Ps - the good news is that i started on this diet 7 days ago and have continued with my normal exercise regimen jogging 2-3 days a week, lifting light to medium-heavy weights 1-2 ; and i already feel much more energy than i have in 4-5 years. Being treated for hyperlipidemia and has had a stent placed for coronary artery disease. The goal for glucose in this patient should be 80 to 110 mg dL premeal and less than 140 mg dL postmeal, according to the AACE guidelines discussed by Dr. Jellinger. Dr. Bode asked the audience what treatment in addition to diet an exercise should be started in this patient, with no clear consensus. He said that he started the patient on basal bolus therapy. Because the patient refused insulin, Dr. Bode put him on two oral agents and the patient quit drinking sweet tea, colas, and orange juice. A1C at three months was 6.8%. "Advantages of basal insulin are that it's one shot a day; it's slow, safe, and easy, " said Dr. Bode. Case 3 80-year-old white man with diabetes since age 60, on repaglinide 4 mg three times a day. He has a history of congestive heart failure. He has a supportive daughter and wife. Weight is 175 lbs., height is 72 inches, and BMI is 23.5. A1C is 9.2%, creatinine is 2.7, and C-peptide is 5.3 ng ml. Self-monitored blood glucose is tested 2.7 times per day and averages 246 mg dL: 178 in the morning, 206 at noon, 247 in the evening, and 271 at bedtime. "Normally, I would have put a patient like this on basal bolus therapy, but instead I chose premixed insulin, " said Dr. Bode. The patient did well; his weight increased and his A1C was 7.2% at three months. Dr. Bode cited two studies that looked at use of premixed human insulin. In a study by Janka et al. patients with fasting glucose above 120 mg dL were put on either one dose of glargine per day plus continued metformin and sulfonylurea or human premixed 70 30 insulin without the oral agent Diabetes Care. 2005; 28: 254-259 ; . A1C went down from 8.9% to 7.15% with glargine and to 7.5% with premixed insulin. Fewer episodes of hypoglycemia were reported in the glargine group. In the INITIATE study, patients with a fasting glucose above 140 mg dL were put on glargine 10 units once a day titrated to 80 to 110 units ; plus metformin and, in some cases, a thiazolidinedione or biphasic insulin aspart, 5 or 6 units twice a day, plus metformin Diabetes Care. 2005; 28: 260265 ; . In this study, premixed insulin reduced A1C greater than glargine 6.9% versus 7.4% ; . Case 4 49-year-old white woman with diabetes since age 37, on glargine insulin at bedtime for three years. Weight is 223 lbs., height is 65 inches, and BMI is 37. A1C is 11.6%, creatinine is 1.2, and C-peptide is 2.9 ng ml. Current treatment is repaglinide 4 mg and glargine 47 units at bedtime. She cannot tolerate metformin or TZD. Her diet includes a lot of high-fat, high carbohydrate food with sweets and her activity is minimal. Selfmonitored blood glucose taken once a day averages over 300 mg dL. In addition to diabetes training and management by a certified diabetes educator, Dr. Bode added bolus insulin to each meal. She was put on aspart 10 units in the morning, 7 units at noon, and 7 units in the evening ; and glargine 40 units at bedtime. After intensive management training in MDI and diet, the patient's self-monitored blood glucose taken 6.5 times a day was 121 mg dL and A1C was 6.5 and nateglinide.

