Dextroamphetamine bioavailability

Common Questions and Answers about Dextroamphetamine bioavailability

Avatar n tn Atorvastatin is supposed to be one of the two most effective statins in lowing cholesterol so you are on a good one. Bioavailability is how well a med is absorbed and used by the body and bioavailability varies among the statins. It's actually a desired thing. The liver is the target organ so if it is slowed down in the liver (where this happens), it's in the target organ. But honestly, that is hard for me to understand.
Avatar f tn Certain drugs could be responsible like metoclopramide, prednisone, effexor, an antidepressant, paxil, an SSRI, wellbutrin, an antidepressant, Zoloft an SSRI and dextroamphetamine, a CNS stimulant. Consult a neurologist soon who will evaluate you for these symptoms and investigate these appropriately. Take care.
Avatar m tn Although a standard meal did not affect ribavirin bioavailability (F1), administration of ribavirin with a high-fat meal increased bioavailability by 46% relative to the fasting state. A high-fat meal prolonged the duration of the zero-order input part of the absorption model, with D1 increasing from 0.498 h (fasting and standard meal) to 0.740 h. The type of meal also influenced the first-order input part of the absorption model (Table 1).

Avatar m tn * Stimulant medications, such as dextroamphetamine-based drugs (Adderall, Vyvanese) and methylphenidate-based drugs (Concerta, Daytrana, Ritalin). They are also available as generics. * Nonstimulant medication, such as the antidepressant bupropion (Wellbutrin and generic) or atomoxetine (Strattera), which is not available as a generic.
Avatar f tn When a medication is administered intravenously, its bioavailability is 100%. However, when a medication is administered orally, its bioavailability decreases because not all of it is absorbed. So 70% bioavailability means that, from the dose you took, 70% of it reached systemic circulation. "Two studies have been carried out to assess the effect of food (ie, a high-fat breakfast) on the bioavailability of a SINGLE oral dose of ribavirin. An initial study by ICN Pharmaceuticals, Inc.
Avatar f tn Also as a side note, Opana oral bioavailability is actually very low. Lower than morphine I believe the bioavailability is around 10 percent. However, if you reach your optimal dose, bioavailability matters little. I see that this post is from October 2011. But since I have this typed, I'll post anyway :) Good luck and gentle hugs.
Avatar f tn your son has apparently experienced positive results with Concerta which is a form of methylphenidate, while Adderall is a form of dextroamphetamine (Ritalin and Dexedrine). Frequently the forms of methylphenidate work better for ADHD Hyperactive while the dextroamphetamines work better for the Inattentive. Which is your son? To compound matters further if he is an "active" young man, is his activity "motor" or "distractablitIy" driven?
Avatar m tn t expensive at all and is called mixed amphetamine salts or amphetamine, dextroamphetamine mixed salts. Something like less than a dollar per pill.
1654177 tn?1319838494 Also best not to take drugs with lots of fiber as they can bind to the fiber and pass through the system before total absorption thus decreasing bioavailability. You need all the bioavailability you can get!.
Avatar f tn Blood tests are not accurate for testing the active bioavailability of sex hormones in the cells and tissues. They only test what's in the blood stream. They aren't accurate for testing when a patient is using bioidentical topical creams. I've had two holistic doctors tell me this and have read numerous articles about which testing is correct depending on which type of hormones you're taking.
Avatar n tn The ascorbate in Ferrous Ascorbate helps retardation or prevention of Fe(II) oxidation by ascorbate and to the existence of Fe(II) as a chelate with ascorbate ( vitamin C if you like ). Ferrous Ascrorbate will have a better bioavailability but you can add a vitamin C and vitamins B complex with sodium feredetate and have pretty good results. Depending on your needs; are you lacking iron? anemia?

1165577 tn?1263001618 You are right about the drugs being in the same family, they are all psychostimulants mainly composed of amphetamine and/or dextroamphetamine, levoamphetamine,and other stuff like that... SugieSprinks, the medication change won't affect your weight simply because amphetamine kind of drugs decrease appetite regardless of the brand.I think the reason your doctor switched you to Vyvanse is because of the reduced side effects and drug lasting longer.
Avatar f tn The combination of drugs, citalopram that is a selective serotonin reuptake inhibitor and amphetamine and dextroamphetamine that are dopamine and norepinephrine reuptake inhibitor is not recommended. Amphetamines may possess serotonergic activity and should not be administered with SSRIs as there is an additive risk of serotonin syndrome. Enhanced sympathomimetic effects is possible.
Avatar n tn ve never been diagnosed with ADD or ADHD but about 2 nights ago, my roommate offered me 4 dextroamphetamine pills to help me study for all of my midterms. I took them all, and my heart was beating really fast and my chest felt tight. Those symptoms went away but now I'm noticing that my arms and head feel slightly shaky. Also, I feel like I'm worse at reading and typing. Is it possible to get permanent side effects from one time abuse of adderall?

Avatar f tn Hi, Adderall, a combination of amphetamine and dextroamphetamine, can stimulate the central nervous system and affect chemicals in the brain and nerves that contribute to hyperactivity and impulse control. This is usually indicated for narcolepsy, attention deficit hyperactivity disorder and may be used for migraine prevention. Hope this helps. Take care and regards.
Dinosaur Thank you for your question, Yes, it is recommended you take it in the morning on an empty stomach, at least 30 minutes before food. Taking levothyroxine with food may cause reduced bioavailability and may lower drug levels leading to signs or symptoms of hypothyroidism. In addition, cottonseed meal, walnuts, and dietary fiber may decrease absorption of levothyroxine from the GI tract.
Avatar m tn Often I’ve had twitching in various parts of my body, even my eyelid, and after taking a magnesium supplement (Magnesium citrate is one of the best and has very good bioavailability; Magnesium Oxide is not recommended because of its very poor bioavailability!), my twitches stopped within a day! It’s easy to find on Amazon. I only mention these things because it is common to have low Vitamin D as well as low Magnesium. I hope your husband is feeling better soon.

Avatar m tn You don't say why you are taking Clonidine? Because of your age, I'm going to guess that it's for attention-deficit disorder. One of the side effects of Clonidine can be a sense of shortness of breath. Vyvanse, another med for ADHD, can also cause shortness of breath. There is no medication with the name 'dextromaphane,' but there is Dextroamphetamine. Is this what you are taking? It also is used to treat ADHD.
