  • The possibility that family members may abuse the patient’s medication should be considered.5



  • Sudden Death and Serious Cardiovascular Events


  • Possible sudden death and serious cardiovascular events, particularly in individuals who abuse amphetamines.1 6 9 (See Sudden Death and Serious Cardiovascular Events under Cautions.)




Introduction

Prodrug of dextroamphetamine; noncatechol, sympathomimetic amine with CNS-stimulating activity.1 8 28


Uses for Vyvanse


Attention Deficit Hyperactivity Disorder


Used as an adjunct to psychological, educational, social, and other remedial measures in the treatment of attention deficit hyperactivity disorder (ADHD) (hyperkinetic disorder, hyperkinetic syndrome of childhood, minimal brain dysfunction).1 3 6 7 8 28


Safety and efficacy established in children 6–12 years of age who met criteria for ADHD (combined type or predominantly hyperactive-impulsive type) and also in adults who met criteria for ADHD.1 2 3 4 29 30


Almost all studies comparing behavioral therapy versus stimulants alone have shown a much stronger therapeutic effect from stimulants than from behavioral therapy, and stimulants (e.g., amphetamines, methylphenidate) remain the drugs of choice for the management of ADHD.5 6 7 10 11 12 13 14 15 16 17 18 19 20


Drug therapy is not indicated in all patients with ADHD, and such therapy should be considered only after a complete evaluation including medical history has been performed.1 6 17 18


Use should depend on age, adequate diagnosis (based on medical, special psychological, educational, and social resources), and the clinician’s assessment of the severity, duration, and frequency of symptoms and should not depend solely on one or more behavioral characteristics.1 5 6 17


Vyvanse Dosage and Administration


Administration


Oral Administration


Administer once daily in the morning without regard to meals.1 Because of potential for insomnia, avoid administering in the afternoon.1 28 30

Cautions for Vyvanse


Contraindications



  • Contraindicated in patients with advanced arteriosclerosis,1 5 28 symptomatic cardiovascular disease,1 5 28 moderate to severe hypertension,1 5 28 hyperthyroidism,1 5 28 known hypersensitivity or idiosyncrasy to sympathomimetic amines,1 5 glaucoma,1 5 28 or a history of drug abuse;1 5 28 within 14 days of MAO inhibitor therapy;1 5 28 and in agitated patients.1 28




  • Although amphetamines generally should not be used in patients with a history of drug abuse,1 5 some experts state that this is not an absolute contraindication, provided the patient can be monitored more carefully than would otherwise be indicated.5



Warnings/Precautions


Warnings


Sudden Death and Serious Cardiovascular Events

Sudden unexplained death, stroke, and MI reported in adults with ADHD receiving usual dosages of stimulants; sudden death also reported in children and adolescents with structural cardiac abnormalities or other serious cardiac conditions receiving usual dosages of the drugs.1 9


Epidemiologic data suggest a possible association between use of stimulants and sudden unexplained death in healthy children and adolescents.31 32 33 FDA unable to conclude that these data affect evaluation of overall risk and benefit of stimulants used to treat ADHD in children and adolescents.31 FDA is conducting an ongoing safety review of amphetamines and other stimulants to evaluate possible link between use of these agents and sudden death in children.31 32 33 Pediatric patients with ADHD and their parents should avoid discontinuing the child’s use of such stimulants before consulting a clinician.31


Thoroughly review medical history (including evaluation for family history of sudden death or ventricular arrhythmia) and perform physical examination in all children, adolescents, and adults being considered for stimulant therapy; if initial findings suggest presence of cardiac disease, perform further cardiac evaluation (e.g., ECG, echocardiogram).1 5 6


In general, avoid use of CNS stimulants in patients with known serious structural cardiac abnormalities, cardiomyopathy, serious heart rhythm abnormalities, CAD, or other serious cardiac conditions.1 6 8 9 (See Contraindications under Cautions.)


