FDA Approves Lamictal(R) ODT(TM) Orally Disintegrating TabletsEasy-to-swallow formulation provides important new alternative for patients
RESEARCH TRIANGLE PARK, N.C., May 11 (Healthcare Sales & Marketing Network) -- GlaxoSmithKline (NYSE: GSK ) announced today that the U.S. Food and Drug Administration (FDA) has approved Lamictal® ODT(TM) (lamotrigine) Orally Disintegrating Tablets. Lamictal ODT uses a novel drug-delivery formulation to provide Lamictal in a tablet that has a pleasant taste and disintegrates on the tongue.
One factor physicians should consider when treating chronic disorders is whether patients can swallow the medications they need. In one large survey study, 23 percent of patients in a general practice setting reported difficulty swallowing.
"Patients with epilepsy or bipolar disorder can have difficulty swallowing tablets. Unfortunately, this problem may go unrecognized, because many patients don't discuss this issue with their healthcare providers," said Daniel Lieberman, M.D., associate professor and clinical director of the George Washington University Department of Psychiatry and Behavioral Sciences. "Orally disintegrating tablets, like Lamictal ODT, offer an option for patients who have difficulty swallowing tablets."
Lamictal ODT was approved based on the demonstrated bioequivalence of Lamictal ODT to Lamictal Tablets and was developed in collaboration with Eurand N.V. (Nasdaq: EURX ). Lamictal ODT is the only antiepileptic treatment that is available in an orally disintegrating formulation.
Lamictal ODT is indicated for the long-term treatment of Bipolar I Disorder to lengthen the time between mood episodes in people 18 years or older who have been treated for mood episodes with other medicine. It is not known if Lamictal ODT is safe or effective in children or teenagers under the age of 18 with mood disorders such as bipolar disorder or depression. Lamictal ODT is also used together with other medicines to treat certain types of seizures (partial seizures, primary generalized tonic-clonic seizures, generalized seizures of Lennox-Gastaut syndrome) in people two years or older or alone when changing from other medicines used to treat partial seizures in people 16 years or older. It is not known if Lamictal ODT is safe or effective when used alone as the first treatment of seizures in adults.
Lamictal ODT will be available in 25 mg, 50 mg, 100 mg, and 200 mg strengths and is expected to be available in pharmacies in early July. For patients switching from Lamictal Tablets to the ODT formulation, the recommended dose of Lamictal ODT matches the dose of Lamictal Tablets. For patients new to Lamictal, Patient Titration Kits containing five weeks of treatment will be available. Lamictal ODT will also be available in four Maintenance Packs, one Pack for each dose strength. These Packs each contain 30 tablets and are designed to help make it easy for patients to keep up with their daily dose.
Prescription Lamictal ODT Tablets are not for everyone. Lamictal ODT is another form of Lamictal. Lamictal may cause a serious skin rash that may cause the patient to be hospitalized or to stop Lamictal; it may rarely cause death. There is no way to tell if a mild rash will develop into a more serious reaction. These serious skin reactions are more likely to happen when the patient begins taking Lamictal, within the first two to eight weeks of treatment. But it can happen in people who have taken Lamictal for any period of time. Children between two to 16 years of age have a higher chance of getting this serious skin reaction while taking Lamictal.
The risk of getting a rash is higher if taking Lamictal while taking valproate (Depakene® (valproic acid) or Depakote® (divalproex sodium)), taking a higher starting dose of Lamictal than a healthcare provider prescribed or increasing the dose of Lamictal faster than prescribed.
Lamictal can also cause other types of allergic reactions or serious problems which may affect organs and other parts of your body like the liver or blood cells. The patient may or may not have a rash with these types of reactions.
The patient should call their healthcare provider right away if they have any of the following: a skin rash, hives, fever, swollen lymph glands, painful sores in the mouth or around the eyes, swelling of the lips or tongue, yellowing of the skin or eyes, unusual bruising or bleeding, severe fatigue or weakness, severe muscle pain or frequent infections. These symptoms may be the first signs of a serious reaction. A healthcare provider should examine the patient to decide if they should continue taking Lamictal.
Antiepileptic drugs, including Lamictal, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any antiepileptic drug for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, or any unusual changes in mood or behavior.
Patients, their caregivers, and families should be informed that antiepileptic drugs increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of the signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self-harm. Behaviors of concern should be reported immediately to healthcare providers.
Medication errors involving Lamictal have occurred. In particular, the name Lamictal or lamotrigine can be confused with the names of other commonly used medications. Medication errors may also occur between the different formulations of Lamictal. To reduce the potential of medication errors, healthcare professionals should write and say Lamictal clearly. Depictions of the Lamictal Tablets, Chewable Dispersible Tablets, and Orally Disintegrating Tablets can be found in the Medication Guide that accompanies the product to highlight the distinctive markings, colors, and shapes that serve to identify the different presentations of the drug and thus may help reduce the risk of medication errors. To avoid the medication error of using the wrong drug or formulation, patients should be strongly advised to visually inspect their tablets to verify that they are Lamictal, as well as the correct formulation of Lamictal, each time they fill their prescription.
Patients should not take Lamictal or Lamictal ODT if they have had an allergic reaction to lamotrigine or to any of the inactive ingredients.
Common side effects include dizziness, headache, blurred or double vision, lack of coordination, sleepiness, nausea, vomiting, insomnia, tremor, rash, fever, abdominal pain, back pain, tiredness, and dry mouth. Patients should tell their healthcare provider about any side effect that bothers them or does not go away; patients should tell their healthcare provider if they have any changes in their menstrual pattern, such as breakthrough bleeding, while taking Lamictal and birth control pills. These are not all the possible side effects of Lamictal.