Increase by similar amounts ; in patients taking rosiglitazone and pioglitazone. Pioglitazone and rosiglitazone cause a small but significant increase in high-density lipoprotein, often called "good cholesterol" because it promotes the breakdown and removal of cholesterol from the body. Glimepiride, glipizide, glyburide, and repaglinide are associated with hypoglycemia when blood glucose levels go too low ; more than other diabetes drugs. Metformin and acarbose are generally more likely than other diabetes medications to cause gastrointestinal problems such as diarrhea. Patients who used metformin alone were more likely to experience problems than those using the drug at a lower dose in combination with glimepiride, glipizide, glyburide, pioglitazone, or rosiglitazone. Patients who take pioglitazone and rosiglitazone have a greater risk of congestive heart failure compared with those who take metformin, glimepiride, glipizide, or glyburide. While one recent analysis raised the possibility that rosiglitazone may also increase heart attack risks, authors of the AHRQ analysis concluded that current evidence is not sufficient to make a meaningful assessment. Additional studies are needed to understand the impact of oral diabetes drugs on patients' quality of life and whether long-term use causes adverse side effects or reduces important complications of diabetes such as heart disease and kidney disease. More research is needed to study interactions between the drugs and to compare therapeutic combinations of the drugs, according to the report. The report, Comparative Effectiveness and Safety of Oral Diabetes Medications for Adults with Type 2 Diabetes, is the newest analysis from AHRQ's Effective Health Care program, authorized by the Medicare Prescription Drug, Improvement and Modernization Act. That program represents an important Federal effort to compare alternative treatments for health conditions and make the findings public. The program is intended to help patients, doctors, nurses, and others choose the most effective treatments. Information can be found at : effectivehealthcare.ahrq.gov. I and glimepiride. However, at the time of ovulation cervical mucus should change to encourage sperm survival. Repaglinide mode of action Lation may be increased. No adjustment in dosing is needed in renal impairment until the patient has endstage renal disease. When low-dose sulfonylureas cause hypoglycemia in renally impaired type 2 diabetic patients, repaglinide or nateglinide may be a good therapeutic alternative. Neither has significant drug-food interactions, but both should be taken preprandially to better match pancreatic insulin release with a meal Table 1 ; . Metformin. Although not because of a drug interaction, metformin should be taken with a meal to limit gastrointestinal side effects. Metformin may cause malabsorption of vitamin B12, which may result in B12 deficiency and subsequent anemia. The mechanism by which metformin causes malabsorption of B12 is not clearly defined, although oral or injected B12 cyanocobalamin ; or calcium supplementation may be effective for correction24, 25 Table 1 ; . Metformin does not undergo metabolism and is eliminated renally by tubular secretion and glomerular filtration. Metformin is a cationic positively charged ; molecule and may compete with other cationic drugs for renal secretion through organic cation transporters in the kidneys.17 Procainamide, digoxin, quinidine, trimethoprim, and vancomycin are all cationic drugs that have the potential to interact with metformin, but only cimetidine, which is available over the counter for heartburn, has been implicated in one case of metformin-associated lactic acidosis MALA ; 26, 27 Table 1 ; . Metformin has many drug-disease interactions that can increase the risk of MALA. Metformin may increase lactic acid production from the splanchnic tissues slightly, but MALA occurs in the setting of comorbid diseases that increase systemic levels of lactic acid or reduce elimination of metformin. Any disease that may increase lactic acid production or decrease lactic acid metabolism may predispose to lactic acidosis. Tissue hypoperfusion from congestive heart failure, hypoxic states, shock, or septicemia can increase lactic acid production, and alcohol or severe liver disease can reduce removal of lactic acid in the liver, increasing the risk of lactic acidosis and terbinafine. Syndrome, peripheral neuropathies, gastrointestinal GI ; problems, line sepsis or peritonitis, other infections, foot problems clotting abnormalities, fluid overload, significant cardiovascular disease, high potassium, circulation problems and pain. Antihyperglycemic agents 2-5 ; Insulin metabolism