These drugs include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics and isoniazid.
Or disopyramide. Patients should be carefully monitored if SPORANOX is coadministered with either of these drugs. Anticonvulsants: Reduced plasma concentrations of itraconazole were reported when SPORANOX was administered concomitantly with phenytoin. Carbamazepine, phenobarbital, and phenytoin are all inducers of CYP3A4. Although interactions with carbamazepine and phenobarbital have not been studied, concomitant administration of SPORANOX and these drugs would be expected to result in decreased plasma concentrations of itraconazole. In addition, in vivo studies have demonstrated an increase in plasma carbamazepine concentrations in subjects concomitantly receiving ketoconazole. Although there are no data regarding the effect of itraconazole on carbamazepine metabolism, because of the similarities between ketoconazole and itraconazole, concomitant administration of SPORANOX and carbamazepine may inhibit the metabolism of carbamazepine. Antimycobacterials: Drug interaction studies have demonstrated that plasma concentrations of azole antifungal agents and their metabolites, including itraconazole and hydroxy-itraconazole, were significantly decreased when these agents were given concomitantly with rifabutin or rifampin. In vivo data suggest that rifabutin is metabolized in part by CYP3A4. SPORANOX may inhibit the metabolism of rifabutin. Although no formal study data are available for isoniazid, similar effects should be anticipated. Therefore, the efficacy of SPORANOX could be substantially reduced if given concomitantly with one of these agents. Coadministration is not recommended. Antineoplastics: SPORANOX may inhibit the metabolism of busulfan, docetaxel, and vinca alkaloids. Antipsychotics: Pimozide is known to prolong the QT interval and is partially metabolized by CYP3A4. Coadministration of pimozide with SPORANOX could result in serious cardiovascular events. Therefore, concomitant administration of SPORANOX and pimozide is contraindicated see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS ; . Benzodiazepines: Concomitant administration of SPORANOX and alprazolam, diazepam, oral midazolam, or triazolam could lead to increased plasma concentrations of these benzodiazepines. Increased plasma concentrations could potentiate and prolong hypnotic and sedative effects. Concomitant administration of SPORANOX and oral midazolam or triazolam is contraindicated see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS ; . If midazolam is administered parenterally, special precaution and patient monitoring is required since the sedative effect may be prolonged. Calcium Channel Blockers: Edema has been reported in patients concomitantly receiving SPORANOX and dihydropyridine calcium channel blockers. Appropriate dosage adjustment may be necessary. Calcium channel blockers can have a negative inotropic effect which may be additive to those of itraconazole; itraconazole can inhibit the metabolism of calcium channel blockers such as dihydropyridines e.g., nifedipine and felodipine ; and verapamil. Therefore, caution should be used when coadministering itraconazole and calcium channel blockers due to an increased risk of CHF see WARNINGS AND PRECAUTIONS and ADVERSE REACTIONS, Post-Market Adverse Drug Reactions for more information.
Act, a branded drug manufacturer seeking to market a new drug product must first obtain FDA approval by filing a New Drug Application NDA ; . At the time the NDA is filed, the NDA filer must also provide the FDA with certain categories of information regarding patents that cover the dmg that is the subject of its NDA.- * " * Upon receipt of the patent information, the FDA is required to list it in an agency publication entitled Approved Drug Products with Therapeutic Equivalence, commonly known as the Orange Book.''' One stated purpose of the Hatch-Waxman amendments is to "make available more low cost generic drugs." The concern that prompted the amendments was that the FDA"s lengthy drug approval process was unduly delaying market entry by low-cost generic versions of brand-name prescription drugs. Because a generic drug manufacturer was required to obtain FDA approval before selling its product, and could not begin the approval process until any conflicting patents on the relevant branded product expired, the FDA approval process essentially functioned to extend the term of the branded manufacturer's patent monopoly. To correct this problem. Congress enacted a compromise: an expedited FDA approval process 3- Drug Price Competition and Patent Restoration Act of 1984, Pub. L.

