Abstract
Opioids are widely being used for chronic pain management, cough and diarrhea suppressants, anesthetic agents, and opioid de-addiction therapy. Opioid receptors, present in the central nervous system and peripheral tissues, are documented to regulate several cardiac functions through different signaling pathways. Long-acting opioids (LAO) have been successfully evaluated for their beneficial effects in various cardiovascular diseases viz. myocardial infarction, ischemic reperfusion injuries, atherosclerosis etc. However, on the other hand, several research studies pointed towards the harmful effects of LAOs which are mainly associated with QTc prolongation, torsade de pointes, ventricular arrhythmias, and cardiac arrest. This review shall familiarize readers with the benefits as well as the harmful effects of long-acting opioids in cardiovascular diseases. We have also provided an overview of cardiac opioid receptors, endogenous cardiac opioid peptides, and regulation of cardiovascular functions by central and cardiac opioid receptors.

Abstract
Cardiovascular disease (CVD) is a significant cause of morbidity and mortality across the world. A large proportion of CVD deaths are secondary to coronary artery disease (CAD) and myocardial infarction (MI). Even though prevention is the best strategy to reduce risk factors associated with MI, the use of cardioprotective interventions aimed at improving patient outcomes is of great interest. Opioid conditioning has been shown to be effective in reducing myocardial ischemia-reperfusion injury (IRI) and cardiomyocyte death. However, the molecular mechanisms behind these effects are under investigation and could provide the basis for the development of novel therapeutic approaches in the treatment of CVD. Non-coding RNAs (ncRNAs), which are functional RNA molecules that do not translate into proteins, are critical modulators of cardiac gene expression during heart development and disease. Moreover, ncRNAs such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are known to be induced by opioid receptor activation and regulate opioid signaling pathways. Recent advances in experimental and computational tools have accelerated the discovery and functional characterization of ncRNAs. In this study, we review the current understanding of the role of ncRNAs in opioid signaling and opioid-induced cardioprotection.

Abstract
It has now been demonstrated that the μ, δ1 , δ2 , and κ1 opioid receptor (OR) agonists represent the most promising group of opioids for the creation of drugs enhancing cardiac tolerance to the detrimental effects of ischemia/reperfusion (I/R). Opioids are able to prevent necrosis and apoptosis of cardiomyocytes during I/R and improve cardiac contractility in the reperfusion period. The OR agonists exert an infarct-reducing effect with prophylactic administration and prevent reperfusion-induced cardiomyocyte death when ischemic injury of heart has already occurred; that is, opioids can mimic preconditioning and postconditioning phenomena. Furthermore, opioids are also effective in preventing ischemia-induced arrhythmias.