is altered in ESRD. It is ~40% metabolized by the kidney and 50% by the liver. In those with renal failure, uremia affects the liver's ability to metabolize insulin and the kidneys are not effective at metabolizing insulin therefore the half-life of insulin is prolonged. The degree of uremia fluctuates between dialysis sessions, complicating the picture even further. Insulin is not dialyzed by either hemodialysis or peritoneal dialysis treatments further prolonging its action. Oral antihyperglycemic agents must be carefully selected for dialysis patients. Metformin is contraindicated. Glyburide accumulates in renal failure normally excreted 50% in urine and 50% in feces as active metabolites ; and can cause severe hypoglycemia, although some patients tolerate small doses. Gliclazide Diamicron ; , glimepiride Amaryl ; , repaglinide GlucoNorm ; rosiglitazone Avandia ; and pioglitazone Actos ; are suitable for use in the dialysis patients however, starting doses should be low. Nateglinide Starlix ; could be used cautiously starting with a low dose as its metabolites are mildly active and ~14% is not metabolized. Acarbose Glucobay ; is not significantly absorbed and 2% is excreted in the urine, however long-term use has not been investigated in this population therefore it is not recommended. Many other issues must be considered when planning diabetes treatments for patients on dialysis. Dietary concerns Patients are fluid restricted usually 1000 to 2000 ml per day ; . Hyperglycemia leads to extreme thirst and dangerously large fluid gains between dialysis treatments. Patients have phosphate and potassium Continued on page 7! It is appropriate for GPs to prescribe repaglinide for the treatment of type 2 diabetes where indicated. Because it acts rapidly, repaglinide may be particularly useful for patients with an irregular life-style and during periods of fasting such as Ramadan and clotrimazole. Autophosphorylation of PpCaMK in a concentration dependent manner and 50% inhibition was attained at a concentration of 4 M. Thus, repaglinide was more effective in the inhibition of Ca2 + -dependent autophosphorylation of PpCaMK as compared to that of lily CCaMK. Both trifluoperazine and glibenclamide had no effect on the PpCaMK autophosphorylation Fig. 7E ; . The differential inhibition of CCaMK and 21. Repaglinide alternative 2. Effects of inhibitors of CYP enzymes on glimepiride and repaglinide 2.1. Fluconazole effects on glimepiride Study IV and betamethasone. I'm happy to say, that 7 months post-transplant, almost all of the drugs have been stopped. The nonsulfonylurea secretagogues repaglinide and nateglinide provoke rapid secretion of endogenous insulin with meals 17 , 18 and ketoconazole. Discount Repaglniide online Longer on the second ETT as compared to the first. In contrast, pre-treatment with glyburide abolished these exerciseinduced changes, suggesting that glyburide treatment abolishes these clinical markers of ischemic preconditioning. In the second study, 23 ischemic preconditioning was modeled in the cardiac catheterization laboratory by repeated inflations of an angioplasty balloon. In patients receiving a placebo infusion, the magnitude of ST segment depression decreased progressively with subsequent balloon inflations, indicating that the balloon inflations induced ischemic preconditioning. Following a glimepiride infusion, patients had similar, progressive decreases in ST segment depression with subsequent balloon inflations, suggesting no adverse effect of glimepiride on ischemic preconditioning. In contrast, patients pre-treated with glyburide had no change in the magnitude of ST segment depression with subsequent balloon inflations, suggesting that glyburide, but not glimepiride, impaired ischemic preconditioning. Thus, while older sulfonylureas do have the potential to impair ischemic preconditioning, this does not appear to be a concern with newer-generation sulfonylureas, such as glimepiride. Meglitinide analogs The meglitinide analogs, including nateglinide Starlix ; and repaglinide Prandin ; , are nonsulfonylurea secretagogues that also bind to KATP channels, albeit at a different site than traditional sulfonylureas. In general, meglitinide analogs have much shorter half-lives than do sulfonylureas. The meglitinide analogs affect both sarcolemmal and mitochondrial KATP channels, and the different agents may vary in their relative selectivities for KATP channels at these different intracellular sites.24 Whether the meglitinide analogs have adverse effects on ischemic preconditioning is not known. However, both nateglinide and repaglinide have plasma half-lives of 2 h, and plasma insulin decreases to basal levels within 2 h after.

