final exam Flashcards
- Drug interactions w/ NSAIDs may block or reduce anti-HTN effect
- Not as good at preventing strokes as ACE-Is, ARBs, or CCBs
- Increase TGs and decrease HDL
- decreases renin and C.O.
beta blockers
- Clinical Use: HTN; anti-anginal
- MOA: selective beta-blocker
- AE: asthma, DM, cardiac depression
- Notes: give to a pt if they feel “worn out”
- *this term is used particularly with beta blockers that can show both agonism and antagonism at a given beta receptor
Acebutolol (ISA*), Atenolol, Metoprolol
- Clinical Use: HTN; anti-anginal
- MOA: non-selective beta-blocker
- AE: asthma, DM, cardiac depression
- Notes: mixed alpha AND beta blocker
Pindolol (ISA*), Labetalol, Propranolol
- Clinical Use: acute asthma
- MOA: selective beta-2-agonist
- AE: if given PO can cause tachycardia, nervousness, and tremors (“TNT”)
- Notes: use only if symptomatic; short-acting
Albuterol
- Clinical Use: acute asthma
- MOA: selective beta-2-agonist
- AE: tachycardia, nervousness, and tremors (“TNT”)
- Notes: use only if symptomatic; short-acting
Terbutaline
- Clinical Use: chronic asthma
- MOA: selective beta-2-agonist
- AE: unexplained deaths!!!; tachycardia, nervousness, tremors
Salmeterol, (Fomoterol)
• Properties
o Anti-inflammatory
• PGE2 and PGI2 cause erythema, incr blood flow
• Incr vascular permeability a/w other inflam mediators
o Analgesia
• PG’s cause hyperalgesia
o Antipyretic
• Pyrogens/cytokines incr endogenous hypothalamic formation of PGE2 which elevates body temp =incr in heat generation and DECR heat loss
• SE’s:
o gastric and intestinal ulceration–>mild dyspepsia and heartburn; may be accompanied by anemia from blood loss; local irritatin from drug PLS removal of PGE2 and PGI2
o inhibition of platelet fxn/CV risk–>NSAIDs inhibit platelet fxn which promote “stickiness” and clumping
o renal toxicity–>decr renal blood flow and GFR in pts with CHF; promote salt and H2O retention by PG-induced inhibition of both reabsorption of Cl- and action of ADH
o ASA intolerance–>pts may develop nasal polyps, asthma, chronic urticaria
o prolongation of gestation–>PG’s are uteotropic agents=their biosynthesis by the uterus incr dramatically in the hours before parturition; may provoke premature closure of ductus arteriosus
NSAIDs
- Clincal Use: Low doses=inhibit platelet function; moderate doses=provide analgesia and antipyresis; large doses=full anti-inflammatory and anti-rheumatoid effects
- MOA: irreversibly acetylates (blocks) COX-1 and COX-2=permanently inactivating
- AE: gastric irritation, ulceration, erosion, hemorrhage; incr bleeding time; decr renal fxn in pts at risk; hepatic injury (at large doses)
aspirin
- Clinical Use: adjunctive therapy for PD w/ L-DOPA
- MOA: D2 receptor agonist and D1 receptor ANTagonist
- AE: drug-induced tardive dyskinesia; NV; Orthostatic hypoTN and cardiac arrhythmias
- CI: females who are breast feeding or pregnant
- Notes: LOW GI absorption; only works in pts responsive to L-DOPA
Bromocriptine
- Clinical Use: PD; adjunctive therapy when L-DOPA effects decline
- MOA: inhibits DA catabolism (MAO-B irreversible inhibitor); enhances DA to brain
- AE: Hypertensive episodes
- CI: tricyclic antidepressants and SSRIs (i.e., Prozac)
- Notes: Good GI absorption; reaches CNS quickly; t1/2=1.5h; improves cognitive fxns a/w PD (early stages)
Selegiline
- Clinical Use: anti-epileptic (anticonvulsant)
- MOA: inactivation of Na+ channels=decr excitability
- AE: dizziness diplopia, nystagmus, blurred vision, ataxia, vertigo, N, confusion; H2O retention
- Notes: CYP3A4 induction
carbamazepine
- Clinical Use: anti-epileptic (anticonvulsant)
- MOA: inactivation of Na+ channels=decr excitability
- AE: dizziness, blurred vision, HA, ataxia; 10% of pts may get a rash that can evolve into Steven-Johnson Syndrome
lamotrigine
- Clinical Use: anti-epileptic (anticonvulsant)
- MOA: increases GABA effects
- AE: sedation, GI upset, diarrhea, tremor, ataxia, platelet dysfxn; hepatotoxicity, weight gain; hair loss; spina bifida (teratogenicity)
- Notes: drug of choice for MOST seizures
valproate
- Clinical Use: anti-epileptic (anticonvulsant); EtOH dependence; migraines
- MOA: blocks Na+ channels; augments GABA activity; antagonizes glutamate receptors; inhibits carbonic anhydrase
- AE: CNS effects, weight loss, kidney stones, metabolic acidosis
topiramate
- Clinical Use: as stated above
- MOA: binds BZD receptor, enhancing GABA effects
- AE: sedation, dizziness, ataxia, fatigue, confusion, diplopia
- Notes: intermediate t1/2; overdose is reversed by Flumazenil
clonazepam
- Clinical Use: anti-epileptic (status epilepticus)
- MOA: binds BZD receptor, enhancing GABA effects
- AE: sedation, dizziness, ataxia, fatigue, confusion, diplopia
- Notes: intermediate t1/2; overdose is reversed by Flumazenil
diazepam
