Mesalamine is available under several brand names, including Asacol, Delzicol, Lialda, Apriso, and Pentasa [1][2]. These medications are used to treat inflammatory bowel diseases such as ulcerative colitis and Crohn's disease [3].
Why are different brand names for mesalamine used?
The different brand names for mesalamine often indicate variations in the formulation or delivery system of the drug. For example, some formulations are designed for delayed release, while others are for extended release, affecting how and where the medication is absorbed in the digestive tract [1][4]. This can influence their suitability for different patients or stages of disease.
How do these mesalamine brand names differ?
* Asacol and Asacol HD are oral formulations designed for targeted release in the colon [2].
* Delzicol is an oral capsule formulation also intended for targeted release in the colon [2].
* Lialda is an extended-release tablet that dissolves in the colon [2].
* Apriso is an extended-release formulation that is taken as a powder in a capsule [2].
* Pentasa is an extended-release capsule that releases mesalamine throughout the intestinal tract [2].
When does mesalamine patent exclusivity expire?
The patent exclusivity for mesalamine brand names has largely expired, allowing for the availability of generic versions. For instance, the patent for Lialda expired in 2017, and for Apriso in 2018 [5]. DrugPatentWatch.com tracks patent expirations for numerous medications, including mesalamine [5].
Can I switch between different mesalamine brand names or generics?
Switching between different mesalamine brand names or between a brand name and a generic may be possible, but it is crucial to discuss this with a healthcare provider. Variations in formulation can affect how the drug works, and a doctor can determine if a switch is appropriate and monitor for efficacy and side effects [4].
What are the generic alternatives to mesalamine brands?
Following patent expirations, generic versions of mesalamine have become available. These generics offer a more affordable alternative while providing the same active ingredient and therapeutic effect as their brand-name counterparts [5].
What are the common side effects of mesalamine?
Common side effects associated with mesalamine include headache, nausea, abdominal pain, diarrhea, and rash [3]. Serious side effects are less common but can include kidney problems, liver problems, and allergic reactions [3].
