Morphine Muscle Relaxer

Monday, July 21st, 2008

Morphine is known to produce a characteristic and reproducible elevation of the tail in mice (Straub tail response). The morphine-induced Straub tail response in mice has been used to evaluate skeletal muscle relaxant (SMR) activity of compounds administered intraperitoneally (i.p.). This model was used to evaluate the oral (p.o.) efficacy of a number of SMRs and other pharmacological agents. Male mice (n 5) were given test drugs p.o. followed by morphine sulfate [15 mg/kg subcutaneously (s.c.)] 15 min later. The mice were scored all or none for a Straub tail reaction 45 min later.

Graded doses of active compounds were further evaluated for ED50 estimation by probit analysis. ED50 values (mg/kg) were estimated for the following compounds: baclofen (6.4), chlorpromazine HCl (3.8), cyclobenzaprine HCl (24.6), dantrolene Na (14.4), diazepam (8.3), haloperidol (6.2), naloxone HCl (8.7), phenoxybenzamine HCl (47.6), phentolamine HCl (265), and trifluoperazine HCl (25.4). These ED50 values appeared to correlate with initial adult human daily oral doses for muscle relaxation.

The following compounds inhibited the Straub tail response in 40% of the mice tested at the doses indicated (mg/kg): carisoprodol (300), lidocaine (100), mephenesin (300), phenytoin (100), procainamide HCl (100), procaine HCl (100), propranolol HCl (100), quinidine sulfate (100); and all selected calcium-channel blockers (30), antidepressants (30), and neuromuscular blocking agents (> 10 times the literature i.p. ED50 values with the exception of gallamine triethiodide at 30 mg/kg) that were tested. Pentobarbital Na was active only at doses that impaired the righting reflex. This animal model was thus determined to be useful for evaluating SMR efficacy and in predicting.

Types of Pain Pills

Wednesday, July 9th, 2008

Painkillers can be divided into two groups, non narcotic analgesics which can be purchased over the counter such as aspirin, acetaminophen, Tylenol, and small doses of codeine and narcotic analgesics which require a prescription for example morphine and high doses of codeine. Analgesic is the medical name for painkillers.

Painkillers give a feeling of euphoria and, just like heroin or opium, carry a high risk for abuse and recreational use. Painkillers reduce pain in different ways, depending on the class they belong to some target the site of pain while others reduce the sensation of pain. Painkillers can cause side effects in some people; aspirin and non steroidal anti-inflammatories like naprosyn and ibuprofen cause stomach bleeding and paracetamol can cause liver damage if you take too many tablets.

Painkillers can also be given by injection or by infusion, as a continuous dose given through a small tube into a vein or a fine needle placed just under the skin. Painkillers are unlikely to have any effect on depression but can help with headaches or other pains that accompany depression. Some combination painkillers can be bought over the counter and contain smaller quantities of opioid painkiller than those available on prescription.

The strongest painkillers used for controlling cancer pain are called opioids. The effective chemicals in prescription painkillers called opioids are derived from the same poppy plant used to make opium and heroin. If you are taking painkillers to control pain, it is very, very important that you take them regularly as prescribed by your doctor. Children born to mothers who abuse painkillers are also subjected to withdrawal symptoms, stunted growth, learning disabilities and life long health problems.

It is not illegal to use painkillers. However, according to the Narcotic Control Act, it is illegal to obtain prescribed painkillers without an authorized prescription. Dependency on prescription painkillers often starts with a common injury, surgery or condition: You experience frequent pain or discomfort. Broadly speaking painkillers fall into three classes: paracetamol non steroidal antiinflammatory drugs, which include aspirin and ibuprofen opioids or narcotics, including codeine.

Some painkiller differences are as follows: Paracetamol: Painkiller, used to bring down temperature. Aspirin: Anti inflammatory, reduces temperature, can cause gastric irritation, should not be given to under 16s Ibuprofen: Similar to aspirin but fewer side effects And while 89% of people knew painkillers can be unsuitable for individuals with medical conditions, more than 40% did not know which ones could pose a danger.

Flexeril Morphine

Tuesday, July 8th, 2008

Question: Hello, I have been clean and sober for 7 1/2 years. I have just came up positive for Morphine. And the only thing I’ve taken is a couple of Flexeril for lower back pain, could this have that effect on the test? And also what about Poppy seed bagel’s, some one told me that depending on your own body chemistry that could also produce that result.?.

Answer: Flexeril is not a narcotic and should not come up as morphine. Nor do poppy seeds. The structure of Flexeril is most like the tricyclic antidepressants.

Question: What is Flexeril and what is it used for?

Answer: Flexeril is a muscle relaxant used mainly in patients with back spasm, but occasionally in spasm following trauma.
