Over 140,000 bottles of the most commonly prescribed medication in the United States are being recalled due to concerns about their effectiveness. Ascend Laboratories, a pharmaceutical company headquartered in New Jersey, has decided to withdraw its generic version of Lipitor, known as atorvastatin calcium, from the market. This decision stems from worries that the tablets may not dissolve as intended.

The recall impacts various dosages of the medication, specifically 10mg, 20mg, 40mg, and 80mg tablets. These were distributed across the nation in bottles containing 90, 500, or 1,000 tablets, all available by prescription.

The Food and Drug Administration (FDA) issued a recall notice indicating that the affected drugs did not meet dissolution specifications. This means that during testing, the tablets failed to release their active ingredient at the anticipated rate, which could result in patients receiving an incorrect dosage.

This malfunction might lead to patients absorbing either an excessive or insufficient amount of the medication, potentially impacting its effectiveness. However, the FDA has not reported any illnesses or injuries linked to these tablets on their official website.

This could mean that someone taking the statins may receive too much or too little of the medication because it is not being released from the tablet correctly.

No illnesses or injuries due to the drugs were revealed on the agency’s website.

The recall was revealed last month in an FDA enforcement report but the agency has not issued a public notice or guidance on what to do if you are impacted by the recall.

However, in similar cases, consumers are typically advised to contact their doctor immediately.

The manufacturer, Ascend Laboratories, has not made a statement in response to the recall and did not respond to a Daily Mail request for comment.

Statins are the most commonly prescribed drug in the US, with more than 818million prescriptions written every year. 

Atorvastatin is among the most common, taken by more than 29 million people in 2023, with 115 million prescriptions written in that year. 

Statins are used to lower cholesterol levels in the body, with studies suggesting they can reduce the risk of heart attacks, strokes and premature death.

High cholesterol is when there are elevated levels of cholesterol, a waxy substance, in the blood.

When levels are high, there is concern that excessive amounts can accumulate in the arteries and cause them to narrow, raising the risk for heart disease.

An estimated 86million adults in the US have high cholesterol.

Customers can find out whether their statins are part of the recall by checking the LOT number, which is usually printed on the top or the side of the bottle.

The FDA has published a full list of the LOT numbers affected on its website.

The recall is considered a Class II, meaning using the pills may cause a ‘temporary’ reaction, although the risk of long-term injury is ‘remote’.

The tablets were made by Alkem Laboratories, based in India, and then repackaged and sold under Ascend Laboratories in the US, which is owned by Alkem.

People on atorvastatin generally take one tablet once a day.

The tablets are normally rapidly absorbed by the body, with the drug reaching its maximum concentration in the body within about one to two hours of taking the drug.

After 14 hours, levels of the drug drop by half, studies suggest, while one tablet is completely removed from the body after 77 hours, or three days.

The recall for ‘failed dissolution specifications’ suggests the recalled statins did not release the drugs at this rate, although it is not clear whether it was faster or slower than usual. 

Atorvastatins are available from numerous manufacturers since the drug’s patent expired in 2011, including Pfizer, Teva Pharmaceuticals and Dr Reddy’s Laboratories.

There are no recalls related to the statin made by those companies.
