  • New Zealand Data Sheet
    NEW ZEALAND DATA SHEET 1. PRODUCT NAME PROSTIN 15M 250 microgram (µg)/mL Solution for Injection 2. QUALITATIVE AND QUANTITIATIVE COMPOSITION Each 1 mL contains 250 μg carboprost or 332 μg carboprost (as tromethamine). Excipient(s) with known effect Each 1 mL contains 9.45 mg/mL benzyl alcohol (added as preservative). For the full list of excipients, see section 6.1. 3. PHARMACEUTIAL FORM Solution for Injection. PROSTIN 15M is a clear colourless solution. 4. CLINCAL PARTICUALRS 4.1 Therapeutic indications PROSTIN 15M is indicated for the treatment of postpartum haemorrhage due to uterine atony which has not responded to conventional methods of management. Prior treatment should include the use of intravenously administered oxytocin, manipulative techniques such as uterine massage and, unless contraindicated, intramuscular ergot preparations. Studies have shown that in such cases, the use of PROSTIN 15M has resulted in satisfactory control of haemorrhage, although it is unclear whether or not ongoing or delayed effects of previously administered embolic agents have contributed to the outcome. In a high proportion of cases, PROSTIN 15M used in this manner has resulted in the cessation of life threatening bleeding and the avoidance of emergency surgical intervention. 4.2 Dose and method of administration Dose An initial dose of 250 µg (1 mL) is to be given by deep intramuscular injection. In clinical trials, it was found that the majority of successful cases (73%) responded to single injections. In some selected cases, however, multiple dosing at intervals of 15 to 90 minutes was carried out with successful outcome. The need for additional injections and the interval at which these should be given can be determined only by the attending physicians as dictated by the course of clinical events.

  • And NF-Κb-Dependent Mechanism
    www.nature.com/scientificreports OPEN Prostaglandin I2 Attenuates Prostaglandin E2-Stimulated Expression of Interferon γ in a Received: 17 September 2015 Accepted: 11 January 2016 β-Amyloid Protein- and NF-κB- Published: 12 February 2016 Dependent Mechanism Pu Wang*, Pei-Pei Guan*, Xin Yu, Li-Chao Zhang, Ya-Nan Su & Zhan-You Wang Cyclooxygenase-2 (COX-2) has been recently identified as being involved in the pathogenesis of Alzheimer’s disease (AD). However, the role of an important COX-2 metabolic product, prostaglandin (PG) I2, in AD development remains unknown. Using mouse-derived astrocytes as well as APP/ PS1 transgenic mice as model systems, we firstly elucidated the mechanisms of interferonγ (IFNγ) regulation by PGE2 and PGI2. Specifically, PGE2 accumulation in astrocytes activated the ERK1/2 and NF-κB signaling pathways by phosphorylation, which resulted in IFNγ expression. In contrast, the administration of PGI2 attenuated the effects of PGE2 on stimulating the production of IFNγ via inhibiting the translocation of NF-κB from the cytosol to the nucleus. Due to these observations, we further studied these prostaglandins and found that both PGE2 and PGI2 increased Aβ1–42 levels. In detail, PGE2 induced IFNγ expression in an Aβ1–42-dependent manner, whereas PGI2-induced Aβ1–42 production did not alleviate cells from IFNγ inhibition by PGI2 treatment. More importantly, our data also revealed that not only Aβ1–42 oligomer but also fibrillar have the ability to induce the expression of IFNγ via stimulation of NF-κB nuclear translocation in astrocytes of APP/PS1 mice. The production of IFNγ finally accelerated the deposition of βA 1–42 in β-amyloid plaques.

In most instances, the initial and rate-limiting step in eicosanoid synthesis is the liberation of intracellular arachidonate, usually in a one-step process catalyzed by the enzyme phospholipase A2 (PLA2).

  • Effect of Prostanoids on Human Platelet Function: an Overview
    International Journal of Molecular Sciences Review Effect of Prostanoids on Human Platelet Function: An Overview Steffen Braune, Jan-Heiner Küpper and Friedrich Jung * Institute of Biotechnology, Molecular Cell Biology, Brandenburg University of Technology, 01968 Senftenberg, Germany; steff[email protected] (S.B.); [email protected] (J.-H.K.) * Correspondence: [email protected] Received: 23 October 2020; Accepted: 23 November 2020; Published: 27 November 2020 Abstract: Prostanoids are bioactive lipid mediators and take part in many physiological and pathophysiological processes in practically every organ, tissue and cell, including the vascular, renal, gastrointestinal and reproductive systems. In this review, we focus on their influence on platelets, which are key elements in thrombosis and hemostasis. The function of platelets is influenced by mediators in the blood and the vascular wall. Activated platelets aggregate and release bioactive substances, thereby activating further neighbored platelets, which finally can lead to the formation of thrombi. Prostanoids regulate the function of blood platelets by both activating or inhibiting and so are involved in hemostasis. Each prostanoid has a unique activity profile and, thus, a specific profile of action. This article reviews the effects of the following prostanoids: prostaglandin-D2 (PGD2), prostaglandin-E1, -E2 and E3 (PGE1, PGE2, PGE3), prostaglandin F2α (PGF2α), prostacyclin (PGI2) and thromboxane-A2 (TXA2) on platelet activation and aggregation via their respective receptors. Keywords: prostacyclin; thromboxane; prostaglandin; platelets 1. Introduction Hemostasis is a complex process that requires the interplay of multiple physiological pathways. Cellular and molecular mechanisms interact to stop bleedings of injured blood vessels or to seal denuded sub-endothelium with localized clot formation (Figure1).

  • Prostaglandin D2 Inhibits Wound-Induced Hair Follicle Neogenesis Through the Receptor, Gpr44 Amanda M
    ORIGINAL ARTICLE Prostaglandin D2 Inhibits Wound-Induced Hair Follicle Neogenesis through the Receptor, Gpr44 Amanda M. Nelson1,5, Dorothy E. Loy2,5, John A. Lawson3,4, Adiya S. Katseff1, Garret A. FitzGerald3,4 and Luis A. Garza1 Prostaglandins (PGs) are key inflammatory mediators involved in wound healing and regulating hair growth; however, their role in skin regeneration after injury is unknown. Using wound-induced hair follicle neogenesis (WIHN) as a marker of skin regeneration, we hypothesized that PGD2 decreases follicle neogenesis. PGE2 and PGD2 were elevated early and late, respectively, during wound healing. The levels of WIHN, lipocalin-type prostaglandin D2 synthase (Ptgds), and its product PGD2 each varied significantly among background strains of mice after wounding, and all correlated such that the highest Ptgds and PGD2 levels were associated with the lowest amount of regeneration. In addition, an alternatively spliced transcript variant of Ptgds missing exon 3 correlated with high regeneration in mice. Exogenous application of PGD2 decreased WIHN in wild-type mice, and PGD2 receptor Gpr44-null mice showed increased WIHN compared with strain-matched control mice. Furthermore, Gpr44-null mice were resistant to PGD2-induced inhibition of follicle neogenesis. In all, these findings demonstrate that PGD2 inhibits hair follicle regeneration through the Gpr44 receptor and imply that inhibition of PGD2 production or Gpr44 signaling will promote skin regeneration.
