What is the half-life of Cathflo?
Alteplase is cleared rapidly from the circulating blood and metabolised mainly by the liver (plasma clearance 550 – 680 ml/min.). The relevant plasma half-life t1/2 alpha is 4-5 minutes.
How long is Cathflo active?
Secondary objectives included assessing success rates at 30 minutes and 120 minutes. In COOL-1, Cathflo restored function to 88% (112/127) of central lines after up to 2 doses using a 120-minute dwell time for each in catheters with occlusions present for up to 24 hours.
Can you flush Cathflo?
If catheter function has been restored, ASPIRATE 4 to 5 mL of blood in patients ≥10 kg or 3 mL in patients <10 kg to remove Cathflo and residual clot. Then discard aspirate and flush the catheter with 0.9% Sodium Chloride, USP. Any unused solution should be discarded.
How long is alteplase stable?
Conclusions: Alteplase diluted in normal saline solution at a concentration of 0.01 mg/mL is biochemically stable and active at ambient temperature for as long as 24 hours as assessed by in vitro clot lysis assays.
How long does Cathflo last in refrigerator?
The solution may be used within 8 hours if stored at 2°C to 30°C (36°F-86°F).
Can you flush alteplase?
Use a push-pause (pulsing) method to flush. If you can’t aspirate blood after waiting 30 minutes, wait until 2 hours have elapsed, then try again. If you still can’t obtain a blood return, instill a second dose of alteplase and repeat the process.
Can you leave Cathflo in overnight?
Cathflo has proven efficacy. In COOL-1, Cathflo restored function to 88% (112/127) of central lines after up to 2 doses using a 120-minute dwell time for each in catheters with occlusions present for up to 24 hours.
Does Cathflo need to be refrigerated?
Lyophilized Cathflo should be stored at refrigerated temperatures (2°C-8°C/36°F-46°F). Cathflo should be reconstituted immediately before use.

How long can tPA go unrefrigerated?
Currently, tPA is available as a lyophilized powder from the manufacturer (Genentech, San Francisco, CA). According to the manufacturer, tPA can be used for 8 hours after reconstitution in sterile water at room temperature; this is a short period of time for laboratory use.
How do you reconstitute Cathflo?
Cathflo is available for reconstitution in a single-use 2-mg vial. 8
- Aseptically WITHDRAW 2.2 mL of Sterile Water for Injection, USP (diluent is not provided).
- INJECT the 2.2 mL of Sterile Water for Injection, USP, into the Cathflo vial, directing the diluent stream into the powder.
What is the medicine half life calculator used for?
The medicine half life calculator can be used to follow the plasmatic concentration decrease (in percentage) for any substance, when dosage and half time are input. Half life estimation is especially useful when trying to keep constant levels of medicine in the body or when trying to avoid pharmacological interactions between substances. After…
What is half life in chemistry?
