Heparin

A

1) immediate anticoag for PE, ACS, MI, DVT (pregnancy safe)
2) Anti-thrombin: antithrombin cofactor –> decr thrombin* + decr factor Xa
3) toxicity: bleeding, HIT, osteoporosis, Rx interactions; protamine sulfate antidote (pos charge molec that binds neg charge heparin)
4) short 1/2 life

Enoxaparin

A

1) immediate anticoag for PE, ACS, MI, DVT (pregnancy safe)
2) LMWH antithrombin: act more on factor Xa
3) toxicity but less risk than heparin: bleeding, HIT, osteoporosis, Rx interactions; no antidote
4) compared to heparin: better bioavail, 2~4x longer 1/2 life; sub-Q; no need to monitor

Warfarin (Coumadin)

A

1) chronic anticoag: post STEMI, VTE prophylaxis, prevent stroke in afib (teratogenic)
2) antiplt: interfere w/ nl syn + carboyxlation of vit-K clotting factors (1972: X, IX, VII, II) + proteins C, S
3) bleeding, teratogenic, skin/tissue necrosis*, Rx interactions; give vit K for OD, give FFP for severe OD
4) cyt P450 met; incr PT (extrinsic path); long 1/2 life; follow PT/INR; PO

Q

Alteplase (tPA)

A

1) early MI, early ischemic stroke, direct thrombolysis of severe PE
2) thrombolytic: aid plasminogen –> plasmin to cleave thrombin + fibrin clots
3) bleeding (contraindicate in active bleed, intracranial bleed hx, recent sx, known bleed diathese, severe HTN); tx toxicity w/ aminocaproic acid (inhibits fibrinolysis)
4) incr PT, PTT; no change in plt ct

Q

Aspirin (ASA)

A

1) antipyretic, analgesic, anti-infl, anti-plt (decr aggregation)
2) irreversibly inhibits COX-1 (and -2) via covalent acetylation –> decr TxA2 + prostaglandins
3) gastric ulcer, tinnitus (CN VIII); chronic use: acute renal failure, interstitial nephritis, upper GI bleed; Reye’s syn in kids w/ viral infct; OD: respir alkalosis + met acidosis
4) plts can’t syn new COX so effect lasts until new plts made; incr bleeding time; no effect on PT, PTT
