Impax said its generics division, Global Pharmaceuticals, began shipping authorized generic zolmitriptan tablets and orally disintegrating tablets in the 2.5 mg and 5 mg strengths. The drug is a version of AstraZeneca's Zomig.

Zomig had sales of about $196 million during the 12-month period that ended in April, according to IMS Health.
