Q

Mechanism of Action of Anti-platelet Agents

A

a)Ticlopidine/Clopidogrel/ Praugrel: IRREVERSIBLY Block ADP receptors, inhibiting platelet aggregation

b)Aspirin: IRREVERSIBLY inhibits COX enxyme and thromboxane(potent activcator of platelet aggregation), leading to inhibition of platelets

c) Dipyridamole: REVERSIBLY increases plasma adenosine and inhibits platelet phosphodiesterase, causing inhibition of platelet activation and aggregation

Q

Notes on PK of aspirin

A

~18-25% decreased risk of having another stroke

  • inhibition of plt. aggregation require ~97% of COX-1 inhibition

*in ~70% of pts. this is achieved with an aspirin dose of 80-100 mg

*older age and obese patient may require higher doses of aspirin to produce effect

*inhibition of thromboxane occurs pre-systemically in portal circulation

*enteric coated products are erratically absorbed from the GI tract

Q

Dipyridamole ER vs. Aspirin

A

Dipyridamole ER (which has ~ same RRR as aspirin) not available in the US, only IR

ESPS2 study showed that inorder to achieve same time conc. of Dipyridamole ER with IR, pt must take IR 100 mg QID for the rest of their life, which would drastically increase risk of pt noncompliance.

Q

Aggrenox vs. Aspirin

A

Aggrenox is Dipyridamole ER+ASA combo

ESPS 2 study showed 36.8% RRR vs placebo and 23% RRR vs ASA.

HOWEVER, PROFESS study showed there is no difference btw. aggrenox and clopidogrel

Q

Overall, how to pick an antiplatelet agent best for the patient

A

Since there are no significant differences btw. anti-plt. choices, anti-plt agents used is based on whats best for individual patient.

A)base it on pt specific needs

consider..
side effect profile relative to your pts hx
(ex. Aggrenox can cause vascular headache, can cause GI problems->caution in GI problems..etc.)

the agent that produces an inhibition of aggregation in your specific patients (ex: some pts can be aspirin reisstant due to genetics)

can be used in lowest effective dose to reduce risk of bleeds

b) will aparticular agent be less than optimal for a particulr pt
*ex: ASA allergy
*pts on clopidogrel may have DDI w. agents that inhbit CYP2C19 such as CCBs, PPI’s etc.
*aggrenox therapy andmigraine hx
*aggrenox therapy and spastic colon or IBS

c)does your patient warrent dual anti-plt therapy
*Clopidogrel + ASA only has increased anti-plt effects in firt 30-90 days, then risk of bleeding outweighs beenfit
*coronary artery stenrs and new cerbral ischemia
*a. fib not able to take coumadin

d) are your pt plt. responding to their anti-plt agent
*ex: ASA or Plavix resistance

Q

Individualized pharmacotherapy for anti-plt. choice

A

urgency of needing full antiplt. therapy

agent least likely o produce adverse effects
*headache hx
*spastic coloitis or ulcerative colitis/chrons
*gastric ulcer hx
*true aspirin alergy

agent least likely for drug interactions
*need for chronic NSAID, PPI, or CCB use

dual anti-plt therapy
*failure of monotherpay
*first 3-6 mo post troke w. high risk factors

approach to plavix resistace
minimize use of other drugs that inhibit cyp3a4 AND CYP2C19 SUBSTITUTE DRUGS THAT HAVE LESSOR EFFECT ON THESE p450 is iso enzymes add meds that can induce CYP enzyme activity
26
common meds that influence CYP3A4 or CYP2C19
statins other than Rosuvastatin (crestor) CCBs, not BB, ACE, or ARBS *NOTE: IF CCB + clopidogrel is an issue in a pt, before switching the CCB, be sure pt is on CCB for htn and not rate control. if ccb used for rate control is changed, might do more harm in pt. Ambien, Lunesto (Sonata least likely) Gliburide, not glipizide or metformin Enablex, Ditropan, not detrol or sanctura PPI's
27
what to do if pt is truly resistant to both aspirin and clopidogrel
* ticagrelor *prasugrel BOTH OF THESE NOT FDA approved. *max ASA dose 100 mg daily w. ticagrelor

stress jet ag or shift work schedule change medical (chornic pain0 psychiatric (eg. anxiety, PTSD) pregnancy pharm. induced
33
causes of short term (<3 mo.) insomnia
untreated or undertreated transient insomnia acquired exacerbating behavior
34
common drrugs that can cause or worsen insomnia
alcohol, caffeine, nicotine anticholinergics SSRISNRIs alpha blockers beta blockers ACE and ARBS cholinesterase inhibitors bronchodilators CNS stimulants corticosterois decongestants diuretics H2RAs statins opioids
35
treatment goals for transient insomnia
orrect ynderlying sleep complaint, avoid AE of meds treatment: adequate bedtime doses of benzos for 2-3 weeks selection of specific med is patient dependent: *desirability for daytime anxiolytics *need fo rnext day early morningcognitive sharpness *interactions with other medications *d/c of problematic meds *pk profile of the BZDRA and specific insomnia complaints
36
tratment of short term insomnia goal
a treatment plan that will result in the pt sleeping normally w. no medications
37
non pharm treatment of insomnia
maintaine a regula sleep schedule establish a calm bedroom setting (quiet room, no bright lights, comfortable temp/) do not spend time in bed if awake imit intake of nicotine, caffeine, and alcohol exercise regulalrly but not close to bedtime have a light snack or warm bevarage befor ebedtime avoid watching the clock, remove bedroom clock if necessary
38
treatment oflongterm insomnia
proper dx of root/psychiatric cause of insomnia CBT for insomnia *preffered 1st line therapy for chronic insomnia in mos patients *CBT-I+/- meds> meds alone if rapid improvement is necessary, can use CBT-I_ meds initially w. plan to taper medication over time
39
Treatment options for insomnia BZDRAs
most commonly used trt. for insomnia fda approved for insomnia labels include a cuation for anaphylaxis, facial angioedema, and complex sleep behaviors agonist effects on gaba receptors includes newer non-benzo GABA agonists and traditional benzos always ake before bedtime use w. caution in elderly drowsiness, dizziness, confusion, risk of falls avoid w.alcohol withdrawal symptoms upon abrupt d/c i.e termors, muscle cramps, seizures
40
considerations for BZDRAs benzo hypnotics
CHOICE OF A PARTICULAR BZDRA IS BASED ON PK PROFILE AND PT. PRESENTATION reduce sleep larency increased stage 2 sleep and decrease delta sleep anxiolytic effect so not use in pts w. sleep apnea or substance abuse avoid alcohol and cns depressants side effects are dose dependent BBW: concaminant use with opioids can cause resp. depression,sedation, coma, and death *increased risk of abuse, misuse, and addiction *continued use can lead to clinically significant physical dependence
