Hallucination

The reasons Strike wrote this book. The reasons you re reading this book. Ecstasy is the most benign drug Strike has ever encountered. It is passive yet powerful. By powerful Strike does not mean that it incapacitates or makes one dangerous. It is, in fact, quite the opposite. Its power is in its ability to evoke a total sensory bath of tactile, visual and mental enhancement. One s perception is perfectly clear. Hallucinations are nonexistent. The feeling one has is, literally, ecstasy. Plus, it is one of the few narcotics in the world that is not physically addictive. Why this substance was taken away from the people is a question that only government-funded scientists can answer. 

Crude preparations of mescaline (61) from peyote were first reported by the Spanish as they learned of its use from the natives of Mexico during the Spanish invasion of that country in the sixteenth century. The colorful history (44) of mescaline has drawn attention to its use as a hallucinogen and even today it is in use among natives of North and South America. Although in connection with dmg abuse complaints, mescaline is considered dangerous, it has been reported (45) that it is not a narcotic nor is it habituating. It was also suggested that its sacramental use in the Native American Church of the United States be permitted since it appears to provoke only visual hallucination while the subject retains clear consciousness and awareness. 

Manufacture, Shipment, and Analysis. In the United States, sodium and potassium thiocyanates are made by adding caustic soda or potash to ammonium thiocyanate, followed by evaporation of the ammonia and water. The products are sold either as 50—55 wt % aqueous solutions, in the case of sodium thiocyanate, or as the crystalline soHds with one grade containing 5 wt % water and a higher assay grade containing a maximum of 2 wt % water. In Europe, the thiocyanates may be made by direct sulfurization of the corresponding cyanide. The acute LD q (rat, oral) of sodium thiocyanate is 764 mg/kg, accompanied by convulsions and respiratory failure LD q (mouse, oral) is 362 mg/kg. The lowest pubhshed toxic dose for potassium thiocyanate is 80—428 mg/kg, with hallucinations, convulsions, or muscular weakness. The acute LD q (rat, oral) for potassium thiocyanate is 854 mg/kg, with convulsions and respiratory failure. 

Another injectable anesthetic widely used in feline and primate practice is ketamine hydrochloride [1867-66-9]. Ketamine, a derivative of phencychdine, can be chemically classified as a cyclohexamine and pharmacologically as a dissociative agent. Analgesia is produced along with a state that resembles anesthesia but in humans has been associated with hallucinations and confusion. For these reasons, ketamine is often combined with a tranquilizer. The product is safe when used in accordance with label directions, but the recovery period may be as long as 12—24 h. 

Neurological symptoms result from demyelination of the spinal cord and are potentially irreversible. The symptoms and signs characteristic of a vitamin B 2 deficiency include paresthesis of the hands and feet, decreased deep-tendon reflexes, unsteadiness, and potential psychiatric problems such as moodiness, hallucinations, delusions, and psychosis. Neuropsychiatric disorders sometimes develop independently of the anemia, particularly in elderly patients. Visual loss may develop as a result of optic atrophy. 

The Class I agents have many similar side effects and toxicities. The anticholinergic side effects include dry mouth, constipation, and urinary hesitancy and retention. Common gastrointestinal (GI) side effects include nausea, vomiting, diarrhea, and anorexia. Cardiovascular adverse effects are hypotension, tachycardia, arrhythmias, and myocardial depression, especially in patients with congestive heart failure. Common central nervous system (CNS) side effects are headache, dizziness, mental confusion, hallucinations, CNS stimulation, paraesthesias, and convulsions. 

Toxic effects of propranolol are related to its blocking P-adrenoceptor blocking actions. They include cardiac failure, hypotension, hypoglycemia, and bronchospasm. Propranolol is lipophilic and crosses the blood—brain barrier. Complaints of fatigue, lethargy, mental depression, nightmares, hallucinations, and insomnia have been reported. GI side effects include nausea, vomiting, diarrhea, and constipation (1,2). 

Zipeprol [34758-83-3] (58) is another European antitussive with a wide range of pharmacological effects, including antispasmodic, antihistaminic, and local anesthetic activities (85,86). It has been reported that zipeprol has been abused in Italy because high doses cause hallucinations (87). Spontaneous withdrawal symptoms similar to those of opiates have been observed withdrawal symptoms can also be precipitated by naloxone. Zipeprol can be... 

Psychoses. Major thought disorders involving distorted perception and hallucinations. 

The abstinence syndrome (synonym, withdrawal symptom) is observed after withdrawal of a dtug to which a person is addicted. For example, the abstinence syndrome after alcohol withdrawal is characterized by tremor, nausea, tachycardia, sweating and sometimes hallucinations. 

