Guidelines for Use of Prostaglandin E1 Infusion (PGE-1, Alprostadil) Guidelines for Use of Prostaglandin E1 Infusion (PGE-1, Alprostadil) Recommended Neonatal Dose, Route, and Interval: Initial dose: 0.05 - 0.1mcg/kg/min IV continuous infusions. May advance to 0.2 mcg/kg/min if necessary. Higher doses may have an increased incidence of adverse effects without improvement of oxygenation. Maintenance dose: Once increase in PaO2 is obtained, decrease the infusion to the lowest effective dose (may be as low as 0.01 mcg/kg/min). Chief Indications: 1. Maintains patency of ductus arteriosus in neonates with ductal – dependant congenital heart lesions until surgery can be done. 2. Improve shunting after balloon septostomy has failed to improve oxygenation in certain cases of complete transposition of the great arteries. Possible Adverse Reactions: 1. Apnea (in up to 15% of patients) 6. Thrombocytopenia 2. Fever 7. Hypoglycemia, hypocalcaemia 3. Seizure 8. Diarrhea 4. Hypotension & Bradycardia 9. lethargy 5. Cortical hyperostosis with prolonged use Contraindications & Precautions: 1. Hypersensitivity to prostaglandin E 2. PPHN 3. Total anomalous pulmonary venous return with obstruction 4. Caution use in presence of bleeding tendencies or seizure disorders. Nursing Implications: 1. Obtain baseline vital signs, monitor ECG & BP closely 2. Assess for ductal patency and for improvement in oxygenation 3. Monitor for respiratory depression and be prepared for intubation. 4. Monitor infant’s temperature closely 5. Maintain patient’s IV at all times. Have two IV sites to avoid interruption of PGE infusion 6. Solution compatibility : D5W, NS 7. Two RN signatures are required to verify that physician order is calculated within guidelines and that the infusion rate is accurate 8. All meds mixed by pharmacy have a 24hr sterility expiration 9. Standard concentration prepared by pharmacy is 10mcg/mL in D5W or NS. References: 1. Neofax, Twenty Second edition 2009. 2.

  • 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).

  • Misoprostol Tablets
    Cytotec® misoprostol tablets WARNINGS CYTOTEC (MISOPROSTOL) ADMINISTRATION TO WOMEN WHO ARE PREGNANT CAN CAUSE BIRTH DEFECTS, ABORTION, PREMATURE BIRTH OR UTERINE RUPTURE. UTERINE RUPTURE HAS BEEN REPORTED WHEN CYTOTEC WAS ADMINISTERED IN PREGNANT WOMEN TO INDUCE LABOR OR TO INDUCE ABORTION. THE RISK OF UTERINE RUPTURE INCREASES WITH ADVANCING GESTATIONAL AGES AND WITH PRIOR UTERINE SURGERY, INCLUDING CESAREAN DELIVERY (see also PRECAUTIONS and LABOR AND DELIVERY). CYTOTEC SHOULD NOT BE TAKEN BY PREGNANT WOMEN TO REDUCE THE RISK OF ULCERS INDUCED BY NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs) (see CONTRAINDICATIONS, WARNINGS, and PRECAUTIONS). PATIENTS MUST BE ADVISED OF THE ABORTIFACIENT PROPERTY AND WARNED NOT TO GIVE THE DRUG TO OTHERS. Cytotec should not be used for reducing the risk of NSAID-induced ulcers in women of childbearing potential unless the patient is at high risk of complications from gastric ulcers associated with use of the NSAID, or is at high risk of developing gastric ulceration.

Misoprostol (CytotecTM), is an oral prostaglandin E analogue. The purpose of this study was to compare the functional activity of misoprostol with PGE1 in human corpus cavernosum and cultured human corpus cavernosum smooth muscle cells. Misoprostol, misoprostol free acid or PGE1 induced dose-dependent relaxations in strips of human corpus cavernosum. At concentrations greater than 1076 M, tissue recontraction was observed with all three agents. This was abrogated by pretreatment with the thromboxane A2 receptor antagonist SQ29,548. From these observations, we conclude that misoprostol is activated by human corpus cavernosum in situ and relaxes phenylephrine-precontrated tissue

(Received 1 September 2004; and accepted 29 September 2004) ABSTRACT Prostaglandin E (PGE) induces the penile erection in the mammalians. Receptors for PGE were characterized to 4 different subtypes (EP1–4). The effects of agonists for EP1–4 receptors were studied on phenylephrine (PE, 1 μM)-induced contractions in the rabbit penile corpus cavernosum smooth muscle. The EP4 receptor agonist, ONO-AE1-329 (1 pM–10 μM), markedly relaxed the pre-contracted smooth muscle strips in a concentration-dependent fashion (−65 ± 16% relaxation at 10 nM). The EP2 receptor agonists, ONO-AE1-259-01 (1 nM–10 μM) or butaprost (1 nM–10 μM), also relaxed the smooth muscle strips in a concentration dependent fashion (−58 ± 10% re- laxation at 10 μM or −53 ± 10% relaxation at 10 μM). The EP1 receptor agonist, ONO-DI-004 (0.01–10 μM), increased the contractility in the smooth muscle strips. A 12 ± 6% increase was ob- served with 10 μM of the agonist. The EP3 receptor agonist, ONO-AE-248 (0.01–10 μM), howev- er, did not alter the contractility of the smooth muscle strips. The selective EP4 receptor antagonist, ONO-AE3-208 (0.1 μM), inhibited a relaxant response to ONO-AE1-329 (the EP4 re- ceptor agonist) but did not affect a relaxant response to ONO-AE1-259-01 (the EP2 receptor ago- nist).

Downloaded from Gut, 1977, 18, 429-437 Effect of the prostaglandin precursor, arachidonic acid, on histamine stimulated gastric secretion in the conscious dog, and observations on the effect of inhibiting endogenous prostaglandin synthesis M. E. CONOLLY1, P. R. BIECK, N. A. PAYNE, B. ADKINS, AND J. A. OATES From the Division of Clinical Pharmacology, Vanderbilt University Medical Center, Nashville, Tennessee 37232, USA SUMMARY The effects of intravenous infusions of prostaglandin E2 (PGE2) and arachidonic acid (AA) on histamine-stimulated gastric secretion have been studied in conscious dogs with either a simple gastric fistula or a denervated Heidenhain pouch. Both compounds produced a dose-related inhibition of acid secretion, though AA was 86-5 to 203'2 times less potent than PGE2. The maximal effect ofAA was not achieved until 20 to 40 minutes after the infusion had ceased, suggesting that AA has to undergo some kinetic or metabolic process before it can act. Eicosatetraynoic acid (ETYN) 1-0 pg.kg-1min-1, an inhibitor of PG biosynthesis, almost totally abolished the anti-secretory effect of AA up to 200 ,ug.kg-1min-1. At 400 jig AA.kg-lmin-1, the antisecretory effect was reduced by about one half. The effect of PGE2 was not altered by ETYN. Furthermore, ETYN did not increase the response to histamine stimulation in control studies, which suggests that, in this model at least, prostaglandins are not involved in regulating gastric secretion. http://gut.bmj.com/ Prostaglandins (PG) have been studied extensively as venous infusion of PGE1 does reduce acid output.
