Objectives
Focusing on drugs likely to be used outpatient and already
on the market:
1. Identify basic package insert information (e.g. indication,
dosing, drug interactions) for each drug presented;
2. Compare and contract each new drug to any existing
drugs in the same therapeutic class; and
3. Determine place in therapy of each new drug as
compared to currently available modalities for the indicated
condition(s).

Cost-benefit favors systemic therapy

Topical advantages – no systemic absorption or drug interactions.
Mild, local skin adverse reactions

Topical disadvantages – high cost and lower efficacy

Topical agent with strongest data to support use = efinaconazole

Moving to the Lungs…
STRIVERDI® RESPIMAT® (olodaterol)
STIOLTO™ RESPIMAT® (olodaterol-tiotropium)
6
COPD Treatment Guidelines (GOLD 2015)
 First line = bronchodilators
 No preference for anticholinergic vs beta-agonist
 Long-acting formulations preferred over short-acting
 Combination beta-agonist + anticholinergic reasonable in
patients with severe SOB
 Inhaled steroids indicated for patients with more severe
disease that is unresponsive to bronchodilators alone

Naloxegol (Movantik®) – PLACE IN THERAPY
 AWP pricing per month

Lubiprostone
= $ 377.40

Methylnaltrexone
= $2,594.10

Naloxegol
= $ 299.40
AFTER stimulant or osmotic failure:
•
•
Probably best to try lubriprostone or naloxegol first
•
Naloxegol may be slightly more effective
•
Lubiprostone lacks drug interations
Reserve methylnaltrexone due to cost, subQ route, and higher
incidence of opioid withdrawal
18
Don’t forget the heart…
CORLANOR® (ivabradine)
ENTRESTO™ (sacubitril-valsartan)
19
HFrEF Guidelines for Symptomatic Patients

 Hydralazine-Nitrates for African Americans with NYHA class III-IV if
persistent symptoms despite the above

23
Sacubitril-Valsartan (Entresto™ aka LCZ696)
Indication(s)
HFrEF
Class
Neprilysin inhibitor (combined with ARB)
MOA: increases levels of natriuretic peptides (as well as bradykinin
and adrenomedullin) which leads to vasodilation, diuresis, natriuresis,
and antiproliferative effects and decreased ATII production
How Supplied
24/26 mg, 49/51 mg, and 97/103 mg tablets
49/51 mg po BID, then double q 2-4 weeks to 97/103 mg BID target

• ACE or ARB naïve or only on low dose previously
• eGFR < 30
• Moderate hepatic impairment (avoid use if severe)
Contraindications
Previous ACE or ARB angioedema
Concurrent therapy with ACE inhibitor or aliskiren in DM patients

Ivabradine and Sacubitril-Valsartan:
PLACE IN THERAPY
 Anticipate adoption of sacubitril-valsartan combination by many
cardiologists due to impressive NNT and relative safety
 Ivabradine less impressive – no impact on mortality and concern
over new Afib. Unsure if worth the cost.
AWP pricing per month

Generic HF regimen with ACE or ARB, beta blocker, aldosterone
antagonist and diuretic is under $150

Sacubitril-Valsartan = $225

Ivabradine
(valsartan alone = $150)
