From the Guidelines

Ranolazine (Ranexa) is not commonly associated with thrombocytopenia, and there is no strong evidence to suggest a significant risk of this side effect. The provided evidence does not mention thrombocytopenia as a potential side effect of ranolazine 1. According to the expert consensus document, ranolazine has a good safety profile, being devoid of any adverse haemodynamic effects when used as monotherapy or in combination 1. Some key points to consider when prescribing ranolazine include:

  • Monitoring complete blood counts in patients on ranolazine, especially those with pre-existing hematological disorders or those taking other medications that might affect platelet counts.
  • Being aware of the potential for rare side effects, although thrombocytopenia is not specifically mentioned in the provided evidence.
  • Considering alternative treatments if patients experience unusual bruising, bleeding gums, nosebleeds, or prolonged bleeding from cuts while taking ranolazine. It is essential to prioritize the patient's overall health and well-being, considering the potential benefits and risks of ranolazine treatment, as well as alternative options 1. Healthcare providers should weigh the benefits of ranolazine against potential risks and consider individual patient factors when making treatment decisions 1.

From the FDA Drug Label

Other (<0. 5%) but potentially medically important adverse reactions observed more frequently with Ranolazine Extended-Release Tablets than placebo treatment in all controlled studies included: ... thrombocytopenia, leukopenia, and pancytopenia

  • Thrombocytopenia is listed as a potentially medically important adverse reaction that occurred at an incidence of less than 0.5% in patients treated with Ranolazine Extended-Release Tablets.
  • The FDA drug label directly supports the answer that Ranexa (ranolazine) can cause thrombocytopenia, although it is a rare occurrence 2.

From the Research

Ranexa and Thrombocytopenia

  • There is no direct evidence in the provided studies that suggests Ranexa (ranolazine) can cause thrombocytopenia 3, 4, 5, 6, 7.
  • The studies primarily focus on the use of ranolazine in the treatment of chronic stable angina, its mechanism of action, and its effects on heart rate and blood pressure.
  • None of the studies mention thrombocytopenia as a potential side effect of ranolazine.
  • The provided evidence highlights the drug's efficacy and tolerability in patients with chronic stable angina, but does not address the specific question of thrombocytopenia 3, 4, 5, 6, 7.

Available Information

  • The studies discuss the pharmacokinetics, proposed mechanism of action, and clinical trials evidence for ranolazine 3, 4, 5, 6, 7.
  • They also outline the indications for its use in chronic stable angina and its potential benefits in patients with comorbidities 5, 6, 7.
  • However, there is no information available in the provided studies that directly addresses the question of whether Ranexa can cause thrombocytopenia.
