Cards

Term
Aspirin Mechanism
Definition

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

 

Inhibit cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), decreasing the biosynthesis of downstream eicosanoids and thereby limiting the inflammatory response.

Term
Aspirin

Term
List Propionic acids

Term
Adverse effects of Propionic acids, acetic acids, oxicams, fenamates, and ketones
Definition

Term
Piroxicam
Definition
long half-life allows once daily dosing. Inhibits platelets and modulates neutrofils
Term
Nabumetone
Definition
Greatest selectivity of these agents fior COX-2
Term
Important therapeutic consideration for Aspirin
Definition
In contrast to other NSAIDs it acts in an irreversible manner by acetylating the active site serine residue in both COX-1 and COX-2
Term
Mechanism of Acetaminophen
Definition
Weak (reversible) inhibitor of peripheral cyclooxygenases; predominant effect may be inhibition of cyclooxygenase-3 (COX-3) in the CNS.
Term
Clinical Applications Acetaminophen
Definition

-Fever (antipyretic)

-Mild to moderate pain

-no anti-inflammatory properties

-used for children with viral infection in order to avoid Reye's 

Term
Acetaminophen Adverse Effects
Definition
Hepatotoxicity, nephrotoxicity (rare), rash, hypothermia
Term
List of Cox-2 selective inhibitors
Definition

Term
Clinical Applications of Celecoxib
Definition
Osteoarthritis, rheumatoid arthritis, primary dysmenorrhea, acute pain in adults, familial adenomatous polyposis
Term
Adverse Effects of Celecoxib
Definition
Increase thrombosis, myocardial infarction, gastrointestinal bleeding, ulceration, perforation, renal papillary necrosis, exacerbation of asthma
Term
Celecoxib Contraindications
Definition
Asthma, urticaria, allergic-type reactions after taking NSAIDs, due to risk of severe, even fatal, anaphylactic reaction, decrease wound healing, decrease agiogensis
Term
Important therapeutic considerations of Celecoxib
Definition
Withdrawn from market due to possible increased cardiovascular mortality
Term
List of Glucocorticoids
Definition

Prednisone

Prednisolone

Methylprednisolone

Dexamethasone

Term
Mechanism of Glucocorticoids 
Definition

Inhibit COX-2 action and prostaglandin biosynthesis by inducing lipocortins, activating endogenous anti-inflammatory pathways, and other mechanisms

 

Blocks the action of Phospholipase A2. Does not allow Phospholipids to be converted to Arachidonic acids.

Term
List of Cytokine antagonists
Definition

Etanercept

Infliximab

Adalimumab

Anakinra

Term
What do Etanercept, infliximab, and adalimumab inhibit and what else are they used for
Definition

TNF-alpha, rhumatory arthritis, ankylosing spondylitis, psoriatic arthritis, plaque psoriasis, juvenile idiopathic arthritis, Crohn's disease, and ulcerative colitis (2nd one).

 

These increase the risk of serious infections.

Term
What is Anakinra used for
Definition

Rare anemia, rare cardiac arrhythmia, gastrointestinal disturbance, diarrhea

 

Pregnancy

 

PGE1 analogue with vasodilator properties. Also used in peptic ulcer disease. Cytoprotective effects likely mediated by increasing gastric mucus and bicarbonate production, antisecretory effects mediated via inhibition of basal and nocturnal gastric acid secretion by parietal cells
