When was tpa approved by fda

There followed considerable public debate in which we were accused of "deciding to sacrifice thousands of American lives on an altar of pedantry" The Wall Street Journal , June 2, In essence, many observers opined that we had elected to debate picayune, unsolvable issues rather than make an important and lifesaving therapy available to the American public. In response to one of the editorials in the lay press, we attempted to explain the issues.

October 21, Activase is a tissue plasminogen activator that FDA approved in for use in the management of acute myocardial infarction and later approved it for acute ischemic stroke and pulmonary embolism indications.

TNKase, also a tissue plasminogen activator, was FDA approved in for the management of acute myocardial infarction only. Since the initial reports, we continue to receive cases of confusion between these two products. In , a patient who experienced an ischemic stroke received TNKase instead of the intended Activase.

Wrong drug errors between TNKase and Activase can be attributed to the fact that both have similar settings of use emergency departments, critical care areas and patient populations cardiac events. The consequences of giving patients with ischemic stroke TNKase instead of Activase include the failure to administer a drug of known effectiveness Activase and the potential for overdose—the dose for Activase 0.

An overdose of TNKase may increase the risk of intracranial hemorrhage, retroperitoneal bleed, extended hospitalization, and death. Therefore, we recommend the following:. Recent experience suggests that under some circumstances, with careful consideration and weighing of risk to benefit, patients may receive fibrinolytic therapy despite 1 or more relative contraindications.

Consider the risk to the benefit of intravenous rtPA administration carefully if any of these relative contraindications are present:. There are no therapeutic drug monitoring recommendations that pertain to the efficacy of tPA therapy. If prolonged off-label therapy is occurring in the event of catheter-directed treatment or repeated dosing in valve thrombosis, serial imaging of the thrombus is reasonable.

The safety profile is best monitored by prothrombin time PT , partial thromboplastin time PTT , Hemoglobin, and hematocrit to assess ongoing bleeding. There is no direct reversal agent for the potentially major bleeding that may occur during tPA therapy. Commonly employed strategies include anti-fibrinolytic therapy such as tranexamic acid or aminocaproic acid though there is no research on specific dosages.

Cryoprecipitate should be used without any delay and monitor the fibrinogen level closely. There is no longer any question about the effectiveness of thrombolytic agents for the treatment of several medical disorders, but nurses, pharmacists, and radiologists must be fully aware of their indications and contraindications. For these agents to be effective, not only do they require administration within a certain timeframe, but one also has to ensure that the patient has no condition that contraindicates the therapy.

Also, the nurse should educate the patient about the procedure, the need to remain at bed rest for several hours after the procedure, and the need to constantly monitor for bleeding. Plus, the pharmacist must be familiar with the recent novel anticoagulants and any possible interactions with the thrombolytic drugs. Only through close communication and constant vigilance between the various healthcare professionals can the serious complications of these drugs be prevented.

There have been many clinical trials undertaken to determine the effectiveness of thrombolytic agents in patients with acute myocardial infarction, pulmonary embolism, acutely ischemic limb, and an embolic stroke. When used to treat acute MI, embolic stroke, and pulmonary embolism, the outcomes are fair to good.

The biggest drawback to this therapy is a patient delay in arriving at the emergency room or a delay in diagnosis. These drugs have saved many lives and are cost-effective and reduce hospital stays.