Reaction conditions: drugs were mixed with the enzyme in cleavage buffer containing 0.5 mM ATP and incubated on ice for 10 min; 10 l of the enzyme solutions were mixed with 10 l DNA in the same buffer and further incubated for 8 min at 37; the reactions were terminated by SDS. Positions of RLX, SC, NC, and PRLX are indicated and valsartan. An apparent concentration-related suppression of CYP2C9 activity was observed in human hepatocytes after exposure to modafinil in vitro suggesting that there is a potential for a metabolic interaction between modafinil and the substrates of this enzyme e.g., S-warfarin, phenytoin ; . However, in an interaction study in healthy. Tagamet apparently through an effect on certain microsomal enzyme systems, has been reported to reduce the hepatic metabolism of warfarin-type anticoagulants, phenytoin, propranolol, chlordiazepoxide, diazepam, lignocaine, nifedipine and theophylline; thereby delaying elimination and increasing blood levels of these medicines and nevirapine. Pharmacokinetic interactions In vitro studies indicate that eplerenone is not an inhibitor of CYP1A2, CYP2C19, CYP2C9, CYP2D6 or CYP3A4 isozymes. Eplerenone is not a substrate or an inhibitor of P-Glycoprotein. Digoxin: Systemic exposure AUC ; to digoxin increases by 16% 90% CI: 4% - 30% ; when coadministered with eplerenone. Caution is warranted when digoxin is dosed near the upper limit of therapeutic range. Warfarin: No clinically significant pharmacokinetic interactions have been observed with warfarin. Caution is warranted when warfarin is dosed near the upper limit of therapeutic range. CYP3A4 substrates: Results of pharmacokinetic studies with CYP3A4 probe-substrates, i.e. midazolam and cisapride, showed no significant pharmacokinetic interactions when these drugs were coadministered with eplerenone. CYP3A4 inhibitors: - Strong CYP3A4 inhibitors: Significant pharmacokinetic interactions may occur when eplerenone is coadministered with drugs that inhibit the CYP3A4 enzyme. A strong inhibitor of CYP3A4 ketoconazole 200 mg BID ; led to a 441% increase in AUC of eplerenone see section 4.3 ; . The concomitant use of eplerenone with strong CYP3A4 inhibitors such as ketoconazole, itraconazole, ritonavir, nelfinavir, clarithromycin, telithromycin and nefazadone, is contra-indicated see section 4.3 ; . - Mild to moderate CYP3A4 inhibitors: Co-administration with erythromycin, saquinavir, amiodarone, diltiazem, verapamil, and fluconazole have led to significant pharmacokinetic interactions with rank order increases in AUC ranging from 98% to 187%. Eplerenone dosing should therefore not exceed 25 mg when mild to moderate inhibitors of CYP3A4 are co-administered with eplerenone see sections 4.2 ; . CYP3A4 inducers: Co-administration of St John's Wort a strong CYP3A4 inducer ; with eplerenone caused a 30 % decrease in eplerenone AUC. A more pronounced decrease in eplerenone AUC may occur with stronger CYP3A4 inducers such as rifampicin. Due to the risk of decreased eplerenone efficacy, the concomitant use of strong CYP3A4 inducers rifampicin, carbamazepine, phenytoin, phenobarbital, St John's Wort ; with eplerenone is not recommended see section 4.4 ; . Antacids: Based on the results of a pharmacokinetic clinical study, no significant interaction is expected when antacids are coadministered with eplerenone.
Long enough to develop chronic diabetic complications with a strain on resources in managing the same. With this scenario as the background, any effort to prevent diabetes mellitus assumes significance. Type 2 diabetes develops as a continum starting with the fully compensated insulin resistance, normoglycemic and asymptomatic state and progressing to impaired glucose tolerance and later frank diabetes. The basic metabolic defect is insulin resistance, non-autoimmune mediated beta cell dysfunction leading to insulin secretory defect and increased hepatic glucose output.102, 103 Identifying the individuals at greatest risk is essential in planning preventive measures. Prevention of diabetes mellitus has several windows of opportunity. They are divided into three stages: Primary prevention : To prevent the onset of diabetes. Secondary prevention : To prevent complications of diabetes in those who are already diagnosed to have diabetes. Tertiary prevention : To limit the damage caused by diabetic complications in those who already have some degree of complications. Primary prevention is to prevent the onset of diabetes in high risk individuals Ta ble 42 ; . The aim should be to enhance insulin sensitivity by l Lifestyle Modification : This involves diet and exercise which has been shown to be beneficial in several studies.104-106 The chance of developing diabetes is reduced by atleast 50%. The family members should reduce the consumption of refined carbohydrates, fat particularly saturated fat ; and alcohol and discontinue smoking. l Insulin Sensitizers : Some small studies have shown the usefulness of sulfonylureas96 and phenformin. The results of Diabetes Prevention Program-2 and STOP trial have recently been discussed at the European Association for the Study of Diabetes EASD ; meeting held in September 2001. Intensive lifestyle modification, metformin and acarbose have been found to delay the onset of diabetes in impaired glucose tolerant individuals.108, 109 The intervention trial involving troglitazone had been discontinued. l Avoiding diabetogenic drugs such as beta blockers, steroids, phenytoin, immunosupressants, thiazide diuretics, pentamidine and dilantin. Secondary Prevention : The main objective should be to detect early and didanosine.