Associated with serious long-term microvascular disease e.g. nephropathy, retinopathy, and 3 neuropathy ; and macrovascular complications e.g. coronary heart disease, stroke, and peripheral vascular disease ; . Patients with type 2 diabetes are two to five times more likely to suffer cardiovascular morbidity.3 Dietary and lifestyle modifications form the mainstays of therapy for type 2 diabetes, but 50 to 70% of patients will also require an oral antidiabetic drug, and many will eventually need treatment with insulin. Drug treatments currently available include metformin, sulphonylureas, thiazolidinediones rosiglitazone and pioglitazone ; , acarbose, repaglinide and nateglinide, exenatide, sitagliptin, vildagliptin and insulin. Metformin followed by the sulphonylureas are considered to be the first choices for oral antidiabetic 4 therapy. Pioglitazone lowers blood glucose by reducing peripheral insulin resistance.1 The National Institute for Health & Clinical Excellence NICE ; recommends the use of a glitazone in combination with either metformin or a sulphonylurea as an alternative to a combination of metformin with a sulphonylurea ; only for patients who cannot tolerate either drug in the combination. Current NICE guidance does not apply to the use of glitazones as mono- or triple oral therapy and butenafine. P33a Polymorphism in the MTHFR gene affects thiopurine methyltransferase activity A.M. Marinaki1, M. Arenas1, J.A. Duley2, E.A. Shobowale-Bakre1, A. Ansari1, J.D. Sanderson1, L.D. Fairbanks1 1 Guy's Hospital, LONDON, United Kingdom 2 University of Queensland, QUEENSLAND, Australia In this study, we investigate the effect of common genetic polymorphism in the MTHFR methylenetetrahydrofolate reductase ; gene on erythrocyte activity of TPMT thiopurine methyltransferase ; . SAdenosyl-methionine SAM ; is the methyl donor for the reaction catalysed by TPMT, and is converted to Sadenosyl-homocysteine SAH ; . The adenosyl moiety of SAH is subsequently cleaved and homocysteine remethylated to methionine. A common polymorphism in the MTHFR gene, the thermolabile 677C T variant, is associated with decreased MTHFR enzyme activity and impaired remethylation of homocysteine to methionine leading to mild homocysteinaemia. We proposed that the MTHFR 677C T variant may indirectly affect TPMT activity. The frequency of the MTFHR 677TT homozygous genotype was compared between 52 patients with intermediate TPMT activity 4-8U ; and a wild type TPMT genotype, and 55 patients with normal TPMT activity and genotype in the range 12-15U ; . The MTHFR 677TT genotype was significantly under-represented in the normal activity group p 0.0296 ; . In order to establish whether MTHFR genotype was associated with adverse drug reactions to AZA, MTHFR 677TT genotype frequencies in a cohort of 61 IBD patients who had experienced adverse drug reactions to AZA therapy were compared to 68 patients who had no side effects. The MTHFR 677TT genotype was not significantly associated with adverse drug reactions to AZA. Although the MTHFR 677C T allele and 677TT genotype appeared to be under-represented in a subset of 16 patients with hepatitic, pancreatic or abdominal pain side effects, the association was not quite significant. The accumulation of methylated thio-nucleotides in patients has been suggested as a cause of pancreatic and hepatic side effects. Our results suggest that MTFHR genotype indirectly influences TPMT activity, and imply that a wild type MTHFR genotype may be necessary for a high methylator phenotype. More patients with pancreatic or hepatitic side effects should be genotyped for MTHFR to establish the role of folate metabolism in methylated thionucleotide toxicity.

