Drug repurposing is a promising strategy for managing cardiovascular disease (CVD) in geriatric populations, offering efficient and cost-effective solutions. CVDs are prevalent across all age groups, with a significant increase in prevalence among geriatric populations. The middle-age period (40-65 years) is critical due to factors like obesity, sedentary lifestyle, and psychosocial stress.

Effect of long and short half-life PDE5 inhibitors on HbA1c levels: a systematic review and meta-analysis.

EClinicalMedicine

February 2025

Human Stem Cell and Genome Engineering Center, University of California Los Angeles David Geffen School of Medicine, UCLA - CHS 36 - 125/133/143 650 Charles E. Young Dr. South, Los Angeles, CA, 90095, USA.

Background: Phosphodiesterase 5 (PDE5) inhibitors, owing to their mechanism of action, have been gaining recognition as a potential case of drug repurposing and combination therapy for diabetes treatment. We aimed to examine the effect of long and short half-life PDE5 inhibitors have on Haemoglobin A1c (HbA1c) levels.

Methods: A systematic review and meta-analysis was conducted of randomised controlled trials (RCTs) in people with elevated HbA1c (>6%) to assess mean difference in HbA1c levels from baseline versus controls after any PDE5 inhibitor intervention of ≥4 weeks, excluding multiple interventions.

Acquired Dyschromatopsia and Its Link to Drug Toxicity.

Cureus

December 2024

Optometric - Glaucoma, Leicester Royal Infirmary, Leicester, GBR.

Colour vision defects (CVDs) can be both congenital and acquired, with acquired dyschromatopsia often associated with medication toxicity. This review explores various standardised colour vision tests used to detect these defects, including the Ishihara plate test, Farnsworth-Munsell 100 hue test, and anomaloscopes. These methods are evaluated for their effectiveness in diagnosing CVDs, particularly in acquired conditions.

Rationale: Chylothorax is a rare adverse effect that is associated with dasatinib, a tyrosine kinase inhibitor administered for chronic myeloid leukemia (CML) treatment. Most reported cases have described standard dosing. In this case report, we described a 43-year-old male patient with CML who developed chylothorax after 4 years of low-dose dasatinib therapy.

Repurposing of phosphodiesterase-5 inhibitor sildenafil as a therapeutic agent to prevent gastric cancer growth through suppressing c-MYC stability for IL-6 transcription.

Commun Biol

January 2025

Department of General Surgery & Guangdong Provincial Key Laboratory of Precision Medicine for Gastrointestinal Tumor, Nanfang Hospital, Southern Medical University, Guangzhou, China.

Phosphodiesterase-5 (PDE5) inhibitors have shown promise as anti-cancer agents in malignancies. However, their specific effects on gastric cancer (GC) and the underlying mechanisms remain elusive. Our aim was to investigate this by combining evidence from population-based studies with data obtained from in vivo and in vitro experiments.
