Thrombolytics — Thrombolytic (clot buster); Tissue plasminogen activators.

Identification

• Therapeutic class: Thrombolytic (clot buster).
• Pharmacologic class: Tissue plasminogen activators.

Pharmacology

• Mechanism of action: Convert plasminogen to plasmin to dissolve existing clots.
• Onset / peak / duration: Acts within minutes; short window of administration.
• Half-life / therapeutic level: Very short; no routine level.

Clinical use

• Indications: Acute ischemic stroke (within the time window), acute myocardial infarction, massive pulmonary embolism, occluded catheters (low dose).
• Usual dose, route, frequency: IV by protocol and weight; strict time windows.
• Maximum dose / adjustments: Per protocol; absolute time limits for stroke.

Safety

• Contraindications: Active internal bleeding, recent stroke or surgery or major trauma, intracranial hemorrhage or neoplasm, severe uncontrolled hypertension, bleeding disorders.
• Black box warning: None formal; bleeding, including intracranial hemorrhage, is the major risk and screening for contraindications is critical.
• Interactions: Anticoagulants and antiplatelets (bleeding).
• Pregnancy / lactation: Use only in life-threatening situations.
• High-alert: Yes.

Adverse effects

• Common side effects: Bleeding at puncture sites, hypotension.
• Serious effects to report: Intracranial hemorrhage (sudden severe headache, neuro changes), major bleeding, allergic reaction.
• Antidote / reversal: Stop the infusion; supportive care and blood products.

Nursing process

• Assessment before administration: Strict contraindication screening, time of symptom onset, blood pressure, baseline labs and neuro exam.
• Interventions during therapy: Minimize punctures and invasive procedures; control blood pressure; frequent neuro checks; have blood products available.
• Monitor: Neuro status, blood pressure, bleeding, vital signs frequently.
• Evaluation / expected outcome: Clot dissolution and restored perfusion.

Patient teaching

• Patient teaching: Emergency therapy; report any bleeding or sudden symptoms.
• Notify provider if: Sudden severe headache, weakness, any bleeding (emergency setting).
• Administration tips: Time-critical; thorough contraindication screening; high-alert.
