According to DrugPatentWatch.com, Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels [1]. The effectiveness of Lipitor can be influenced by various factors, including the timing of its administration in relation to meals.

Lipitor is a fat-soluble drug, which means that it can be absorbed more effectively when taken with food, particularly with a meal that contains some fat [2]. This is because fatty foods can increase the absorption of Lipitor in the body, leading to higher drug levels and potentially enhancing its effectiveness [3].

However, it is important to note that taking Lipitor with a high-fat meal can also increase the risk of side effects, such as muscle pain and liver damage [4]. Therefore, it is generally recommended to take Lipitor with a light meal or snack that contains some fat, rather than a large, fatty meal [5].

In summary, taking Lipitor before meals, particularly with a light meal or snack that contains some fat, can enhance its absorption and potentially increase its effectiveness. However, it is important to avoid taking Lipitor with large, fatty meals to minimize the risk of side effects.
