Engineered Multifunctional Drug-Loaded Dendrimer Nanoparticles for Glaucoma: Triple Mechanism via Antioxidant Activity, Iron Chelation, and Enhanced Ocular Transport. (PubMed, Biomacromolecules) - "In this study, we developed multifunctional nanoparticles based on polyamidoamine (PAMAM) dendrimers functionalized with caffeic acid (CA) and poly(ethylene glycol) maleimide (PEGM) for the topical delivery of hydrophobic antiglaucoma drugs brimonidine (BM) and betaxolol (BX). Both PAMAM-CA and PAMAM-CA-PEGM nanoparticles exhibited concentration-dependent antioxidant activity comparable to that of CA. These findings suggest the potential of this multifunctional dendrimer-based nanoparticle system as an innovative strategy for glaucoma medication."

Enhanced ocular retention and intraocular pressure-lowering efficacy of hydrophobic microspheres for glaucoma treatment. (PubMed, Colloids Surf B Biointerfaces) - "This study aimed to address these challenges by developing betaxolol hydrochloride-loaded mesoporous silica polyacrylic resin microspheres (BH@MCM-41 MPs) and comparing their safety, ocular retention, and intraocular pressure (IOP)-lowering efficacy with previously reported betaxolol hydrochloride-loaded montmorillonite polyacrylic resin microspheres (BH@MMT MPs), BH solution, and commercially available Betoptic®...The area under the IOP reduction curve (AUC0-36h) for BH@MCM-41 MPs was 1.2-fold greater than for BH@MMT MPs, and significantly higher than for the BH solution and Betoptic. These findings suggest that BH@MCM-41 MPs offer enhanced efficacy for sustained glaucoma treatment through improving precorneal retention."

The Effectiveness of Liquid-Phase Microextraction of Beta-Blockers from Aqueous Matrices for Their Analysis by Chromatographic Techniques. (PubMed, Molecules) - "The aim of this research is to test the effectiveness of two green liquid-phase microextraction procedures, such as dispersive liquid-liquid microextraction (DLLME) and solidification of floating organic droplet microextraction (SFOME) for the selective extraction of eight beta-blockers (atenolol, nadolol, pindolol, acebutolol, metoprolol, bisoprolol, propranolol, and betaxolol) from aqueous matrices for their analysis by gas chromatography (GC) or liquid chromatography (LC). Good limits of detection (0.13 to 0.69 µg/mL for GC and 0.07 to 0.15 µg/mL for HPLC) and limits of quantification (0.39 to 2.10 µg/mL for GC and 0.20 to 0.45 µg/mL for LC) were obtained. The developed procedures were successfully applied to the analysis of selected beta-blockers in wastewater samples, proving their applicability to the real samples."

Restraint stress effects on glutamate signaling protein levels in the rats' frontal cortex: Does β1 adrenoceptor activity matter? (PubMed, Front Pharmacol) - "In the current study, we adopted a restraint stress (RS) model in male Wistar rats to investigate whether the blockade of β1 adrenergic receptors (β1AR) with betaxolol (BET) in stressed animals influences the body's stress response and the expression of selected signaling proteins in the medial prefrontal cortex (mPFC)...β1AR blockade normalized only the blood concentration of ACTH. These results suggest that decreased Fyn kinase activity, indicated by phosphorylation at Y530, underlies the stress-evoked downregulation of GluN2B in the FC in a manner independent of β1AR activity."

β-Blockers and Asthma: Surprising Findings from the FAERS Database. (PubMed, Respir Med) - "Risk stratification underscores the need for cautious β-blocker selection in asthmatic patients or those predisposed to asthma. The study highlights significant variability in risk among different β-blocker classes, crucial for clinical decisions and patient outcomes. Drugs like esmolol, metoprolol, nebivolol, and nadolol may be safer for asthmatic patients, whereas betaxolol, bisoprolol, timolol, and propranolol should be avoided. Regular respiratory monitoring is crucial for asthmatic patients on β-blockers, starting treatment at low doses and adjusting to minimize bronchoconstriction risk."

Spatiotemporal dynamics of reactive oxygen species and its effect on beta-blockers' degradation in aquatic plants' rhizosphere. (PubMed, J Hazard Mater) - "Through mass balance analysis and quenching experiment, we revealed that ROS contributed significantly to rhizodegradation for beta-blockers, ranging from 22.18 % for betaxolol to 83.83 % for atenolol. ROS production patterns were driven by rhizosphere chemistry (Fe and humic substances) and microbiome variations in different rhizocompartments. These findings not only deepen understanding of ROS production in aquatic plants rhizosphere but also shed light on advancing phytoremediation strategies."

Sex differences in hippocampal β-adrenergic receptor subtypes drive retrieval, retention, and learning of cocaine-associated memories. (PubMed, Front Behav Neurosci) - "Rats were infused directly to the dorsal hippocampus with Propranolol (β1 and β2) or ICI-118,551 (β1) and/or Betaxolol (β2), immediately prior to testing (retrieval), or paired to each cocaine (10 mg/kp, IP) conditioning session (learning). Furthermore, sub regions of the dorsal hippocampus appear to activate differently between male and female rats during CPP. Therefore DG, CA3, and CA1 may have separate region- and sex-specific impacts on driving drug- associated, or context-associated cues."

Sex Differences in Contextual Cocaine Seeking Behavior are Driven by Noradrenergic Signaling to the Dorsal Hippocampus (CPDD 2024) - "We administered β-AR antagonists (Betaxolol (β1) and/or ICI 118,551 (β2)) to the dHPC prior to retrieval in both CPP and CSP... There are significant sex differences in the role of dorsal hippocampus β-ARs in the encoding and expression of both Pavlovian and operant cocaine memories. Furthermore, these effects may be driven by sex differences in adrenergic tone between the locus coeruleus and dorsal hippocampus. Thus, the substantial sex differences in the retrieval and retention of cocaine memories may be driven in part by adrenergic signaling."

Different concentrations of betaxolol switch cell fate between necroptosis, apoptosis, and senescence in human corneal stromal cells. (PubMed, Chem Biol Interact) - "Finally, clinical concentrations of betaxolol had a pro-apoptotic effect on rabbit corneal stromal cells in vivo. These results suggest that betaxolol induces cytotoxicity in a concentration-dependent manner in HCSCs, and that caspase-8 and Bcl-2 family proteins may be critical switches in the conversion of different HCSC death mechanisms."

Paternal methamphetamine exposure induces higher sensitivity to methamphetamine in male offspring through driving ADRB1 on CaMKII-positive neurons in mPFC. (PubMed, Transl Psychiatry) - "Selective antagonist (betaxolol) for β1-adrenergic receptor (ADRB1) or its knocking-down virus were administrated into mPFC to regulate ADRB1 function and expression on CaMKII-positive neurons. In the process, the p-ERK1/2 and ΔFosB may be potential subsequent signals of mPFC ADRB1. The mPFC ADRB1 mediates paternal METH exposure-induced higher sensitivity to drug addiction in male offspring, raising a promising pharmacological target for predicting or treating transgenerational addiction."
