Dihydrocodeine is a Dihydrocodeine vs codeine opioid analgesic used for pain or severe dyspnea, or as an antitussive, either alone or compounded with acetaminophen or aspirin. From: Reference Module in Biomedical Sciences, In a randomized, double-blind comparison of the antitussive effect of dihydrocodeine 10 mg tds with levodropropizine 75 mg tds in Dihydrocodeine vs codeine with primary lung cancer or metastatic cancer there was no ificant difference between the two drugs as far as cough severity and the s of night wakings were concerned, both drugs leading to ificant improvement [ 3 ].

Other adverse effects reported by those taking dihydrocodeine included erythema of the abdomen and epigastric pain, although constipation, Dihydrocodeine vs codeine potential adverse effect of codeine derivatives, was not reported. Dihydrocodeine has been compared with nabilone, a synthetic cannabinoid, in the treatment of chronic neuropathic pain [ 4 ]. Dihydrocodeine provided better pain relief and was associated with fewer adverse effects. Only tiredness and nightmares were more frequent with dihydrocodeine.

Ghodse, S. Galea, in Side Effects of Drugs Annual Dihydrocodeine has been compared with nabilone, a synthetic cannabinoid, in the treatment of chronic neuropathic pain 51 C. All other investigations were normal. Her menses returned spontaneously 3 months after dosage reduction. Codeine and dihydrocodeine are morphine derivatives of low and moderate potency, respectively.

Codeine is used in combination with paracetamol for the relief of mild to moderate pain. Limited data on the efficacy of codeine to treat post-operative pain in animals are available Martins et al. Dihydrocodeine is also available as an oral preparation, and is an effective analgesic in human beings.

To date, no information concerning its clinical efficacy in animals is available, however extensive information on its antinociceptive properties in laboratory rodents and other species is available Miranda et al. Dihydrocodeine also acts centrally to raise the cough threshold. Its other CNS activities seem to be markedly less than those of codeine. Dihydrocodeine is marketed as an elixir, which is relatively palatable and well absorbed.

In humans, dihydrocodeine is well absorbed after oral administration. It has a serum half-life of about 3. The antitussive Dihydrocodeine vs codeine appears to persist for 6—12 h. Unfortunately there is no information available on the pharmacokinetics of dihydrocodeine in dogs. Although constipation has been reported in humans, it is an unusual occurrence and adverse effects are generally extremely uncommon. Codeine, dihydrocodeinemethadone, fentanyl, buprenorphine, and other opioids, sometimes clinically prescribed for maintenance therapy, are often detected in deaths associated for heroin addiction.

Monointoxication with one of these substances is the exception and additional CNS depressants, mainly alcohol and benzodiazepines, can be detected frequently Auriacombe et al. The neuropathological findings in these cases are similar to those seen in heroin-associated deaths. Anne Roussin, As for codeine, dihydrocodeineand tramadol, variability in pharmacogenetics in relation with metabolism and transport through membranes could also for developing abuse and addiction to other drugs.

Based on of the few experimental studies performed Dihydrocodeine vs codeine a clinical setting, a large variability of this potential is expected in CYP2D6 extensive metabolizers, not only for weak opioid analgesics but also for stronger ones. For instance, hydrocodone and oxycodone also produce O -demethylated metabolites with higher affinity for mu-opioid receptors. However, both experimental studies in CYP2D6 ultrarapid metabolizers and clinical studies investigating the role of the polymorphisms of drug transport proteins in the potential for abuse and addiction are lacking.

Studies on the role of these polymorphisms could also be performed using a pharmacoepidemiological approach.

However, as evidenced in this chapter, of observational studies should take into the level of population exposure to the studied drugs. Morphine, diamorphine, dihydrocodeinehydrocodone, and fentanyl are examples of opioid drugs. Derived from the opium poppy, morphine and its derivatives work by binding to opioid receptors in the central nervous system CNS to reduce pain. Newer synthetic opioid drugs, for example, tramadol and hydrocodone, may have additional effects on serotonin and norepinephrine levels.

Opioid drugs may reduce the ability to concentrate as well as reduce pain. The respiratory and cough centers are also depressed by morphine, as is the neurotransmitter acetylcholine. Codeine, a common but milder narcotic, is also derived from the opium poppy Martin Codeine is used to suppress dry coughs as well as for the relief of general pain. Opioids are potentially addictive. Major side effects of opioids are constipation, nausea, and dry mouth. Adding other analgesics, such as paracetamol, nonsteroidal antiinflammatory drugs NSAIDsor cyclooxygenase-2 COX-2 inhibitors to patient-controlled analgesia PCA reduced the amount of morphine the patient used ificantly McDaid et al Continued use may lead to tolerance, dependence, or addiction.

A variety of complications following parenteral self-administration of oral methadone were noted, including regional thrombosis, often associated with shock and multiorgan failure [ 31 ]. He had an extensive anterior myocardial infarction as a result of occlusion of the left anterior descending coronary artery, which was reopened by percutaneous transluminal coronary angioplasty.

This case presents circumstantial evidence only, and the association was probably not a true one. Methadone-induced long QT syndrome associated with torsade de pointes, can be effectively managed by the use of implantable cardioverter defibrillators, as has been shown in eight patients on methadone maintenance [ 33 ]. In Dihydrocodeine vs codeine year-old woman torsade de pointes after an increase in daily methadone dose to mg for heroin addiction was treated with cardioversion and infusions of magnesium sulfate and lidocaine [ 34 ].

