What are the three main effects of NSAIDs?
Analgesic (pain-relieving), antipyretic (fever-reducing), and anti-inflammatory effects
What enzymes do NSAIDs inhibit?
Cyclooxygenase (COX) enzymes, COX-1 and COX-2
What are the three main categories of NSAID side effects?
Gastrointestinal, renal, and cardiovascular
What is the primary function of DMARDs in treating inflammatory arthritis?
Slowing down disease progression
What are four common side effects of DMARDs?
Bone marrow suppression, liver toxicity, gastrointestinal issues, and increased risk of infections
What is unique about Aspirin’s mechanism of action compared to other NSAIDs?
It irreversibly inhibits COX-1 and COX-2
What syndrome can Aspirin cause in children?
Reye’s syndrome
What are three examples of Propionic Acid Derivative NSAIDs?
Ibuprofen, naproxen, and ketoprofen
What type of arthritis are Oxicam Derivatives primarily used for?
Chronic arthritis
What are two examples of Indole Derivative NSAIDs?
Indomethacin and sulindac
What receptors do Fenmate NSAIDs block in addition to COX inhibition?
Prostaglandin receptors
What is an example of a Benzopyrrole NSAID?
Tolmetin
What two mechanisms are involved in the action of Phenylacetic Acid NSAIDs?
COX inhibition and blocking the release of Arachidonic acids
What is the main advantage of Selective COX-2 Inhibitors over traditional NSAIDs?
Lower risk of gastrointestinal side effects
What makes Nimesulide useful for certain patients?
It can be used in patients allergic to aspirin and other NSAIDs
How does Ketorolac compare to Indomethacin in potency?
It is 40 times more potent
What type of drug is Nabumetone?

What cellular process do Calcineurin inhibitors affect?
Dephosphorylation of NF-AT cells, regulating cytokine release
How do DMARDs differ from NSAIDs in their effect on rheumatoid arthritis?
DMARDs target the underlying disease processes, while NSAIDs provide symptomatic relief
What is a major long-term risk of DMARD use?
Increased risk of infections due to immunosuppression
What is the main trade-off when using selective COX-2 inhibitors instead of traditional NSAIDs?
Lower gastrointestinal risk but potentially higher cardiovascular risk
What is Epoprostenol and what is it an analogue of?
Epoprostenol is an analogue of PGI2
