The data do not allow the formulation of firm recommendations for carotid endarterectomy in patients who have moderately severe symptomatic carotid stenosis or for patients who have asymptomatic carotid stenosis. In the NASCET 35 ; , patients with symptomatic moderate 50% to 69% ; carotid stenosis treated surgically had a five-year ipsilateral stroke risk of 15.7%; for patients treated medically the risk was 22.2% P 0.045 ; . In other words, 15 patients would need to be treated by endarterectomy to prevent one ipsilateral stroke at five years which is about double the figure for patients with symptomatic, 70% to 99% stenosis ; . Benefit was greatest among men, patients with recent stroke rather than TIA ; as the qualifying event and patients with hemispheric rather than retinal ; symptoms. Data from the trial also indicated that no net benefit accrues from endarterectomy for symptomatic, moderately severe carotid stenosis if the perioperative risk of disabling stroke and death exceeds 2%. A systematic review 41 ; of the randomized trials of carotid endarterectomy for asymptomatic carotid stenosis of 50% or more showed that about 50 patients would have to undergo surgery to prevent one ipsilateral stroke over three years. The Canadian Stroke Consortium does not recommends screening and endarterectomy for asymptomatic carotid stenosis 42 ; . The Canadian Neurosurgical Society considers asymptomatic carotid stenosis of more than 60% to be an "uncertain indication" for endarterectomy 39 ; . The Asymptomatic Carotid Surgery Trial 43, 44 ; in progress ; is anticipated to help clarify the role of endarterectomy in this patient population. Additional studies are required to determine the role of the operation in patients with carotid stenosis who require major surgery below the neck.

Case Scenario: Mrs DM, a 67-year-old woman weight 70 kg, ideal body weight 65 kg ; , presents with poorly controlled diabetes mellitus A1c 8.4% ; . She is currently treated with glyburide 10 mg by mouth twice per day. Her past medical history is significant for myocardial infarction complicated by congestive heart failure 1 year ago symptoms now stable ; . Her medications include: glyburide 10 mg twice per day, gemfibrozil 600 mg twice per day, ramipril 10 mg once per day, aspirin 81 mg once per day, Furosemide 40 mg once per day. Mnemonic Components Indication Case Example Description Treatment is indicated to achieve optimal control of glycemia of an A1c 7%. In this case, the patient is currently taking glyburide at a maximum dose, and combination therapy is recommended from clinical practice guidelines, along with lifestyle changes. Information such as this can be found in recent evidence-based clinical practice guidelines on diabetes mellitus.11-13 ; Potential therapeutic available alternatives to choose from include: biguanides eg, metformin ; glitazones eg, pioglitazone, rosiglitazone ; -glucosidase inhibitors eg, acarbose ; insulin secretagogues eg, nateglinide, repeglinide ; insulin Due to this patient's history of congestive heart failure, one can eliminate glitazones as a potential choice.12, 16, 17 Potential Resource Type Evidence from clinical trials Evidence-based clinical practice guidelines Evidence from systematic reviews including Cochrane reviews14 or Clinical Evidence reviews15 and nortriptyline.

