An oral buccoadhesive drug delivery system for Losartan potassium using a hydrophilic polysaccharide, isolated from Prunus amygdalaus (Badam gum), was developed and evaluated for its potential to overcome the drawbacks associated with the conventional drug therapy. The results of the study indicate that the isolated polysaccharide has good physicochemical and morphological characteristics and is suitable for use as a mucoadhesive sustain release polymer in pharmaceutical dosage forms, to alleviate the drawbacks of the conventional drug therapy of Losartan potassium.

Background Introduction: Vestibular schwannoma (VS) tumors typically present with sensorineural hearing loss (SNHL). Losartan has recently demonstrated prevention of tumor-associated SNHL in a mouse model of VS through suppression of inflammatory and pro-fibrotic factors, and the current study investigates this association in humans.
Methods: This is a retrospective study of patients with unilateral VS and hypertension followed with sequential audiometry at a tertiary referral hospital from January 1994 to June 2023.

Losartan and other modulators of the Renin-Angiotensin System (RAS) have been used for their anti-fibrotic effects by non-surgeons for decades where suppression of maladaptive scar deposition is helpful, such as heart failure and chronic kidney disease. Only recently have orthopaedic surgeons begun to explore whether these medications might reduce or prevent post-operative joint stiffness. The relationship between orthopaedic surgeons and fibrosis is a more complicated.

We present a case of a 73-year-old woman with a medical history significant for hyperlipidemia, on pravastatin, who developed Takotsubo cardiomyopathy following a diagnosis of osteoporosis. She presented to the Emergency Department with acute transient left arm pain that resolved spontaneously. Investigations revealed elevated troponin levels, non-specific electrocardiographic changes, no significant coronary artery disease on angiography, and left ventricular systolic dysfunction, findings consistent with Takotsubo cardiomyopathy.

Objective: This research assesses renoprotective effects of saracatinib (Src) in diabetic nephropathy (DN) and the potential underlying processes.
Materials And Methods: Rats were divided into: control, DN, DN + Met + Los, DN + Met + Src, and DN + Met + Los + Src. Rats' ABP, urinary albumin, urinary nephrin, and creatinine clearance were assessed.

Background: Cardiovascular diseases constitute one of the leading causes of morbidity and mortality worldwide. Herbal medicines represent viable alternatives to the synthetic drugs currently employed in the control of hypertension. This study aimed to isolate and identify the chemical markers of and to investigate the antihypertensive and anti-matrix metalloproteinase (MMP2) activities of an aqueous extract of the leaves.