Abstract
OBJECTIVES The objective of this study was to investigate the role of peripheral μ, δ1, δ2, and nociceptin opioid receptors agonists in the regulation of cardiac tolerance to the arrhythmogenic effect of ischemia/reperfusion in rats. METHODS Anesthetized open-chest male Wistar rats were subjected to either 45 minutes of left coronary artery occlusion (phase 1a 10 minutes and phase 2b 35 minutes) and 2 hours of reperfusion in Experiment 1 or 10 minutes of ischemia and 10 minutes of reperfusion in Experiment 2. In Experiment 1, saline or vehicle controls and the mu-specific opioids dermorphin-H (Derm-H) and ([d-Ala2, N-Me-Phe4, Gly-ol5] enkephalin (DAMAGO); the delta-1-specific opioid d-Pen2,5enkephalin (DPDPE); nociceptin; and the delta-2-specific opioids deltorphin-II (Delt-II), Delt-Dvariant (Delt-Dvar), and deltorphin-E (Delt-E) were infused 15 minutes prior to ischemia. In Experiment 2, DPDPE, Delt-D, Delt-Dvar, and Delt-E were infused at 15 minutes prior to ischemia. The universal opioid receptor antagonist naltrexone, the peripherally acting antagonist naloxone methiodide, the selective δ1 antagonist 7-benzylidene naltrexone maleate, and the specific δ2 antagonist naltriben mesylate were infused 25 minutes prior to ischemia. RESULTS In Experiment 1, pretreatment with the μ opioids Derm-H and DAMGO, DPDPE, and nociceptin at all doses tested did not reduce the incidence of ischemia-induced arrhythmias compared to controls during 45 minutes of ischemia. The δ2 opioids Delt-II (0.12 mg/kg), Delt-Dvar (0.3 mg/kg), and Delt-E (0.18 mg/kg) all demonstrated significant antiarrhythmic effects at the 150 nmol/kg dose compared to saline or vehicle controls. Nine of 19 animals treated with Delt-II were tolerant without ventricular arrhythmias to the arrhythmogenic effect of ischemia during the first 10 minutes of ischemia (phase 1a) and 11 of 19 were without ventricular arrhythmias during the following 35 minutes of ischemia (phase 1b). Delt-II also decreased the incidence of premature ventricular contractions and ventricular tachycardia by almost half during phase 1a. Delt-II did not affect the incidence of ventricular fibrillation (VF). Pretreatment with Delt-Dvar and Delt-E completely blocked the incidence of VF in phase 1b. Delt-E also decreased premature ventricular contractions by 50%, and the incidence of ventricular tachycardia decreased over twofold in phase 1b of ischemia. There was no enhanced tolerance by any of the delta-2 opioids to the arrhythmogenic effect of reperfusion after long-term ischemia. In Experiment 2, after 10 minutes of ischemia and 10 minutes of reperfusion, Delt-II (0.12 mg/kg) reduced the incidence of premature ventricular contractions and ventricular tachycardia compared to controls, and completely blocked the incidence of VF following 10 minutes of reperfusion. Delt-Dvar and Delt-E were without effect, as was DPDPE following 10 minutes of reperfusion. The antiarrhythmic effect of Delt-II during 10 minutes of ischemia and 10 minutes of reperfusion was completely blocked by the peripherally acting opioid receptor inhibitor naloxone methiodide and the selective delta-2 opioid receptor inhibitor naltriben mesylate, but not by the selective delta-1 inhibitor 7-benzylidene naltrexone maleate. The antagonists alone had no effect on arrhythmogenesis. CONCLUSIONS Peripheral delta-2 opioid receptor activation by Delt-II, Delt-Dvar, and Delt-E enhanced cardiac tolerance to the arrhythmogenic effects of ischemia.

Abstract
BACKGROUND Despite several recent innovations in phacoemulsification surgery, importance of pupil diameter in this surgery is becoming more evident. PURPOSE To compare the effect of opioid agonist (fentanyl) versus opioid agonist-antagonist (buprenorphine) on pupil diameter in cataract surgery and to choose the best opioid in high-risk phacoemulsification surgery. METHODS In this randomized double-blinded clinical trial, 60 patients who were candidates for elective phacoemulsification surgery were randomly divided into two equal groups: experimental (buprenorphine, 0.3 μg/kg) and control (fentanyl, 1 μg/kg). Pupil diameter was measured preinjection and at several times postinjection. Blood pressure was recorded at several intervals, as well as shivering, nausea and vomiting, and recovery time. RESULTS Mean (SD) recovery time was significantly less in the control group (19.46±5.43) than in the experimental group (33.23±10.75) (P<0.0001). The constriction effect (ie, pupillary diameter in mm) was significantly lower in the experimental group (0.53±0.45) than in the control group (1.06±0.52) (P=0.0001). The percentages of constriction effect in experimentaland control groups were 7.68% and 15.07%, respectively. The eye was two times more constricted in the control group in comparison with the experimental group after induction of anesthesia. CONCLUSION Buprenorphine is a better solution to decrease pupil constriction in comparison with fentanylinhigh-risk phacoemulsification surgery.

Abstract
Abstract
Intracellular microelectrodes were used to study the electrophysiological effects of morphine on guinea-pig papillary muscle. Morphine (5 × 10−4 m) caused a significant decrease in the maximum rate of depolarization. At high concentrations (5 × 10−3 m) morphine induced a decrease in the action potential amplitude and a prolongation of the action potential duration. The administration of naloxone (10−7 m) partially antagonized the cardiac electrophysiological effects of morphine. These results suggest that the electrophysiological effects of morphine may be due to an interaction with opioid receptors.

Abstract
Endogenous opioid peptides are the basis of a diverse system of complex neuroregulatory and endocrine mechanisms. While relatively quiescent in the resting state, these peptides are released during intense stimulation and modify, in a number of ways, circulatory homeostatic mechanisms. The endogenous opioids, primarily via endorphins and enkephalins, are capable of influencing circulatory responses to stress at the behavioral, the endocrinological, and the neural level. Recent research in humans and animals has described several roles for opioids in regulation of the circulatory stress response, and has also provided clues about the significance of opioid dysregulation in the pathophysiology of stress. Increased understanding of the basic mechanisms of stress and endogenous opioids will clarify the potential roles of opioids in important pharmacologic and behaviorally based therapeutics.

