UNIT 4: MEDS TO KNOW Flashcards
What class of medication is Naloxone?
Opiod antagonist; Antidote
Route of admin for Naloxone?
- IV (preferred)
- IM
- Sub q
- Inhalation
- IO
- oral
What are some warnings/precautions of naloxone?
- Acute opiod withdrawl
- R/t release of catecholamines which may precipitate acute withdrawal or unmask pain in those who regularly take opiods
- Combativeness
- Some patients may be agitated or combative when resuscitated with naloxone.
- Caution w/cardiovascular disease
- Seizures
- Opioid overdose symptom recurrence
- Recurrance of resp. and/or CNS depression is possible if the opiod involved is long-acting.
How long do you push naloxone?
Over 30 seconds as undilutaed or admin lower doses as a slow IV push.
What is the medical indication for the use of Naloxone?
For complete or partial reverasal of opioid toxicity (including resp depression) induced by natrual and synthetic opiods (methadone). It is also indicated for the diagnosis of suspected or known acute opiod overdosage
What is the MOA of naloxone?
Pure opioid antagonist that competes and displaces opiods at opioid receptor sites
What should we monitor for a patient who recieved naloxone?
- Resp status (oxygenation and ventilation)
- LOC
- HR
- BP
- Temp
- S/s of opioid withdrawal
q
What are s/s of acute withdrawal in opiod-dependant patients?
- pain
- tachycardia
- hypertension
- fever/sweating
- abdominal cramps
- n/v/d
- agitation/irritability
What pharm class is Flumazenil
Benzodiazepine antagonist
What is the MOA of flumazenil?
Completely inhibits the activity at the benzodiazepine receptor site on the GABA/benzodiazepine receptor complex.
Flumazenil does not antagonize the CNS effect of drugs affecting GABA-ergic neurons by means other than the benzo receptors (ethonal, barbiturates, general anesthetics) and does not reverse the effects of opiods
What dietary considerations should we teach patients taking flumazenil?
avoid alochol for the 1st 24 hours after administration or as long as teh effects of benzos exist
What should we monitor for a patient when taking flumazenil?
- sedation, resp depression
- benzo withdrawals
monitor for at least 3 hours and until the patient is stable and resedation is unlikly.
What are some adverse reactions of flumazenil?
- Vomiting
- Cardiovascular flushing, palpitations, vasodilation
- Diaphoreisis
- Agitation
- Dizziness
- Blurred visision
- Confusion, lack of concentration
- Hiccups
What are some percautions we should keep in mind with flumazenil?
- Amnesia
- CNS depression
- Resedation
- Resp depression
- Seizures
What is the black box warning for flumazenil?
Benzo reversal may result in seizures
What pharm class is gabapentin?
Antiseizure
What should we inform patient to do when quitting gabapentin?
should be withdrawn gradually over 1 week or more to minimize the potential of increased seizure frequency or withdrawal symptoms
What are some clinical uses of gabapentin?
- Seizure prevention
- Epilepsy tx
- Neuropathic pain
- restless leg syndrome
What are some side effects of gabapentin?
- Signs of an allergic reaction: hives, itching, swelling, blistered or peeling skin, difficulty breathing
- Changes in mood or behavior
- Signs of liver abnormailities: yellowing of skin, whites of eyes, dark urine, light-colored stools, vomiting, unusal bleeding/bruising
- Signs of kidney abnormabilites: Trouble urinating, a change in how much urine is passed, blood in your urine, weight gain, swelling in legs and feet
- change in skin color, bluish color on skin, lips, nail beds
More common
1. tired
2. dizzy
3. headache
4. n/v
5. fever
6. recurring infections
7. memory loss
8. weight gain
9. eye problems
what is the clinical indication for gabapentin?
Indicated for the tx of postherpetic neuralgia in adults and for the adjunctive tc of partial onset seizure
What is the MOA of gabapentin
Inhibits the release of excitatory neurotransmitters
