A recent study of 1,601 patients over the age of 65 years
use a total of 11,180 prescribed drugs =7 drug per person
24 combinations per person (I calculate 30 but the article said 24)
46% of patients with 1 or more known drug–drug interactions identified
The number of combinations leading to subtherapeutic effects was approximately equal to the number leading to potential adverse drug reactions

PPI use for active GI bleeds
Note: pH > 6 necessary for platelet aggregation
Give high dose PPI in active GI bleed (eg Omeprazole 80mg bolus followed by 8mg/hr for 72 hrs after
endoscopic therapy)

PPIs (or any AST) can alter drug and nutrient absorption
Possible B12 and Iron absorption alteration
Ca++ absorption
Weak bases requiring acid for absorption ▪ Griseofulvin, ketoconazole, itraconazole, cefpodoxime for example
HIV medications very sensitive to gastric pH
Any Enteric Coated or delayed release drug may have altered kinetics ©
Chronic use of PPIs: associated with some serious accusations.
Increased risk of community acquired C.Diff infection and other GI infections
Esomeprazole can cross the BBB and has been associated with central fever and severe myalgia
Gastric Suppression and increased risk of CAP
Long-Term PPI use and risk of hip fracture ▪ Ca absorption
▪ In addition to the secretory canaliculi of the gastric parietal cells, the osteoclastic resorption vacuole may be the only other place in which proton pump inhibition by PPIs is known to take place

study of the drug interaction between proton pump inhibitors and clopidogrel
Increased risk of recurrent MI w/I 90 days, pantoprozole not associated w increased risk
Cautionary
Medco Outcomes Stent patients taking PPIs with clopidogrel showed a 32.5% incidence of a major CV event within one year vs. 21.2% of patients not taking PPIs
Cautionary
Aubert RE et al Among angioplasty patients on ASA and clopidogrel, omeprazole significantly reduced the clopidogrel effect
Cautionary
TRITON-TIMI 33% of patients with clopidogrel or prasugrel found no association between PPI use and primary endpoint (CV death, MI or stroke)

Returns to the emergency department 2/11/2010
Transferred from NH for increasing weakness with diffuse ecchymotic rash (mainly upper and lower extremities)
©
The patient initially did well at NH for the 1st week or 2.
Subsequently, started to experience some dyspnea and feeling tired. In the last 10 days or so, she has developed severe diffuse erythematous rash with some petechial aspects. Approximately 3 to 4 days ago, underwent a skin biopsy and the results of this are pending.
At some point during her nursing home stay near the beginning of this month, high INR was noted. The patient received 2 doses of vitamin K IM and her Coumadin has been held since that time. Despite these measures, she has continued to deteriorate and was brought into the emergency room today with diffuse rash, hypotension, and bradycardia.
Previous to January, she was not on any medications. She has no history of diabetes, hypertension, and no history of smoking in the past.
