Common indications for celecoxib
Nonsteroidal anti-inflammatory
For the relief of osteoarthritis Relief of the signs and symptoms of rheumatoid arthritis in adults
For the management of acute pain and dysmenorrhea
MOA of celecoxib
Inhibits prostaglandin synthesis by decreasing the activity of the enzyme, cyclooxygenase-2 (COX-2), which results in decreased formation of prostaglandin precursors; has antipyretic, analgesic, and anti-inflammatory properties.
Common AEs of celecoxib
Diarrhea Dyspepsia Abd pain Flatulence Edema Bleeding
Renal or hepatic dose adjustments for celecoxib
Advanced renal disease: Use is not recommended, Moderate hepatic impairment: Reduce dose by 50%.
Severe hepatic impairment: Use is not recommended.
BBW for celecoxib
Celecoxib may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction (MI), and stroke, which can be fatal.
NSAIDs, including celecoxib, cause an increased risk of serious gastrointestinal (GI) adverse events, including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal.
Clinically significant drug interactions for celecoxib
May increase the effects of warfarin
Major counseling points of celecoxib
May be taken without regards to meals
Report any signs of ulcerations and bleeding to a physician
Avoid ASA or ASA containing products
Pay close attention to sudden mood change and suicidality
Monitoring parameters of celecoxib
Decrease the S/S of inflammatory conditions, rheumatoid arthritis, dysmenorrhea, improvement in S/S pain
Common indications of benzonatate
Symptomatic relief of cough
MOA of benzonatate
Tetracaine congener with antitussive properties Suppresses cough by topical anesthetic action on the respiratory stretch receptors

Monitoring parameters of benzonatate
Relief of cough/antitussive effects
Common indications of sildenafil

Pulmonary HTN
MOA of sildenafil

No more than one dose per day
Monitoring parameters of sildenafil
Decrease in S/sx of ED/pulmonary HTN

MOA of bupropion
Weak inhibitor of neuronal uptake of NE, serotonin, and dopamine
Common AEs of bupropion
Tremor
Wt loss

Renal or hepatic dose adjustments for bupropion
Hepatic/renal: consider reducing dose and frequency
BBW for bupropion
Suicidality
Clinically significant drug interactions for bupropion
EtOH may lower seizure threshold
Toxicity is increased by MAO-Is
Chronic use with NSAIDs increases risk of GI bleeds
Major counseling points for bupropion