Abstract
The objectives of this study were to test the hypothesis that dynorphin in the central nervous system modulates epinephrine-induced cardiac arrhythmias and that central cholinergic mechanisms are operative in this action of dynorphin. Cardiac arrhythmias were produced by continuous intravenous infusion of epinephrine, in Wistar rats, previously instrumented with catheters in the lateral cerebral ventricle, femoral vein and femoral artery. Epinephrine produced ventricular premature complexes and later the development of fatal ventricular fibrillation. Dynorphin A (1-13), 5 or 20 micrograms (3 or 12 nM) administered into the lateral cerebral ventricle (ICV), significantly (P less than 0.05) increased the threshold for development of cardiac arrhythmias. Dynorphin A (1-13), 20 micrograms, increased the epinephrine dose at the occurrence of ventricular premature beats to 171 +/- 8 (mean +/- 1 S.E.M.) compared to 120 +/- 5 micrograms epinephrine/kg in the control group and increased the dose at the onset of fatal arrhythmias to 186 +/- 8 compared to 141 +/- 10 micrograms epinephrine/kg in the control group. The action of dynorphin was significantly (P less than 0.05) antagonized by the kappa opioid antagonist MR2266. Atropine sulfate, administered ICV or intravenously, produced a dose dependent antagonism of this action of dynorphin A (1-13). This was not due to the peripheral effects of atropine, as atropine methylnitrate, which does not cross the blood brain barrier, did not oppose the effects of dynorphin A (1-13). These data indicate (i) dynorphin A (1-13) increases the threshold for or suppresses the manifestations of epinephrine-induced ventricular arrhythmias, (ii) dynorphin's action on cardiac arrhythmias is mediated through central cholinergic rather than peripheral parasympathetic mechanisms (iii) dynorphin may play a role as an endogenous opioid within the brain that modulates cardiac arrhythmias in circumstances of elevated circulating epinephrine concentration.

Abstract
The purpose of this study was to examine the hypothesis that the calcium channel blocker, diltiazem, modulates catecholamine-induced arrhythmias through CNS mechanisms. Rats, that had catheters previously inserted into the lateral cerebral ventricle and femoral artery, received diltiazem, 10 or 50 micrograms/kg or the diluent, into the lateral cerebral ventricle (i.c.v.). Epinephrine was infused to produce arrhythmias. The onset of ventricular arrhythmias, premature ventricular complexes, occurred at a significantly (P less than 0.05) greater dose of epinephrine, after diltiazem, compared to the control group and in a dose-dependent manner, with the mean (+/- 1 SEM) dose of epinephrine being 198 +/- 5, 175 +/- 13 and 115 +/- 15 micrograms/kg in the groups treated with 50 and 10 micrograms/kg of diltiazem and the control groups, respectively. The development of fatal arrhythmias, mainly ventricular tachyarrhythmias, occurred at significantly (P less than 0.05) greater concentrations of epinephrine with diltiazem, 50 and 10 micrograms/kg, 225 +/- 5 and 183 +/- 13 micrograms/kg, respectively, compared to controls, 131 +/- 15 micrograms/kg. Endogenous opioids of the mu-type were implicated in this action of diltiazem, because the mu opioid antagonist naloxone, 1 mg/kg (i.v.), significantly (P less than 0.05) antagonized the antiarrhythmic effects of centrally administered diltiazem and the mu opioid agonist DAGO (i.c.v.), did not further enhance the suppression of epinephrine-induced arrhythmias, produced by diltiazem, 50 micrograms/kg. Atropine sulfate, which crosses the blood-brain barrier and atropine methylnitrate, which does not enter the brain, each at 1 mg/kg (i.v.), produced an equal and significant antagonism of the effect of diltiazem, 50 micrograms/kg, that was less than that of naloxone. The combination of naloxone plus atropine sulfate completely prevented the effect of diltiazem, 50 micrograms/kg, on arrhythmias. The antiarrythmic action of diltiazem could not be explained by alteration of the blood pressure or heart rate response to epinephrine. The results suggest that: (a) calcium channels on neurons in the CNS play an important role in the modulation of epinephrine-induced cardiac arrhythmias, (b) diltiazem can suppress arrhythmias through CNS mechanisms, (c) activation of the parasympathetic nervous system mediates some of the effect of diltiazem, but (d) the mechanism of action of diltiazem is modulated through endogenous opioids.
