Oculogyric Crises
Oculogyric crisis (OGC) is a rare sudden, paroxysmal, dystonic reaction that may manifest in response to specific drugs, particularly neuroleptics, or medical conditions, such as movement disorders. This neurological phenomenon is characterized by a sustained dystonic, conjugate, involuntary upward deviation of both eyes lasting seconds to hours. The term ''oculogyric'' is applied in reference to the simultaneous upward movement of both eyes, although the reaction may encompass a variety of additional responses. The reaction is not life-threatening. For clarification, oculogyric seizures, also termed versive seizures, represent one of the manifestations of epilepsy. These seizures exhibit the same upward eye movement observed in OGC but are classified as a specific subtype of epilepsy. Signs and symptoms Initial symptoms include restlessness, agitation, malaise, or a fixed stare. Then comes the more characteristically described extreme and sustained upward deviation of the eyes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paroxysmal
Paroxysmal attacks or paroxysms are a sudden recurrence or intensification of symptoms, such as a spasm or seizure. These short, frequent symptoms can be observed in various clinical conditions. They are usually associated with multiple sclerosis or pertussis, but they may also be observed in other disorders such as encephalitis, head trauma, stroke, autism, asthma, trigeminal neuralgia, breath-holding spells, epilepsy, malaria, tabes dorsalis, Behçet's disease, and paroxysmal nocturnal hemoglobinuria (PNH). It has also been noted as a symptom of gratification disorder in children. The word '' paroxysm'' means 'sudden attack, outburst' and comes .

Cetirizine
Cetirizine is a second-generation antihistamine, second-generation Peripherally selective antihistamine used to treat allergic rhinitis (hay fever), dermatitis, and urticaria (hives). It is taken by mouth. Effects generally begin within thirty minutes and last for about a day. The degree of benefit is similar to other antihistamines such as diphenhydramine, which is a first-generation antihistamine. Common side effects include sleepiness, dry mouth, headache, and abdominal pain. The degree of sleepiness that occurs is generally less than with first-generation antihistamines because second-generation antihistamines are more selective for the Histamine H1 receptor, H1 receptor. Compared to other second-generation antihistamines, cetirizine can cause drowsiness. Among second-generation antihistamines, cetirizine is more likely than fexofenadine and loratadine to cause drowsiness. Use in pregnancy appears safe, but use during breastfeeding is not recommended.

Reserpine
Reserpine is a drug that is used for the treatment of hypertension, high blood pressure, usually in combination with a thiazide diuretic or vasodilator. Large clinical trials have shown that combined treatment with reserpine plus a thiazide diuretic reduces mortality of people with hypertension. Although the use of reserpine as a solo drug has declined since it was first approved by the FDA in 1955, the combined use of reserpine and a thiazide diuretic or vasodilator is still recommended in patients who do not achieve adequate lowering of blood pressure with first-line drug treatment alone. The reserpine-hydrochlorothiazide combo pill was the 17th most commonly prescribed of the 43 combination antihypertensive pills available in 2012. The antihypertensive actions of reserpine are largely due to its antinoradrenergic effects, which are a result of its ability to deplete catecholamines (among other monoamine neurotransmitters) from peripheral nervous system, peripheral sympathetic ...

Phencyclidine
Phencyclidine or phenylcyclohexyl piperidine (PCP), also known in its use as a street drug as angel dust among other names, is a dissociative anesthetic mainly used recreationally for its significant mind-altering effects. PCP may cause hallucinations, distorted perceptions of sounds, and psychotic behavior. As a recreational drug, it is typically smoked, but may be taken by mouth, snorted, or injected. It may also be mixed with cannabis or tobacco. Adverse effects may include paranoia, addiction, and an increased risk of suicide, as well as seizures and coma in cases of overdose. Flashbacks may occur despite stopping usage. Chemically, PCP is a member of the arylcyclohexylamine class. PCP works primarily as an NMDA receptor antagonist. PCP is most commonly used in the US. While usage peaked in the US in the 1970s, between 2005 and 2011, an increase in visits to emergency departments as a result of the drug occurred. As of 2022, in the US, about 0.7% of 12th-grade ...

Pemoline
Pemoline, formerly sold under the brand name Cylert among others, is a stimulant medication which was used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy,- it has since been discontinued in most countries due to rare but serious liver toxicity. The medication was taken by mouth. Common side effects include insomnia, decreased appetite, abdominal pain, irritability, and headaches, while rare cases of serious liver damage requiring liver transplantation or causing death have been reported. As a stimulant, Pemoline acts as a selective dopamine reuptake inhibitor and releasing agent via indirect agonism of dopamine receptors. In addition, it shows little activity with respect to norepinephrine, thus minimal to no cardiovascular or sympathomimetic effects in comparison to many other stimulants. Pemoline was first synthesized in 1913, but its stimulant activity was not discovered until the 1930s, nor used for ADHD until 1975. Between ...

Domperidone
Domperidone, sold under the brand name Motilium among others, is a dopamine antagonist medication which is used to treat nausea and vomiting and certain gastrointestinal problems like gastroparesis (delayed gastric emptying). It raises the level of prolactin in the human body and is used off label to induce and promote breast milk production. It may be taken by mouth or rectally. Side effects may include headache, anxiety, dry mouth, abdominal cramps, diarrhea, and elevated prolactin levels. Secondary to increased prolactin levels, breast changes, milk outflow, menstrual irregularities, and hypogonadism can occur. Domperidone may also cause QT prolongation and has rarely been associated with serious cardiac complications such as sudden cardiac death. However, the risks are small and occur more with high doses. Domperidone acts as a peripherally selective antagonist of the dopamine D2 and D3 receptors. Due to its low entry into the brain, the side effects of ...

Lurasidone
Lurasidone, sold under the brand name Latuda among others, is an atypical antipsychotic medication used to treat schizophrenia and bipolar depression. It is taken by mouth. Common side effects include sedation, indigestion, nausea, and insomnia. At higher dosages, there is an increased risk for restlessness and movement problems. Serious side effects are valid for all atypical antipsychotics and may include the potentially permanent movement disorder tardive dyskinesia, as well as neuroleptic malignant syndrome, an increased risk of suicide, angioedema, and high blood sugar levels. Although lurasidone is less likely to cause high blood sugar levels in most patients, hyperosmolar hyperglycemic syndrome may occur. In older people with psychosis as a result of dementia, it may increase the risk of dying. Use during pregnancy is of unclear safety. Lurasidone was first approved for medical use in the United States in 2010. In 2013, it was approved in Canada and by the U.S. Fo ...
