Original Abstract of the Article

Key Research Findings

Hyaluronidase is used in subcutaneous formulations (e.g. RITUXAN HYCELA, HERCEPTIN HYLECTA, PHESGO, Darzalex FASPRO) to increase the dispersion and absorption of coadministered therapeutics. 2 investigated the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of recombinant human hyaluronidase PH20 (rHuPH20) administered intravenously. The study was conducted to understand the potential effects of inadvertent intravenous injection of rHuPH20.

Another study compared the long-term efficacy of torsemide and frusemide in cirrhotic patients with ascites. 1 aimed to compare the efficacy and safety of torsemide versus frusemide in cirrhotic patients with uncomplicated ascites.

Benefits and Risks

Benefits Summary

Hyaluronidase is an effective way to enhance drug absorption and is used in various formulations. 2 Torsemide was found to be more effective than frusemide in diuretic effect in cirrhotic patients with ascites. 1

Risk Summary

The safety of intravenous injection of rHuPH20 was confirmed. 2 Torsemide may have a higher risk of side effects compared to frusemide. 1

Comparison of Studies

Similarities

Both studies evaluated the effects and safety of a specific drug. 2 and 1

Differences

The hyaluronidase study aimed to evaluate the safety of its intravenous injection, while the torsemide study aimed to evaluate its long-term efficacy in cirrhotic patients. 2 and 1

Consistency and Contradictions of Results

Both studies demonstrated the efficacy of a specific drug in specific situations. 2 and 1 However, the torsemide study suggested that it might have a higher risk of side effects. 1

Implications for Daily Life

Hyaluronidase can be safely used subcutaneously to enhance drug absorption. 2 Torsemide may be a more potent diuretic for cirrhotic patients with ascites. 1 However, it's crucial to use torsemide under medical guidance due to its potential for side effects. 1

Limitations of Current Research

The hyaluronidase study was conducted on a small number of healthy volunteers. 2 The torsemide study was conducted on only a specific type of cirrhotic patients. 1

Future Research Directions

Larger-scale studies are needed to evaluate the long-term effects and safety of hyaluronidase. 2 More research is also necessary to further investigate the side effects of torsemide. 1

Conclusion

Hyaluronidase is an effective way to enhance drug absorption and is used in various formulations. 2 Torsemide may be a more potent diuretic for cirrhotic patients with ascites. 1 These medications can improve patient health when used safely.

Long-term efficacy of torsemide compared with frusemide in cirrhotic patients with ascites.

Author: AbecasisR, GuevaraM, MiguezC, CobasS, TergR

Diuretic action
Natriuretic action
Long-term effects unknown

Torsemide is a new loop diuretic that has shown, in short-term studies, to induce a longer and higher diuretic and natriuretic action than frusemide. However, torsemide long-term effects and complications have not been sufficiently investigated. The aim was to compare the efficacy and safety of torsemide versus frusemide in cirrhotic patients with uncomplicated ascites.

Clinical TrialA clinical trial is a planned study conducted on humans to evaluate the efficacy and safety of pharmaceuticals, medical devices, and treatment methods. It aims to explore the possibilities of new treatments and improve the health of patients.
Comparative StudyResearch that compares multiple groups/interventions to determine differences/similarities in outcomes/characteristics.
Journal ArticleAn article published in an academic or professional journal that reports original research or scholarly analysis.
Randomized Controlled TrialA clinical trial that randomly assigns participants to treatment and control groups to evaluate the effects of an intervention.
