See the DrugPatentWatch profile for Claritin
Claritin is a brand name for an antihistamine medication containing the active ingredient loratadine [1]. It is used to relieve allergy symptoms such as sneezing, runny nose, itchy eyes, and watery eyes [1].
How does loratadine work for allergies?
Loratadine is a second-generation antihistamine that works by blocking the action of histamine, a substance in the body that causes allergy symptoms [2]. It selectively binds to peripheral H1 receptors, preventing histamine from binding to these receptors and triggering allergic responses [2].
What are the different forms of Claritin available?
Claritin is available in several forms beyond the standard tablet, including dissolving tablets, liquid gels, and children's liquid formulations [1]. This allows for different administration preferences and age groups.
When does the patent for loratadine expire?
The original patents for loratadine have long since expired, allowing for the widespread availability of generic versions [3]. This patent expiry paved the way for generic competition.
Can I buy generic loratadine instead of Claritin?
Yes, generic versions of loratadine are widely available and are typically less expensive than the brand-name Claritin [4]. These generics offer the same active ingredient and therapeutic benefits.
What are the alternatives to loratadine for allergy relief?
Other antihistamines are available for allergy relief, including fexofenadine (Allegra), cetirizine (Zyrtec), and levocetirizine (Xyzal) [5]. These medications also work by blocking histamine, though they may differ in their specific properties and side effect profiles [5].
