The invention belongs to the technical field of biological medicine, and particularly provides application of flufenidone in preparation of a medicine for preventing or treating left heart failure. The research finds that the flufenidone has the effects of relieving myocardial cell hypertrophy under a heart failure cell model and relieving myocardial hypertrophy, fibrosis and heart function deterioration of an aortic constriction animal model. According to the present invention, further research results show that fluorofenidone is directly combined with SERCA2a through Q758, D812 and E917 residues of SERCA2a so as to inhibit recognition, combination and polyubiquitination effects of WWP1 on SERCA2a, such that the protein level and the activity of SERCA2a are stabilized so as to achieve the chronic left heart failure treatment purpose. Therefore, the flufenidone serving as an active ingredient has good application prospect and application value in research and development of novel medicines for treating chronic left heart failure.

A pharmaceutical composition and a method of administering the pharmaceutical composition to a patient suffering from edema, heart failure, kidney or liver disease or having symptoms thereof is disclosed. The pharmaceutical composition includes furosemide, or a pharmaceutically acceptable salt, hydrate or ester thereof and tris(hydroxymethyl)aminomethane. The furosemide is present in the pharmaceutical composition at a concentration from about 10 mg / mL to about 30 mg / mL and the tris(hydroxymethyl)aminomethane is present at a concentration of less than or equal to 40 mM. The pH value of the pharmaceutical composition is maintained between about 8.0 and about 8.5 for parenteral administration.

A heart failure management system for a patient includes a plurality of sensors including at least one implantable pressure sensor positioned within the heart to capture synchronized left and right heart pressure waveforms, transmitted via one or more transmitters to a receiver. Control circuitry receives these waveforms and processes them using a machine learning medication dosage management model, trained on historical left and right heart pressure logs, volume status metrics (e.g., weight, fluid intake, symptoms), and / or ground truth dosage logs for certain heart failure treatment medications, such as a blood pressure reducing medication (e.g., ARNI) and an intravascular volume reducing medication (e.g., Lasix). The model can generate real-time dosage recommendations, systemic blood pressure, and volume load predictions in real-time, enabling precise, data-driven treatment adjustments aligned with clinical guidelines, supporting timely clinical decisions or automated medication dispensing to optimize patient outcomes and reduce hospitalization risks.

Materials and methods for treating hypertension (including resistant hypertension) with a combination of an M-atrial natriuretic peptide (MANP) and a diuretic agent (e.g., furosemide) are described herein.

This invention discloses a production process and purification method for furosemide, comprising the following steps: S1, adding crude furosemide to an inorganic alkaline solution, allowing it to react fully, decolorizing and filtering, adjusting the pH of the filtrate to acidic conditions with acid to induce crystallization, filtering and washing to obtain a solid substance; S2, adding the solid substance to a recrystallization solvent, heating and refluxing it at boiling point until the solution temperature remains constant, filtering while hot, transferring the filtrate to a crystallization vessel, heating the solution to its boiling point and then stopping heating, setting the pressure of the crystallization vessel to 3-60 kPa to induce crystallization, and extracting the evaporated solvent. After the solution in the crystallization vessel stops boiling, cooling the solution to 10-15°C using circulating cooling water to continue crystallization, filtering, washing, and drying to obtain the finished furosemide product. The purification method of this invention can avoid cold wall precipitation of crystals, reduce waste liquid generation, and significantly improve the purity and yield of furosemide.
