Cosentyx is a biologic drug that is used to treat various autoimmune diseases, including psoriasis, psoriatic arthritis, and ankylosing spondylitis. However, there is limited information on how this drug affects elderly patients differently [2].

One study suggests that age does not affect the pharmacokinetics of Cosentyx, which means that elderly patients may be able to tolerate the drug similarly to younger patients [3]. However, the study did not evaluate the efficacy and safety of Cosentyx in elderly patients.

Another study analyzed the efficacy and safety of Cosentyx in elderly patients with psoriasis and found that the drug was effective and well-tolerated [1]. However, the study had a small sample size, and the results may not be generalizable to all elderly patients.

Overall, there is limited information on how Cosentyx affects elderly patients differently. Further studies are needed to evaluate the efficacy and safety of the drug in this population. It is important for healthcare providers to carefully monitor elderly patients who are taking Cosentyx to ensure that they are tolerating the drug well and experiencing the desired therapeutic effects [2, 3].