Principal research questions: 1 ; Is there a time trend in the incidence of non-melanoma skin cancer and does this vary with age? 2 ; What is the time to recurrence of first NMSC or occurrence of another NMSC? 3 ; What are the potential risk factors for NMSC, such as smoking and immunocompromised patients? Using the THIN the Health Improvement Network ; database, all people with a recorded diagnosis of NMSC, including basal cell carcinoma and squamous cell carcinoma, will be identified.

After S.S. was admitted to the high-risk obstetric unit, phenytoin levels in the blood were measured, and fetal monitoring was started. Her blood levels of phenytoin were subtherapeutic. In the next several days, the amount of phenytoin administered was adjusted according to blood levels and clinical status. No further seizure activity was observed, and the status of the fetus remained stable. A fetal ultrasound did not reveal any anomalies. Before discharge, S.S. received counseling about the effects that pregnancy and epilepsy have on each other. The need to take her medication on a regular basis was emphasized, and the importance of routine prenatal care was stressed. An appointment was scheduled with a maternal-fetal specialist for ongoing prenatal care. At 38 weeks' gestation, S.S. delivered a healthy 2700-g boy with no subsequent problems detected.

Drug Interactions No drugs are known to interfere with the conversion of fosphenytoin to phenytoin. Conversion could be affected by alterations in the level of phosphatase activity, but given the abundance and wide distribution of phosphatases in the body it is unlikely that drugs would affect this activity enough to affect conversion of fosphenytoin to phenytoin. Drugs highly bound to albumin could increase the unbound fraction of fosphenytoin. Although, it is unknown whether this could result in clinically significant effects, caution is advised when administering Cerebyx with other drugs that significantly bind to serum albumin. The pharmacokinetics and protein binding of fosphenytoin, phenytoin, and diazepam were not altered when diazepam and Cerebyx were concurrently administered in single submaximal doses. The most significant drug interactions following administration of Cerebyx are expected to occur with drugs that interact with phenytoin. Pbenytoin is extensively bound to serum plasma proteins and is prone to competitive displacement. Phenygoin is metabolized by hepatic cytochrome P450 enzymes and is particularly susceptible to inhibitory drug interactions because it is subject to saturable metabolism. Inhibition of metabolism may produce significant increases in circulating phenytoin concentrations and enhance the risk of drug toxicity. Phenyto8n is a potent inducer of hepatic drug-metabolizing enzymes. The most commonly occurring drug interactions are listed below: Drugs that may increase plasma phenytoin concentrations include: acute alcohol intake, amiodarone, chloramphenicol, chlordiazepoxide, cimetidine, diazepam, dicumarol, disulfiram, estrogens, ethosuximide, fluoxetine, H2-antagonists, halothane, isoniazid, methylphenidate, phenothiazines, phenylbutazone, salicylates, succinimides, sulfonamides, tolbutamide, trazodone. Drugs that may decrease plasma phenytoin concentrations include: carbamazepine, chronic alcohol abuse, reserpine. Drugs that may either increase or decrease plasma phenytoin concentrations include: phenobarbital, valproic acid, and sodium valproate. Similarly, the effects of phenytoin on phenobarbital, valproic acid and sodium plasma valproate concentrations are unpredictable. Although not a true drug interaction, tricyclic antidepressants may precipitate seizures in susceptible patients and Cerebyx dosage may need to be adjusted. Drugs whose efficacy is impaired by phenytoin include: anticoagulants, corticosteroids, coumarin, digitoxin, doxycycline, estrogens, furosemide, oral contraceptives, rifampin, quinidine, theophylline, vitamin D.