Repaglinide vs. glyburide: significant regression of atherosclerosis despite no significant change in other risk factors: eg, BMI, blood pressure, total cholesterol, triglycerides! What happens to a person through out their life as a result of experience and culture carves a groove in the nervous system in a way and that will effect the entire body systemically. Keeping the groin area dry, clean and avoiding chafing can aid in preventing tinea cruris. In the above table, the risk of death from any birth control method is less than the risk of childbirth, except for oral contraceptive users over the age of 35 who smoke and Pill users over the age of 40 even if they do not smoke. It can be seen in the table that for women aged 15 to 39, the risk of death was highest with pregnancy 7-26 deaths per 100, 000 women, depending on age ; . Among Pill users who do not smoke, the risk of death was always lower than that associated with pregnancy for any age group, except for those women over the age of 40, when the risk increases to 32 deaths per 100, 000 women, compared to 28 associated with pregnancy at that age. However, for Pill users who smoke and are over the age of 35, the estimated number of deaths exceeds those for other methods of birth control. If a woman is over the age of 40 and smokes, her estimated risk of death is four times higher 117 100, 000 women ; than the estimated risk associated with pregnancy 28 100, 000 women ; in that age group. The suggestion that women over 40 who do not smoke should not take oral contraceptives is based on information from older high-dose pills and on less-selective use of pills than is practiced today. An Advisory Committee of the FDA discussed this issue in 1989 and recommended that the benefits of oral contraceptive use by healthy, non-smoking women over 40 years of age may outweigh the possible risks. However, all women, especially older women, are cautioned to use the lowest-dose pill that is effective. WARNING SIGNALS If any of these adverse effects occur while you are taking oral contraceptives, call your doctor immediately: Sharp chest pain, coughing of blood, or sudden shortness of breath indicating a possible clot in the lung ; Pain in the calf indicating a possible clot in the leg ; Crushing chest pain or heaviness in the chest indicating a possible heart attack ; Sudden severe headache or vomiting, dizziness or fainting, disturbances of vision or speech, weakness, or numbness in an arm or leg indicating a possible stroke ; Sudden partial or complete loss of vision indicating a possible clot in the eye ; Breast lumps indicating possible breast cancer or fibrocystic disease of the breast; ask your doctor or healthcare provider to show you how to examine your breasts ; Severe pain or tenderness in the stomach area indicating a possibly ruptured liver tumor ; Difficulty in sleeping, weakness, lack of energy, fatigue, or change in mood possibly indicating severe depression ; Jaundice or a light yellowing of the skin or eyeballs, accompanied frequently by fever, fatigue, loss of appetite, dark-colored urine, or light-colored bowel movements indicating possible liver problems ; SIDE EFFECTS OF ORAL CONTRACEPTIVES 1. VAGINAL BLEEDING Irregular vaginal bleeding or spotting may occur while you are taking the pills. Irregular bleeding may vary from slight staining between menstrual periods to breakthrough bleeding, which is a flow much like a regular period. Irregular bleeding occurs most often during the first few months of oral contraceptive use, but may also occur after you have been taking the Pill for some time. Such bleeding may be temporary and usually does not indicate any serious problems. It is important to continue taking your pills on schedule. If the bleeding occurs in more than one cycle or lasts for more than a few days, talk to your doctor or healthcare provider. All these, inevitably, resulted in poor control of hyperglycemia; multiple, multi organ complications, severe morbidity and mortality and very poor quality of life despite increased and often fruitless expenditure. In another 10 years revolutionary changes will take place in the management of diabetes and we would even target for a cure. But before that, there is much that we could do just now. Let us have a critical look at our current armoury and how best we could use it. Lifestyle modification is the talk of the day. To make it acceptable we have turned around 180 degrees. No longer is a rigid diet and exercise protocol imposed upon the patient. A relaxed diet with exchanges, to offer variety and liberty to the patient, have made them much more compliant. Exercises are prescribed after a screen for CVD and retinopathy, and there too, a varied and attractive menu is offered including yoga and pranayam. A mini revolution has occurred in the segment of the oral agents. Now we have rather a large basket to choose from. On one hand, we have the secretagogues, which