Glimepiride, commercialized in Belgium under the trade name of Amarylle by Aventis, is a new sulphonylurea compound which is indicated in the treatment of type 2 diabetes, after diet and exercise failure. It is available as 2 mg tablets. The initial doses is 1 mg, to be progressively increased up to 4 mg per day, if necessary, with a maximal daily dose of 6 mg. It is recommended to take glimepiride once a day, with the first main meal. Because of a particular binding of this sulphonylurea to the B cells of Langerhans pancreatic islets and, perhaps, of the presence of some extrapancreatic effects, both hypoglycaemic risk and circulating plasma insulin levels are lower with glimepiride than with glibenclamide, the reference sulphonylurea agent used in comparative clinical trials.

Repaglinide (NovoNorm) is an antidiabetic oral agent of the new glinide class with insulinotropic activity. Its action on insulin secretion is more rapid and shorter than that of sulphonylurea compounds. Thanks to these properties, repaglinide is able to better control postprandial hyperglycaemia and is associated with a lower risk of delayed hypoglycaemic episodes. It is indicated for the treatment of type 2 (non-insulin-dependent) diabetes mellitus as monotherapy, after diet failure, or in combination with metformin, when the biguanide is insufficient. NovoNorm is commercialized as tablets of 0.5, 1 and 2 mg, to be taken just before each meal. Initial dosis should be 0.5 mg before meal in diabetic patients on diet alone or 1 mg before meal in patients already receiving an hypoglycaemic agent. If necessary, the dosis should be progressively increased, depending on the individual response, up to 4 mg before meal (maximal daily dosage of 16 mg), in order to optimize blood glucose control.

Rofecoxib (Vioxx, Merck Sharp & Dohme) is a potent and selective inhibitor of the COX-2 isoform of cyclooxygenase which is used as a nonsteroidal anti-inflammatory drug (NSAID). It is indicated in the symptomatic relief of pain due to osteoarthritis. The initial oral dosage of rofecoxib is 12.5 mg once daily in adults, and this dose may be increased up to a maximal dosage of 25 mg once daily if necessary. Its clinical efficacy seems to be similar to that of other NSAIDs at maximal recommended dosages, but its safety profile, especially gastrointestinal tolerance, is much better because of the COX-2 selectivity. Ongoing clinical trials are performed in patients with rheumatoid arthritis. [less ▲]

Premelle, commercialised by Wyeth-Lederle, is a combination of conjugated estrogens 0.625 mg and medroxyprogesterone acetate 5 mg which is indicated in the treatment of menopause-associated problems, among which vasomotor symptoms, atrophic vaginitis and/or urethritis, and in the prevention and treatment of post-menopausal osteoporosis. It is presented in two formulations, Premelle cyclic 5 and Premelle 5. The former, in which the progestagen is only given during the last 14 out of 28 days of the treatment cycle, is accompanied by regular bleeding and thus preferably indicated during perimenopause whereas the latter, in which the progestagen is given continuously and results in amenorrhea, is mostly indicated after menopause in order to improve long-term compliance.

Osteoarthritis (OA) is one of the most common chronic musculoskeletal diseases and causes of lameness in the dogs. The osteoarthritic disease process involves the entire synovial joint, encompassing the synovium, cartilage and underlying bone. Joint failure results from an abnormal mechanical strain causing damage to normal tissue or failure of pathologically impaired articular cartilage and bone under the influence of normal physiological strain or a combination of both. In both cases, the end point is cartilage loss and joint impairment. Osteoarthritic chondrocytes show an altered phenotype characterised by an excess production of catabolic factors, including metalloproteinases and reactive oxygen species. These factors constitute potential therapeutic targets and some new drugs and nutraceuticals have been proposed to promote the return to homeostasis. Until now, the therapeutic management of OA in dogs has been dominated by nonsteroidal anti-inflammatory drugs, but some new compounds, including diacerhein, with potential structure-modifying effects, are already used to treat OA in humans and could be helpful to manage OA in the dog. In addition, novel nutraceuticals, such as avocado/soybean unsaponifiable substances, have shown symptomatic effects in knee OA in humans, and could offer an alternative to prevent OA progression. This paper provides an overview of recent discoveries in the pathophysiology and in the therapeutic management of osteoarthritis in dogs. (c) 2004 Elsevier Ltd. All rights reserved. [less ▲]

The demonstration that stains reduce the risk of cardiovascular diseases, in both secondary and primary prevention trials, led to the recent publication of sophisticated pharmaco-economical studies. A lot of factors may influence the cost-effectiveness ratio of the pharmacological intervention, especially the mode of calculation of various costs, the initial level of cardiovascular risk of the patients and the medico-economical particularities of each country. What so ever, available studies appear to justify the use of statins in secondary prevention, i.e. in coronary patients, even those with only a moderate hypercholesterolaemia, and, in primary prevention, i.e in hypercholesterolaemia individuals with obvious high risk of cardiovascular disease.

Type 2 diabetes has long been considered as a benign disease, whereas it is in fact associated with an enormous socio-economic cost. The major part of the burden of diabetes results from the management of complications (both direct and indirect costs), rather than from the various components of the antihyperglycaemic treatment itself. Solutions include a better prevention of the disease, an earlier diagnosis among individuals at risk, and an optimized management of diabetes, particularly in primary care settings, in order to avoid or retard the development of severe micro- or macroangiopathic complications which are particularly expensive.

