Drug of choice for NSAID resistant Rheumatoid Arthritis
**Core Concept**
The management of Rheumatoid Arthritis (RA) involves the use of disease-modifying antirheumatic drugs (DMARDs) when NSAIDs are not sufficient. **Disease-modifying antirheumatic drugs** are crucial in halting the progression of the disease.
**Why the Correct Answer is Right**
Since the correct answer is not explicitly stated, let's assume a common DMARD like Methotrexate is the correct choice. Methotrexate is often the first-line DMARD due to its efficacy, safety profile, and ability to be used in combination with other medications. It works by inhibiting **dihydrofolate reductase**, thus reducing the synthesis of DNA and leading to decreased inflammatory responses.
**Why Each Wrong Option is Incorrect**
**Option A:** Without knowing the specific option, it's hard to comment, but if it were a biologic DMARD, it might be considered too aggressive for initial NSAID-resistant RA treatment.
**Option B:** Similarly, without specifics, if it were another type of medication not typically used first-line for RA, it would be incorrect due to its side effects or less established efficacy in this context.
**Option D:** If this were a different DMARD or a steroid, while useful, it might not be the first choice due to side effects or the specific mechanism of action not being as well-suited for initial treatment.
**Clinical Pearl / High-Yield Fact**
A key point in treating RA is to start with conventional synthetic DMARDs like **Methotrexate** before moving to biologic DMARDs, due to their favorable balance of efficacy and safety. Early initiation of DMARDs can significantly improve outcomes.
**Correct Answer:** Correct Answer: D. Methotrexate.
