A 3-year-old White child was admitted to the critical care unit in a coma after a generalized convulsion. Codeine and salicylic acid were present in his plasma. The possible aetiology and management are discussed.
OBJECTIVE
To describe an adverse effect with intravenous codeine in a chid diagnosed with sickle cell anemia.
METHODS
A seven-year-old boy with sickle cell anemia was admitted to the emergency department with severe pain unresponsive to high doses of oral acetaminophen; subsequently, intravenous
OBJECTIVE
To report a case of seizure activity associated with oral codeine phosphate administered for analgesia in an elderly woman with end-stage renal disease.
METHODS
A 73-year-old Taiwanese woman with end-stage renal disease received oral codeine phosphate 30 mg 4 times daily for her back and
BACKGROUND
Bupropion hydrochloride (Zyban) is prescribed for smoking cessation. It is contraindicated in patients with seizure disorders. We report three patients with generalized tonic-clonic seizure that occurred a few days after the intake of this drug.
METHODS
The first two patients had no
Tramadol is a widely prescribed analgesic that influences both opioid and monoamine neurotransmission. While seizures have been reported with its use, the risk in clinical practice has not been well characterised. We examined risk of seizure with tramadol relative to codeine, a Opiates are known for their stereospecificity. The following studies show that l-codeine was active in the mouse tail-flick test as well as in the hot plate test whether given p.o. or s.c. The ED50 in the first test was 4.09 mg/kg s.c. (2.01-8.34 mg/ kg) and 13.41 mg/kg p.o. (6.91-26.0 mg/kg). In
The case histories are presented of 6 patients with accidental poisoning by Spasmoplus suppositories. The main toxic constituents are codeine and the pyrazolone derivative, propyphenazone. All patients had symptoms of codeine intoxication with somnolence, miosis and oedema, 2 patients had also
Exogenously administered morphine can have both convulsive or anticonvulsive effects, depending on the dose and species. The levels of the endogenous opiate alkaloids morphine and codeine were significantly elevated in specific rat brain regions by the convulsive drug, pentylenetetrazole, as well as
Morphine-6-sulfate (M6S) and codeine-6-sulfate (C6S) are mu-selective opiates which have been isolated from brain. M6S is an effective analgesic, with a 30-fold greater potency than morphine in the mouse radiant heat tailflick assay and similar to the active morphine metabolite
After a series of seven electroconvulsive shocks, mice (C57BL/6J) showed a marked change in their response to opiates. Although very large doses of mu agonists induce convulsions in normal control mice, our evidence indicated that this was accomplished through nonopiate mechanisms: they could not be
A simple and rapid method for the analysis of heroin seizures by micellar electrokinetic chromatography with short-end injection is described. Separations were performed using an uncoated fused silica capillary, 50 cm x 50 microm I.D. x 360 microm O.D. with an effective separation length of 8 cm.
BACKGROUND
Tramadol hydrochloride is a novel, centrally acting analgesic with two complementary mechanisms of action: opioid and aminergic. First marketed in 1994, tramadol is frequently prescribed by physicians for the management of moderate-to-moderately severe chronic pain. The author evaluates
Tramadol is one of the most widely used centrally acting analgesics worldwide. Because of its multimodal analgesic mechanism (opioid plus nonopioid), the adverse effects profile of tramadol, similar to its analgesic profile, can be atypical compared with single-mechanism opioid analgesics. The
So-called weak opioid analgesics are often used to treat severe pain, or when paracetamol or a nonsteroidal anti-inflammatory drug (NSAID) proves inadequate. But are weak opioids any more effective than paracetamol or NSAIDs on nociceptive pain, and are they better tolerated than morphine? To answer