again are divided into the sulfonylureas and non-sulfonylureas. No longer is a rigid diet And exercise protocol Imposed upon the patient. A Relaxed Diet with exchanges offer Variety and liberty To the patient. Exercises are Prescribed after a screen For CVD and Retinopathy, and there too, a Varied and attractive Menu is offered including Yoga and pranayam Among the sulfonylureas we have the two new molecules glimepiride and glicazide. Both have favourable cardiac profile, fewer side effects, less potential for weight gain and less hypoglycemia. There are claims that glimeperide also has some peripheral sensitizing activity. We also have the newer rapid acting secretagogues Repagllnide and Nateglinide, ideally suited as mealtime secretagogues with better control of post parandial sugar levels. Repaglinide, with hepatic metabolism, is the only drug approved for use in renal impairment. Among the sensitisers, the age-old metformin has been made more user-friendly with the advent of extended release formulations, which are also less gastric irritant. The newer sensitisers pioglitazone and rosiglitazone are there to stay. They are peripheral insulin sensitizers and compliment the hepatic sensitization property of metformin. They, especially pioglitazone, have a very favourable action on the lipid profile. The major side effects, however are a potential for modest weight gain of around 3 to 5 and also fluid retention, which make them an absolute no-no in patients having frank or latent heart failure. Also, in view of the potential for liver toxicity, a close monitoring of the liver enzyme ALT should be done periodically. Acarbose and Miglitol and of late voglibose ; are intestinal alpha glucosidase enzyme inhibitors and are excellent molecules in patients who refuse to cut down the carbohydrate load in their diet. They also have favourable effects on the lipid profile and weight. Another significant concept is that of early introduction of combination therapies. In doing this, better glycemic control is attained as different drugs with different mechanisms of action are used together. The motto is clear; go all out to achieve the target, i.e. normoglycemia. But, despite these, there comes a time, even in the type 2 diabetic, when the oral drugs fail and it is time to go for Insulin. To quote "it is great art, probably the greatest, to know when to say goodbye". Dramatic advances have taken place in availability and use of insulin. Over the years, the source of insulin has changes from bovine to porcine to human R-DNA using Ecoli ; and now to analogues where the whole parent molecule has been tampered with to give it user-friendly profiles. Over the ages the traditional short and long acting insulins have evolved and now we have the ultra short rapid ; acting analogues like lispro and aspart which and buy nateglinide. Repaglinide is more efficient in increasing insulin action and insulin secretion mediated by glucose or induced by a mixed meal than is glimepiride. Fourteen patients between 50 and 80 years of age, all with type 2 diabetes, participated in the randomized, cross-over parallel group trial comparing the effects of repaglinide and glimepiride. The 9 men and 5 women were all nave for diet treatment. The patients were started on a hypocaloric diet during the 2-week run-in period after enrolment, following which they were randomly assigned for 4 weeks to repaglinide 1 mg twice a day before lunch and dinner, or to glimepiride 2 mg once a day before lunch, while maintaining their diet. Patients were then prescribed a standard meal test with a caloric value of 500 Kcal 55% carbohydrate, 30% fat, 15% protein ; and a hyperglycemic clamp intravenous bolus of 20% glucose over 1-2 minutes ; , after an overnight fast and with an interval of at least 24 hours between the tests. A wash-out period followed for 2 weeks before starting the cross-over treatment for another 4 weeks. Meal tests and hyperglycemic clamps were then repeated in reverse order. Sampling for glucose, insulin and C-peptide was performed throughout the glucose infusion. Patients received their medication orally 15 minutes before the meal test. Plasma glucose, insulin, total cholesterol, triglycerides and free fatty acids were obtained from venous blood samples at predetermined intervals after the meal. At baseline, both treatments were responsible for important declines in fasting plasma glucose, total cholesterol and triglycerides levels. During the hyperglycemic clamp, incremental plasma insulin and C-peptide concentrations reached significantly higher values after repaglinide than with glimepiride administration at different study times. Steady state plasma insulin and C-peptide levels were also higher after repaglinide administration as were the incremental first and second phase of insulin secretion. Repaglinid3 resulted in a greater improvement in insulin action and amelioration of hepatic clearance