Continuous subcutaneous insulin infusion is characterized by a basal insulin delivery rate to which insulin boluses are added. The basal delivery rate maintains a small insulin reserve in the local subcutaneous depot. This reserve averages 2 to 5 times the hourly basal rate at the steady-state which is reached after about 7 hours but depends on numerous factors: subcutaneous blood flow, skinfold thickness, insulin concentration, etc. It explains the pharmacokinetics time-lag of the system, more particularly the similar effects of a basal rate delivered in either a pulsatile/intermittent or a continuous manner, the lack of deleterious effect of a 1-h pump arrest, the 2-h delay before significant metabolic deterioration during a more prolonged interruption of the infusion, the delayed plasma insulin changes when the basal insulin delivery rate is doubled or reduced by half, etc. Insulin boluses pharmacokinetics is not fundamentally different from that of soluble insulin injection in conventional therapy. As an example, insulin boluses should ideally be given 30 min before the meals in order to better prevent post-prandial hyperglycaemia. However, the absence of intermediate zinc-insulin in the system may result in an earlier increase of plasma free insulin levels, which for instance allows a rapid correction of the metabolic alterations induced by a prolonged interruption of the basal infusion rate. This kinetics does not seem to be significantly altered by insulin concentration nor by the profile of the bolus but is affected by the insulin content of the subcutaneous depot at the time the bolus is delivered.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

17beta-Estradiol (E2) exerts negative feedback effects at the hypothalamo-pituitary level on serum FSH. This study investigated the effects of repeated daily administration of intranasal E2 (S21400) on the pharmacokinetics (PK) of E2 and estrone (E1) and the pharmacodynamics (PD) of FSH and assessed the PK/PD relationship between E2 and FSH using population model-dependent analysis. Postmenopausal volunteers (n = 24) received according to a balanced cross-over design, two 28-d treatments separated by a 2-month wash-out period: 300 mug E2, either alone or combined with oral dydrogesterone (20 mg/d) during the last 14 d of one of the treatments. Absorption of E2 was rapid, with maximal plasma concentrations at 10-30 min, returning to postmenopausal levels within 12 h. Over the 24-h period, FSH levels showed a U curve, with a minimum around 8 h after E2 administration. Moreover, over the treatment period, FSH basal values decreased by 17% between d 1 and 14 and an additional 5% between d 14 and 28. A PK/PD model described these short- and mid-term effects, possibly reflecting separate regulation mechanisms by E2 on FSH release and biosynthesis, respectively. The administration of progestin had no influence on E1, E2, and FSH model parameters. This study suggests that daily transient tissue exposure to E2 after pulsed estrogen therapy elicits short- and mid-term effects on the gonadotropin axis. [less ▲]

Inhibitors of sodium-glucose co-transporter type 2 (SGLT2) are proposed as a novel approach for the management of type 2 diabetes mellitus (T2DM). Several compounds are already available in many countries (dapagliflozin, canagliflozin, empagliflozin and ipragliflozin) and some others are in a late phase of development. The available SGLT2 inhibitors share similar pharmacokinetic characteristics, with a rapid oral absorption, a long elimination half-life allowing once-daily administration, an extensive hepatic metabolism mainly via glucuronidation to inactive metabolites, the absence of clinically relevant drug-drug interactions and a low renal elimination as parent drug. SGLT2 co-transporters are responsible for reabsorption of most (90 %) of the glucose filtered by the kidneys. The pharmacological inhibition of SGLT2 co-transporters reduces hyperglycaemia by decreasing renal glucose threshold and thereby increasing urinary glucose excretion. The amount of glucose excreted in the urine depends on both the level of hyperglycaemia and the glomerular filtration rate. Results of numerous placebo-controlled randomised clinical trials of 12-104 weeks duration have shown significant reductions in glycated haemoglobin (HbA1c), resulting in a significant increase in the proportion of patients reaching HbA1c targets, and a significant lowering of fasting plasma glucose when SGLT2 inhibitors were administered as monotherapy or in addition to other glucose-lowering therapies including insulin in patients with T2DM. In head-to-head trials of up to 2 years, SGLT2 inhibitors exerted similar glucose-lowering activity to metformin, sulphonylureas or sitagliptin. The durability of the glucose-lowering effect of SGLT2 inhibitors appears to be better; however, this remains to be more extensively investigated. The risk of hypoglycaemia was much lower with SGLT2 inhibitors than with sulphonylureas and was similarly low as that reported with metformin, pioglitazone or sitagliptin. Increased renal glucose elimination also assists weight loss and could help to reduce blood pressure. Both effects were very consistent across the trials and they represent some advantages for SGLT2 inhibitors when compared with other oral glucose-lowering agents. The pharmacodynamic response to SGLT2 inhibitors declines with increasing severity of renal impairment, and prescribing information for each SGLT2 inhibitor should be consulted regarding dosage adjustments or restrictions in moderate to severe renal dysfunction. Caution is also recommended in the elderly population because of a higher risk of renal impairment, orthostatic hypotension and dehydration, even if the absence of hypoglycaemia represents an obvious advantage in this population. The overall effect of SGLT2 inhibitors on the risk of cardiovascular disease is unknown and will be evaluated in several ongoing prospective placebo-controlled trials with cardiovascular outcomes. The impact of SGLT2 inhibitors on renal function and their potential to influence the course of diabetic nephropathy also deserve more attention. SGLT2 inhibitors are generally well-tolerated. The most frequently reported adverse events are female genital mycotic infections, while urinary tract infections are less commonly observed and generally benign. In conclusion, with their unique mechanism of action that is independent of insulin secretion and action, SGLT2 inhibitors are a useful addition to the therapeutic options available for the management of T2DM at any stage in the natural history of the disease. Although SGLT2 inhibitors have already been extensively investigated, further studies should even better delineate the best place of these new glucose-lowering agents in the already rich armamentarium for the management of T2DM.
