In this episode, we will discuss the definition of REMS (Risk Evaluation and Mitigation Strategies), why they exist, the role of FDA in administering REMS, types and examples of REMS, and how they impact pharmacy practice.

Key Concepts

1. The REMS (Risk Evaluation and Mitigation Strategies) program was developed in 2007 as part of the FDA’s drug risk management strategies designed to balance risk and benefits of certain drugs.
2. Elements of REMS vary depending on the drug, but commonly include medication guides, communication plans, and other elements to assure safe use.
3. REMS can require patients, providers, and pharmacies to take certain actions including training, registration, enrollment, safety monitoring, documentation of safety concerns, and follow prescribing and dispensing regulations. 
4. The FDA captures and assesses data on a regular basis to make changes in the REMS program. It also has authority to enforce compliance and take punitive actions against non-compliant parties.

In this episode, we review the role and indications of thrombolytics in acute ischemic stroke. The efficacy, safety, administration considerations, and cost between alteplase and tenecteplase are compared and contrasted.

Key Concepts

1. Alteplase (Activase) is a recombinant DNA version of human TPA (tissue plasminogen activator). Tenecteplase (TNKase) is similar to human TPA except it has three amino acid changes that result in a longer half-life and higher fibrin specificity.
2. In patients with stroke, alteplase is given as a bolus followed by a 60-minute infusion. Tenecteplase is given as an IV bolus without the need for an infusion due to its longer half-life.
3. Tenecteplase is at least as safe and effective as alteplase in acute ischemic stroke (with some studies showing greater benefit with tenecteplase).
4. In patients with acute ischemic stroke who are candidates for mechanical thrombectomy, thrombolytics (with alteplase or tenecteplase) will still be given in patients who meet inclusion criteria and have no exclusion criteria.