In a first test 325 ng samples of sucrose were injected 3 times ; using a 10 mL loop, i.e. 137 ng of carbon with a concentration of 13.7 ng mL, and resulted in a d13C reproducibility of 0.2% Table 1 ; . The mean d13C value was 10.26% versus a calibrated CO2 reference gas; bulk combustion by EA-IRMS, performed at the same time using the same reference gas tank, gave a d13C value of 10.4%, establishing that the new technique is accurate. The EA results and subsequently the reference gas were calibrated using IAEA-C3 and IAEA-CH6. The m-EA data in Table 1 of sucrose and vanillin show results similar to the EA data.
There is considerable co-morbidity between drug use disorders and other mental disorders. In the recent Australian National Survey of Mental Health and Well-being, two-thirds 65 per cent ; of females with a drug use disorder met criteria for an anxiety, affective or alcohol use disorder. These rates were considerably elevated compared to females without drug use disorders, 12 per cent of whom had another mental disorder.32 Similarly, nearly two-thirds 64 per cent ; of males with a drug use disorder met criteria for another mental disorder. By comparison, in men without a drug use disorder, only 11 per cent had another mental disorder. Overall, four in 10 42 per cent ; individuals with a drug use disorder had a co-morbid physical disorder. A recent analysis by Degenhardt et al.33 has shown that, for cannabis use disorders, the association with anxiety and depression disappears when demographic and other drug use data are considered, indicating that cannabis use on its own does not increase the likelihood of these disorders. However, there remains a significant association between heavier involvement with cannabis and anxiety and depression. There is also good epidemiological evidence that cannabis use exacerbates the symptoms of schizophrenia.34 Previous Australian studies of individuals seeking treatment for opioid and other drug problems have documented high rates of psychiatric co-morbidity among treatment seekers with the most common diagnoses being anti-social personality disorder, affective disorders and anxiety disorders.35 Despite widespread and growing interest in psychiatric co-morbidity, there is relatively little and motilium. Information for Patients: Physicians should instruct their patients to read the Patient Information leaflet before starting therapy with AVODART and to reread it upon prescription renewal for new information regarding the use of AVODART. AVODART Soft Gelatin Capsules should not be handled by a woman who is pregnant or who may become pregnant because of the potential for absorption of dutasteride and the subsequent potential risk to a developing male fetus see CONTRAINDICATIONS and WARNINGS: Exposure of Women--Risk to Male Fetus ; . Physicians should inform patients that ejaculate volume might be decreased in some patients during treatment with AVODART. This decrease does not appear to interfere with normal sexual function. In clinical trials, impotence and decreased libido, considered by the investigator to be drug-related, occurred in a small number of patients treated with AVODART or placebo see ADVERSE REACTIONS: Table 1 ; . Men treated with dutasteride should not donate blood until at least 6 months have passed following their last dose to prevent pregnant women from receiving dutasteride through blood transfusion see PRECAUTIONS: Blood Donation ; . Drug Interactions: Care should be taken when administering dutasteride to patients taking potent, chronic CYP3A4 inhibitors see PRECAUTIONS: Use with Potent CYP3A4 Inhibitors ; . Dutasteride does not inhibit the in vitro metabolism of model substrates for the major human cytochrome P450 isoenzymes CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 ; at a concentration of 1, 000 ng mL, 25 times greater than steady-state serum concentrations in humans. In vitro studies demonstrate that dutasteride does not displace warfarin, diazepam, or phenytoin from plasma protein binding sites, nor do these model compounds displace dutasteride. Digoxin: In a study of 20 healthy volunteers, AVODART did not alter the steady-state pharmacokinetics of digoxin when administered concomitantly at a dose of 0.5 mg day for 3 weeks. Warfarin: In a study of 23 healthy volunteers, 3 weeks of treatment with AVODART 0.5 mg day did not alter the steady-state pharmacokinetics of the S- or R-warfarin isomers or alter the effect of warfarin on prothrombin time when administered with warfarin. Alpha-Adrenergic Blocking Agents: In a single sequence, crossover study in healthy volunteers, the administration of tamsulosin or terazosin in combination with AVODART had no effect on the steady-state pharmacokinetics of either alpha-adrenergic blocker. The percent change in DHT concentrations was similar for AVODART alone compared with the combination treatment. A clinical trial was conducted in which dutasteride and tamsulosin were administered concomitantly for 24 weeks followed by 12 weeks of treatment with either the dutasteride and tamsulosin combination or dutasteride monotherapy. Results from the second phase of the trial revealed no excess of serious adverse events or discontinuations due to adverse events in the combination group compared to the dutasteride monotherapy group.

