| OBJECTIVE -- To examine the effect of glimepiride on insulin-stimulated glycogen synthesis in cultured human skeletal muscle cells in comparison with glibenclamide. RESEARCH DESIGN AND METHODS -- Myotubes derived from glucose-tolerant subjects were incubated with glimepiride or glibenclamide 0 100 mol l ; for 4 h and with or without insulin 100 nmol l ; for 2 h, and subsequently glycogen synthesis was determined. RESULTS -- Glimepiride had no significant effect on basal glycogen synthesis; in contrast, glimepiride caused a dose-dependent increase of insulin-stimulated glycogen synthesis, with a maximal effect of 39.97 8.4% mean SEM, n 4, P 0, 02 ; . The time course of this glimepiride effect on insulin-stimulated glycogen synthesis showed a peak after 12 h incubation with a half maximal effect after 4 h. Preincubation of the myotubes with wortmannin 100 nmol l ; , an inhibitor of phosphatidylinositol PI ; - 3 kinase, caused an inhibition of this glimepiride effect on insulin-stimulated glycogen synthesis. In contrast to glimepiride, incubation of myotubes with glibenclamide 0 100nmol l ; , a second generation sulfonylurea, had no significant effect on basal or insulin-stimulated glycogen synthesis. CONCLUSIONS -- Incubation of cultured human skeletal muscle cells derived from glucose-tolerant subjects with glimepiride caused a dose-dependent increase of insulin-stimulated glycogen synthesis using therapeutic glimepiride concentrations. This glimepiride effect seems to be mediated via the PI3 kinase pathway. In contrast to glimepiride, glibenclamide had no significant effect on basal or insulin-stimulated glycogen synthesis. These results suggest that glimepiride, beside its well-known effect to stimulate insulin secretion, possess an insulinsensitizing action in cultured human skeletal muscle cells in support of the concept of an extrapancreatic action of glimepiride.

Sulfonylureas were the first oral agents developed and have remained the mainstay of therapy since the early 1950s. They act primarily by stimulating pancreatic insulin production and may have limited effects on insulin sensitivity at the end organs, muscle and fat. Sulfonylureas bind to sulfonylurea receptors on the beta-cell membrane that are in close relationship with ATP-dependent potassium channels. The potassium channels then close, resulting in a cascade of reactions culminating in the exocytosis of insulin-containing secretory granules. In monotherapy these agents reduce HbA1c levels by 0.8-2.0% and fasting plasma glucose levels by 3.3-3.9mmol L. As these agents are generally associated with weight gain, they are usually reserved as second-line therapy for overweight patients. Hypoglycaemia is the most significant side effect and occurs more commonly with sulfonylureas with long half-lives and those metabolised to active metabolites with significant renal excretion. Glipizide and gliclazide are associated with lower incidences of hypoglycaemia. Glimepiride Amaryl ; , the most recently marketed sulfonylurea in Australia, is a long-acting sulfonylurea that can be given once daily. The starting dose is 1mg day, which can then be increased by 1mg every 1-2 weeks until the desired glycaemic target is obtained. Most patients are controlled on 4mg or less but some require up to 8mg day. Glimepiride should be taken before breakfast and reaches maximum serum concentration within three hours and has a half-life of 5-8 hours. Its major metabolite also has hypoglycaemic action, which allows a single dose to have a duration of action of 24 hours. It is completely metabolised, with most metabolites being excreted in the urine. Glimepiride should therefore be avoided in patients with severe renal and hepatic impairment. Like all sulfonylureas glimepiride can cause hypoglycaemia although post-marketing studies have suggested its hypoglycaemic potential is initially less than that of glibenclamide.
Annex V shows the affordability of standard treatments across sectors. Disease rarely affects only one person in a family. Consider a family situation - father with an ulcer needing ranitidine 150mg twice daily, mother on glibenclamide 5mg twice daily for diabetes and child with asthma needing a salbutamol inhaler. Can they afford medicines if purchased in private pharmacies? Table 12 shows that clearly such treatment is unaffordable even when the cheapest generics are purchased. Table 12.