Knowledge of the residual effects of hypnotics on driving ability is of great importance, since these drugs are among the most frequently used psychoactive medications. Moreover, driving is a common daily activity. Unfortunately, residual effects of hypnotics such as sleepiness and reduced alertness may limit the capability of operating a vehicle. The primary evidence presented in this review comes from on-the-road driving tests. The sulfonylureas, available since the 1950s, increase insulin secretion, thereby reducing glucose and A1c levels. These drugs may cause low blood sugar and weight gain. The meglitinides nateglinire and repaglinide ; act in a similar manner as the sulfonylureas by increasing insulin secretions from existing beta cells in the pancrease. Like the sulfonylureas, these drugs may cause low blood sugar and weight gain. The biguanides metformin ; decrease glucose production. Metformin lowers glucose and A1c levels but causes no low blood sugar reactions when used alone. They are not associated with weight gain. Their major limitation is gastrointestinal side effects, such as nausea and diarrhea. However, they are contraindicated in people with kidney disease due to the risk of lactic acidosis. The thiazolidinediones pioglitazone and rosiglitazone ; reduce insulin resistance and lower glucose and A1C levels. They are not associated with hypoglycemia when used alone but are linked to weight gain and edema. They do require monitoring of liver function. These drugs also have a tendency to cause salt and water retention and should not be used in people with heart failure. The a-glycosidase inhibitors acarbose ; delay food absorption as well as the influx of sugar into the bloodstream. They are modestly effective in reducing blood sugar levels but are limited in their application by gastrointestinal side effects such as diarrhea and flatulence. Insulin analogs have been effective for Type 1 and are effective for Type 2 diabetes. Inhaled insulin is on the horizon. Discussion on clinical efficacy From dose-ranging trials, 60 mg appeared to be the minimal effective dose and 180 mg the maximal effective dose. The methodology used in the clinical trials was appropriate. The ITT population include patients who all randomised patients with at least one post-baseline efficacy evaluation; this may have introduce a bias but fortunately the number of patients excluded before providing efficacy data was low and hence the bias is considered unimportant. Adjustment for multiple comparisons was used but as most comparisons made were significant, multiple comparison was not a problem and interpretation of raw p values is safe. As monotherapy, nateglinide efficacy 60 to 180 mg tid ; was significantly greater than placebo with evidence of dose response. The 120-mg dose of nateglinide was found to be superior to the 60 mg, but in one out of 2 studies, the 180-mg dose did not lead to greater reductions in HbA1c compared to 120 mg. Nateblinide monotherapy decreased HbA1c % ; by 0.45-1.02 after 16 or 24 weeks of treatment compared to placebo. Nateglinixe 120 mg tid ; was clearly less effective than metformin 500 mg tid in patients treated by diet only. Nateblinide appears to be more effective than glibenclamide although the comparison was only made on PPGE only and not on HbA1c. No adequate study was performed comparing nateglinide with other SUs. Nategoinide was not compared to repaglinide or an alpha-glucosidase inhibitor. The glycaemic control of patients stabilised on SUs worsened when switched on nateglinide. Overall, the efficacy of nateglinide as monotherapy was less than that of both reference products used as first line therapy in type 2 diabetes. Monotherapy results suggested loss of effect over time especially on FPG, in study B302, 354 and extension B351 ; after initial improvement. In combination in patients not adequately controlled on metformin monotherapy, the addition of nateglinide 60 mg or 120 mg tid ; produced a significant decrease in HbA1c compared to metformin monotherapy. In patients previously treated with SUs, nateglinide 120 mg tid ; combined with glibenclamide did not improve HbA1c. The absence of additive effect may be expected as these two compounds share the same mechanism of action. In patients previously treated with a metformin and glibenclamide combination, the switch from glibenclamide to nateglinide 60 mg, or 120 mg led to a deterioration of glycaemic control in all treatment groups. The combination of nateglinide 120 mg tid ; with troglitazone resulted in a synergistic effect on HbA1c. However, troglitazone is not marketed in Europe and has been withdrawn from the US market because of hepatic toxicity. The combination of metformin and nateglinide has not been compared to the widely used combination of metformin and SU in patients not adequately controlled on metformin monotherapy. This was not requested by the CPMP in their scientific advice of April 1996. Clinical safety Patient exposure The safety analysis was performed on a total of 3156 patients, including all patients randomised in clinical data available with safety assessment post baseline, as of 30 June 1999. This does not include the placebo-controlled study B356 and ongoing clinical trials. To help prevent and manage asthma correctly, see page 167. Persons who suffer from asthma should keep asthma medicines at home. Start using them at the first sign of wheeze or chest tightness. Give every 6 hours: adults: 2 tablets children 7 to 12 years: 1 tablet children under 7 years: tablet babies: DO NOT GIVE In severe cases or if asthma is not controlled with the above dosage, double this dosage may be given, but no more. If the patient cannot talk, seek medical help fast.
