Dextropropoxyphene is an analgesic in the opioid category. It is used to treat mild to moderate agony and as an antitussive. It can be used to ease stomach-ache before, during and after an operation. It is commonly combined with acetaminophen within the preparation co-proxamol (Darvocet in the US and CAPADEX contained by AUS).
It is an optical isomer of Levopropoxyphene. The racemic mixture is called Propoxyphene.
Some preparations that contain dextropoxyphene include: Distalgesic and Doloxene.
Indications
[edit] Analgesia
Dextropropoxyphene, approaching codeine, is a "weak" opioid. Codeine is more commonly used, however some individuals (approximately 10-20% of the Caucasian population) are unable to metabolize it, due to poor functioning of the enzyme CYP2D6. It is within these people that dextropropoxyphene is especially useful, as its metabolism does not require CYP2D6.
[edit] Opioid renunciation
In pure form, dextropropoxyphene is commonly used to ease the deduction symptoms in individuals addicted to opioids. Being very shaky in comparison to the opioids that are commonly abused, dextropropoxyphene can merely act as a "partial" substitute. It does not hold much effect on mental cravings; however it can be effective contained by alleviating physical withdrawal effects, such as muscle cramps.
Dextropropoxyphene is subject to some controversy: while plentiful physicians prescribe it for a wide extent of mildly to moderately painful symptoms as all right as for treatment of diarrhoea, many others decline to prescribe it, citing its highly addictive temper and limited usefulness (some studies show it to be no more effective as a palliative than aspirin).
The therapeutic index of dextroproxyphene is relatively small. In the UK, dextropropoxyphene and co-proxamol are in a minute discouraged from general use; and, since 2004, preparations containing just dextropropoxyphene have be discontinued. This has be a somewhat controversial decision, since it have caused abusers to switch to the combined product and risk acetaminophen toxicity. Australia decline to follow suit and opted to allow pure dextropropoxyphene to remain available by prescription.
In the United States, dextropropoxyphene HCl is available as a prescription formulation beside acetaminophen in ratio anywhere from 30mg / 600mg to 60mg / 325mg, respectively. These are usually name "Darvocet." On the other hand, "Darvon" is a pure Propoxyphene preparation available surrounded by the U.S. that does not contain acetaminophen. In Australia, dextropropoxyphene is available on prescription, both as a combined product (32.5mg dextropropoxyphene per 325mg acetaminophen) known as any "Di-gesic", "Capadex", or "Paradex," and in pure form (100mg capsules) set as "Doloxene".
[edit] Adverse effects
Darvocet overdose is commonly broken into two categories: liver toxicity (from acetaminophen poisoning) and dextropropoxyphene overdose. Many users experience toxic effects from the acetaminophen contained by pursuit of the endlessly-increasing dose required to achieve euphoria. They suffer acute liver toxicity, which cause severe stomach pain, nausea, and vomiting (all of which are increased by muted or stimulation of the sense of sight).
Dextropropoxyphene also has several other non-opioid side-effects.
Both propoxyphene and its metabolite norpropoxyphene, hold local anesthetic effects at concentrations about 10 times those crucial for opioid effects. In this respect, norpropoxyphene is more potent than propoxyphene, and they are both more potent than lidocaine.[1]
Both propoxyphene and norpropoxyphene also have direct cardiac effects which include decrease heart rate, decreased contractility, and decrease electrical conductivity (ie, increased PR, AH, HV, and QRS intervals). Norpropoxyphene is several times more potent than propoxyphene in this pursuit. These effects appear to be due to their local anesthetic activity and are not reversed by naloxone.[1][2][3]
Both propoxyphene and norpropoxyphene are potent blockers of cardiac membrane sodium channel and are more potent than lidocaine, quinidine, and procainamide in this respect.[4]
They (propoxyphene and nor-propoxyphene) appear to enjoy the characteristics of a Vaughn Williams Class IC antiarrhythmic.
[edit] Toxicologic Mechanism
A) Excessive opioid receptor stimulation is responsible for the CNS depression, respiratory depression, miosis, and gastrointestional effects seen within propoxyphene poisoning. It may also account for mood/thought altering effects.
B) Local anesthetic pursuit appears to be responsible for the arrhythmias and cardiovascular depression seen within propoxyphene poisoning.[3] Widening of the QRS complex appears to be a result of a quinidine-like effect of propoxyphene, and sodium bicarbonate therapy appears to own a positive direct effect on the QRS dysrhythmia.[5]
C) Seizures may result from either opioid or local anesthetic effects.[1]
D) Pulmonary edema may result from direct pulmonary toxicity, neurogenic/anoxic effects, or cardiovascular depression.[3]
[edit] Recreational use
Recreational users tend to lift anywhere from 240 to 420 milligrams of dextropropoxyphene (and the acetaminophen that goes near it). These users often suffer a demanding dry mouth, decreased appetite, urinary retention and constipation that may front to diverticulitis.
Dextropropoxyphene Hydrochloride is also used in the so-called "Darvon cocktail".
