For this reason, early treatment of paracetamol overdose is recommended (Stoelting & Miller 2000). Opioids are absorbed at the opioid receptors of the central nervous system. One of the key issues that happen at the receptors is the absorption of the drug at the cellular membranes (Department of Health 2011). The drug alters interchange of stimuli at the cellular membranes and this causes the transmissions at the central nervous system to be altered. This inhibits pain and other feelings, making the patient to appear numb and docile.
When the individual stops drinking, however, these adaptive changes result in an imbalance in inhibitory and excitatory neurotransmission, resulting in CNS hyperexcitability that produces as alcohol withdrawal (AW) symptoms. This essay will focus on the main inhibitory and excitatory neurotransmission systems and the symptoms produced in AW due to the imbalance in the brain. Followed by outlining other physiological changes alterations that are associated with AW. The primary inhibitory neurotransmitter in the brain is the gamma-aminobutyric acid (GABA), which exerts its effects mainly through the GABAAreceptor. Alcohol exposure results in activation of the GABAAreceptor, which in turn leads to reduced postsynaptic nerve excitability and thus contribute to alcohol’s sedative effects.
Gamma-aminobutyric acid, also known as GABA, acts as a leading inhibitory neurotransmitter in the brain, and exists within the Central Nervous system. The receptors are tightly and compactly dispersed around the areas of the brain that are active in fearful and anxious responses. These areas include the frontal cortex, hippocampus, and amygdala. (Petrovich and Swanson 1997). Benzopdiazepines are a form of pharmacologic treatment, commonly used amongst patients of anxiety, and work at the benzodiazepine receptor.
The nervous system is the area of the body most affected by... ... middle of paper ... ... breathing trouble, and also comas. As with GHB and ecstasy, rohypnol works to destroy the body in the nervous system. Roypnol is a type of benzodiazepine, a sedative or an antianxiety medication. The benzodiazepine interacts with the receptors on neurons in the brain. Roypnol, like GHB targets the neurotransmitter GABA.
When morphine attacks the central and sympathetic nervous systems, many cellular and molecular activities are altered (Chahl 1996). One of the functions that are altered is stimuli detection. Pain and other stimuli are not detected once the drug is taken. In case a patient is suffering from asthma and leukemia, it is advisable not to administer the drug (Jiang & Ma 2007). Leukemia is a disease associated with blood and the effects of morphine on blood are immense, given that the drug attacks the organs dealing in blood circulation (Health Grades 2011).
The discovery of morphine, which occurred in 1803, transformed the medical treatment of pain and chronic diseases (Levinthal, 2005). Morphine, a narcotic or opioid, is widely used in the medical field today and is specifically used therapeutically to treat moderate to severe pain in individuals. The most common routes of administration for morphine are oral and intravenous administration (Angel, Gould, Carey, 1998). Morphine acts by binding to opioid receptors in the brain and thus reduces the perception of pain and emotional responses to pain (Weil and Winifred, 2004). The paper will focus on the therapeutic uses of morphine for individuals.
(1) After opiates bind opiates are bound to the receptor a messanger such as cyclic AMP express the symptoms that are shown. (1) Mechanism of Toxicity Buprenorphine is contraindicated in patients with patients who opiate agnoist hypersensitivity. (1) It has been shown that CNS and repiratory depression macy occur with therapeutic doses of buprenorphine and can increase with ethanol intoxication. (1) Buprenorphine increass the tone and decreases the contractions of smooth muscles of the gastrointestinal tract resulting in constipation. (1) The metabolism of buprenorphine is directed by CYP3A4 isozyme, when administer with protease inhibitors it may decrease the clearance of buprenorphine.
There are many different types of addictive drugs. The text referred to six different categories of drugs based on their affects to the human brain, their overall tendency for abuse, how addictive they generally are, and how dangerously lethal they can be. The text defines them as psychostimulants, sedatives, and hallucinogens. The psychostimulants give an increased feeling of alertness that is often contrasted with the tranquilizing and depressive effects of the sedative-hypnotics. The hallucinogens give visual illusions and hallucinations that are accompanied by psychosis upon occasion.
In Dr. C. George Boeree’s article he writes “Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses.” When a person takes hallucinogens, or any drug, they interrupt the “signals” that are being sent to the synapses. This can be very harmful to your body and your brain. The National Institute on Drug Abuse and abovetheinfluence.com verify that LSD (d-lysergic acid diethylamide), Peyote cactus or Mescaline, Psilocybin (4-phosphoryloxy-N, N-dimethyltryptamine), and PCP (phencyclidine) are the drugs in the hallucinogens category. What are other names for these drugs? All of the hallucinogens have different “street names.” Street names are names that people call these drugs when they are buying or selling the drugs, or talking about the drugs casually.