than glimepiride. During the meal test, repaglinide was associated with a more rapid onset of insulin secretion, which reached a peak at 45 min in the repaglinide-treated patients compared to 60 min in the glimepiridetreated patients. Only 3 patients treated with repaglinide experienced a mild episode of symptomatic hypoglycaemia while 2 patients treated by glimepiride reported such an event. "Our study demonstrates that multiple daily doses of repaglinide are more efficient than glimepiride on improving glucose- and mixed meal-induced insulin secretion as well as on insulin action, " conclude the authors. Diabetes Metab 2004 Feb; 30: 1: 81-9. P. Offit. The Children's Hospital of Philadelphia, Division of Infectious Diseases, Philadelphia, PA, USA Rotaviruses are an important cause of morbidity in the developed world and of mortality in the developing world. Protection against disease following natural infection is mediated primarily by virus-specific sIgA present at the intestinal mucosal surface . However, production of virus-specific IgA by B cells located in the small intestinal lamina propria is short-lived.As a consequence, protection against rotavirus disease following natural rotavirus. Of repaglinide, with a nonsignificant 0.35 kg weight increase in this group. An analysis of weight change by preferred daily meal frequency revealed no clear trends because the magnitude of mean weight change between baseline and end point was small, but with wide standard deviations in all patient categories Table 2 ; . Safety and adverse events As expected, the most frequent adverse event during the study was hypoglycemia. Some 17% of patients in the repaglinide group 18% during treatment with 0.5 mg meal, 11% during treatment with 1.0 mg meal ; and 3% in the placebo group reported minor episodes during the study. Three repaglinide-treated patients 1% ; reported a total of four major hypoglycemic events. The baseline HbA1c values for these patients were 7.2, 7.8, and 8.5%. One major event occurred in a patient receiving 0.5 mg meal repaglinide 16-week patient incidence 0.5% ; , and the remainder occurred in patients receiving 1 mg meal 16-week patient incidence 2.4% no hypoglycemic events required hospitalization or intravenous glucose or glucagon. There was no indication that the risk of hypoglycemia in the repaglinide group was related to meal pattern: 15% of patients taking two or fewer meals daily had a hypoglycemic episode compared with 19% of patients taking three meals and 7% of patients taking four or more meals daily!

The aims of this work were to investigate the effects of induction of drugmetabolizing enzymes, with rifampicin as the model inducer, on the pharmacokinetics and pharmacodynamics of the oral antidiabetic drugs, glibenclamide, glimepiride, glipizide, and repaglinide, and to investigate the effects of inhibition of CYP2C9 on the pharmacokinetics and pharmacodynamics of glimepiride, with fluconazole, fluvoxamine, and gemfibrozil as model inhibitors of CYP2C9. In addition, the effects of inhibition of CYP3A4 on the pharmacokinetics and pharmacodynamics of repaglinide were investigated, with clarithromycin as the model inhibitor. A total of 9 to healthy volunteers participated in each study, except in Study II, in which 20 volunteers participated, because it comprised two separate substudies. All the studies were randomized, placebo-controlled crossover studies with 2 to 3 phases in each. Pretreatment with the inducer or inhibitor was followed by a single dose of antidiabetic drug, whereafter blood samples were collected for the determination of plasma drug, blood glucose, and, in two of the six studies, serum insulin concentrations. Rifampicin reduced the plasma concentrations of all of these oral antidiabetic drugs and also significantly reduced the blood glucose-lowering effects of glibenclamide and repaglinide. Rifampicin reduced the AUC of glipizide, glimepiride, glibenclamide, and repaglinide by 22% P .05 ; , 34% P .001 ; , 39% P .001 ; , and 57% P .001 ; , respectively. Fluconazole considerably elevated the plasma concentrations of glimepiride, whereas fluvoxamine and gemfibrozil caused only moderate increases in the plasma glimepiride concentrations. Fluconazole, fluvoxamine, and gemfibrozil elevated the AUC of glimepiride by 138% P .0001 ; , 33% n.s. ; , and 23% P .005 ; , respectively. None of these drugs significantly affected the blood glucose-lowering effect of glimepiride in healthy volunteers. The low 250-mg twice-daily dose of clarithromycin raised the AUC and Cmax of repaglinide by 40% P .0001 ; and 67% P .005 ; , respectively. Clarithromycin raised the incremental AUC 0-3 ; of serum insulin and the maximum increase in the insulin concentration after repaglinide by 51% P .05 ; and 61% P .01 ; , respectively. Dose adjustment in patients with renal insufficiency is not recommended see clinical pharmacology, pharmacokinetics and drug metabolism.
