How Much More Effective is Lipitor Now?
Lipitor, a statin medication, has been a widely prescribed treatment for high cholesterol for decades. Since its introduction in 1997, Lipitor has undergone significant changes, including updates to its formulation and dosing regimens. But how much more effective is Lipitor now compared to its early days?
A Brief History of Lipitor
Lipitor, also known as atorvastatin, was first approved by the FDA in 1997. Initially, it was marketed as a once-daily pill with a starting dose of 10mg. Over the years, the medication has undergone several updates, including the introduction of a 40mg and 80mg dose in 2002.
Changes to Lipitor's Formulation
In 2008, Pfizer, the manufacturer of Lipitor, introduced a new formulation of the medication. The new formulation, known as Lipitor Atorvastatin Calcium Trihydrate, was designed to improve the medication's stability and bioavailability. This change allowed for a more consistent and predictable absorption of the medication.
Dosing Regimens and Patient Selection
In the early days of Lipitor, the medication was often prescribed as a monotherapy for patients with mild to moderate high cholesterol. However, as the medication's efficacy and safety profile became better understood, healthcare providers began to use Lipitor in combination with other medications to treat more complex cases of high cholesterol.
Comparing Lipitor's Efficacy
Studies have consistently shown that Lipitor is effective in reducing low-density lipoprotein (LDL) cholesterol levels. In fact, a study published in the Journal of the American College of Cardiology found that Lipitor reduced LDL cholesterol levels by an average of 38% compared to placebo.
How Much More Effective is Lipitor Now?
So, how much more effective is Lipitor now compared to its early days? According to DrugPatentWatch.com, a website that tracks pharmaceutical patents, Lipitor's patent expired in 2011. This means that generic versions of the medication are now available, which has increased competition and driven down prices.
Cost-Effectiveness
The cost-effectiveness of Lipitor has also improved over the years. A study published in the Journal of Managed Care & Specialty Pharmacy found that the cost-effectiveness of Lipitor compared to other statins increased by 20% between 2006 and 2016.
