What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing if Losartan, a blood pressure medication, can help reduce scar tissue and stiffness in patients after knee replacement surgery. It aims to improve movement and reduce the need for additional surgeries. Losartan has been studied for various effects including reducing blood pressure and improving heart function.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are already taking an ACE-inhibitor or Angiotensin receptor blocker for hypertension, you cannot participate in this study.

Is losartan generally safe for humans?

Losartan, also known as Cozaar or Hyzaar, is generally well tolerated in humans and has been used safely for conditions like high blood pressure and heart failure. It has a low incidence of side effects, with some studies showing it is better tolerated than other similar medications.12345

How is the drug Losartan unique for treating arthrofibrosis?

Losartan is unique for treating arthrofibrosis because it is primarily known as a medication for high blood pressure and heart-related conditions, and its use for arthrofibrosis is novel, as there are no standard treatments specifically for this condition.678910

Published Research Related to This Trial

Losartan, a medication for hypertension, was well-tolerated in approximately 2000 patients, showing a lower incidence of adverse effects compared to other antihypertensive drugs, particularly ACE inhibitors.
The most common side effects reported with losartan were headache and dizziness, but overall, it had a better safety profile with only 2.3% of patients withdrawing due to adverse effects, and no significant safety concerns were noted across different demographic groups.

Losartan/hydrochlorothiazide (HCTZ) is an effective fixed-dose combination therapy for hypertension, providing greater blood pressure reduction than either medication alone, and is particularly beneficial for patients with severe hypertension and left ventricular hypertrophy (LVH).
In the LIFE study, losartan-based therapy demonstrated a lower incidence of cardiovascular events and new-onset diabetes compared to atenolol, highlighting its safety and efficacy in reducing stroke risk and improving overall cardiovascular health.

Losartan potassium, an angiotensin II receptor antagonist, shows significant haemodynamic benefits in patients with heart failure, based on extensive clinical trials.
The drug is well tolerated with a low incidence of adverse effects related to kidney function, making it a safe option for treating hypertension and heart failure.