Patients who develop exertional chest pain, unexplained syncope, or other manifestations suggestive of cardiac disease during stimulant therapy should undergo prompt cardiac evaluation.1 28


Other Warnings and Precautions


Least amount of lisdexamfetamine feasible should be prescribed or dispensed at one time in order to minimize possible overdosage.1


Effects on BP and Heart Rate

Possible modest increases in average BP (i.e., by about 2–4 mm Hg) and heart rate (i.e., by about 3–6 bpm); larger increases may occur.1 28 Modest increases not expected to have short-term sequelae; however, monitor all patients for larger changes in BP and heart rate.1


Caution advised in patients with underlying medical conditions that might be affected by increases in BP or heart rate (e.g., hypertension, heart failure, recent MI, ventricular arrhythmia).1


Exacerbation or Precipitation of Psychotic Symptoms

May exacerbate symptoms of behavior disturbance and thought disorder in patients with preexisting psychotic disorder.1 5


Psychotic symptoms (e.g., hallucinations, delusional thinking) may occur with usual dosages in children and adolescents without prior history of psychotic illness.1 6 If psychotic symptoms occur, consider causal relationship to stimulants, and discontinue therapy as appropriate.1 6


Precipitation of Manic Symptoms

May precipitate mixed or manic episodes in ADHD patients with comorbid bipolar disorder; use with caution in these patients.1 Prior to initiating therapy, carefully screen patients with ADHD and comorbid depressive symptoms to identify risk for bipolar disorder; screening should include a detailed psychiatric history (e.g., family history of suicide, bipolar disorder, or depression).1


Manic symptoms may occur with usual dosages in children and adolescents without prior history of mania.1 If manic symptoms occur, consider causal relationship to stimulants, and discontinue therapy as appropriate.1


Aggression

Aggressive behavior and hostility (frequently observed in children and adolescents with ADHD) reported in patients receiving drug therapy for ADHD.1 No systematic evidence that stimulants cause these adverse effects; however, monitor patients beginning treatment for ADHD for onset or worsening of aggressive behavior or hostility.1 6


Growth Suppression

Long-term (i.e., >12 months) administration expected to cause at least a temporary suppression of normal weight and/or height patterns in some children and adolescents.1 6 Dose-related weight loss reported in children during 4 weeks of therapy with lisdexamfetamine.1


Manufacturer recommends monitoring growth during treatment; patients not growing or gaining weight as expected may require temporary discontinuance of treatment.1 6 28 However, AAP states that studies of stimulants in children found little or no decrease in expected height, with any decrease in growth early in treatment being compensated for later on.7


Seizures

Possible lowering of seizure threshold in patients with history of seizures, in those with prior EEG abnormalities but no history of seizures, and, very rarely, in those without history of seizures and with no prior evidence of EEG abnormalities.1 28 If seizures occur, discontinue therapy.1


Visual Effects

Visual disturbances (e.g., difficulty with accommodation, blurred vision) reported with stimulants.1 28


Tics

Amphetamines reported to exacerbate motor and phonic tics and Tourette’s syndrome.1 However, a history of tics or their development during therapy is not an absolute contraindication to continued use.1 5 7 Nevertheless, evaluate for presence of tics and Tourette’s syndrome in children and their families prior to initiating stimulant therapy.1


Other CNS Effects

Amphetamines may impair the ability to engage in potentially hazardous activities (e.g., operating machinery or vehicles).1


Specific Populations


Pregnancy

Category C.1 25


Risk of prematurity, low birth weight, and withdrawal symptoms (e.g., dysphoria, lassitude, agitation) in infants born to dependent women.1 25


Lactation

Distributed into milk; discontinue nursing or the drug.1 25


Pediatric Use

Safety and efficacy of lisdexamfetamine not established in children 3–5 years of age.1 Amphetamines not recommended for ADHD in children <3 years of age.1 5 6 Not studied to date in adolescents.1


Aggressive behavior, hostility, and psychotic (e.g., hallucinations, delusional thinking) or manic symptoms reported in children and adolescents receiving stimulants for management of ADHD.1 (See Warnings under Cautions.)


Sudden death reported in children and adolescents with structural cardiac abnormalities or other serious cardiac conditions receiving usual dosages of stimulants.1 Epidemiologic data also suggest a possible association between use of stimulants and sudden death in healthy children and adolescents.31 32 33 (See Sudden Death and Serious Cardiovascular Events under Cautions.)


Long-term administration expected to cause at least a temporary suppression of normal weight and/or height patterns in some children and adolescents.1 (See Growth Suppression under Cautions.)


