Thrombolytic Agents Information - Drug Interactions

Blood clot dissolvers

How the Drug Works:

Thrombolytic agents dissolve blood clots and restore blood circulation to affected body tissue.

Uses:

To dissolve blood clots, including those blocking coronary arteries in acute heart attacks.

Precautions:

Alteplase: To help manage acute ischemic strokes in adults to reduce the chances of disability, or to reduce the incidence of congestive heart failure (CHF) and death due to heart attack.

Streptokinase: To dissolve large blood clots in legs.

Unlabeled Uses: Occasionally doctors may prescribe alteplase for the treatment of unstable angina pectoris (chest pain).

Abnormal heartbeats: Use of thrombolytic agents to dissolve clots in coronary arteries (acute heart attack) may result in abnormal heartbeat. Heart rate will need to be monitored during and following therapy.

Pregnancy: Safety for use during pregnancy has not been established.

Use only if clearly needed and the potential benefits to the mother out­weigh the possible hazards to the fetus.

Breastfeeding: It is not known if thrombolytic agents appear in breast milk. Consult your doctor before you begin breastfeeding.

Children: Safety and effectiveness have not been established.

Lab Tests: Lab tests will be required to monitor therapy. Tests may include platelet counts, thrombin time (TT), activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen levels, hematocrit counts, as well as the monitoring of blood pressure, heart rate and rhythm, and other vital signs (eg, respirations, temperature).

Drug Interactions:

Tell your doctor or pharmacist if you are taking or will be taking any over­the-counter or prescription medications or dietary supplements while taking a thrombolytic agent. Doses of one or both drugs may need to be modified or a different drug may need to be prescribed. The following drugs and drug classes interact with thrombolytic agents:

  • Anticoagulants (eg, warfarin)
  • Aspirin antiplatelet agents heparin (eg, Hep-Lock)
  • Ndomethacin (eg, Indocin)

Bleeding: Bleeding at puncture and incision sites; bleeding from rectum, stomach, lungs, gums, mouth, nose, or urinary tract.

Digestive Tract: Nausea; vomiting.

Circulatory System: Internal bleeding; irregular heartbeat; changes in blood pressure.
