Mylan recalls blood pressure med, following recalls of generic by two other drugmakers

Another drugmaker is having to recall metoprolol succinate extended release tablets, a generic for AstraZeneca ($AZN) hypertension drug Toprol XL. This time it is Mylan ($MYL) and the recall is for nearly 16,000 bottles of the beta blocker.

According to the most recent FDA Enforcement Report, Mylan recalled 15,966 bottles of the drug after "A pharmacist reported a rogue tablet of different size and markings in a bottle of metoprolol."

In May, India's Wockhardt voluntarily recalled nearly 110,000 bottles of 50 mg metoprolol succinate extended release. The notice said the drug was made at a Wockhardt facility in Mumbai and that it failed its 9-month dissolution specification test. A month later, India's Dr. Reddy's recalled 13,560 bottles of its version for the same reason.

It is the second recall for Mylan recently, which last month recalled all lots of Mylan-Nitro Spray 0.4 mg/metered dose in Canada because some of them might be missing the "dip tube,"a part of the pump component. It said it might keep users from getting all of the doses of the drug used to treat angina.

A day later, Health Canada revised the recall, saying it had determined an immediate recall might result in a shortage of the product. Mylan suggested that instead, pharmacists provide affected consumers with two new spray canisters of Mylan-Nitro Spray, to make sure they had sufficient doses of the drug.