Geriatric Use

Lisdexamfetamine has not been studied in this population.1


Hepatic Impairment

Not specifically studied in hepatic impairment.27


Renal Impairment

Not specifically studied in renal impairment.27


Common Adverse Effects

Vyvanse Pharmacokinetics


Absorption


Bioavailability


Lisdexamfetamine (a prodrug of dextroamphetamine) is rapidly absorbed from the GI tract.1 28 Peak plasma concentrations of lisdexamfetamine occur in approximately 1 hour; concentrations are low and transient; nonquantifiable by 8 hours after administration.1 Peak plasma concentrations of dextroamphetamine occur in approximately 3.5–3.7 hours.1 3 30


Onset


Occurs within 2 hours after oral administration.3


Duration


Approximately 10–12 hours.1 8 27


Food


Food (high-fat meal) delays time to peak plasma concentration of dextroamphetamine by about 1 hour but does not affect magnitude of peak plasma concentration or AUC of dextroamphetamine.1


Distribution


Extent


Amphetamines readily cross the blood-brain barrier and are distributed into most body tissues.26


Amphetamines are distributed into milk in concentrations 3–7 times maternal blood concentrations.21 25


Elimination


Metabolism


Lisdexamfetamine (a prodrug of dextroamphetamine) is converted to l-lysine and dextroamphetamine by first-pass intestinal and/or hepatic metabolism.1


Lisdexamfetamine is not metabolized by CYP isoenzymes.1


Elimination Route


Excreted principally in urine.1 Approximately 96% of a 70-mg radiolabeled oral dose of lisdexamfetamine was recovered in urine; parent drug accounted for about 2% of the recovered radioactivity.1


Changes in urinary pH may alter excretion of amphetamines.1 (See Specific Drugs, Tests, and Foods under Interactions.)


Half-life


Lisdexamfetamine: <1 hour;1 8 dextroamphetamine: 9.4–13 hours.3 8 30


Stability


Storage


Oral


Capsules

Tight, light-resistant containers at 25°C (may be exposed to 15–30°C).1


ActionsActions



  • Amphetamines are sympathomimetic amines with CNS stimulant activity.1 23




  • Lisdexamfetamine is a prodrug of dextroamphetamine; dextroamphetamine may block the reuptake of norepinephrine and dopamine into the presynaptic neuron and increase the release of these monoamines into the extraneural space.1 23 28 30




  • Pharmacologic actions of amphetamines are qualitatively similar to those of ephedrine and include CNS and respiratory stimulation and sympathomimetic activity including pressor response, bronchodilation, and contraction of the urinary bladder sphincter.23 24




  • Theories of dysfunction in ADHD focus on the prefrontal cortex, which controls many executive functions (e.g., planning, impulse control).5 Stimulants have putative effects on central dopamine and norepinephrine pathways that are crucial in frontal lobe function.5




  • Produces an anorexigenic effect, leading to loss of weight.1 5 23 No primary effect on appetite has been demonstrated in humans and it has been postulated that anorexigenic effects are secondary to increased sympathetic activity resulting from release of norepinephrine and dopamine.22



Advice to Patients



  • Provide patient or caregiver with a copy of the manufacturer’s patient information (medication guide); discuss and answer questions about its contents as needed.1 Instruct patient or caregiver to read and understand contents of medication guide before initiating therapy and each time the prescription is refilled.1




  • Advise parents with concerns about long-term effects (e.g., effects on weight) and the need for continued therapy that drug holidays can be considered in consultation with the patient’s clinician.5 6 7 However, the benefits versus risks of such interruptions in therapy have not been established.7




  • Question about possible substance abuse, including in other family members (since they may abuse the patient’s medication supply).1




  • Advise to take drug in the morning to minimize insomnia.1




  • Advise that appetite suppression may occur.1 5 Giving the morning dose with a meal and providing a high-caloric drink or snack late in the evening when the stimulant effects have subsided may be helpful.5




  • Advise to inform clinician immediately if adverse cardiovascular (e.g., chest pain, shortness of breath, fainting) or psychiatric effects (e.g., hallucinations, delusional thinking, mania) occur.1




  • Instruct about the potential for amphetamines to impair patient’s ability to perform potentially hazardous activities, such as driving or operating heavy machinery.1




  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, dietary supplements, and herbal products, as well as any concomitant illnesses/conditions (e.g., cardiac/cardiovascular disease, thyroid disease, glaucoma, suicidal ideation or behaviors, mental/psychiatric disorder, seizures).1




  • Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1




  • Importance of informing patients of other important precautionary information.1 (See Cautions.)

