Topiramate Topamax ; in Bipolar Disorder Topiramate Topamax ; is an antiepileptic agent approved for use in Canada since 1997 for adjunctive therapy in patients with refractory partial seizures. Preliminary observations indicate that topiramate may have antimanic or anticycling effects in some patients with bipolar disorder, and may be associated with appetite suppression and weight loss. This newsletter reviews topiramate's pharmacology, pharmacokinetics, and adverse effects as well as summarizes published clinical studies with topiramate in bipolar disorder. Pharmacology Topiramate is a structurally unique anticonvulsant, derived from d-fructose. Although topiramate's antiepileptic mechanism of action is not yet fully understood, several mechanisms have been proposed. These mechanisms of action are similar to those of established antiepileptic drugs, especially the mood stabilizers carbamazepine, valproic acid, and lamotrigine. These include: 1. GABA receptor agonism at nonbenzodiazepine receptor sites, 2. Sodium channel antagonism, resulting in decreased sodium conductance and frequency of action potentials 3. Calcium channel antagonism, modulating Land N-type calcium channel activity, and 4. Glutamate receptor antagonism at nonNDMA receptors. In addition, topiramate possesses weak carbonic anhydrase inhibiting properties. Pharmacokinetics Topiramate is well absorbed, with an oral bioavailability of 80%, and readily crosses the blood brain barrier. The rate of absorption is slightly decreased in the presence of food, but the extent of absorption remains unchanged. As such, topiramate can be administered without regard to food. Volume of distribution ranges from 0.6-0.8L kg and it is excreted unchanged in the urine. Elimination half-life is approximately 21 hours, with a twice-daily dosage recommendation. Furthermore, topiramate exhibits predictable linear pharmacokinetics with minimal plasma protein binding ~15% ; and has a high therapeutic index. Drug Interactions Only a small fraction of topiramate is metabolized in the liver ~20% ; . Topiramate plasma concentrations are reduced by 40 to 50% when co-administered with carbamazepine and phenytoin. Addition of topiramate in patients with plasma phenytoin concentrations above the therapeutic range may increase phenytoin concentrations by approximately 25%. Concomitant use of digoxin has resulted in reduced serum digoxin concentrations ~15% ; . Close monitoring for worsening of clinical symptoms is warranted when topiramate is started in a patient already stabilized on digoxin therapy. Topiramate decreases serum concentrations of ethinyl estradiol by ~30%, therefore oral contraceptives containing at least 50mcg of estrogen should be used. To.
No Yes If she is taking phenytoin, carbamazepine, barbiturate, topiramate, oxycarbamazepine, or primidone for seizures or rifampin, griseofulvin, aminoglutethamide or St. John's Wort, provide condoms or spermicide or help her choose another method that is more effective, such as DMPA. Use of valproic acid does NOT lower the effectiveness of POPs. Discuss ECPs.

This study was supported by the University of Ulm Medical School Research Foundation and the Pharmacia & Upjohn Company, Erlangen, Germany.

Tel 01992 457272, fax 01992 451075. See SPC for further details. Zomig nasal spray Zomig zolmitriptan ; 50mg ml nasal spray has been launched AstraZeneca ; . The spray delivers a dose of 5mg and one unit dose should be sprayed into one nostril only. If a second dose is required, it should not be administed within 2 hours of the initial dose. After oral administration peak plasma concentrations are seen 1-2 hours after dosing. Mean Cmax values range from about 10 ng ml after an oral dose of 0.5 mg to 7800 ng ml for the 400 mg dose. No absolute bioavailability study has been reported. Plasma protein binding is about 55-65%. The volume of distribution divided by the extent of bioavailability V F ; is approximately 200-300 l. Elimination half-life is approximately 8-12 hours. The apparent oral ; clearance is about 16-20 l h. Olopatadine is metabolised only to a minor degree. Two metabolites have been identified in the urine: N-desmethyl and N-oxide metabolite. About 70% of unchanged olopatadine is excreted in the urine within 48 hours after oral administration of 10 mg olopatadine. With regard to dose-concentration linearity, Cmax and AUC values appear to increase in a dose-proportional manner in studies. The elimination half-life is moderately higher at steady-state than after single dose. Elderly subjects and patients with impaired renal function have higher 3-fold ; exposure after oral olopatadine than healthy young subjects. Following topical ocular administration in man, olopatadine was shown to have low systemic exposure. Two studies in normal volunteers totalling 24 subjects ; dosed bilaterally with olopatadine 0.15% ophthalmic solution once every 12 hours for 2 weeks demonstrated plasma concentrations to be generally below the quantitation limit of the assay 0.5 ng ml and ativan, for instance, what is valproic acid.

