No. It is an enzyme (a thrombolytic) derived from bacteria, but its function is to dissolve clots, not kill bacteria.

Historically, it was chosen due to its significantly lower cost compared to newer genetically engineered agents like alteplase, though it may have a different side-effect profile.

It is generally used only once in a patient's lifetime because the body can develop antibodies against it, reducing its effectiveness and increasing the risk of allergic reactions upon subsequent use.