Elderly aged over 65 years ; Tennessee from 1985 to 1989 were highest for glibenclamide 16.6 ; , second highest for chlorpropamide l5.3 ; , and lowest It is noteworthy that although for tolbutamide 3.5 ; . the duration of action of glibenclamide 16-24 hours ; is much shorter than chlorpropamide 60 hours ; , glibenclamide has a higher risk of hypoglycaemia in elderly diabetics. The protracted hypoglycaemic effects of glibenclamide has been attributed to the prolonged presence of active metabolites; and the delayed beta-cell response elicited by this drug in the absence of an early first phase peak of insulin release 33. Both these factors are absent for tolbutamide and gliclazide, sulphonylureas that are thought to be safer and thus recommended in elderly diabetics 34-36.Pharmacological, epidemiological and clinical data of an increased frequency of hypoglycaemia associated with glibenclamide led to guidelines recommending their avoidance in eldAn audit in UK on the geriatricians' erly diabetics37. and diabetologists' management of elderly diabetics from 1988 to 1992 showed a decreasing trend of glibenclamide use and an increasing preference for shorter-acting hypoglycaemic agents 38. However, glibenclamide is widely prescribed to our elderly diabetics locally. To reduce drug-related iatrogenic disease, doctors should heed of the recommendations from a recent report of the Royal College of Physicians 39: think carefully before prescribing: prescribe with maximum knowledge about the patient and about therapeutics; monitor the patient for the efficacy and side-effects of medication: help the patient make better use of their medication: and agree responsibility for prescribing across the primary secondary interface. Using computers to store prescribing information can be helpful, though the role of the intracranial computer still remain paramount 16.40. The focus on iatrogenic illness in old age caused by prescribed medication should not divert attention from other non-drug related iatrogenic conditions: ageism, inadequate assessment, sick-role regimentation for staff convenience, disinduction, and diagnostic abling environment equipment procedure-related complications8.41. therapeutic Much knowledge has been accumulated for the better care of our elderly people. as can be seen from the articles devoted to ageing in the October 1997 issues of 100 journals from 33 countries to commemorate the "Ageing: a global theme" 42.43. Hopefully, with improved attitude, knowledge and skills among doctors caring for old people, the geriatric giant "iatrogenesis" will be tamed. Dr. Tak-Kwan.
Conclusions KATP channel constituents are diet-responsive, thereby high intake of metabolizable energy can alter channel composition. This change may have physiological consequences indicated by glibenclamide binding in vitro and by the responses of the heart rate and venous flow to the KATP opener, levcromakalim, since they were reduced or abolished by glibenclamide. As heart rate and metabolic rate are correlated, the results strongly suggest involvement of KATP channels in the metabolic regulation of whole animals and changes in KATP channel composition contribute to changes in their function and itraconazole.

Patients in our study was glibenclamide glyburide ; , and its use was not associated with a higher risk of not surviving an acute myocardial infarction when compared to a group of Type 2 diabetic patients on other treatments Fig. 1, Table 6 ; . Not surprisingly, all previously known Type 2 diabetic patients, no matter whether treated with diet alone, sulfonylurea drugs, other oral agents or insulin were characterized by an in-hospital mortality rate substantially and certainly significantly ; different from that in non-diabetic patients, the relative risk of dying being well within the previously reported range[2022, 23].

Time because of multiple potential problems that are increased in older people including gastric toxicity, nephrotoxicity and several drugdrug and drugdisease interactions. Opioids are probably under-utilised in many older people and may have fewer long-term problems for some older people compared to NSAIDs. Newer anticonvulsant drugs such as NSAIDs and others may be the first drugs to try for neuropathic pain because of their low side-effects. Traditional tricyclic anti-depressants are not first-line choices today because of their higher incidence of anticholinergic effects. It is important to remember that most non-traditional analgesic drugs for neuropathic pain are only partially effective and they are rarely effective as a single line therapy. There are a few drugs that should be avoided in older people. There is no justification for the use of placebos. Meperidine has an active metabolite that can cause seizures. Mixed opioid agonists-antagonists often have narrow therapeutic windows and may be associated with more delirium. Caution should be taken with those drugs that have extreme half-lives. New medications and new evidence are appearing often and it is important to keep abreast of the latest new findings. References, for example, glibenclamide hplc.

Electrophysiology and ion flux measurements Results of patch-clamp studies of single rat pancreatic beta-cells showed that the effect of nateglinide is rapid and reversed upon removal of the compound. Nateglinide was less potent than repaglinide, glimepiride or glibenclamide whereas the potency of nateglinide was increased 3-fold ; with increasing glucose levels. The effects of nateglinide compared to repaglinide, glimepiride and glibenclamide on the membrane potential of rat pancreatic beta-cells were also studied in the presence of metabolic inhibitors. The IC50 value for closure of K + channels of nateglinide was over 400-fold lower in the presence of metabolic inhibitors; Ion flux experiments showed that stimulation of the L-type Ca + channel and inhibition of the delayed rectifier Kv K + channels were only observed at high doses with reduced magnitude of effects, thus direct effects are not thought to contribute to the overall response of nateglinide. Insulin secretion kinetics of insulin secretion The effects of nateglinide on insulin release were confirmed from studies on isolated Langerhans islets and beta-cells lines and compared with other insulinotropic agents repaglinide, glibenclamide and tolbutamide ; . Similar glucose sensitizing effects were also demonstrated in studies using rat pancreatic beta-cells; nateglinide left-shifted the glucose dose-response curve for insulin release and acted as a sensitizer of glucose-stimulated insulin secretion. No effect of nateglinide on glucagon secretion was observed at therapeutically relevant concentrations. Kinetics of insulin release in-vitro and in-vivo studies ; The kinetics of nateglinide on hormone secretion were studied using pancreas preparations, islets and in in vivo studies Cynomolgus monkey ; . Nateglinide stimulated insulin release with a preferential effect on the early phase of insulin release while repaglinide and glipizide have a slower and longer insulinotropic effect. In rat models of type 2 diabetes or in rats fed with a high fat diet pre-meal dosing ; , gliclazide and nateglinide had similar initial efficacy followed by increase over time with nateglinide whereas it decreased with gliclazide. The pancreatic content of insulin was higher at the end of the study with nateglinide; nateglinide stimulated insulin release only during meals.
In experiments conducted in vivo in control and diabetic rats, repaglinide provokes a greater and more rapid increase in plasma insulin concentration and an earlier fall in glycemia than glibenclamide or glimepiride and lansoprazole.

