Singulair, usually taken in the form of tablets, has been a blockbuster drug for Merck. The company has said that it expects sales to drop by 90% as generic montelukast hits the market. Singulair sales were $1.43 billion in the last quarter before the generic announcement.
Apotex Inc., Aurobindo Pharma, Endo Pharmaceuticals, Glenmark Generics, Kudco Ireland Inc., Mylan Inc., Roxane Laboratories, Sandoz Inc., Teva Pharmaceuticals Inc., and Torrent Pharmaceuticals have gained FDA approval for generic montelukast tablets.
Apotex, Aurobindo, Endo, Kudco, Mylan, Roxane, Sandoz, Teva, and Torrent have received approval for chewable tablets. Teva has received approval for the oral granule form.
The drug is not intended for sudden asthma attacks. And side effects can be serious. People taking montelukast should get immediate medical help if they experience:
- Mood or behavior changes such as aggression or depression
- "Pins and needles" feeling or numbness in the arms or legs
- Flu-like symptoms
- Severe sinus pain
In clinical trials, common side effects in patients taking Singulair were upper respiratory infection, fever, headache, sore throat, cough, stomach pain, diarrhea, earache, flu, runny nose, and sinus infection.
To get FDA approval, generic drugmakers have to make a product with the same manufacturing, packaging, and quality standards as the name-brand product.
