61
Q

Levadopa-Carbidopa

too much ACH, too little dopamine

A

-Levodopa crosses the blood brain barrier and becomes dopamine
Carbidopa prevents the metabolism of Levodopa allowing more to cross the blood brain barrier.

62
Q

Levadopa-Carbidopa Side effects & cautions

A

Main side effects are orthostatic hypotension and dizziness **so if pt has HTN –> pt is at risk for falls **

  • Can also cause tardive dyskinesia (uncontrolled involuntary movements) - tongue movements . blinking MUST LET MD KNOW AND FIND ALTERNATIVE OTHERWISE MAY BECOME PERMANENT
  • Med can take up to 3 weeks to work

Should be stopped gradually, to abrupt could lead to increase in Parkinson’s symptoms.

Caution when used with antihypertensive medications. Antacids increase absorption and increase risk of toxicity
Monitor Liver Function
*can not be taken with High protein diet will decrease med absorption / can not be taken with MAOI can cause HTN crisis

63
Q

Myasthenia Gravis meds

A
  • Medications block acetocholinesterase so ACH is in the synapse longer and can produce a better, stronger muscle contraction
  • Cholinestraise Inhibitor ** increase strength less fatigue
  • Fast acting for diagnosis: endonorphium* (TESTER & will make muscle stronger if they have Myasthenia Gravis)
  • Long acting for treatment: pyridostigmine*
64
Q

Pyridostigmine

A

(SLUDGE)- cholinergics
PO medication
-Used to effect activity at the nicotinic (skeletal muscle) but could effect the muscarinic (smooth muscle) leading to parasympathetic side effects.
-Contraindicated in intestinal and urinary obstruction.
Reversal is atropine. for muscle weakness respiratory paralysis that occurs within 1 hr of admin = serum level too high.

65
Q

Serotonin Reuptake Inhibitors
Depression Med
Focus on seratonin
Sertraline (SSRI)

A

-Oral
-As pill or liquid
-If liquid must be mixed with another liquid like water, white soda, or OJ
-Takes 2-4 weeks for onset of action (difficult to predict half life because is highly protein bound)
-Agitation, insomnia, headache, dizziness, somulene
Increased risk of suicide ideation
*risk of increased Weight- instruct healthy food for pt
risk of sexual dysfunction

66
Q

Depression- Imiprimide (TCA)

A

Blocks reuptake of serotonin and norepinephrine
(Happy/ motivation/ increased mood but decreased in ACH and anticholinergic)
Takes at least 2 weeks to work
*Can also cause anticholinergic side effects : HTN/increased HR/ dry mouth -urniation hesitation
-Can cause diaphoresis (diabetics)

Increased risk of suicidal ideation (when you first start med)
Contraindicated in MI, bundle branch block, glaucoma, kidney or liver impairement
**causes dangerous heart failure/ Cardiac SE)

67
Q

Depression Med

Phenelzine (MAOi)

A

Phenelzine (Nardil)
Inhibits MAO leaving norepinephrine in the synapse
*Keeping NE & Seratonin & Dopamine linger in the synapse *

  • Cannot be used in cardiovascular, cerebrovascular, -hepatic/renal impairment, or pheochromocytoma.
  • Cannot use with TCA or SSRI as will cause severe temperature elevations and seizures.
68
Q

Bipolar-Lithium

A

Mood Stabilizer: Lithium

  • Narrow therapeutic range: 0.6-1.5 mEq/ml REMEMBER
  • Relationship with sodium
  • Low sodium can cause lithium toxicity (can cause profound hypo htn & causes cardiac arrest)

69
Q

Drugs that make the cell less positive (decrease sodium in the cell)
Phenytoin- (Dilantin)

A

IV : When someone comes in seizure

  • Mixed with saline only. If mixes with dextrose will precipitate which can lead to embolus (always flush extra)
  • -** Start a new line other arm or Start a new IV line**
  • Use large vein or central line

Q

Medications Affecting Platelets
Blocking ADP receptors
Clopidogrel (Plavix)

A
  • Stops platelets from binding sites from binding for 7 days*
  • Given to prevent clots in patient with recent MI, CVA, or PAD.
  • Prevention in unstable angina, those receiving PCI or stent
  • Irreversibly binding the receptor for ADP, lasts the life of the platelet

Do not crush or split
Flulike syndrome, HA, dizziness, bruising, rash , prurutis
Bleeding

  • when treatment is effective: no more CVA/ MI
  • Eat with food/ milk

75
Q

Medications Affecting Clotting Factors

Heparin

A

Hold 12 hrs before SX/ works around factor Xa

  • Binds to anti-thrombin III inactivating several clotting factors
  • Works immediately when given IV. Works in an hour when given SQ.
  • Weight based monogram based on use
  • With SQ do not draw back on syringe or massage area
  • Bleeding
  • Heparin induced Thrombocytopenia (if platelets are already low- heparin will lower it even more)
  • Epidurals
  • Overdose: Protamine Sulfate, given IV, 1mg for every 100u of heparin
  • Give deep into fat tissue SQ - put pressure for 1-2 min to decrease bruising *

Heparin will also treat evolving clot - IV will prevent clot from getting bigger & body will try to get rid of clot

92
Q

Uterine Stimulants

Oxytocin

A
  • Monitoring of mother (HR/ BP) & infant (HR)
  • Continuous monitoring of maternal blood pressure, heart rate, and uterine contractions
*Uses:	Must be on IV pump  *
Induction of labor (postterm, premature rupture of membranes, preeclampsia)
-Enhance labor
-Delivery of placenta
-Control of postpartum bleeding
-Fetal stress testing

Intranasal: promotion of milk letdown

Every time there is a contraction baby gets less blood - prolong contraction = danger for baby

93
Q

Oxytocin- Adverse Events

A

-Antidiuretic effect (water intoxication)

uterine hyperstimulation could lead to uterine rupture

  • Contractions > 60 seconds
  • Contractions more frequently than every 2-3 minutes
    • First thing you want to do in Emergency -Turn patient on LEFT side, stop infusion and administer oxygen.** (decrease pressure on baby )
    • contractions less than 1 min and
  • Administer a uterine relaxant like Terbutaline

premature ventricular contractions
hypotension mild and transient hypertension

94
Q

Terbutaline

A

Tocolytics are medications used to suppress premature labor.

Goal: postpone delivery long enough to reduce incidence of problems associated w/prematurity.

The therapy buys time for the administration of steroids to accelerate fetal lung maturity and/or transport mom to high risk facility. Tocolytic therapy is less likely to be effective if cervical dilation is > 6 cm

**Uterine Relaxant: Smooth muscle relaxation uterus- Decrease in BP + reflux tachy + Vasodilation **

** Mom would be on monitor for HR for mom + infant**

95
Q

Terbutaline

Adverse Effects

A

Adverse effects
Tachycardia, palpitations, chest pain, arrhythmias
Tremors, anxiety, headache
