However, due to increased levels of drowsiness caused by the medication, it is generally of limited use in pilots and aircrew who must be dependably alert. [ 6 ] Additionally, cinnarizine can be used in scuba divers without an increased risk of central nervous system oxygen toxicity which can result in seizures, and is a high risk in closed ...
Some common side effects such as drowsiness, dry mouth, and tiredness may occur. Meclizine has been shown to have fewer dry mouth side effects than the traditional treatment for motion sickness, transdermal scopolamine. [16] A very serious allergic reaction to this drug is unlikely, but immediate medical attention should be sought if it occurs.
Cyclizine was quickly clinically found as a potent and long-acting antiemetic. The company named the substance – or more precisely cyclizine's hydrochloride form which it usually appears in – "marezine hydrochloride" and started to sell it in the United States under trade name Marezine. Selling was begun in France under trade name Marzine ...
Diphenhydramine reduces nausea but causes drowsiness, and the stimulant properties of 8-Chlorotheophylline help reduce that side effect. [ 2 ] Despite being classified as a xanthine stimulant, 8-chlorotheophylline can generally not produce any locomotor activity above control in mice and does not appear to cross the blood-brain barrier well.
An antiemetic is a drug that is effective against vomiting and nausea. Antiemetics are typically used to treat motion sickness and the side effects of opioid analgesics, general anaesthetics, and chemotherapy directed against cancer. They may be used for severe cases of gastroenteritis, especially if the patient is dehydrated. [1] [2]
Thiethylperazine (Torecan, Norzine) is an antiemetic [1] of the phenothiazine class. It is an antagonist of dopamine receptors (DRD1, DRD2, DRD4) as well as of 5-HT 2A, 5-HT 2C receptors, mAChRs (1 through 5), α 1 adrenergic receptor and H 1 receptor. Thiethylperazine activates the transport protein ABCC1 that clears beta-amyloid from brains ...
Prochlorperazine can also cause a life-threatening condition called neuroleptic malignant syndrome (NMS). Some symptoms of NMS include high fever, stiff muscles, neck muscle spasms, confusion, irregular pulse or blood pressure, fast heart rate (tachycardia), sweating, and abnormal heart rhythms (arrhythmias).
Chlorpromazine, an antipsychotic and antiemetic drug which is classed as a "major" tranquilizer, may cause paradoxical effects such as agitation, hallucinations, excitement, insomnia, bizarre dreams, aggravation of psychotic symptoms and toxic confusional states. [8] These may be more common in elderly dementia patients.
