Impax Receives Approval of Emverm (mebendazole) Chewable Tablets
HAYWARD, Calif., Jan. 15, 2016 /PRNewswire/ -- Impax Laboratories, Inc. (NASDAQ: IPXL) today announced that the United States Food and Drug Administration (FDA) has approved the Company's supplemental new drug application (sNDA) for Emverm (mebendazole) 100 mg chewable tablets.
Emverm is indicated for the treatment of Enterobius vermicularis (pinworm), Trichuris trichiura (whipworm), Ascaris lumbricoides (common roundworm), Ancylostoma duodenale (common hookworm), Necator americanus (American hookworm) in single or mixed infections. Pinworm is a highly contagious parasite that infects approximately 40 million people in the United States each year.1 Pinworm infection is three times more common than head lice.2 Emverm is not for persons who have shown hypersensitivity to the drug.
"We are pleased to announce the approval of Emverm, a new prescription product for the treatment of pinworm and certain worm infections," said Fred Wilkinson, President and Chief Executive Officer of Impax. "Emverm is an important treatment option for pinworm as it offers a 95% clinical cure rate in a single 100 mg dose.3 We currently expect to initiate commercial distribution of Emverm early in the second quarter of 2016."
"As part of our life cycle plan to enhance our anthelmintic franchise in addition to Albenza (albendazole), with this approval, we can now offer an anthelmintic to treat the most common worm infections in the United States. Additionally, the approval of Emverm further leverages the strategic benefits of the Tower Holdings acquisition4," Mr. Wilkinson concluded.
Albenza is indicated for the treatment of parenchymal neurocysticercosis due to active lesions caused by larval forms of the pork tapeworm, Taenia solium. Albenza is also indicated for the treatment of cystic hydatid disease of the liver, lung, and peritoneum, caused by the larval form of the dog tapeworm, Echinococcus granulosus. Albenza is contraindicated in patients with known hypersensitivity to the benzimidazole class of compounds or any components of Albenza.
Emverm (mebendazole) Important Safety Information
Mebendazole is contraindicated in persons who have shown hypersensitivity to the drug
Warnings: There is no evidence that mebendazole, even at high doses, is effective for hydatid disease. There have been rare reports of neutropenia and agranulocytosis when mebendazole was taken for prolonged periods and at dosages substantially above those recommended.
Precautions: Periodic assessment of organ system functions, including hematopoietic and hepatic, is advisable during prolonged therapy.
Information for Patients:
- Patients should be informed of the potential risk to the fetus in women taking mebendazole during pregnancy, especially during the first trimester (See Pregnancy below).
- Patients should also be informed that cleanliness is important to prevent reinfection and transmission of the infection.
Drug Interactions: Preliminary evidence suggests that cimetidine inhibits mebendazole metabolism and may result in an increase in plasma concentrations of mebendazole.
Pregnancy Category C: Mebendazole has shown embryotoxic and teratogenic activity in pregnant rats at single oral doses as low as 10 mg/kg (approximately equal to the human dose, based on mg/m2). In view of these findings the use of mebendazole is not recommended in pregnant women.
Nursing Mothers: It is not known whether mebendazole is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when mebendazole is administered to a nursing woman.
Pediatric Use: The drug has not been extensively studied in children under two years; therefore, in the treatment of children under two years the relative benefit/risk should be considered.
Gastrointestinal: Transient symptoms of abdominal pain and diarrhea with expulsion of worms in cases of massive infection.
Hypersensitivity: Rash, urticaria and angioedema have been observed on rare occasions.
Central Nervous System: Very rare cases of convulsions have been reported.
Liver: There have been liver function test elevations [AST (SGOT), ALT (SGPT), and GGT] and rare reports of hepatitis when mebendazole was taken for prolonged periods and at dosages substantially above those recommended.
Hematologic: Neutropenia and agranulocytosis. (See WARNINGS above).
Overdosage: In the event of accidental overdosage, gastrointestinal complaints lasting up to a few hours may occur. Vomiting and purging should be induced. Activated charcoal may be given.