General Earlier in the report I noted that December 1999 was the 30th anniversary of Elan's formation. We were pleased to host a celebration of that event in Dublin Castle in December. Mr. Brian Cowen TD, then Minister for Health, was the guest of honour and we were particularly pleased to welcome many old friends from the company's past including retired members of senior management and former directors of the company. Our founder, Donald E. Panoz, honoured the gathering with his presence evidencing the continuity and history of Elan from the company that Don started in December 1969. Finally, I would like to take this opportunity to thank you, our shareholders, for your continued support during 1999. The year was not without its difficulties and I appreciated the advice that I received from many of you during the course of that year. We have started 2000 well and I believe that it will be a year of significant advance in moving towards our 2003 goals. I would also like to thank all of the members of the Elan family, my colleagues on the board and, in particular, our employees throughout the world whose combined efforts delivered record revenues and earnings in 1999 and whose productivity in research and development has provided us with a rich and innovative pipeline.

Pharmacy. He said what they intended to pay for was a fair price for the drug, with a reasonable markup and a reasonable fee. My response to him was that the price of a drug, at least in my opinion, has always included the raw material cost, the research that goes into discovering it and bringing it to market, a reasonable profit for the company itself and, like it or not, the cost to advertise and market it. This is the same for both brand name and generic companies.

Combinations involving a device and a drug include a diverse array of products, such as drug-coated devices, drug delivery devices, drugs packaged with devices, and drugs labeled to be used with specific devices. Some combinations--syringes prefilled with a specific drug, for example --offer benefits related to convenience. Others provide significant therapeutic benefits over conventional approaches. For instance, some device implants can deliver a drug directly to the site of its action within the body, as well as control the dosage with need- or time-based release, providing greater efficiency and better therapeutic effect than oral forms of the therapy. As you know, at its November 3, 1999 meeting Senate approved Policy 1406, The Ethics of Research lnvolving Human Subjects, and established the Senate Committee on the Ethics of Research lnvolving Human Subjects SCERIHS ; . This committee is charged with, among other things, monitoring and approving changes to the protocol review process that is undertaken by the various Research Ethics Boards REBs ; that report to SCERIHS. Since the approval of Policy 1406, SCERIHS has been directing its attention to implementing this new policy in order that the University be in compliance with the Tri-Council Policy Statement, Ethical Conduct for Research lnvolving Human Subjects. As part of this process, it has considered various feedback from members of the University's research community. Notable among this feedback was commentary by the University of Manitoba Faculty Association on the new policy and its attendant procedures. Based on the commentary received, SCERIHS approved a number of changes to the procedures attendant to Policy 1406. Enclosed is a copy of the revised procedures. In addition to minor editorial revisions, these revisions include: 1. 2. Clarifying the authority of deansfdirectors and department heads with respect to research that appears not to comply with the policy see section 1.2 Introducing a provision, in certain circumstances, for the review of class-based research projects by facultyfdepartment-based coursework research review committees, as opposed to REBs see section 1.4.2.b. Clarifying the responsibilities of faculty members as supervisors see section 1.5 Assigning the r.eview of human ethics protocols from the Faculty of Pharmacy to the Bannatyne campus REBs see section 2.2.3 Clarifying the procedures for nominating members to REBs see section 2.2.8, for example, phenytoin and phenobarbital.

The high urea content of the gentle foot soak softens hard skin and corns and has a lasting protective effect. Urea also maintains the elasticity of the skin, and is mildly antiseptic and deodorizing. The natural essential oils stimulate the metabolism and encourage blood flow. Oil of thyme has an antiseptic and deodorizing effect, cleansing the feet. Extra relief can be obtained after the foot bath by massaging the feet with a GEHWOL FUSSKRAFT cream suitable for your skin type.

