Rezdiffra

Rezdiffra (resmetirom) is the first and only FDA-approved medication specifically for adults with nonalcoholic steatohepatitis (NASH) accompanied by moderate to advanced liver fibrosis, but without cirrhosis. Rezdiffra NASH, a severe form of nonalcoholic fatty liver disease (NAFLD), involves liver inflammation and damage due to fat accumulation, potentially leading to significant scarring (fibrosis) and liver dysfunction. This condition is often associated with metabolic disorders such as obesity, type 2 diabetes, and high cholesterol. ​Verywell Health+2Rezdiffra™ (resmetirom) Patient Website+2U.S. Food and Drug Administration+2U.S. Food and Drug AdministrationVerywell Health

Mechanism of Action: Rezdiffra functions as a selective thyroid hormone receptor-beta (THR-β) agonist. By activating these receptors in the liver, it enhances the metabolism of lipids, thereby reducing hepatic fat accumulation. This action addresses the underlying causes of NASH, aiming to decrease liver inflammation and fibrosis progression. ​Rezdiffra™ (resmetirom) Patient Website

Clinical Efficacy: In clinical trials, Rezdiffra demonstrated significant benefits. After 12 months of treatment, a higher percentage of patients achieved NASH resolution without worsening fibrosis compared to those on placebo. Additionally, more patients experienced an improvement in liver fibrosis without NASH progression. These results highlight Rezdiffra’s potential to alter the disease course favorably.Rezdiffra ​Reuters+4U.S. Food and Drug Administration+4Verywell Health+4

Availability in the UK: As of April 2025, Rezdiffra has received FDA approval in the United States. However, its approval status in the United Kingdom remains uncertain. Medications approved by the FDA require separate authorization from the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) before they can be legally marketed and prescribed in the UK. Therefore, it’s essential to verify whether Rezdiffra has obtained MHRA approval.​Reuters+3Rezdiffra™ (resmetirom) Patient Website+3U.S. Food and Drug Administration+3

Purchasing from UKHealth4Life.com: UKHealth4Life.com lists Rezdiffra among its products, offering it in various quantities. However, the website lacks detailed information about the product, including dosage forms, strengths, and manufacturer details. Additionally, the absence of comprehensive contact information and regulatory compliance indicators raises concerns about the legitimacy and safety of purchasing medications from this source.
