• Largely determined by oral bioavailability (of oral hydromorphone) • Parab - 50.7 +/- 29.8%; Ritschel – 51.35 +/- 29.3% • Do we need to evaluate conversion from oral to parenteral? • No, because conversion is determined primarily by BAB • Secondarily by pharmacogenetics • Clinical experience in large patient populations provide average guidance • Best data is 1:2.5 (IV:oral) McPherson Table Equianalgesic Doses (mg) Drug Parenteral Oral Hydromorphone 2 5

Reddy A et al. J Pain Symptom Manage 2017;54(3):280-288. Morphine Hydromorphone

• Is it bidirectional? (IV HM to PO MS equal to PO MS to IV HM?) • Study by Lawlor – SQ to SQ HM/MS and PO to PO HM/MS • Going from morphine to hydromorphone (same route) was 5:1 (M:HM) • Going from hydromorphone to morphine (same route) was 3.7:1 (M:HM) • Limitations of Lawlor study: • Data highly skewed and variable, not normally distributed • Authors stated differences in direction were clinically insignificant and called for further research...in the meanme differences in M→HM and HM→M remain speculative

Pain 1997;72(1-2):79-85. How about oral MS to parenteral hydromorphone?

IV HM:PO MS - 1.5:30 IV HM:PO MS – 2:25 Coments Switching from 10 mg IV HM A. Calculate 200 mg PO MS B. Calculate 125 mg PO MS New conversion more per day to PO MS conservative, and it’s consistent with Reddy findings. Switching from 200 mg PO C. Calculate 10 mg IV HM D. Calculate 16 mg IV HM New conversion seems MS per day to IV HM more aggressive than older conversion ratio.

J Diabetes Investig 2017 Metformin – New Cutoffs for Use

• Previously metformin was contraindicated with SCr > 1.4 mg/dl in women of SCr > 1.5 mg/dl in men • Using SCr tends to underestimate renal function in some populations (younger patients, African Americans, patients with greater muscle mass) • New recommendations are based on eGFR: • Contraindicated with eGFR < 30 ml/min/1.73m2 • Therapy not recommended with eGRF between 30 and 45 ml/min/1.73m2 • If eGFR falls below 45 ml/min/1.73m2 benefits and risks should be assessed • Do not administer metformin for 48 hours after an iodinated contrast imaging procedure in patients with eGFR < 60 ml/min/1.73m2 Hypoglycemia – How low can you go?

• About 25% of Americans die in a long-term care facility • Retrospective cohort study of patients > 65 years with T2DM admitted to a VA LTC. • Analysis included: • Cumulative incidence of hypoglycemia (BG < 70 mg/dl) • Cumulative incidence of severe hypoglycemia (BG < 50 mg/dl) • Cumulative incidence of hyperglycemia (BG > 400 mg/dl) • Competing risk of death among all hospice patients • Competing risk of death among patients treated with insulin vs. patients not treated with insulin

Pharmacy Today October 2017 Just Say “NO” to Codeine

• American Academy of Pediatrics advises against giving codeine to children • FDA has now made pediatric use a black box warning • Children, especially those with sleep-disordered breathing, are at particular risk for opioid sensitivity • Codeine can be fatal due to variable metabolism • Majority of deaths occurred with: • Children of young age • Children were on codeine/acetaminophen post-operatively • Children had undergone adenotonsillectomy for sleep-disordered breathing

http://www.usatoday.com/story/news/nation-now/2016/09/22/dont-give-your-children-codeine-academy-pediatrics-says/90831620/ Codeine – World-Class Stinker! Tramadol too!

• FDA further restricted the use of codeine (and hydrocodone) in cough medicines in children under 18. • Risks of misuse, abuse, addiction, overdose, death and slowed or difficult breathing outweigh their benefit. • Single-ingredient codeine and tramadol are FDA approved only for use in adults • Codeine and tramadol should be avoided by breastfeeding mothers • Codeine, given post-stroke, is associated with poorer outcomes • OR for pneumonia 3.8 • OR for stroke worsening 2.7 • OR for death 2

Brain and Behavior 2017;7:e00869 Preventing Urinary Tract Infections

• Cranberry? • MOA – proanthrocyanidin disrupts adhesion of E. coli to the epithelium of the urinary tract, and may prevent infection • Cochrane review evaluated 24 trials comparing cranberry, placebo, no treatment, or water → no difference, and specifically no different in women or seniors • Consider sugar content for patients with diabetes Ok, how about some D-mannose?

• Other options include antibiotic or methenamin prophylaxis • Most common antibiotic regimens are TMP/SMX, trimethoprim, nitrofurantoin, cephalexin, fluoroquinolones at ¼ usual daily dose for 6 months • What about D-mannose? • MOA – inhibition of bacterial adherence to urothelial cells • D-mannose has been used to treat UTI’s in horses, cats and dogs • Been shown to reduce adherence of E. coli, Ps. Aeruginosa, S. zooepidemicus

Kranjcec et al. World J Urol 2014;32(1):79-84. Ok, how about some D-mannose?

• Study in 308 woman 18 years of age with acute UTI and h/o recurrence • Acute UTI treated with ciprofloxacin 500 mg bid for one week • Randomized to 2 g D-mannose powder daily (in 200 ml water), nitrofurantoin 50 mg once a day, or placebo • Placebo – 60% recurrence of UTI • Nitrofurantoin – 20% recurrence of UTI • D-mannose – 15% recurrence of UTI • Fewer adverse effects on D-mannose

• Take several deep breaths to relax neck and throat muscles. • Hold an ice cube or popsicle in your mouth to numb your throat and calm your gag reflex. • Take a drink of water before placing pills on your tongue. • Place the pill on the tip of your tongue. (Others recommend the middle of the tongue. Try both -- see what works for you.) • Don't psych yourself out by thinking "I'm taking a PILL". Think "FOOD."

• What does this mean? • Are they allergic to sulfa, sulfur, sulfites, or sulfates? • “Allergic to sulfa drugs” includes: • Sulfonamide antimicrobials • Sulfamethoxazole-trimethoprim (Bactrim) • Sulfisoxazole-erythromycin (Pediazole) • Sulfonamide non-antimicrobials such as • Celecoxib (Celebrex) • Furosemide (Lasix) • Glimepiride (Amaryl) • Hydrochlorothiazide (HCTZ) • Sumatriptan (Imitrex) What about the extended family?

• Sulfites – occur naturally in some foods during the fermentation process • May be in topical creams and ointments, cosmetic products, Chinese herbs • There is no evidence of cross-allergy between sulfites and sulfonamides • Sulfates – may occur in drugs (morphine sulfate, ferrous sulfate), dietary supplements, personal care products • Very rare for someone to be alleric to sulfates • No cross-allergy with sulfonamide drugs • Sulfur – a chemical element, third most abundant mineral in the human body! Also found in many foods • It would be impossible to be allergic to sulfur and still be alive • Obviously no cross-allergy with sulfonamide drugs! Drug-induced neuropsychiatric events

• Montelukast (Singulair) • Indicated to treat or prevent allergic rhinitis, asthma, bronchoconstriction • Often prescribed for COPD patients • Associated with increased risk of aggression, agitation, depression, suicidal ideation, sleep disturbances • Oseltamivir (Tamiflu) – abnormal ehavior and hallucinations • Varenicline (Chantix) – may cause neuropsychiatric events; BBB removed • Levetiracetam (Keppra) – behavior problems including anger, anxiety, depersonalization, neurosis, personality disorder, aggression Thin – Thick – Thin….ok which is it?
