(rye-zah-trip′tan)
Maxalt, Maxalt-MLT
Func. class.:
Migraine agent
Chem. class.:
5-HT
1D
receptor agonist, abortive agent-triptan
Binds selectively to the vascular 5-HT
1B/1D
receptor subtype; exerts antimigraine effect; causes vasoconstriction of the cranial arteries
Acute treatment of migraine
Angina pectoris, history of MI, documented silent ischemia, Prinzmetal’s angina, ischemic heart disease, concurrent ergotamine-containing preparations, uncontrolled hypertension, hypersensitivity, basilar or hemiplegic migraine
Precautions:
Pregnancy (C), breastfeeding, children, geriatric patients, postmenopausal women, men >40 yr, risk factors for CAD, hypercholesterolemia, obesity, diabetes, impaired renal/hepatic function
Calculator
• Adult:
PO
5-10 mg single dose, redosing separated by ≥2 hr, max 30 mg/24 hr; use 5 mg for patient receiving propranolol, max 15 mg/24 hr
Available forms:
Tabs (Maxalt) 5, 10 mg; orally disintegrating tabs (Maxalt-MLT) 5, 10 mg
•
Orally disintegrating tab:
do not open blister until use; peel blister open with dry hands; place tab on patient’s tongue, where it will dissolve, and have patient swallow with saliva (contains phenylalanine)
CNS:
Dizziness, drowsiness, headache, fatigue
, warm/cold sensations, flushing
CV:
MI, ventricular fibrillation, ventricular tachycardia, coronary artery vasospasm,
palpitations, hypertension, peripheral vascular ischemia, ECG changes
ENDO:
Hot flashes, mild increase in growth hormone
GI:
Nausea
, dry mouth, diarrhea, abdominal pain, ischemic colitis
RESP:
Chest tightness, pressure, dyspnea
Onset of pain relief 10 min-2 hr; peak 1-1½ hr; duration 14-16 hr; 14% plasma protein binding; metabolized in liver (metabolite); excreted in urine (82%), feces (12%); half-life 2-3 hr
Weakness, hyperreflexia, incoordination: SSRIs
Increase:
levels of sibutramine
Increase:
rizatriptan action—cimetidine, oral contraceptives, MAOIs, nonselective MAOI (type A and B), isocarboxazide, pargyline, phenelzine, propranolol, tranylcypromine
Increase:
vasospastic effects—ergot, ergot derivatives, other 5-HT receptor agonists
Serotonin syndrome: St. John’s wort
•
Migraine symptoms:
visual disturbances, aura, intensity, nausea, vomiting, photophobia
•
Stress level, activity, recreation, coping mechanisms
•
Neurologic status: LOC, blurring vision, nausea, vomiting, tingling in extremities preceding headache
•
Ingestion of tyramine foods
(pickled products, beer, wine, aged cheese), food additives, preservatives, colorings, artificial sweeteners, chocolate, caffeine, which may precipitate these types of headaches
•
Renal status: urine output
•
Quiet, calm environment with decreased stimulation: noise, bright light, excessive talking
•
Therapeutic response: decrease in frequency, severity of headache
•
About use of orally disintegrating tab:
instruct patient not to open blister until use, to peel blister open with dry hands, to place tab on tongue, where it will dissolve, and to swallow with saliva (contains phenylalanine)
•
To report any side effects to prescriber
•
To use alternative contraception while taking product if oral contraceptives are being used
•
That product does not prevent or reduce number of migraines; if 1st dose does not relieve pain, do not use more, notify prescriber

Daliresp
Func. class.:
Respiratory anti-inflammatory agent
Chem. class.:
Phosphodiesterase-4 (PDE4) inhibitor
Roflumilast (and the active metabolite roflumilast N-oxide) selectively inhibit phosphodiesterase-4 (PDE4); not a bronchodilator; inhibition of the PDE4 enzyme blocks the hydrolyses and inactivation of cyclic adenosine monophosphate (cAMP), resulting in intracellular cAMP accumulation; decreases inflammatory activity, PDE4 inhibition may affect migration and actions of pro-inflammatory cells (neutrophils, other leukocytes, T-lymphocytes, monocytes, macrophages, fibroblasts)
For the prevention of COPD exacerbations in patients with severe COPD associated with chronic bronchitis and a history of exacerbations
Moderate to severe hepatic disease
(Child-Pugh B or C)