Interferon alfa-2b is often used in combination with another drug called ribavirin (Rebetol). Some of the information in this medication guide applies to the use of both drugs in this combination.

Interferon alfa-2b may also be used for other purposes not listed in this medication guide.


What is the most important information I should know about Intron A (interferon alfa-2b)?


Interferon alfa-2b is often used in combination with another drug called ribavirin (Rebetol). Some of the information in this medication guide applies to the use of both drugs in this combination. Interferon alfa-2b may be harmful to an unborn baby, or may cause a miscarriage. Do not use interferon alfa-2b if you are pregnant, especially if you also take ribavirin (Rebetol). Use 2 forms of effective birth control while you are using this drug combination and for at least 6 months after your treatment ends.

If a man fathers a child while using interferon alfa-2b and ribavirin, the baby may have birth defects. Use a condom to prevent pregnancy during your treatment and for at least 6 months after you stop using this drug combination..


You should not use interferon alfa-2b if you are allergic to interferons, or if you have autoimmune hepatitis, or severe liver problems from causes other than hepatitis B or C.

You should not use the combination of interferon alfa-2b and ribavirin if you have an allergy to either drug, or if you have severe kidney disease, a blood cell disorder, if you are pregnant, or if you are a man and your female sex partner is pregnant.


What should I discuss with my healthcare provider before using Intron A (interferon alfa-2b)?


You should not use this medication if you are allergic to interferons, or if you have autoimmune hepatitis, or severe liver problems from causes other than hepatitis B or C.

You should not use the combination of interferon alfa-2b and ribavirin if you have:



  • severe kidney disease;




  • a blood cell disorder such as thalassemia or sickle cell anemia;




  • if you are allergic to interferons or ribavirin;




  • if you are pregnant; or




  • if you are a man and your female sex partner is pregnant.



If you have any of these other conditions, you may need a dose adjustment or special tests to safely use interferon alfa-2b:



  • diabetes;




  • cancer;




  • bone marrow suppression;




  • a bleeding disorder;




  • a thyroid disorder;




  • breathing problems;




  • a history of depression, mental illness, suicidal thoughts, or drug or alcohol addiction;




  • heart disease, a heart rhythm disorder, or history of a heart attack or blood clots;

  • colitis or other intestinal disorder; or




  • if you have recently received an organ transplant.




This medication may be harmful to an unborn baby, or may cause a miscarriage. Do not use interferon alfa-2b if you are pregnant, especially if you also take ribavirin (Rebetol). The combination of interferon alfa-2b and ribavirin can cause birth defects. Tell your doctor right away if you become pregnant during treatment. Use 2 forms of effective birth control while you are using this drug combination and for at least 6 months after your treatment ends.

If a man fathers a child while using interferon alfa-2b and ribavirin, the baby may have birth defects. Use a condom to prevent pregnancy during your treatment. Continue using condoms for at least 6 months after you stop using this drug combination..


It is not known whether interferon alfa-2b 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.

The powder form of interferon alfa-2b contains albumin, but the solution (liquid) form does not. Albumin comes from human plasma (part of the blood) and may contain viruses and other infectious agents that can cause disease. Although donated human plasma is screened, tested, and treated to reduce the risk of it containing anything that could cause disease, there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.


How should I use Intron A (interferon alfa-2b)?


Interferon alfa-2b is given as an injection into a muscle, under the skin, or directly into a genital wart. The medicine may also be given through a needle placed into a vein.


Your doctor, nurse, or other healthcare provider will give you this injection. You may be shown how to inject your medicine at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles and syringes.

Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.


Do not shake the medication vial (bottle). Vigorous shaking can ruin the medicine. Do not draw your dose into a syringe or IV bag until you are ready to give yourself an injection.

Interferon alfa-2b powder medicine must be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medication. Do not use the mixture if it is not clear or light yellow, or if it has any particles in it. Throw it away and mix another dose.


The single-dose vial of interferon alfa-2b is for one use only. Throw the vial away after measuring your dose, even if there is still some medicine in it. Do not save it for later use. Not all brands, forms, and strengths of interferon alfa-2b are used to treat the same medical conditions. Always check your refills to make sure you have received the correct brand and type of medicine prescribed by your doctor. Ask the pharmacist if you have any questions about the medicine you receive at the pharmacy.

