zofran

2062505 tn?1331089288 Ondansetron is a selective 5-HT3 receptor antagonist. While its mechanism of action has not been fully characterized, ondansetron is not a dopamine-receptor antagonist. Serotonin receptors of the 5-HT3 type are present both peripherally on vagal nerve terminals and centrally in the chemoreceptor trigger zone of the area postrema. It is not certain whether ondansetron’s antiemetic action is mediated centrally, peripherally, or in both sites.
374652 tn?1494811435 Ondansetron is used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy and surgery. Ondansetron is in a class of medications called 5-HT3 receptor antagonists. It works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. it is also known as Zofran. ginger helps too.
Avatar m tn I am not physically restricted - I walk 1 mile or more day and do 10 minutes of other light exercises most days. My BP runs under 120/80 most of the time. I understand carvedilol helps prevent stiffening of the heart muscle and can help restore LV function to some degree. How specially, so it do this? What is the biochemical mechanism?
Avatar f tn That is the generic name for zofran.
Avatar f tn Ondansetron is the generic for Zofran. Why would you refuse it? It's safe to take or your Dr wouldn't prescribe it to you. There's other meds out there if you don't want to take it. My Dr gave me Diclegis. It helped take the edge off the nausea.
Avatar m tn The mechanism of action of Campral® (acamprosate calcium) Delayed-Release Tablets in maintenance of alcohol abstinence is not completely understood. Originally, several neurotransmitter systems, including GABA, were investigated for a possible role in Campral's mechanism of action. However, recent evidence suggests Campral's main interaction is with the glutamate system. Chronic alcohol exposure is hypothesized to alter the normal balance between neuronal excitation and inhibition.

Avatar m tn Oyakawa I am in my 3rd year of medical school and I was wondering the mechanism of action of steroid injections in the eyelid causing cataracts. It is not an osmotic agent so why does that occur? thanks so much.

Avatar m tn It is in a class of medications called 5-HT3 receptor antagonists and works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. I just got a bottle of 30 Ondansetron on Medicare for $5. There are also other similar meds you can take so you should find a solution and not have to deal with what you have been. Call your doctor tomorrow and get a script sent to your pharmacy. It should work immediately if you are taking a high enough dosage.
Avatar f tn Plavix has a unique mechanism of action by blocking the amplification of platelet activation by released ADP, and often used with aspirin to prevent the risk of clots for the first year after DES implant. Plavix and aspirin have different mechanism of action to prevent clots. After a year, plavix is usually discontinue as the risk for clots is decreased, and aspirin is continued long term. The risk of a clot is about 3%.
Avatar f tn Ondansetron has been assigned to pregnancy category B by the FDA. Animal studies failed to reveal evidence of fetal damage. There are no controlled data in human pregnancy. Case reports have described two women who have received ondansetron during pregnancy for life-threatening hyperemesis gravidarum. No abnormalities were noted in the offspring of these two women. Ondansetron is only recommended for use during pregnancy when benefit outweighs risk.

1201433 tn?1328997637 Zofran tablets, syrup and injection all contain the active ingredient ondansetron hydrochloride dihydrate, which is a type of medicine called a 5HT3 antagonist. (NB. Ondansetron is also available without a brand name, ie as the generic medicine.) Ondansetron is used to prevent and treat nausea and vomiting that can be caused by chemotherapy or radiotherapy treatment for cancer, or by surgery. Vomiting is controlled by an area of the brain called the vomiting centre.
Avatar f tn Potassium is a chemical element and it is part of the electrolyte that should be in balance with other lytes to adequately conduct an electrical impulse that originates with the sinus node in the right atrium. The mechanism of action is not completely understood, but what is when a voltage (unit of potential for conduction) and electrolyte there will conduction and passage of electrical impluses.

Gastroenterology. 2010 Jul;139 The therapeutic mechanisms of ribavirin for hepatitis C are unclear. Microarray analyses have shown that ribavirin increases induction of interferon-stimulated genes. We evaluated viral kinetics, serum cytokine expression, and viral mutagenesis during early stages of peginterferon therapy with and without ribavirin.

Avatar n tn Some medications are actually derived from plants. The mechanism of action and effect on the body determines the classification, therefore, laxatives can be synthetic or natural.
Avatar n tn "Mechanism of Action Oxomemazine, a phenothiazine derivative, is a sedating antihistamine" The above information is about all I could find on this drug. If it is used in the US, I have no idea what label it's under. Even if I had been able to find more information, I am not qualified to tell you to either stop or start or change any medications. You need to speak with your doctor or chemist for an answer to your question.
Avatar f tn All I know is they do not prescribe it to one indivodual in large quantities and that bc it can affect and stay in your blood for so long they have to monitor how much an individual gets. Like if youve used it the last 6 months, ondansetron is one of two or three prescribed pills that eliminate you as a donor for plasma, blood, or other things.
Avatar f tn , duloxetine) has a combination mechanism of action involving serotonin and norepinephrine making it useful in depression and also neuropathic pain. When a peripheral nerve is injured there is an increase in pain sensitive fibers leading to increase pain recognition. This causes a change in central (i.e., brain/spinal cord) recognition of pain. One major neurotransmitter involved in this is norepinephrine. Cymbalta works to modulate this change.
Avatar n tn A heart murmur is a sound heard as the blood flows through the heart and especially the blood flow through the heart valves. If there is a defect, a stethoscope hears a specific sound for different defects. ■Angiotensin-converting enzyme (ACE) inhibitors. ACE inhibitors lower the system's blood pressure. The mechanism of action is to relax the blood vessels and that provides less resistance for the heart to pump against and decreases blood pressure.
