what is ticlopidine used for

Ticlopidine is a medication that falls under the class of platelet aggregation inhibitors. It is primarily used to prevent platelets from clumping together, which can lead to the formation of blood clots. By inhibiting platelet aggregation, it helps to reduce the risk of thrombotic events, such as heart attacks or stroke, in at-risk patients.

Mechanism of Action:

It works by selectively inhibiting the ADP-induced aggregation of platelets. ADP (adenosine diphosphate) is one of the chemicals in the body that helps activate platelets, causing them to clump together. By blocking this action, this medicine helps to maintain the fluidity of blood and prevent the formation of clots that can block blood vessels.


  • Stroke Prevention: Ticlopidine is used to reduce the risk of stroke in patients who have had a transient ischemic attack (TIA) or a stroke due to a blood clot.
  • Coronary Syndrome: It can be used to reduce the risk of heart attack or death in patients with unstable angina (chest pain) or a history of heart attack.

Side Effects:

Ticlopidine may cause several side effects, including gastrointestinal discomfort, diarrhea, rash, nausea, and headache. It can also potentially lead to more serious conditions such as neutropenia (a decrease in white blood cells), thrombocytopenia (a decrease in platelet count), and agranulocytosis (a severe decrease in white blood cells). Regular blood monitoring is often required to check for these conditions.

Here are some of the potential side effects of ticlopidine along with suggested management strategies:

  1. Gastrointestinal Discomfort: This can include symptoms such as abdominal pain, diarrhea, and nausea. To manage these symptoms, it may help to take ticlopidine with food or to divide the dose into smaller, more frequent doses. If symptoms persist or worsen, a healthcare provider may recommend a medication to reduce stomach acid or an antidiarrheal agent.
  2. Rash: Skin rash is a common side effect that can range from mild to severe. For mild rashes, over-the-counter hydrocortisone cream may provide relief. If the rash is more severe or accompanied by fever, itching, or blistering, it could be a sign of a serious allergic reaction, and ticlopidine should be discontinued immediately. A healthcare provider should be notified, and alternative treatment options may be considered.
  3. Headache: Mild headaches can often be managed with over-the-counter pain relievers such as acetaminophen. However, if the headaches are severe or persistent, a healthcare provider should be consulted to rule out other causes and to discuss potential adjustments to the treatment regimen.
  4. Neutropenia: This is a decrease in the number of neutrophils, a type of white blood cell that helps fight off infections. Regular blood monitoring is essential to detect neutropenia early. If detected, ticlopidine may be discontinued, and the patient should be closely monitored for signs of infection. In some cases, treatment with granulocyte colony-stimulating factor (G-CSF) may be necessary to stimulate the production of white blood cells.
  5. Thrombocytopenia: This condition is characterized by a low platelet count, which can increase the risk of bleeding. Regular blood tests can help detect thrombocytopenia. If it occurs, ticlopidine may be discontinued, and the patient may require treatment to increase platelet counts or management of any bleeding complications.
  6. Agranulocytosis: This is a potentially life-threatening condition characterized by a severe decrease in white blood cells, including neutrophils and other types of granulocytes. If agranulocytosis is suspected, ticlopidine should be stopped immediately, and the patient should be hospitalized for close monitoring and treatment, which may include antibiotics to prevent or treat infections.
  7. Increased Risk of Bleeding: Ticlopidine can increase the risk of bleeding, including gastrointestinal bleeding. Patients should be instructed to report any unusual bleeding or bruising to their healthcare provider. If bleeding occurs, ticlopidine may need to be discontinued, and the patient may require treatment to manage the bleeding.


Patients with a known hypersensitivity to this medicine or any of its components should not take this medication. It should also be used with caution in patients with a history of bleeding disorders or those who are taking other medications that can increase the risk of bleeding.


this medicine can interact with other medications, including warfarin, aspirin, and other antiplatelet drugs, which can increase the risk of bleeding. It may also interact with certain medications that are metabolized by the liver enzymes CYP2C19 and CYP3A4.


The typical dosage is 250 mg to 500 mg daily, taken with or without food. It’s important for patients to follow the prescribing physician’s instructions exactly.


Due to the potential for serious side effects, patients taking ticlopidine often require regular blood tests to monitor their blood cell counts and liver function.


Ticlopidine should be used with caution in elderly patients and those with hepatic (liver) or renal (kidney) impairment. It should be discontinued prior to surgery or any invasive procedures due to the increased risk of bleeding.