Affective (mood) disorders are characterized by changes in mood. The most common manifestation is depression, arranging from mild to severe forms. Psychotic depression is accompanied by hallucinations and illusions. Mania is less common than depression. In bipolar affective disorder, depression alternates with mania. 

Dementia with Lewy bodies (DLB) is considered the second most common cause of dementia after AD. The disorder is characterized by progressive fluctuating cognitive impairment, visual hallucinations and motor features of Parkinsonism. Neocoitical cholinergic activity is more severely depleted in DLB than in AD, and DLB also affects the caudate nucleus, the thalamus and the brain stem. Tolerability of ChEI in DLB appears similar to AD, with some gastrointestinal effects and muscle cramps. 

Parkinson s disease (PD) patients may suffer cognitive and behavioural impairments including apathy, personality changes and visual hallucinations, with no currently recommended treatment. Their significant cholinergic deficits led to recommendation of ChEI therapeutics. 

Methylenedioxymethamphetamine (MDMA ecstasy) is a synthetic analog of amphetamine that produces hallucinations, an elevation in mood, and a feeling of emotional closeness . This latter property has led to Ecstasy being referred to as the hug drag . The unique properties of Ecstasy as compared to the parent compound amphetamine are believed to be due to the more selective effects of Ecstasy in promoting transporter-mediated release of serotonin. The use of Ecstasy has become a part of the culture associated with rave style dance parties. 

Neuroleptics or antipsychotics suppress the positive symptoms of schizophrenia such as combativeness, hallucinations and formal thought disorder. Some also alleviate the negative symptoms such as affective blunting, withdrawal and seclusiveness. Neuroleptics also produce a state of apathy and emotional indifference. Most neuroleptics block dopamine D2-receptors but some, like clozapine, also block dopamine D4-receptors or serotonin 5-hydroxytryptamine2A-receptors. 

Psychotomimetic drags can be defined as chemical agents that reliably and dose-dependently induce a psychosis, often including hallucinations and delusions in normal individuals. Implicit in this term is a mimicking of naturally occulting psychosis. 

The postulation of a possible role of trace amines in the context of schizophrenia was kindled early on by the structural similarity between PEA and amphetamine. Symptoms such as hallucinations and paranoid episodes caused by a prolonged amphetamine intoxification are reminiscent of patients suffering from acute schizophrenia. Further support for a role of trace amines in the context of schizophrenia comes from clinical studies...

Psychomotor seizures occur most often in children 3 years of age through adolescence. The individual may experience an aura with perceptual alterations, such as hallucinations or a strong sense of fear. Repeated coordinated but inappropriate movements,... 

The most common serious adverse reactions to amantadine are orthostatic hypotension, depression, congestive heart failure, psychosis, urinary retention, convulsions, leukopenia, and neutropenia Less serious reactions include hallucinations, confusion, anxiety, anorexia, nausea, and constipation. Adverse reactions with selegiline include nausea, hallucinations, confusion, depression, loss of balance, and dizziness. 

The adverse reactions most often associated with the administration of the COMT inhibitors include disorientation, confusion, light-headedness, dizziness, dyskinesias, hyperkinesias, nausea, vomiting, hallucinations, and fever. Other adverse reactions are orthostatic hypotension, sleep disorders, excessive dreaming, somnolence, and muscle cramps. A serious and possibly fatal adverse reaction that can occur with the administration of tolcapone is liver failure... 

The most common adverse reactions seen with pramipexole and ropinirole include nausea, dizziness, postural hypotension, hallucinations, somnolence, vomiting, confusion, visual disturbances, abnormal involuntary movements, and headache... 

There is an increased risk of CNS depression when tiie dopamine receptor agonists are administered witii otiier CNS depressants. When administered witii levodopa, the dopamine receptor agonists increase the effects of levodopa (a lower dosage of levodopa may be required). hi addition, when the dopamine receptor agonists are administered with levodopa, there is an increased risk of hallucinations. When administered witii ciprofloxacin, there is an increased effect of the dopamine receptor agonist. 

Some patients with parkinsonism communicate poorly and do not tell the primary health care provider or nurse that problems are occurring. The nurse observes the patient with parkinsonism for outward changes that may indicate one or more adverse reactions. For example a sudden change in the facial expression or changes in posture may indicate abdominal pain or discomfort, which may be caused by urinary retention, paralytic ileus, or constipation. Sudden changes in behavior may indicate hallucinations, depression, or other psychotic episodes. 

Hallucinations occur more often in the older adult than in the... 

I younger adult receiving the antiparkinsonism drugs especially when taking the dopamine receptor agonists The nurse should assess the older adult for sgns of visual, auditory, or tactile hallucinations The incidence of halludnationsappears to increase with age.
