Loratadine and phenylephrine are both active ingredients found in various over-the-counter and prescription medications. Loratadine is an antihistamine, while phenylephrine is a decongestant. When combined, these two ingredients can help alleviate symptoms associated with allergies and sinus pressure. However, it is essential to note that specific uses or formulations of loratadine and phenylephrine may be patented, but the individual ingredients themselves are not.

According to DrugPatentWatch.com [1], there are several patents related to loratadine and phenylephrine combinations. For instance, the patent US9150488B2 [2] is for a "Method of treating allergic rhinitis," which involves administering a specific dosage of loratadine and phenylephrine. Another patent, US9265735B2 [3], is for a "Pharmaceutical composition for treating allergic rhinitis," which also includes loratadine and phenylephrine.

These patents cover specific methods of using loratadine and phenylephrine together, as well as the particular formulations and dosages of these ingredients. However, it is important to note that these patents do not prevent other manufacturers from producing and selling loratadine-phenylephrine combinations, as long as they do not infringe on the patented methods or formulations.

In summary, while loratadine and phenylephrine themselves are not patented, specific uses and formulations of these ingredients in combination may be patented. These patents cover particular methods of administration, dosages, and formulations, which may be subject to legal protections and restrictions.