As with nearly all antibacterial agents, diarrhoea, particularly if severe, persistent and or bloody, during or after treatment with Ketek may be caused by pseudomembranous colitis. If pseudomembranous colitis is suspected, the treatment must be stopped immediately and patients should be treated with supportive measures and or specific therapy. Exacerbations of myasthenia gravis haves been reported in patients with myasthenia gravis treated with telithromycin and sometimes. This usually occurred within one to threea few hours after intake of the first dose of telithromycin. Reports have included death and life threatening acute respiratory failure with a rapid onset see section 4.8 ; .in myasthenic patients treated for respiratory tract infections with telithromycin. Telithromycin is not recommended in patients with myasthenia gravis unless other therapeutic alternatives are not available. Patients with myasthenia gravis taking telithromycin should be advised to immediately seek medical attention if they experience exacerbation of their symptoms. Ketek must then be discontinued and supportive care administered as medically indicated see section 4.8 ; . Alterations in hepatic enzymes have been commonly observed in clinical studies with telithromycin. Post-marketing cases of severe hepatitis and liver failure, including fatal cases which have generally been associated with serious underlying diseases or concomitant medications ; , have been reported see section 4.8 ; . These hepatic reactions were observed during or immediately after treatment, and in most cases were reversible after discontinuation of telithromycin. Patients should be advised to stop treatment and contact their doctor if signs and symptoms of hepatic disease develop such as anorexia, jaundice, dark urine, pruritus or tender abdomen. Due to limited experience, Ketek should be used with caution in patients with liver impairment see section 5.2 ; . Ketek may cause visual disturbances particularly in slowing the ability to accommodate and the ability to release accommodation. Visual disturbances included blurred vision, difficulty focusing, and diplopia. Most events were mild to moderate; however, severe cases have been reported. see sections 4.7 and 4.8 ; . There have been post-marketing adverse event reports of transient loss of consciousness including some cases associated with vagal syndrome see sections 4.7 and 4.8 ; . Consideration may be given to taking Ketek at bedtime, to reduce the potential impact of visual disturbances and loss of consciousness. Ketek should not be used during and 2 weeks after treatment with CYP3A4 inducers such as rifampicin, phenytoin, carbamazepine, phenobarbital, St John's wort ; . Concomitant treatment with these medicinal products is likely to result in subtherapeutic levels of telithromycin and therefore encompass a risk of treatment failure see section 4.5 ; . Ketek is an inhibitor of CYP3A4 and should only be used under specific circumstances during treatment with other medicinal products that are metabolised by CYP3A4. In areas with a high incidence of erythromycin A resistance, it is especially important to take into consideration the evolution of the pattern of susceptibility to telithromycin and other antibiotics. In community acquired pneumonia, efficacy has been demonstrated in a limited number of patients with risk factors such as pneumococcal bacteraemia or age higher than 65 years. Experience of treatment of infections caused by penicillin or erythromycin resistant S. pneumoniae is limited, but so far, clinical efficacy and eradication rates have been similar compared with the.

Used in dermatology for the management of stress ulcers and albeit with mixed results- for the treatment of junctional and dystrophic epidermolysis bullosa1. In vitro studies dating as far back as the 1970s suggest that phenytoin inhibits collagenase, an enzyme found at the basement membrane 2 . This offers a plausible explanation for the mechanism of phenytoin in the reduction of blister counts in epidermolysis bullosa, and its efficacy in the maintenance of collagen integrity and wound healing. Phenytoin has also been used to treat a variety of collagen vascular disorders; it has been used with limited success in linear scleroderma in coup de sabre ; and pachyonychia congenita11. In addition, phenytoin has been used to treat lichen planus, rheumatoid arthritis, and neuropathic pain in diabetics12. Along with carbamazepine, phenytoin was the first anticonvulsant to be shown in controlled clinical trials to relieve paroxysmal attacks in patients with trigeminal neuralgia13. In addition to its mechanism in neuromuscular sodium-channel blockade and inhibition of collagenase activity, phenytoin suppresses cortisol, induces the cytochrome P450 enzyme system in the liver, stimulates steroid clearance, and suppresses cytotoxic natural killer T cells10. These effects of phenytoin in immune function and surveillance may partially explain the cutaneous side effects of this drug. The most common cutaneous side effect of phenytoin is gingival hyperplasia, which occurs to some degree in approximately one-half of patients on long-term therapy and interestingly, is not dose-related. Long-term phenytoin therapy can also induce lip enlargement and a coarsening of the facies. Hursutism occurs in over 10% of children receiving phenytoin, usually within 3 months of initiating therapy10. Hair growth occurs on the extensor aspect of the arms and on the trunk and face; this.
Top precautions the liver is the chief site of biotransformation of phenytoin; patients with impaired liver function, elderly patients, or those who are gravely ill may show early signs of toxicity.
