What is An1?
An1 is used to treat narcolepsy (sleep disorder). It is also used to treat attention-deficit hyperactivity disorder (ADHD). It belongs to the group of medicines called central nervous system (CNS) stimulants.
An1 is also used for weight reduction in obese patients.
An1 works in the treatment of ADHD by increasing attention and decreasing restlessness in children and adults who are overactive, cannot concentrate for very long, or are easily distracted and impulsive. An1 is used as part of a total treatment program that also includes social, educational, and psychological treatment.
An1 is available only with a doctor's prescription.
An1 is indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in pediatric patients 6 to 17 years of age.
How should I use An1?
Use An1 as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- An1 comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get An1 refilled.
- Take An1 by mouth with or without food.
- Take your doses of An1 4 to 6 hours apart unless your doctor tells you otherwise.
- Do not drink fruit juice at the same time that you take An1. Certain fruit juices (eg, grapefruit, apple, orange) may decrease An1's effectiveness.
- Take An1 on a regular schedule to get the most benefit from it. Taking An1 at the same time each day will help you remember to take it.
- If you miss a dose of An1, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use An1.
Amphetamines are non-catecholamine sympathomimetic amines with CNS stimulant activity. By mimicking the structures of the catecholamine neurotransmitters, noradrenaline and dopamine, amphetamines modulate monoamine release, reuptake, and signalling within the brain. Although "An1" is used as a descriptor of its own structural class, An1 properly refers to a racemic free base composed of equal parts of its two optical antipodes: levo-An1 and dextro-An1. Used in the past for the treatment of depression, stress, and for concentration improvement, it is currently available as a prescription drug for the treatment of attention hyperactivity disorder (ADHD), narcolepsy, and as an adjunct in the treatment of exogenous obesity. An1 is also available in a mixed salt/mixed enantiomer form (Adderall), where d-An1 and l-An1 are available in a ratio of 3:1. It is also available in a prodrug form as lisdexamfetamine.
Prior to treating patients with An1, assess for the presence of cardiac disease (i.e., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam).
Assess the risk of abuse prior to prescribing and monitor for signs of abuse and dependence while on therapy. Maintain careful prescription records, educate patients about abuse, monitor for signs of abuse and overdose, and periodically re-evaluate the need for An1 use.
Administer An1 orally in the morning with or without food or liquid.
The recommended starting dose of An1 for patients 6 to 17 years of age is 5 mg once or twice daily. If necessary, administer an additional dose after 4 to 6 hours. Titrate the dosage in increments of 5 mg at weekly intervals until optimal response is obtained. Only in rare cases will it be necessary to exceed a total of 40 mg daily.
Where possible, drug administration should be interrupted occasionally to determine if there is a recurrence of behavioral symptoms sufficient to require continued therapy.
An1 should be administered at the lowest effective dosage and dosage should be individually adjusted.
Instruct the patient or caregiver on the following administration instructions:
- Do not remove the tablet from the blister pack until just prior to dosing. Do not store the tablet for future use.
- Use dry hands to open the blister.
- Remove the tablet by pushing it through the back of the foil-lined blister pack.
- As soon as the blister is opened, remove the tablet and place the tablet on the patient's tongue.
- Place the whole tablet on the tongue and allow it to disintegrate without chewing or crushing.
- The tablet will disintegrate in saliva so that it can be swallowed. No liquid is needed to take the tablet. The tablet can be actively moved around between the tongue and the roof of the mouth until it disintegrates.
Switching from Other An1 Products
Switching from EVEKEO to An1 can be done on a milligram-per-milligram basis.
When switching from other An1 products, discontinue treatment and titrate with An1 using the titration schedule above. Do not substitute for other An1 products on a milligram-per-milligram basis because of different An1 salt compositions and differing pharmacokinetic profiles.
Dosage Modifications due to Drug Interactions
Agents that alter urinary pH can impact urinary excretion and alter blood levels of An1. Acidifying agents (e.g., ascorbic acid) decrease blood levels, while alkalinizing agents (e.g., sodium bicarbonate) increase blood levels. Adjust An1 dosage accordingly.
What other drugs will affect An1?
Acidifying agents - Gastrointestinal acidifying agents (guanethidine,reserpine, glutamic acid HCl,ascorbic acid, fruit juices, etc.) lower absorption of amphetamines Urinary acidifying agents -(ammonium chloride, sodium acid phosphate, etc.) Increase the concentration of the ionized species of the An1 Primary excretion - Both Groups of agents lower blood levels and efficacy of amphetamines Adrenergic blockers - Adrenergic blockers are inhibited by amphetamines Alkalinizing agents -Gastrointestinal alkalinizing agents (sodium bicarbonate, etc.)increase absorption of amphetamines. Urinary alkalinizing agents (acetazolamide, some thiazides) increase the concentration of the non-ionized species of the An1 molecule, thereby decreasing urinary excretion. Both groups of agents increase blood levels and therefore potentate the actions of amphetamines Antidepressants, tricyclic - Adipans may enhance the activity of tricyclic or sympathomimetic agents; d-An1 with desipramine or protriptyline and possibly other tricyclics cause striking and sustained increases in the concentration of d-An1 in the brain; cardiovascular effects can be potentiated MAO inhibitors - MAO antidepressants, as well as a metabolite of furazolidone, slow An1 metabolism. This slowing potentiates amphetamines, increasing their effect on the release of norepinephrine and other monoamines from adrenergic nerve endings, this can cause headaches and other signs of hypertensive crisis. A variety of neurological toxic effects and malignant hyperpyrexia can occur, sometimes with fatal results Antihistamines - Adipans may counteract the sedative effect of antihistamines Antihypertensives - Adipans may antagonize the hypotensive effects of antihypertensives Chlorpromazine - Chlorpromazine blocks dopamine and norepinephrine receptors, thus inhibiting the central stimulant effects of amphetamines, and can be used to treat An1 poisoning Ethosuximide - Adipans may delay intestinal absorption of ethosuximide Haloperidol - Haloperidol blocks dopamine receptors, thus inhibiting the central stimulant effects of amphetamines Lithium carbonate - The anorectic and stimulatory effects of amphetamines may be inhibited by lithium carbonate Meperidine - Adipans pone the analgesic effect of meperidine Methenamine therapy - Urinary excretion of amphetamines is increased, and efficacy is reduced, by acidifying agents used in methenamine therapy Norepinephrine - Adipans enhance the adrenergic effect of norepinephrine Phenobarbital - Adipans may delay intestinal absorption of phenobarbital; co-administration of phenobarbital may produce a synergistic anticonvulsant action Phenytoin - Adipans may delay intestinal absorption of phenytoin; co-administration of phenytoin may produce a synergistic anticonvulsant action Propoxyphene - In cases of propoxyphene overdose, An1 CNS stimulation is potentiated and fatal convulsions can occur Veratrum alkaloids - Adipans inhibit the hypotensive effect of veratrum alkaloids Drug/Laboratory Test Interaction Adipans can cause a significant elevation in plasma corticosteroid levels. This increase is greatest in the evening Adipans may interfere with urinary steroid determinations.
