THROMBOLYTICS OverviewStreptоkinаse; Alteplаse (Activаse); Reteplase (Retavase); Tenecteplase (TNKase) Mechanism оf ActiоnActivate plasminogen → plasminPlasmin degrades fibrin mesh → clot lysis → vessel reperfusionFibrin-specific agents bind fibrin-bound plasminogen → localized clot breakdownOlder clots are more resistant due to fibrin stabilization PharmacokineticsAlteplase, reteplase, tenecteplase: IV or catheter-directedHepatic metabolism (primarily)Urinary excretion of metabolitesShort onset (~30 min effect window for reperfusion activity)Tenecteplase and reteplase have longer half-lives → bolus dosing advantage PharmacodynamicsRapid fibrinolysis of formed thrombi (not prevention)High specificity agents limit systemic plasmin activationTherapeutic effect depends on clot age (early use most effective) IndicationsAcute myocardial infarction (MI)Acute ischemic stroke (time-sensitive)Venous thromboembolism (PE, selected DVT)Occluded catheters (dialysis, central lines)Adjunct in thrombosis management when anticoagulants insufficient aloneBest outcomes when given early (≤ ~6 hours from onset; stroke often narrower window clinically) Adverse EffectsCommon: Bleeding (most important and dose-limiting)Serious: Intracranial hemorrhageThromboembolism from clot fragmentationReperfusion injury (tissue damage after restoring flow) Contraindications & InteractionsAbsolute concern: any active bleedingRecent GI bleedIntracranial hemorrhage, tumor, aneurysmRecent intracranial/spinal/eye surgery or traumaHemorrhagic stroke historyAortic dissectionSevere uncontrolled hypertensionPregnancy (relative/clinical-risk dependent contexts) Question: A 72-year-old woman is brought to the emergency department 90 minutes after sudden onset of right-sided weakness and expressive aphasia. Non-contrast head CT shows no intracranial hemorrhage. Blood pressure is 168/92 mmHg. Past medical history is significant for an intracerebral hemorrhage 6 months ago. She is otherwise stable and is being evaluated for IV alteplase therapy. Which of the following is the most appropriate next step?