Pulseless polymorphic ventricular tachycardia was reversed by cardiopulmonary resuscitation. She was not taking other medications that would have increased the serum methadone concentration. In the last case, the authors suggested that withdrawal of the protease inhibitors had led to deinduction of metabolism of methadone and increased its blood concentration. In a cross-sectional study in heroin addicts there was an association between methadone dosage Dihydrocodeine vs codeine QT interval [ 37 ].

There was no association between buprenorphine treatment and QT interval. QT interval prolongation was also found in a neonate born to a mother taking methadone [ 38 ]. Bradycardia, tachycardia, or an irregular heart rate in neonates should increase the suspicion of the possibility of QT interval prolongation. QT interval prolongation and torsade de pointes can occur after intravenous or high-dose methadone. There is a linear relation between QT interval prolongation and the dose of methadone [ 39 ].

It is prudent to avoid concomitant use of other drugs that prolong the QT interval. This is of ificance in individuals infected with HIV, who might have not only viral cardiomyopathies or autonomic neuropathies but also be taking macrolides, quinolones, clindamycin, trimethoprim, fluconazole, pentamidine, and other drugs that are closely associated with torsade de pointes and other cardiac dysrhythmias [ 40 ].

QT interval prolongation has been studied retrospectively in patients taking methadone maintenance and 80 controls [ 42 ]. Torsade de pointes also occurred in six patients the methadone group. The risk of QT c prolongation correlated positively with methadone dosage, hepatic impairment, potassium depletion, and the use of inhibitors of CYP3A4. In 78 patients taking methadone QT c prolongation was associated with higher doses of methadone [ 43 ]. The R -enantiomer was found to be responsible. The association between methadone treatment and QT c interval prolongation, QRS widening, and bradycardia has been explored in patients with at least a 1-year history of opioid misuse [ 44 ].

The QRS duration and heart rate Dihydrocodeine vs codeine not change. There were no cases of torsade de pointes, cardiac dysrhythmias, syncope, or sudden death. There was a positive correlation between methadone concentration and the QT c interval. A 6-month old infant who received methadone 0.

Methadone was withdrawn and 10 Dihydrocodeine vs codeine later sinus rhythm returned. Methadone-related torsade de pointes has been reported in a patient with chronic bone and vaso-occlusive pain due to sickle cell disease [ 48 ]. On day 2, he developed asymptomatic bradycardia and QT c prolongation — msec. On day 3, he developed profuse sweating and non-sustained polymorphous ventricular tachycardia consistent with torsade de pointes. He had hypokalemia and hypocalcemia. Echocardiography showed normal bilateral ventricular function, mild pulmonary hypertension, and trivial four-valve regurgitation.

This case highlights the importance of Dihydrocodeine vs codeine careful monitoring, especially when prescribing such large doses of methadone. The effects of methadone on cardiac function are potentially fatal. Another report has highlighted the potential risks of combining prodysrhythmic drugs on cardiovascular function [ 49 ]. The QT interval and heart rate normalized after withdrawal of all treatment. In this case it is likely that the myocardial repolarization potential of methadone and doxepin may have been influenced or triggered by bradycardia induced by metoprolol.

This shows the importance of cardiac monitoring in patients receiving combination therapy with potential adverse cardiac effects. Patients with co-morbidities are at high risk. She was also taking fluoxetine and intravenous cocaine, which can prolong the QT interval, Dihydrocodeine vs codeine fluoxetine and marijuana, which inhibit the activity of CYP3A4, which is responsible for the metabolism of LAAM and its active metabolite.

In a retrospective case study in methadone maintenance treatment programs in the USA and a pain management center in Canada, 17 methadone-treated patients developed torsade de pointes during 5 years [ 52 ]. Six patients had had an increase in methadone dose in the months just before the onset of torsade de pointes.

One patient had taken nelfinavir, a potent inhibitor of CYP3A4, begun just before the development of torsade de pointes. The above two susceptibility factors increased drug dosage and drug interactions are important when eliciting the cause of torsade de pointes in patients taking methadone. Tjorvi E. Perry, Charles D. Collard, in Pharmacology and Physiology for Anesthesia Weaker opioids, including codeine, dihydrocodeinetramadol, hydrocodone, and oxycodone, are metabolized to more potent opioids such as morphine, hydromorphone, and oxymorphone largely by the CYP enzyme CYP2D6.

For example, 0. Studies have shown a ificantly lower plasma M1 concentration and reduced analgesic effects of tramadol in poor metabolizers compared with extensive metabolizers. ificant differences in the time course of plasma concentrations of oxycodone metabolites occur depending on the CYP2D6 genotype. Individuals with a CYP2D6 polymorphism that in CYP2D6 deficiency have lower oxymorphone levels compared with individuals with genotypes associated with Dihydrocodeine vs codeine normal or ultrarapid metabolism.

Of subjects genotyped in one study, were extensive metabolizers metabolized at a normal rate18 patients were poor metabolizers, and 10 were ultrarapid metabolizers, with ificant differences in methadone concentrations between groups. While metabolism of alfentanil, fentanyl, and sufentanil can be affected by CYP3A4 activity, CYP3A4 gene polymorphisms have not been associated with differences in clinical effects for these opioids.
