What is Obesin?

Obesin 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.

Obesin is also used for weight reduction in obese patients.

Obesin 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. Obesin is used as part of a total treatment program that also includes social, educational, and psychological treatment.

Obesin is available only with a doctor's prescription.

Obesin indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Obesin description

sponsored

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 "Obesin" is used as a descriptor of its own structural class, Obesin properly refers to a racemic free base composed of equal parts of its two optical antipodes: levo-Obesin and dextro-Obesin. 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. Obesin is also available in a mixed salt/mixed enantiomer form (Adderall), where d-Obesin and l-Obesin are available in a ratio of 3:1. It is also available in a prodrug form as lisdexamfetamine.

Obesin dosage

Obesin Dosage

Generic name: Obesin 2.5mg in 1mL

Dosage form: suspension, extended release

The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.

2.1 Important Information Prior to Initiating Treatment

Prior to treating children, adolescents, and adults with CNS stimulants, including Obesin, 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 Obesin use.

2.2 General Dosing Information

Obesin should be orally administered once daily in the morning with or without food. The dose should be individualized according to the needs and responses of the patient. Before administering the dose, shake the bottle of Obesin.

In children 6 years of age and older, start with 2.5 mg or 5 mg once daily in the morning. The dose may be increased in increments of 2.5 mg to 10 mg per day every 4 to 7 days up to a maximum dose of 20 mg per day.

Pharmacological treatment of ADHD may be needed for extended periods. Healthcare providers should periodically re-evaluate the long-term use of Obesin, and adjust dosage as needed.

2.3 Switching from other Obesin Products

If switching from other Obesin products, discontinue that treatment, and titrate with Obesin using the above titration schedule.

Do not substitute for other Obesin products on a milligram-per-milligram basis, because of different Obesin base compositions and differing pharmacokinetic profiles.

2.4 Dosage Modifications due to Drug Interactions

Agents that alter urinary pH can impact urinary excretion and alter blood levels of Obesin. Acidifying agents (e.g., ascorbic acid) decrease blood levels, while alkalinizing agents (e.g., sodium bicarbonate) increase blood levels. Adjust Obesin dosage accordingly.

Drugs Having Clinically Important Interactions With Amphetamines

Table 5: Drugs having clinically important interactions with amphetamines.

MAO Inhibitors (MAOI)
Clinical Impact MAOI antidepressants slow Obesin metabolism, increasing amphetamines effect on the release of norepinephrine and other monoamines from adrenergic nerve endings causing headaches and other signs of hypertensive crisis. Toxic neurological effects and malignant hyperpyrexia can occur, sometimes with fatal results.
Intervention Do not administer Obesin during or within 14 days following the administration of MAOI.
Examples selegiline, isocarboxazid, phenelzine, tranylcypromine
Alkalinizing Agents
Clinical Impact Increase blood levels and potentiate the action of Obesin.
Intervention Co-administration of Obesin and gastrointestinal alkalinizing agents should be avoided.
Examples Gastrointestinal alkalinizing agents (e.g., sodium bicarbonate).

Urinary alkalinizing agents (e.g., acetazolamide, some thiazides).

Acidifying Agents
Clinical Impact Lower blood levels and efficacy of amphetamines.
Intervention Increase dose based on clinical response.
Examples Gastrointestinal acidifying agents (e.g., guanethidine, reserpine, glutamic acid HCl, ascorbic acid).
Tricyclic Antidepressants
Clinical Impact May enhance the activity of tricyclic or sympathomimetic agents causing striking and sustained increases in the concentration of d-Obesin in the brain; cardiovascular effects can be potentiated.
Intervention Monitor frequently and adjust or use alternative therapy based on clinical response.
Examples desipramine, protriptyline
Proton Pump Inhibitors
Clinical Impact Time to maximum concentration (Tmax) of Obesin is increased compared to when administered alone.
Intervention Monitor patients for changes in clinical effect and adjust therapy based on clinical response.
Example omeprazole

Drug/Laboratory Test Interactions

Amphetamines can cause a significant elevation in plasma corticosteroid levels. This increase is greatest in the evening. Amphetamines may interfere with urinary steroid determinations.

Drug Abuse And Dependence

Controlled Substance

Obesin contains Amphetamine, which is a Schedule II controlled substance in the U.S. Controlled Substance Act (CSA).

Abuse

Obesin, is a CNS stimulant that contains Amphetamine which has a high potential for abuse. Abuse is characterized by impaired control of drug use, compulsive use despite harm, and craving.

Signs and symptoms of Obesin abuse may include increased heart rate, respiratory rate, blood pressure, and/or sweating, dilated pupils, hyperactivity, restlessness, insomnia, decreased appetite, loss of coordination, tremors, flushed skin, vomiting, and/or abdominal pain. Anxiety, psychosis, hostility, aggression, suicidal or homicidal ideation have also been observed. Abusers of amphetamines may use other unapproved routes of administration which can result in overdose and death.

To reduce the abuse of Obesin, assess the risk of abuse prior to prescribing. After prescribing, keep careful prescription records, educate patients and their families about abuse and proper storage and disposal of CNS stimulants, monitor for signs of abuse while on therapy, and re-evaluate the need for Obesin use.

Dependence

Tolerance

Tolerance (a state of adaptation in which exposure to a drug results in a reduction of the drug’s desired and/or undesired effects over time) may occur during the chronic therapy of CNS stimulants including Obesin.

Dependence

Physical dependence (which is manifested by a withdrawal syndrome produced by abrupt cessation, rapid dose reduction, or administration of an antagonist) may occur in patients treated with CNS stimulants including Obesin. Withdrawal symptoms after abrupt cessation following prolonged high dosage administration of CNS stimulants include dysphoric mood; fatigue; vivid, unpleasant dreams; insomnia or hypersomnia; increased appetite; and psychomotor retardation or agitation.