Implications For Patients With Underlying Liver Disease Drug-induced liver disease DILD ; has always held an important place in the field of hepatology, as more than 600 drugs and chemicals are known to cause varying degrees of hepatic injury. Recently, however, following the withdrawal of trogIitazone Rezulin ; and Bromfenac Duract ; because of associated instances of fatal fulminant hepatic failure, increased attention has been focused on the risks of DILD. Hepatotoxicity is the leading reason why drugs are withdrawn from development and from the market and why they fail to win approval according to Dr. Robert Temple of the FDA. As many as 9% of all adverse drug reactions are related to toxic effects on the liver and acetaminophen and other drugs currently account for half of the estimated 2000 cases of fulminant hepatic failure that occur annually in the U.S., far more than acute viral hepatitis or other causes. Drugs can affect the liver in several different ways and in doing so can produce a wide spectrum of injury patterns. Drugs can mimic acute viral hepatitis e.g., Isoniazid, Diclofenac ; , gallstone obstruction e.g., Augmentin, Erythromycin Estolate ; , acute fatty liver syndromes e.g., Intravenous Tetracycline, Vallroic Acid ; , as well as chronic hepatitis, granulomatous hepatitis, primary biliary cirrhosis-like injury, and they can even cause neoplastic lesions including adenomas and hepatic malignancy. Most drugs causing liver injury do so very rarely, either acting through a reactive metabolite or via an immuno allergic mechanism, the latter often being accompanied by fever, rash, eosinophilia. and other systemic manifestations. Drugs such as acetaminophen are predictable, dose-related hepatotoxins. The safe use of drugs not directed at treating hepatitis or other hepatic disorder in patients with underlying chronic liver disease is an important yet controversial area, since few drugs have been formally studied in patients with cirrhosis or other impaired liver conditions. With a significant proportion of the general population infected with chronic hepatitis B or chronic hepatitis C, or having underlying fatty liver disease or alcoholic liver disease, what, if any, risk of worsening their underlying liver condition may occur with commonly used medications to treat diabetes, hypercholesterolemia, heart disease, etc., is a question that has become increasingly asked. For patients with underlying liver disease, it is recommended that certain medications be avoided methotrexate, niacin ; or closely monitored for toxicity. These recommendations often do not address several important specific issues such as the degree of liver impairment and other important aspects of the underlying liver disease. In general, most drugs can be taken by patients with underlying liver disease without an increased risk of hepatotoxicity. There are some notable exceptions, including antiretroviral therapies and antituberculosis drugs taken by patients with underlying chronic hepatitis B or C. For agents the risk of hepatic injury is much harder to quantify. Drugs such as the HMG CoA reductase inhibitors statins ; , tamoxifen, and the thiazolidione agents for the treatment of diabetes contain warnings against using them in patients with liver disease. These agents certainly have been used in liver disease patients when indicated, although close liver enzyme and clinical monitoring is advised in that setting. In order to reduce the risk of serious. hepatic injury, many drugs come with recommendations and guidelines to monitor hepatic enzymes usually ALT levels ; . Several agents are associated with mild elevations in AST and ALT that either do not progress or may even resolve while the drug is being taken. For patients who develop increas ing hepatic enzymes, stopping the drug if the ALT rises above three to five times the upper limit of normal is felt to prevent development of more serious and even fulminant hepatic injury. Just how compliant physicians and their patients are with the requirements for liver enzyme monitoring is an area of controversy. Monitoring for clinical symptoms is appropriate for drugs that act through allergic or hypersensitivity mechanisms since these features of fever, rash, etc., usually announces the toxicity. However, stopping a medication once these immuno allergic symptoms have developed does not guarantee that the hepatic injury will resolve. For over-the-counter agents such as acetaminophen, warnings about the potential role of alcohol in causing liver injury are provided, but other than suggesting patients consult with their physicians if they are consuming three or more alcoholic beverages daily, few specifics are provided about this potential interaction. I tell patients not to exceed two grams of acetaminophen daily if they regularly consume alcohol, although many aspects of the hepatotoxic alcoholacetaminophen interaction are still poorly understood, including the true minimal dose of acetaminophen that can lead to injury and the amount of alcohol that is necessary. It is important that children take only the dose specified in the label for medications. There are several reports of unintentional overdoses and cialis.

IV. What Explains the High Frequency of Price Changes? Menu-cost models of price adjustment suggest that inflation is higher in markets where price changes are more frequent for example, Barro, 1972; and Taylor, 1999 ; . This is due, in part, to the cost of changing prices. Table 1 displays cross-correlations between various indicators for all items and danazol. Fig. 9.
