Rozerem
Func. class.:
Sedative/hypnotic, antianxiety
Chem. class.:
Melatonin receptor agonist
Binds selectively to melatonin receptors (MT

Available forms:
Tabs 8 mg
•
Within 30 min of bedtime for sleeplessness; on empty stomach for fast onset
•

•
Sleep characteristics:
type of sleep problem: falling asleep, staying asleep; complex sleep disorders (sleep walking/driving/eating) after taking product

Storage in tight container in cool environment
•
Therapeutic response: ability to sleep at night, decreased amount of early morning awakening
•
To avoid driving, other activities requiring alertness until product stabilized, drowsiness may continue the next day
•
To avoid alcohol ingestion, CNS depressants
•
About alternative measures to improve sleep: reading, exercise several hr before bedtime, warm bath, warm milk, TV, self-hypnosis, deep breathing
•
To report if pregnancy is planned or suspected (C), avoid breastfeeding
•
To take product immediately before going to bed
•
Not to ingest a high-fat/heavy meal before taking product
To report cessation of menses, galactorrhea (women), decreased libido, infertility, worsening of insomnia, behavioral changes, severe allergic reactions, suicidal thoughts/behaviors, if insomnia gets worse
•
Med guide should be given to patient and reviewed

(ra-mi′pril)
Altace
Func. class.:
Antihypertensive
Chem. class.:
Angiotensin-converting enzyme inhibitor (ACE)
Do not confuse:
ramipril
/enalapril
Altace
/alteplase
Selectively suppresses renin-angiotensin-aldosterone system; inhibits ACE, prevents conversion of angiotensin I to angiotensin II; results in dilation of arterial, venous vessels
Hypertension, alone or in combination with thiazide diuretics; CHF (post-MI), reduction in risk for MI, stroke, death from CV disorders
Unlabeled uses:
Proteinuria due to diabetic nephropathy
Breastfeeding, children, hypersensitivity to ACE inhibitors, history of ACE-inhibitor–induced angioedema
Black Box Warning:
Pregnancy (D) 2nd/3rd trimesters
Precautions:
Geriatric patients, impaired renal/hepatic function, dialysis
patients, hypovolemia, blood dyscrasias, CHF, COPD, asthma, renal artery stenosis, cough, African American patients
