analgesia

Medetomidine hydrochloride (MPV785) is a selective α2-adrenoceptor agonist, with Ki of 1.08 nM, exhibts 1620-fold selectivity over α1-adrenoceptor.

Oxeladin citrate is a highly potent and effective cough suppressant, which can treat all types of cough of various etiologies. It is not related to opium or its derivatives, so treatment with oxeladin is no risk of addiction. And it has none of the side effects (such as hypnosis, respiratory depression, tolerance, constipation and analgesia) which are present when common antitussives. It can used at every age, as well as in patients with heart disease, since it is high level of safety and a great selectivity to act on the bulbar centre of cough.

Halothane (Anestan) is a nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required.

Parecoxib (SC 69124) is an effective and selective COX-2 inhibitor.

Levobupivacaine is an amino-amide local anaesthetic drug belonging to the family of n-alkylsubstituted pipecoloxylidide. It is the S-enantiomer of bupivacaine. Levobupivacaine hydrochloride is commonly marketed by AstraZeneca under the trade name Chirocaine. Compared to bupivacaine, levobupivacaine is associated with less vasodilation and has a longer duration of action. It is approximately 13 per cent less potent (by molarity) than racemic bupivacaine.Levobupivacaine is indicated for local anaesthesia including infiltration, nerve block, ophthalmic, epidural and intrathecal anaesthesia in adults; and infiltration analgesia in children. Adverse drug reactions (ADRs) are rare when it is administered correctly. Most ADRs relate to administration technique (resulting in systemic exposure) or pharmacological effects of anesthesia, however allergic reactions can rarely occur.

Dexmedetomidine is a Central alpha-2 Adrenergic Agonist. The mechanism of action of dexmedetomidine is as an Adrenergic alpha2-Agonist. The physiologic effect of dexmedetomidine is by means of General Anesthesia.

(+)-BORNEOL (d-Borneol) is a natural bicyclic monoterpene used for analgesia and anesthesia in traditional Chinese medicine; enhances GABA receptor activity with an EC50 of 248 μM.

Dexmedetomidine hydrochloride (Precedex) is a potent, selective, orally active α2-adrenoceptor agonist with a Ki value of 1.08 nM. It shows 1620-fold selectivity over α1-adrenoceptors. Dexmedetomidine hydrochloride (Precedex) can protect against sepsis-induced acute lung injury through anti-inflammatory, anti-oxidative, and anti-apoptotic effects.

Flupirtine maleate (Katadolon maleate), a centrally acting non-opioid analgesia, is the salt form of Flupirtine. It is an NMDA receptor antagonist , and also a specific neuronal potassium channel opener.

Dibutyryl-cGMP sodium (Bt2cGMP sodium) is a cell-permeable cGMP analog that preferentially activates cGMP-dependent protein kinase (PKG). It inhibits [3H]-arachidonic acid release in human platelets stimulated by gamma thrombin and can induce peripheral analgesia by activating ATP-sensitive K+ channels.

Methylnaltrexone bromide (MOA-728) is one of the newer agents of peripherally-acting μ-opioid antagonists. Methylnaltrexone bromide acts to reverse some of the side effects of opioid drugs such as constipation without affecting analgesia or precipitating withdrawals.

Org 25543 is the development of an N-Acyl amino acid that selectively inhibits the glycine transporter 2 to produce analgesia in a rat model of chronic pain.

Solabegron (GW-427,353), is a selective agonist of β3 adrenergic receptors. In addition, Solabegron has been shown to produce visceral analgesia by releasing somatostatin from fat cells.

Kyotorphin acetate is an endogenous peptide with analgesia activity and can be used as a biomarker of Alzheimer disease.

NeoSTX (Neosaxitoxin) is a specific sodium channel blocker that targets site 1. It works synergistically with local anesthetics to provide surgical anesthesia through peripheral nerve block or local infiltration and significantly prolongs postoperative analgesia duration.

exo-Tetrahydrocannabivarin (Compound 12) is an analog of Δ9,11-THC. It weakly binds to cannabinoid receptors (CB) with an IC50 of 1.4 μM. In mice, exo-Tetrahydrocannabivarin exhibits activity related to both motor function and analgesia.

N-Phenethylnoroxymorphone is an opioid compound that can enhance morphine-induced analgesia in rats. It is used in the research of neurological disorders.

Leucinal inhibits the activity of brain aminopeptidase and potentiates analgesia induced by leu-enkephalen.

LY 190388 is a penicillamine-containing enkephalin analog used as an mu receptor agonist with analgesia activity.

Dafphedyn, [D-Ala2, (F5) Phe4]-dynorphin 1-13-NH2 (DAFPHEDYN) is an effective analog of strong endorphin 1-13 and produces diuretic and deep analgesia when administered intravenously in rats.

D-Kyotorphin is a synthetic neuropeptide kyotorphin analog that produces naloxone reversible analgesia.

Propiomazine HCl is an analgesia adjunct.

Deltorphin II is a peptide agonist of δ2-opioid receptors.1,2It is selective for δ-opioid receptors over μ- and κ-opioid receptors in radioligand bindings assays (Kis = 0.0033, >1, and >1 μM, respectively) and induces [35S]GTPγS binding in mouse brain membrane preparations (EC50= 0.034 μM). Deltorphin II (0.12 mg/kg) decreases the infarction zone:risk zone ratio in a rat model of myocardial ischemia-reperfusion injury induced by coronary occlusion, an effect that can be reversed by the δ2-opioid receptor antagonist naltriben but not the δ1-opioid receptor antagonist BNTX.3Intrathecal administration of deltorphin II (15 μg/animal) increases latency to withdraw in the paw pressure and tail-flick tests in rats.4 1.Raynor, K., Kong, H., Chen, Y., et al.Pharmacological characterization of the cloned κ-, δ-, and μ-opioid receptorsMol.

URB754 is a potent and noncompetitive inhibitor of monoacylglycerol lipase (MAGL), exhibiting an IC50 value of 200 nM for the recombinant rat brain enzyme. However, it does not inhibit human recombinant, rat brain, or mouse brain MAGL at concentrations up to 100 μM. There is evidence that the MAGL inhibitory activity of URB754 may be attributed to the impurity bis(methylthio)mercurane (IC50 = 11.9 nM for rat recombinant MAGL) that is found in commercial preparations. URB754 inhibits rat brain fatty acyl amide hydrolase (FAAH) with an IC50 value of 32 μM and binds weakly to the rat central cannabinoid (CB1) receptor with an IC50 value of 3.8 μM. It does not inhibit COX-1 or COX-2 at concentrations up to 100 μM. Inhibition of MAGL hydrolysis of 2-arachidonoyl glycerol (2-AG) is associated with enhanced stress-induced analgesia and may represent a novel drug target in pain and stress management.
