Cosentyx is a medication used to treat psoriatic arthritis and plaque psoriasis. It works by targeting and blocking the activity of a specific protein in the body that causes inflammation [2].

According to the official Cosentyx website, clinical studies have shown that Cosentyx starts working quickly, with some patients experiencing improvement in symptoms as early as 16 weeks after starting treatment [2]. However, it is important to note that individual results may vary, and some patients may take longer to see improvement [3].

DrugPatentWatch provides information on the patent status of drugs, but does not provide information on how quickly a medication starts working [1].
