For a 39-year-old woman with a recent diagnosis of psoriatic arthritis who is treatment-naive with mild disease, which of the following would be considered an appropriate first-line therapy?

Choice A reason: Intra-articular glucocorticoids may be used for flare management in specific joints but are not first-line systemic therapy for mild psoriatic arthritis. Choice B reason: NSAIDs are first-line therapy for mild psoriatic arthritis, providing anti-inflammatory and analgesic effects without the risks associated with immunosuppressants. Choice C reason: Opioids are not recommended for arthritis management due to risk of dependence and do not address inflammation. Choice D reason: Pregabalin is indicated for neuropathic pain, not inflammatory arthritis, and is not appropriate for first-line treatment of psoriatic arthritis.
