In reference 68, a different approach was used to verify the robustness of a CE separation of ibuprofen, codeine phosphate, degradation products, and impurities in a drug product (tablet). Small variations around the optimal conditions obtained during method optimization were introduced and the results were predicted from the response model. The variations in the factor levels during the robustness evaluation were smaller than those evaluated during method optimization. Since both migration times and resolutions were acceptably predicted, the method was considered robust with respect to the small changes. The examined factors...

An MEKC method for the determination of ibuprofen, codeine phosphate hemihydrate, their nine potential degradation products, and impurities in a commercial tablet formulation was developed, optimized, and fully validated according to ICH guidelines and submitted to the regulatory authorities. The optimized system containing ACN as organic modifier allowed baseline separation of ibuprofen, codeine, and nine related substances within 12 min.

Other examples of analgesics or their metabolites that have been found in the environment include 4-aminoantiyrine, aminophenazone, codeine, fenoprofen, hydrocodone, indometacine, ketoprofen, mefenamic acid, naproxen, propyphenazone diclofenac, ibuprofen, phenazone, gentisic acid and N-methylphenacetin. Many studies have identified these compounds in various locations around the world and in different water resources (e.g., Heberer et al. 1997, 2001a, 2001b Ternes 2001 Stumpf et al. 1999 Ahrer et al. 2001 Sedlak and Pinkston 2001 Holm et al. 1995 Ahel and Jelicic 2001 Sacher et al. 2001).

On the x axis are respective PPCPs that are primarily cosmetics (1 = HHCB, 2 = AHTN, 3 = acetophenone, 4 = camphor, 5 = isobomeol, 6 = skatol, 7 = celestolide, i.e., AHMI, 8 = Phantolide, i.e., AHMI), the lotion ingredient (9 = methyl salicylate), two disinfectants (10 = triclosan and 11 = trilocarban), antihypertensive (12 = dehydronifedipine, 13 = diltiazem, 14 = bezafibrate, and 15 = gemfibrozil), analgesics and anti-inflammatories (16 = naproxen, 17 = ibuprofen, 18 = codeine), antimicrobials (19 = chlortetracycline, 20 = erythromycin, 21 = novobiocin, 22 = oxytetracycline, 23 = sulfamethaxazole, 24 = thiabendazole, 25 = trimethoprim), anxiolytic sedative (26 = carbamazepine), antidiabetic (27 = metaformin), reproductive (28 = 17(3 estradiol, 29 = 17a-ethinyl estradiol), GIT (30 = cimetidine, 31 = ranitidine), and respiratory (32 = Albuterol). The concentrations were compiled from Boyd et al. (2003), Gagne et al. (2006), Glassmeyer et al. (2005), Halden and Pauli (2005), Huang and Sedlak (2001), Ricking et al. (2003), and Temes et al. (2003).

Codeine is a natural alkaloid found in the opium plant. As a pharmaceutical, codeine is used as an analgesic, antitussive, and antidiar-rheal. Codeine is also commonly combined with other cough suppressants as well as with aspirin and ibuprofen. In the United States, codeine is a Schedule III controlled substance, which means that its distribution is more tightly regulated than unscheduled drugs. Codeine has pain-relieving qualities principally because, once in the body, about 10 percent of codeine turns into morphine. This conversion occurs in the liver, where an enzyme changes codeine s... 

Hydrocodone is a semisynthetic opioid derived from codeine.18It is utilized as an analgesic and antitussive available for oral administration, often in combination with acetaminophen or ibuprofen. As a rule, potent analgesics containing a methoxyl group at position 3 (e.g., hydrocodone, K, = 19.8 nM) bind the mu receptor relatively weakly, but their O-demethylated metabolites (such as hydromorphone, Kt = 0.6 nM) bind more strangely. As with oxycodone, the possibility exists that some of their ability to relieve pain may actually derive from their active metabolites 48... 

Since most codeine is dispensed as part of a compound preparation, potential side effects of the other drug(s) must also be considered. For instance, someone with stomach ulcers should not take codeine that is combined with a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin or ibuprofen. Another type of risk from a compound preparation relates to codeine abuse. For instance, a person who abuses codeine might routinely take a dose of 100-200 mg of codeine to produce noticeable euphoria. Using Tylenol 3 to obtain this dose would also mean ingesting 1,000-2,000 mg of acetaminophen. Taking that amount of acetaminophen for any extended period presents a risk for liver damage, especially in combination with alcohol. 

Even if we cannot yet cure arthritis, there are things we can do to alleviate its symptoms. Simple painkillers such as paracetamol, ibupro-fen and codeine can be taken, and the combination of ibuprofen with a little codeine is particularly effective, a tablet will give relief for up to 6 hours. When such painkillers are no longer strong enough, then a... 

This chapter concentrates on some drug choices in acute rather than chronic pain, but the same principles can be used to determine the appropriateness of other types of analgesic. The drugs considered in this section are paracetamol, non-steroidal anti-inflammatories (NSAIDs specifically diclofenac, ibuprofen, indometacin, naproxen, sulindac and tenoxicam) and opioids (codeine, dihydrocodeine, morphine, pethidine and tramadol). Unless otherwise stated, all pharmacokinetic data originate from standard reference sources [1-5] and apply to adults only.

Oxycodone is a codeine congener that appears to be 10 to 12 times more potent than codeine. When taken orally, oxycodone is as potent as parenteral morphine, and, like codeine, oxycodone retains most of its parenteral potency when given orally. When compared with codeine, morphine, or pentazocine, oxycodone may also have a lower incidence of side effects, but it produces euphoria and thus has potential for abuse. Oxycodone is commercially available in combination with acetaminophen, aspirin, or ibuprofen (see Table 7-7)... 

Hydrocodone, another codeine congener, is approximately six times more potent than codeine. This agent appears to cause less constipation and less sedation than codeine. It has been suggested that hydrocodone may produce more euphoria than codeine, but this effect has not been substantiated in clinical studies. Hydrocodone is also available in combination with aspirin, acetaminophen, or ibuprofen.

Codeine is combined with aspirin, paracetamol and ibuprofen in many OTC analgesic products, and also in the formulary preparations co-codamol (with paracetamol) and co-codaprin (with aspirin). Dihydrocodeine is included with paracetamol in one OTC product, and at a higher dose in co-dydramol tablets, which are prescription-only medicines (POM). 

Migraine can often be treated with paracetamol, ibuprofen or aspirin alone, or with combination products containing them. There are also some non-prescription medicines specifically licensed for the treatment of migraine. One such is a coformulation of paracetamol, codeine and the antihistamine buclizine, included for its antiemetic action. Other specific migraine treatments are reviewed below. 

Analgesic preparations are all based on one of three drugs - aspirin, paracetamol and ibuprofen - sometimes in combination with the ancillary analgesics codeine or dihydrocodeine, or with other constituents that are claimed to increase effectiveness. (Author s note please check and amend at proof stage An application has been made for P classification for naproxen for PD, and it may be reclassified before the book is published.)... 

There are also several proprietary preparations combining paracetamol or ibuprofen with codeine, and a paracetamol/dihydrocodeine combination (nonproprietary co-dydramol tablets contain a higher dose of dihydrocodeine and are prescription-only (POM)).
