pathways of the brain.1 According to Shorter and Kosten, after the substance is introduced to the body—for example by inhalation, intranasal, oral, or intravenous route—they enter the brain and activate certain target neurotransmitters.1 The substances of abuse must be small enough to pass through the blood-brain barrier.1

Antidrug Vaccine: Fiction-Turned-Fact

binäre optionen volatilitätsstrategie While using a vaccine to treat chemical dependencies may sound very science-fiction-like, it may surprise you that they have been in the process of development for many years.1 For example, in 1972, Berkowitz and Spector published a report regarding a morphine vaccine.[2] In rats, the administration of the vaccine resulted in the creation of antimorphine antibodies, which reduced the concentration of the drug in rats and decreased the use of self-administrated heroin in rhesus monkeys.[3] Since then, additional development has been made regarding antidrug vaccines. It has been discovered that the vaccines bind drugs in circulation, reducing euphoric effects and symptoms of toxicity.1 The vaccines produce an active immunization, where the administration of the vaccine produces an immunological response to the agent, and booster injections amplify the initial response.1 Therefore, the immune system is prepared by the initial vaccination, and booster injections produce antibody responses.1 The antibodies bind to the substance of abuse, making it unable to pass through the blood-brain barrier, causing it to become trapped in the circulation system and cleared from the body.1 The individual will also no longer feel the euphoric effects of the substance.1

The vaccine is currently undergoing a large-scale phase 2b clinical study.1

Higher quit-rates were seen with TA-NIC.1
