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. Antiemetics, though previously thought to cause birth defects, have been proven safe for use by pregnant women in the treatment of morning sickness and the more serious hyperemesis gravidarum. Bismuth subsalicylate works by protecting the stomach lining. Antihistamines appear to dull the inner ear’s ability to sense motion. They “block” messages to the part of the brain that controls nausea and vomiting. This is why they work best if you take them before you think you might have a problem with motion sickness.
Anticonvulsant Medication for Bipolar Disorder : Several anticonvulsant medications are recognized as mood stabilizers to treat or prevent mood episodes in bipolar disorder. At first, anticonvulsants were prescribed only for people who did not respond to lithium. Today, they are often prescribed alone, with lithium, or with an antipsychotic drug to control mania. Anticonvulsants work by calming hyperactivity in the brain in various ways. For this reason, some of these drugs are used to treat epilepsy,prevent migraines, and treat other brain disorders. They are often prescribed for people who have rapid cycling — four or more episodes of mania and depression in a year. Anticonvulsants used to treat bipolar disorder include: Depakote, Depakene (divalproex sodium, valproic acid, or valproate sodium) Lamictal (lamotrigine) Tegretol (carbamazepine)
Anticoagulants are medicines that reduce blood clotting in an artery, vein or the heart. Clots can block the blood flow to your heart muscles and cause a heart attack. They can also block blood flow to your brain, causing a stroke. They can keep harmful clots from forming in your heart, veins or arteries. Blood clots are made up of red blood cells, platelets, fibrin, and white blood cells. Anticoagulants prevent these components from sticking together and forming a clot. Anticoagulant drugs fall into three groups: 1) Inhibitors of clotting factor synthesis: Warfarin 2) Inhibitors of Thrombin: Argatroban, Bivalirudin and Lepirudin, Refludan 3) Antiplatelet drugs: Aspirin, Clopidogrel, Ticlopidine, Tirofiban.