To be sure this medication is not causing harmful effects, your blood will need to be tested on a regular basis. Do not miss any scheduled appointments.


Store interferon alfa-2b in the refrigerator and do not allow it to freeze. After mixing the powder medicine with a diluent, you may store the mixture in the refrigerator but you must use it within 24 hours.

To reduce or prevent certain side effects, your doctor may recommend you take acetaminophen (Tylenol) at the time of your interferon alfa-2b injection. Follow your doctor's instructions about the correct dose.


What happens if I miss a dose?


Use the missed dose as soon as you remember. If it is almost time for your next dose, wait until then to use the medicine and skip the missed dose. Do not use extra medicine to make up the missed dose.


What happens if I overdose?


Seek emergency medical attention if you think you have used too much of this medicine. Symptoms of an interferon alfa-2b overdose are not known.

What should I avoid while using Intron A (interferon alfa-2b)?


If you are being treated for hepatitis or genital warts, avoid having unprotected sex or sharing needles, razors, or toothbrushes. Taking this medication will not prevent you from passing hepatitis or genital warts to other people. Talk with your doctor about safe methods of preventing transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person. Avoid drinking alcohol if you are also taking acetaminophen (Tylenol) while using interferon alfa-2b.

Levothyroxine 50mcg tablets





1. Name Of The Medicinal Product



Levothyroxine 50micrograms Tablets (Thyroxine 50 micrograms Tablets).


2. Qualitative And Quantitative Composition



Each tablet contains 50 micrograms Levothyroxine Sodium anhydrous also known as thyroxine sodium anhydrous.



3. Pharmaceutical Form



Tablet.



White uncoated biconvex tablets engraved on one face FW21 with a breakline on the other.



4. Clinical Particulars



4.1 Therapeutic Indications



Recommended clinical indications: Control of hypothyroidism, congenital hypothyroidism and juvenile myxoedema.



4.2 Posology And Method Of Administration



Adults:



Initially 50 to 100 micrograms daily, preferably taken before breakfast. Adjust at three to four week intervals by 50 micrograms until normal metabolism is steadily maintained: this may require doses of 100 to 200 micrograms daily.



For patients over 50 years, it is not advisable to exceed 50 micrograms daily initially and where there is cardiac disease, 25 micrograms daily or 50 micrograms on alternate days is more suitable initially. In this condition the daily dose may be increased by 25 micrograms at intervals of perhaps 4 weeks.



For patients younger than 50 years, and in the absence of heart disease, a serum Levothyroxine (T4) level of 70 to 160 nanomoles per litre, or a serum thyrotrophin level of less than 5 milli-units per litre should be targeted. For patients aged over 50 years, with or without cardiac disease, clinical response is probably a more acceptable criteria of dosage rather than serum levels.



A pre-therapy ECG is valuable because ECG changes due to hypothyroidism may be confused with ECG evidence of cardiac ischaemia. If too rapid an increase in metabolism is produced (causing diarrhoea, nervousness, rapid pulse, insomnia, tremors, and sometimes anginal pain where there is latent cardiac ischaemia), dosage must be reduced, or withheld for a day or two, and then re-started at a lower dose level.



Elderly: As for patients aged over 50 years.



Paediatric patients:



The maintenance dose is generally 100 to 150 micrograms per m2 body surface area.



For neonates and infants with congenital hypothyroidism, where rapid replacement is important the initial recommended dosage is 10 to 15 micrograms per kg BW per day for the first 3 months. Thereafter, the dose should be adjusted individually according to the clinical findings and thyroid hormone and TSH values.



For children with acquired hypothyroidism, the initial recommended dosage is 12.5-50 micrograms per day. The dose should be increased gradually every 2-4 weeks according to the clinical findings and thyroid hormone and TSH values until the full replacement dose is reached. Infants should be given the total daily dose at least half an hour before the first meal of the day.



When applicable:



Tablets are to be disintegrated in some water (10 to 15 mL) and the resultant suspension, which must be prepared freshly as required, is to be administered with some more liquid (5-10 mL).



4.3 Contraindications



Thyrotoxicosis. Hypersensitivity to any components of Levothyroxine tablets.



