  • A burst of fenoterol excretion during the recovery of a weight loss protocol. [Journal Article]
    J Pharm Biomed Anal. 2023 Feb 20; 225:115209.Cheibub AM, Muniz-Santos R, … Cameron LC
  • Fenoterol is a sympathomimetic β2 receptor agonist primarily used as a bronchodilator. Due to its sympathomimetic actions, the World Anti-Doping Agency (WADA) has banned it. Multiple acute weight loss protocols (WLP) are used by Olympic athletes for sports that segregate athletes by weight; these generally involve caloric and water deprivation combined with heat exposure. Athletes use WLP before …
  • Molecular basis for stereoselective transport of fenoterol by the organic cation transporters 1 and 2. [Journal Article]
    Biochem Pharmacol. 2022 03; 197:114871.Gebauer L, Arul Murugan N, … Rafehi M
  • Stereoselectivity is important in many pharmacological processes but its impact on drug membrane transport is scarcely understood. Recent studies showed strong stereoselective effects in the cellular uptake of fenoterol by the organic cation transporters OCT1 and OCT2. To provide possible molecular explanations, homology models were developed and the putative interactions between fenoterol enanti…
  • Validation of Fenoterol to Study β2-Adrenoceptor Function in the Rat Urinary Bladder. [News]
    Pharmacology. 2022; 107(1-2):116-121.Erdogan BR, Yesilyurt ZE, … Michel MC
  • Fenoterol is a β2-adrenoceptor (AR)-selective agonist that is commonly used to investigate relaxation responses mediated by β2-AR in smooth muscle preparations. Some data have questioned this because fenoterol had low potency in the rat urinary bladder when a muscarinic agonist was used as a pre-contraction agent and because some investigators proposed that fenoterol may act in part via β3-AR. We…
  • Drugs and Lactation Database (LactMed): Metaproterenol [BOOK]
    Drugs and Lactation Database (LactMed). National Library of Medicine (US): Bethesda (MD)BOOK
  • Although no published data exist on the use of metaproterenol by mouth or inhaler during lactation, data from the related drug, terbutaline, indicate that very little is expected to be excreted into breastmilk.[1] The authors of several reviews and an expert panel agree that use of inhaled bronchodilators is acceptable during breastfeeding because of the low bioavailability and maternal serum lev…
  • Stereoselective cell uptake of adrenergic agonists and antagonists by organic cation transporters. [Journal Article]
    Biochem Pharmacol. 2020 01; 171:113731.Jensen O, Rafehi M, … Brockmöller J
  • Stereoselectivity is well described for receptor binding and enzyme catalysis, but so far has only been scarcely investigated in carrier-mediated membrane transport. We thus studied transport kinetics of racemic (anti)adrenergic drugs by the organic cation transporters OCT1 (wild-type and allelic variants), OCT2, OCT3, MATE1, and MATE2-K with a focus on stereospecificity. OCT1 showed stereoselect…
  • Myoclonus induced by salbutamol: A case report [Case Reports]
    Biomedica. 2018 09 01; 38(3):303-307.Montoya-Giraldo MA, Montoya DV, … Zuluaga AF
  • Salbutamol is a β2 adrenergic agonist widely prescribed in patients with obstructive and restrictive lung diseases. The main side effects associated with its use are tachycardia and tremor. Myoclonus is an involuntary, irregular, abrupt, brief and sudden muscular contraction, which can be generalized, focal or multifocal. We report the case of a 61-year-old patient presenting with myoclonus diffi…
  • Effect of dual tocolysis with fenoterol and atosiban in human myometrium. [Journal Article]
    J Perinat Med. 2019 Feb 25; 47(2):190-194.Stoiber B, Haslinger C, … Schäffer L
  • Objectives To measure the tocolytic effect of the combination of the oxytocin receptor antagonist atosiban with the β-mimetic agent fenoterol on human myometrium of pregnant women. Methods An in vitro study of contractility in human myometrium at the Laboratory of the Department of Obstetrics, University Hospital of Zürich, Switzerland, was performed. Thirty-six human myometrial biopsies were obt…
  • Acute tocolysis for uterine tachysystole or suspected fetal distress. [Review]
    Cochrane Database Syst Rev. 2018 07 04; 7:CD009770.Leathersich SJ, Vogel JP, … Hofmeyr GJ
  • CONCLUSIONS: There is insufficient evidence to determine the effects of tocolytics for uterine tachysystole or suspected fetal distress during labour. The clinical significance for some of the improvements in measures of fetal well-being with tocolytics is unclear. The sample sizes were too small to detect effects on neonatal morbidity, mortality or serious adverse effects. The majority of studies are from high-income countries in facilities with access to caesarean section, which may limit the generalisability of the results to lower-resource settings, or settings where caesarean section is not available.Further well-designed and adequately powered RCTs are required to evaluate clinically relevant indicators of maternal and neonatal morbidity and mortality.