The measurement of fluo-3 fluorescence. Fixed cells were stained using rabbit polyclonal anti-GFAP and mouse monoclonal anti-synaptophysin. Primary antibodies were then treated with goat anti-mouse IgG FITC ; and goat anti-rabbit IgG TRITC ; . Neurones were identified by their positive staining for synaptophysin and by the absence of staining for GFAP. Consistent with previous reports using neurobasal media 16 ; , very few of the cells 5% ; were glia in our culture. Coverslips containing cultured hippocampal neurones were placed in a microscope chamber for Ca2 measurements as described above. Test compounds and drugs were added to the chamber either through a gravity-fed perfusion system or via direct addition into the chamber and loratadine!
On the basis of the questions raised by Austria and Portugal, the points to be considered by the CPMP are: 1. Amaryl causes uterine adenocarcinomas in rats with an AUC which is less than 10-fold as compared to the AUCs in human therapeutic use. Until now, carcinogenicity has never been a problem in the long term clinical use of sulphonylurea derivatives, nor in the available toxicological studies. The relevance of this finding for man should be discussed in depth. 2. Glycemic control with Amaryl, as measured by HBA1c and fasting blood glucose levels, seems to be inferior as compared to glibenclamide studies B19 and B21 ; . 3. In view of the possible carcinogenic potential and the less effective glycemic control the benefit risk ratio for Amaryl is considered to be negative. Written explanation was provided by the company on 29 February 1996.

In animal cells, ATP binding cassette ABC ; proteins are a large family of transporters that includes the sulfonylurea receptor and the cystic fibrosis transmembrane conductance regulator CFTR ; . These two ABC proteins possess an ion channel activity and bind specific sulfonylureas, such as glibenclamide, but homologs have not been identified in plant cells. We recently have shown that there is an ABC protein in guard cells that is involved in the control of stomatal movements and guard cell outward K current. Because the CFTR, a chloride channel, is sensitive to glibenclamide and able to interact with K channels, we investigated its presence in guard cells. Potent CFTR inhibitors, such as glibenclamide and diphenylamine-2-carboxylic acid, triggered stomatal opening in darkness. The guard cell protoplast slow anion current that was recorded using the whole-cell patchclamp technique was inhibited rapidly by glibenclamide in a dose-dependent manner; the concentration producing half-maximum inhibition was at 3 M. Potassium channel openers, which bind to and act through the sulfonylurea receptor in animal cells, completely suppressed the stomatal opening induced by glibenclamide and recovered the glibenclamide-inhibited slow anion current. Abscisic acid is known to regulate slow anion channels and in our study was able to relieve glibenclamide inhibition of slow anion current. Moreover, in epidermal strip bioassays, the stomatal closure triggered by Ca 2 abscisic acid was reversed by glibenclamide. These results suggest that the slow anion channel is an ABC protein or is tightly controlled by such a protein that interacts with the abscisic acid signal transduction pathway in guard cells and glucovance.

World Asthma Day - 2005 World Asthma Day is May 3, 2005. The theme this year is, Unmet Needs of Asthma. It was selected to call the attention of doctors and patients alike to the need for better asthma treatment and management. The Asthma Program distributed a packet of materials to assist local health departments and communities with raising asthma awareness. Some of the activities being planned include school walks, screenings, library events, and press releases. Please inform us as to what activities you conducted. Asthma Action Plans The revised Asthma Action Plans are currently being printed. Ten sample copies accompanied by a letter from the Commissioners of Public Health and Education encouraging the use of AAPs will be mailed to all pulmonologists and allergists, pediatricians, family practice physicians, community health centers, and school-based health centers in the state during the month of May. Copies of the AAP can be obtained upon request from DPH by calling 860-509-7751 or from the ALACT by calling 860-289-5401.
