H3 YKey: DUGOZIWVEXMGBE- UHFFFAOYSA- N Y (verify)Methylphenidate, sold under various trade names, Ritalin being one of the most commonly known, is a central nervous system (CNS) stimulant of the phenethylamine and piperidineclasses that is used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. The original patent was owned by CIBA, now Novartis Corporation. It was first licensed by the US Food and Drug Administration (FDA) in 1. Medical use began in 1.
ADHD became more widely accepted. Between 2. United Kingdom and in 2. The United States continues to account for more than 8. ADHD and other similar conditions are believed to be linked to sub- performance of the dopamine and norepinephrine functions in the brain, primarily in the prefrontal cortex, responsible for executive function (e. Methylphenidate's mechanism of action involves the inhibition of catecholaminereuptake, primarily as a dopamine reuptake inhibitor. Methylphenidate acts by blocking the dopamine transporter and norepinephrine transporter, leading to increased concentrations of dopamine and norepinephrine within the synaptic cleft.
This effect in turn leads to increased neurotransmission of dopamine and norepinephrine.[1. John Deere Party Ideas For Adults on this page. Methylphenidate is also a weak 5. HT1. Areceptoragonist.[1.
MedicalMethylphenidate is a commonly prescribed psychostimulant and works by increasing the activity of the central nervous system.[1. It produces such effects as increasing or maintaining alertness, combating fatigue, and improving attention.[1. The short- term benefits and cost effectiveness of methylphenidate are well established.[1. Methylphenidate is not approved for children under six years of age.[1. Methylphenidate may also be prescribed for off- label use in treatment- resistant cases of bipolar disorder and major depressive disorder.[1. Meta- analyses and systematic reviews of magnetic resonance imaging (MRI) studies suggest that long- term treatment with ADHD stimulants (specifically, amphetamine and methylphenidate) decreases abnormalities in brain structure and function found in subjects with ADHD.[1.
Moreover, reviews of clinical stimulant research have established the safety and effectiveness of the long- term use of ADHD stimulants for individuals with ADHD.[2. In particular, the continuous treatment effectiveness and safety of both amphetamine and methylphenidate have been demonstrated in controlled drug trials with durations of several years; [2.
ADHD symptoms and quality of life that are produced by methylphenidate treatment remains uncertain as of November 2. Attention deficit hyperactivity disorderMethylphenidate is approved by the US Food and Drug Administration (FDA) for the treatment of attention deficit hyperactivity disorder.[2. The addition of behavioural modification therapy (e.
CBT)) can have additional benefits on treatment outcome.[2. The dosage used can vary quite significantly among individuals; consequently, dosage must be titrated precisely.[2. Current models of ADHD suggest that it is associated with functional impairments in some of the brain's neurotransmitter systems,[note 1] particularly those involving dopamine and norepinephrine.[3. Psychostimulants like methylphenidate and amphetamine may be effective in treating ADHD because they increase neurotransmitter activity in these systems.[3. Approximately 7. 0% of those who use these stimulants see improvements in ADHD symptoms.[3. Children with ADHD who use stimulant medications generally have better relationships with peers and family members,[2.
People with ADHD have an increased risk of substance use disorders, and stimulant medications reduce this risk.[3. Some studies suggest that since ADHD diagnosis is increasing significantly around the world, using the drug may cause more harm than good in some populations with ADHD.[3.
This applies to people who potentially may be experiencing a different issue and are misdiagnosed with ADHD.[3.
Side Effects and Drug Images at Rx. List. What should I discuss with my healthcare provider before taking methylphenidate? Do not take methylphenidate if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) within the past 1. Serious, life- threatening side effects can occur if you use methylphenidate before the MAO inhibitor has cleared from your body. Do not use this medication if you are allergic to methylphenidate or if you have: glaucoma; overactive thyroid; severe high blood pressure; angina (chest pain), heart failure, heart rhythm disorder, or recent heart attack; a personal or family history of tics (muscle twitches) or Tourette's syndrome; severe anxiety, tension, or agitation (methylphenidate can make these symptoms worse); ora hereditary condition such as fructose intolerance, glucose- galactose malabsorption, or sucrase- isomaltase insufficiency. Some stimulants have caused sudden death in children and adolescents with serious heart problems or congenital heart defects. Tell your doctor if you have a congenital heart defect.
If you have any of these other conditions, you may need a dose adjustment or special tests: a congenital heart defect; a personal or family history of mental illness, psychotic disorder, bipolar illness, depression, or suicide attempt; epilepsy or other seizure disorder; ora history of drug or alcohol addiction. FDA pregnancy category C. It is not known whether methylphenidate will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication. It is not known whether methylphenidate passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast- feeding a baby. Long- term use of methylphenidate can slow a child's growth.
Tell your doctor if the child using this medication is not growing or gaining weight properly. Do not give methylphenidate to a child younger than 6 years old without the advice of a doctor. How should I take methylphenidate? Take exactly as prescribed by your doctor.
Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Take this medication at least 3. The extended- release forms of methylphenidate (Ritalin- SR, Metadate ER, Metadate CD, Methylin ER, Concerta) can be taken with or without food. The chewable tablet must be chewed before you swallow it. Do not crush, chew, or break an extended- release tablet. Swallow it whole.
Breaking the pill may cause too much of the drug to be released at one time. You may open the extended- release capsule and sprinkle the medicine into a spoonful of pudding or applesauce to make swallowing easier. Swallow right away without chewing. Do not save the mixture for later use. Discard the empty capsule. Measure liquid medicine with a special dose- measuring spoon or cup, not a regular table spoon. If you do not have a dose- measuring device, ask your pharmacist for one.
To prevent sleep problems, take this medication early in the day, no later than 6: 0. If you need to have any type of surgery, tell the surgeon ahead of time that you are using methylphenidate. You may need to stop using the medicine the day of your surgery. Store at room temperature away from moisture and heat. Keep track of the amount of medicine used from each new bottle. Methylphenidate is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Ritalin Helps.. but what about the side effects? Dealing with Stimulant Side effects.
The stimulants are often used to treat AD/HD and other conditions. The most common stimulants are methylphenidate (Ritalin, Concerta, Metadate- ER, and the Daytrana patch) and amphetamine (Dexedrine, Dexedrine Spansules, Adderall and Adderall XR and Vyvanse.) We have been using these medications for years.
Despite some dramatic media reports, the stimulants have a fairly good safety record. When a medication gives you a symptom that you did not want, we call that symptom a side effect. Many individuals take stimulants with few side effects. Others experience mild problems.
Some are simply unable to tolerate stimulants. Often we can treat annoying side effects so the individual can continue to take the stimulant. Too many people stop their medication instead of working with their physician to find a way to decrease side effects.
On the other hand, stimulants can have the potential for real side effects. This is why it is a good idea to keep in close contact with your doctor, especially during the early stages of treatment. Often we can treat side effects so you can continue to take your medication. Instead of stopping your medication, work with your physician to find a way to reduce side effects. Reduced appetite: This effect may be worse in the very young. It may improve after several weeks or months. If it continues to be problematic, one may reduce the dose; or time a short- acting stimulant to wear off before mealtimes.
On the average, the methylphenidate compounds have slightly less of an appetite effect than the amphetamines. However this can vary from one individual to another. In some cases we resign ourselves to a eating a large breakfast and supper followed by a very small lunch. A large late evening snack can also help. I see less appetite suppression in adults. I suspect that this is because that adults may eat for different reasons than children. An adult is more likely to eat for psychological or social reasons. Many adults hope that they will shed some extra pounds while taking stimulants.
Sometimes they do but other times they do not. Non- stimulant AD/HD medications may not cause as much appetite suppression. Rebound: Some people who take short acting methylphenidate or amphetamine experience irritability or depression for an hour as the stimulant wears off. Sometimes this is worse than the individual’s behavior before the medication was started. One can avoid rebound by spacing the doses closer together, giving a smaller dose after the final larger dose, or by switching to a longer acting stimulant. Recently several new long- acting stimulant preparations have been released. Although the long- acting compounds often have less rebound, the problem may still occur in susceptible individuals.
Sometimes, we add a small dose of short- acting stimulant when the longer- acting stimulant wears off. This can have tradeoffs. If the stimulant reduces appetite, the extra dose of short acting stimulant may create problems with the evening meal. Headache: If this does not improve with time, we may reduce the dose or switch to another stimulant. Sometimes caffeine restriction helps.
If one is a heavy consumer of caffeine, one should taper rather than stop the caffeine. If one stops the caffeine suddenly, the result is often a caffeine withdrawal headache. If sudden caffeine cessation happens at the same time as the start of the stimulant, the caffeine withdrawal headache may be mistaken for a stimulant side effect. Many individuals with untreated AD/HD may try to self medicate with caffeine and thus have a substantial caffeine dependence. Jittery feeling: Eliminate caffeine or other stimulant- type medications.
A small dose of a beta- blocker (a type of blood pressure medication) can block tremor or jitters. Make sure that the individual is eating regular meals. Some people are especially susceptible to this side effect and simply cannot tolerate stimulants. In this case we may need to prescribe a nonstimulant AD/HD medication. Gastrointestinal upset: Take the medication with meals or eat smaller, more frequent meals.
Sleep difficulty: It is a good idea to take a sleep history before starting a stimulant medication. Sometimes the sleep problem is due to the AD/HD, not the medication. One the average, people with AD/HD have more sleep problems than individuals without AD/HD. This is separate from any medication effect. If the sleep problem is truly due to medication effect, we have several options. Sleep difficulty is more common when one is using a long- acting stimulant or if one is giving a short- acting stimulant late in the evening. Now that there are more long- acting stimulants on the market, one can often eliminate this problem by using one of the more intermediate- length stimulants.
Clonidine or guanfacine may help decrease agitation and may also facilitate sleep. We also counsel the individual on establishing good sleep habits.
