Pain Flashcards
What type of NSAID is ASPIRIN
prototype
Aspirin belongs to what chemical family
Salicylates
Which NSAID inhibits clotting of blood for a prolonged period of time
Aspirin
Aspirin
Pharmacologic Actions and Therapeutic Use
- Analgesic- the ability to relieve mild to moderate Pain
- Anti-inflammatory- the ability to decrease mild to moderate inflammation
- Antipyretic- the ability to lower body temperature
- Suppression of platelet aggregation- the ability to prevent and/or treat cardiovascular conditions such as acute myocardial infarction (MI) and stroke`
ASPIRIN
Mechanism of Action
blocks the synthesis of prostaglandins by inhibiting the enzyme cyclooxygenase
ASPIRIN
Phatmacokinetics
- Route- PO, rectal
- Absorption- rapid and completely absorbed; enteric aspirin absurd at a different time
- Distribution- widely distributed in all tissues and fluids, does include CNS, crosses the placenta, also in breast milk, and fetal tissues
- Metabolism- metabolized rapidly in liver
- Elimination/Excretion- half life about 6 hrs, renal elimination(by urination)
- On set of action- PO: 5-30 minutes; rectal: 1- 2hours
- Duration of action- PO: 1-4hr; rectal 7hr
ASPIRIN
Potential Adverse Effects
Dyspepsia (upsets stomach, nausea, vomiting) Heartburn Urticaria Tachycardia Tachypnea Diaphoresis TInnitus
ASPIRIN
Tolerance and physical dependence
NO & NO
ASPIRIN
Abuse liability
NO
ASPIRIN
Precautions
anybody with recent history of stomach or intestinal bleeding; people with ulcers or hemophilia(bleeding disorder where blood does not clot normally);
anyone with a history of allergic reactions, asthma, liver and kidney disease;
Anyone with HTN, gout, or heart failure;
If taking aspirin prophylatically then do not take Ibuprofen
ASPIRIN
Category for pregnancy
Category D at 3rd Trimester
ASPIRIN
Drug interactions
be careful taking with
- Chronic use of antacids may decrease the serum salicylate concentration
- SSRI’s- Selective Serotonin Reuptake inhibitors–> can potentiate the risk of bleeding
- Platelet inhibitors
- Hypoglymeic effect of insulin may be potentiated when taken with aspirin
- Can attenuate (taper/block gradually) the effects of anti-hypertensive drugs
- Caffeine may increase the concentration of salicylates–>could be good
- 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
ASPIRIN
Toxicity
Can OD will have a dining in the ears
IBUPROFEN
prototype for
advil and motrin
IBUPROFEN
pharmacologic Actions and Therapeutic Use
Analgesic, anti-inflammatory, antipyrectic(when it impacts the hypothalamus it will increase the peripheral blood flow, causing vasodilation therefor heat will dissapate
IBUPROFEN
Mechanism of action
NON-selective inhibit of cyclooygenase so it inhibits COX1 and COX2
IBUPROFEN
Pharmacokinetics
- Route- PO
- Absorption: 80% is absorbed from the GI tract, peak plasma levels about an hour, half life is 2-4 hrs
- Distribution: highly protein bound, crosses the placenta; not known if secreted in breast milk
- Metabolism: hepatic (extensively metabolized via the liver) rapidly and then we get it out by urination; a little bit ends up in stool
- Excretion: Renal; small amount biliary
- Onset of action: 1hr
- Duration of action: 6-8 hrs
IBUPROFEN
Potential Adverse Effects
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;
