NSAID, Acetaminophen, DMARDs and Drugs used in Gout Flashcards
Classification of NSAISs
Salicylates - irreversible
Non Selective NSAIDs - reversible
COX 2 Selective
Salicylates
Aspirin
Non Selective NSAIDs
Piroxicam
Ketorolac
Ibuprofen
Indomethacin
COX 2
COXIBs
Non Selective, Irreversible COX 1 and COX 2 inhibitor, Reduces Platelet production of TXA2 -> Red platelet aggregation
Aspirin
Aspirin dosage that decreases platelet aggregation
Follows first order kinetics
Low range <300
Aspirin dosage that is Antipyretic and Analgesic
Intermediate Dose 300-2400
Aspirin dosage that is anti-inflammatory
Follows Zero order kinetics
High Dose 2400-4000
Aspirin Toxic Dose
150 mg/kg or 21 500 mg tabs
Aspirin Lethal Dose
30 g 60 500 mg tabs
Acid base d/o of aspirin
HAGMA + Respiratory Alkalosis
Uncoupler o oxidative phosphorylation
Associated with Reye’s syndrome
Prevents uric acid excretion
Reduces risk of Colon CA
Aspirin
NSAID Non Selective
Reversible COX 1 and COX 2 inhibitor
Inhibits Prostaglandin synthesis
Less GI Bleeding than Aspirin
Ibuprofen
Prevents NSAID induced gastritis
Misprostol
Used to close PDA
Ibuprofen and Indomethacin
Interferes with ASA’s antithrombotic action
NSAIDs
IV NSAID
Non selective reversible COX 1 and COX 2 inhibitor
Post surgical analgesic control, NOT for anti-inflammatory
Ketorolac
Restricted time of use of Ketorolac
72 hours
Non selective reversible COX 1 and COX 2 inhibitor. Inhibits prostaglandin synthesis
Anti-inflammatory (Gout, Arthritis, Ankylosing Spondylitis)
Closure of PDA
COX1>COX2
Has GREATER ANTIINFLAMMATORY EFFECT compared to other NSAIDs
yyIndomethacin
Selective COX-2 inhibitor
Has prothrombotic affect -> MI, Stroke
COX2>COX1
Celecoxib
Preferentially COX2 selective inhibitor
Meloxicam
COX 3 inhibitor
Increased Hepatotoxicity with alcohol
Does not cause Reye’s syndrome
Paracetamol
COX 3 inhibitor Interstitial nephritis
Phenacetin
Antidote of Paracetamol
N - Acetylcysteine
Toxic Dose of Paracetamol
150 mg/kg 21 tabs
Lethal Dose of Paracetamol
15g 30 tabs
