Q

ASPIRIN

Drug interactions

A

be careful taking with

  1. Chronic use of antacids may decrease the serum salicylate concentration
  2. SSRI’s- Selective Serotonin Reuptake inhibitors–> can potentiate the risk of bleeding
  3. Platelet inhibitors
  4. Hypoglymeic effect of insulin may be potentiated when taken with aspirin
  5. Can attenuate (taper/block gradually) the effects of anti-hypertensive drugs
  6. Caffeine may increase the concentration of salicylates–>could be good
  7. Alcohol(ETOH)- not a good idea because it can cause stomach bleeding and when we take an NSAID with it we can potentiate the bleeding

Q

IBUPROFEN

Pharmacokinetics

A
  1. Route- PO

  3. Distribution: highly protein bound, crosses the placenta; not known if secreted in breast milk
  4. Metabolism: hepatic (extensively metabolized via the liver) rapidly and then we get it out by urination; a little bit ends up in stool
  5. Excretion: Renal; small amount biliary

Q

IBUPROFEN

Potential Adverse Effects

A

Peripheral Edema (unusual)
Fluid Retention
Dyspepsia
Flatulence
CNS affects: dizziness(unusual), nervousness(unusual), lightheadedness, headaches
Photosynthesizing agent–> easy to sunburn while taking
REGULAR USE WILL SOMETIMES EXACERBATE ASTHMA, SOMETIMES FATALLY
Lower dose/usual doses of Ibuprofen seems to have the lowest incident of digestive ADRS(Adverse Drug Reactions) of all nonselective NSAIDS;

Q

IBUPROFEN

OD symptoms

Study These Flashcards
A

lethargy, vertigo, tinnitus, CNS depression, convulsion/seizures. Treatment is activated charcoal and a laxative

Q

IBUPROFEN

Tolerance and physical dependence

21
Q

IBUPROFEN

Abuse liability

22
Q

IBUPROFEN

Precautions

Study These Flashcards
A

those with known allergies to aspirin or other NSAIDS
Patients with liver problems(taking Ibuprofen as you should can elevate liver function test by 10-15%, and can cause liver failure)
Sever uncontrolled hypertension
Congestive heart failure CHF, can bring on anemia
Bleeding adnormalities
history of GI Bleeding
impaired renal or hepatic function

23
Q

IBUPROFEN

Pregnancy Category

Study These Flashcards
A 
Category B (first and second trimesters)
Category D (third trimester)
24
Q

IBUPROFEN

Drug interactions

Study These Flashcards
A

can make some antihypertensive actions less effective;
Use with other NSAIDS, alcohol, or corticosteriods may cause serious adverse GI events;
1. patients taking diuretics have shown a decrease in the effectiveness of said diuretics–> reduce desired effect & not peeing out fluid
2. Lithium can increase plasma levels of lithium causing toxicity;
WARFARIN w/NSAIDS will increase GI bleeding, antacids are ok

25
IBUPROFEN | toxicity
one overdose can destroy your liver(renal failure), apnea, cyanosis, drowsiness, GI bleeding, nausea, vomiting, and sweating; Can be life threatening complications
26
What has long term use of NSAIDS and ibuprofen been linked to?
1.4 times likely to have erectile dysfunction
27
IBUPROFEN | Food precautions
take under fasting conditions; without food
28
CELECOXIB has what type of warning
BLACK BOX warning--> may cause higher risk of heart attack or stroke; New onset or worsening HTN; it could kill you; used mostly for RA
29
CELECOXIB | Pharmacologic Actions and Therapeutic Use
Anti-inflammatory, | Approved to treat mild to moderate pain and inflammation associated with RA, osteoarthritis, dysmenorrhea
30
CELECOXIB | Mechanism of action
inhabitation of prostaglandins COX2, NSAID
31
CELEXOCIB | Pharmacokinetics
Route- PO; 3hrs to reach desired plasma levels;3-5 days to get steady level Absorption- well absorbed Distribution- widely distributed;is likely secreted in breast milk, 97%(HIGHLY PROTEIN BOUND) stays a long time Metabolism- CP450 Excretion- via liver primarily feces, with some in urine
32
CELEXOCIB | Potential Adverse Effects
``` Dyspepsia diarrhea flatulence peripheral edema (UNUSUAL( URI(upper respiratory infection) -UNUSUAL ex. sinusitis, pharyngitis, rhinitis ```
33
CELEXOCIB | Tolerance and Physical Dependence
NONE & NONE
34
CELEXOCIB | abuse liability
NONE
35
CELEXOCIB | Precautions
people that are allergic, people with history of asthma, be careful using it preoperatively with patient having coronary artery bypass graft (CARB); patients with known cardiovascular disease or risk factors may be at increased risk for death; people with elevated liver enzymes. GI issues can be potentially fatal, PUD(peptic ulcer disease), Celebrex- CAN CREATE NEW ONSET OR WORSENING OF HYPERTENSION; BP SHOULS BE MONITORED FREQUENTLY WITH CELEBREZ, CAUTIOUS WITH ELDERLY, RISK FOR SJS(STEVEN JOHNSON SYNDROME)
36
CELEXOCIB | pregnancy category
category c | and later D in third trimester
37
CELEXOCIB | Drug interactions
don't take with antihypertensive because it may make them not work as good; Warfarin is fine might increase lithium levels Don't take with aspirin because increase GI bleeding Don't use with alcohol, corticosterioids, or other NSAIDS may cause serious adverse GI events. Decreases lasix effects
38
CELEXOCIB | Toxicity
overdose may cause acute renal failure, apnea, cyanosis, drowsiness, GI bleeding, and nausea, vomiting and sweating. OD is treated with administration of activated charcoal and nasogastric suction
39
ACETAMINOPHEN (Tylenol) Pharmacologic Actions and Therapeutic Use
Synthetic non-opiod centrally acting analgesic, antipyretic works differently
40
Tylenol | Mechanism of Analgesic Action
Reduces fever acts centrally in the CNS by inhibiting COX; no effect on COX in peripheral tissues; May also inhibit the chemical mediators of pain, but its mechanism is unclear
41
Tylenol | Pharmacokinetics
1. Route: PO; rapidly and almost completely absorbed via the gut; elate bioavailability ranges between 85%-95; there is an injectable form also 2. Absorption: rapid and complete. BIOAVAILABILITY 85-98% 3. Distribution: widely distributed throughout most body fluids EXCEPT ADIPOSE TISSUE, crosses the placenta, has a hard time getting into fat, secreted into breast milk; 25% protein bound 4. Metabolism: primarily liver (hepatic), half-life 2-3 HOURS 5. Excretion: Renal; half life of 2-3 hours 6. On set duration: 30-60 minutes 7. Duration of ACtion: 3-8 hours
42
Tylenol | Potential Adverse Effects
serious adverse effects are rare; excessive use in the US in then number one cause of acute hepatic failure; first suicide attempt/OD can kill your liver
43
Tylenol | Precautions
use caution when giving to patients with RA, can worsen patient with renal impairment
44
Tylenol | Pregnancy Category
Category B
45