4.4 Special Warnings And Precautions For Use



Patient with panhypopituitarism or other causes predisposing to adrenal insufficiency may react to Levothyroxine treatment, and it is advisable to start corticosteroid therapy before giving Levothyroxine to such patients.



Special care is needed for the elderly and for patients with symptoms of myocardial insufficiency, or ECG evidence of myocardial infarction. Thyroid replacement therapy may cause an increase in dosage requirements of insulin or other anti-diabetic therapy. Care is needed for patients with diabetes mellitus and diabetes insipidus.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Levothyroxine increases the effect of anticoagulants and it may be necessary to reduce the anticoagulation dosage if excessive, hypoprothrombinaemia and bleeding are to be avoided.



Acenocoumarol, pheninedione and warfarin enhances the effect of Levothyroxine.



Antiepileptics such as carbamazepine, Phenobarbital, phenytoin, and primidone accelerate metabolism of Levothyroxine (may increase requirements in hypothyroidism) and may displace them from plasma proteins.



Initiation or discontinuation of anti-convulsant therapy may alter Levothyroxine dosage requirements.



If co-administered with cardiac glycosides adjustment of dosage may be necessary. The effect of sympathomimetic agents are enhanced.



Blood sugar levels are raised and dosage of anti-diabetic agents may require adjustment.



Tricyclic anti-depressants response may be accelerated because Levothyroxine increases sensitivity to catecholamines.



Manufacturer of lofepramine advises to avoid Levothyroxine.



Coletyramine reduces the gastrointestinal absorption of Levothyroxine. Oral contraceptives may increase the requirement of thyroid therapy dosage. Other drugs may affect thyroid function tests and this must be considered when monitoring a patient on Levothyroxine therapy.



Rifampicin accelerates metabolism of Levothyroxine (may increase requirements in hypothyroidism).



Phenylbutazone shows false low total plasma-Levothyroxine concentration.



Amiodarone contain iodine and can cause disorders of Levothyroxine function; both hypothyroidism and hyperthyroidism may occur.



Metabolism of propranolol reduces the effect of Levothyroxine.



Sucralfate reduces absorption of Levothyroxine.



4.6 Pregnancy And Lactation



The safety of Levothyroxine treatment during pregnancy is not known, but any possible risk of foetal abnormalities should be weighed against the risk to the foetus of untreated hypothyroidism. Levothyroxine is excreted in breast milk in low concentrations, and it is contentious whether this can interfere with neonatal screening.



4.7 Effects On Ability To Drive And Use Machines



None known.



4.8 Undesirable Effects



Side-effects are usually indicative of excessive dosage and usually disappear on reduction of dosage or withdrawal of treatment for a few days. Such effects include: anginal pain, cardiac arrhythmias, palpitations, cramps in skeletal muscles, tachycardia, diarrhoea, vomiting, tremors, restlessness, excitability, insomnia, headache, flushing, sweating, excessive loss of weight, and muscular weakness.



4.9 Overdose



Signs and symptoms may be an exaggeration of the side-effects, as well as agitation, confusion, irritability, hyperactivity, mydriasis, tachypnoea, pyrexia, increased bowel movements and convulsions. The appearance of clinical hyperthyroidism may be delayed for up to five days. Gastric lavage or emesis is required if the patient is seen within several hours of taking the dose.

5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Levothyroxine 50 micrograms Tablets are tablets containing Levothyroxine sodium used for the treatment of hypothyroidism. Levothyroxine is deiodinated in peripheral tissues to form triiodothyronine which is thought to be the active tissue form of thyroid hormone. Triiodothyronine has a rapid action but a shorter duration of activity than Levothyroxine.



The chief action of Levothyroxine is to increase the rate of cell metabolism.



5.2 Pharmacokinetic Properties



Levothyroxine sodium is incompletely and variably absorbed from the gastrointestinal tract. It is almost completely bound to plasma proteins and has a half-life in the circulation of about a week in healthy subjects, but longer in patients with myxoedema.



A large portion of the Levothyroxine leaving the circulation is taken up by the liver.



Part of a dose of Levothyroxine is metabolised to triiodothyronine.



Levothyroxine is excreted in the urine as free drug, deiodinated metabolites and conjugates. Some Levothyroxine is excreted in the faeces. There is limited placental transfer of Levothyroxme.
