Phentermine 37.5 mg capsules vs tablets Sometimes, this has led to the need topiramate treatment in strengths hospital. J Am Med Assoc ; In these topiramate immediate-release weight-loss studies, there were few cardiovascular-related adverse events [7278]. Weight loss may raise and chance of low blood pressure in people who weaknesses treated for high blood pressure. Expert Phentermine Investig Drugs ; List Topiamate Heart Study.

Topiramate may decrease food intake via effects of carbonic-anhydrase inhibition on taste [67,68] , or through its effects on GABA transmission, since GABA-A receptor activation [69] and the interaction between GABA and leptin pathways [70] are known to mediate effects on appetite and metabolism. Topiramate may also affect energy expenditure based on preclinical data [71].

Because weight loss was observed in trials for epilepsy, topiramate immediate-release was evaluated for the treatment of obesity, as well as treatment of hypertension or T2DM in obese patients [7278]. A 6-month, placebo-controlled, randomized trial of obese patients demonstrated weight loss of 2. Doses were gradually increased over 12 weeks and tapered at the end of trial [73]. All topiramate immediate-release doses elicited greater weight loss than placebo [73].

After 44 weeks of treatment, patients treated with topiramate immediate-release had lost In another placebo-controlled, randomized clinical trial of obese patients with hypertension, patients treated with topiramate immediate-release experienced weight loss of 5. Subsequent to these studies of topiramate immediate-release, an extended-release formulation of topiramate was developed potentially to enhance tolerability while simplifying dosing [78] , but this formulation was never submitted for regulatory approval.

Topiramate, like other carbonic anhydrase inhibitors, may produce CNS and peripheral nervous system PNS effects, such as paraesthesias, acute myopia, blurred vision, redness of the sclera, photophobia, and eye discomfort resulting from secondary angle-closure glaucoma, as well as psychiatric and neurologic disturbances, including fatigue, somnolence, depression, and difficulties with concentration and memory [65,66].

Although in-vitro evidence has suggested the potential for topiramate to be arrhythmogenic [79] , data indicate that topiramate does not increase the risk of sudden unexpected death due to cardiac arrhythmia in epilepsy patients [80]. Topiramate is a pregnancy class D compound that carries teratogenic risk, specifically possible risk of craniofacial defects [65,66]. In these topiramate immediate-release weight-loss studies, there were few cardiovascular-related adverse events [7278].

Further, given that topiramate inhibits carbonic anhydrase activity, it is possible that topiramate could elicit a weight loss-independent BP reduction due to mild diuretic effects [82,83]. In this low-dose formulation, phentermine [mean plasma maximum concentration C max In a fourth study, adults with T2DM were evaluated in a week extension of a week double-blind, placebo-controlled phase 2 trial DM; 56 weeks total [88]. In these studies, patients were managed to standard of care for any comorbidity, including medication changes as needed.

All patients received dietary and lifestyle counselling based on the Lifestyle, Exercise, Attitudes, Relationships, Nutrition LEARN programme [91] , including guidance to reduce daily caloric intake by kilocalories, increase water consumption, and increase physical activity [84,86,87]. During the studies, patients with hypertension could be treated initially with antihypertensive therapy, using angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers; if patients were already taking these agents, calcium channel blockers, beta blockers, or thiazide diuretics could be added [92].

Similarly, patients with T2DM or dyslipidaemia could also have their medications adjusted to achieve standard of care [92]. Antidepressant medications selective-serotonin receptor inhibitors, serotonin-norepinephrine receptor inhibitors, and bupropion but not tricyclics or monoamine oxidase inhibitors were allowed if the dose had been stable for at least 3 months [84,86,87].

Similarly, patients showed significant, sustained percentage and categorical weight loss through weeks in the 2-year cohort of the SEQUEL extension study [87]. Changes in a blood pressure, b heart rate, and c rate pressure product from baseline to week 56 1-year cohort; safety set [88,89]. Rate pressure product was defined as the product of the heart rate and SBP, divided by This cardiovascular effects analysis includes patients with baseline and endpoint measurements.

Effects on heart rate at week 56 based on baseline heart rate 1-year cohort; safety set [88]. The slight mean increases in heart rate vs. Increased myocardial oxygen demand is the putative mechanism by which increased heart rate promotes cardiac ischaemia in patients with macrovascular or microvascular coronary disease [94]. Change in blood pressure, heart rate, and rate pressure product in patients with hypertension at baseline 1-year cohort; safety set [92].

Adverse events were generally dose-related and mild to moderate in severity, occurring mostly during the titration period [26,84,8688]. Cardiac arrhythmia-related adverse events reported by patients as defined by mapping to the Medical Dictionary for Regulatory Activities Cardiac Disorders System Organ Class were palpitations, increased heart rate, and tachycardia, and occurred in between 0. There were low rates of serious adverse events classified as cardiac disorders [92].

Within the 1-year safety cohort, A cardiovascular outcomes trial is planned by the drug's manufacturer, in accordance with one of the US FDA's post-marketing study requirements [95]. Incidence rates for cardiovascular event outcomes MACE endpoints; all exposed patients [92]. There is a current unmet need for an effective weight-loss pharmacotherapy that can be used for long term for the many patients unable to attain or to maintain weight loss through dietary interventions and exercise. Given the increased cardiovascular and metabolic risk in this patient population, obesity pharmacotherapies must present minimal unwanted or adverse cardiovascular risks, which if present, should be outweighed by their other cardiovascular-related benefits.

However, the treatment is not without side effects. For example, the topiramate extended-release component can induce paraesthesia and taste change, likely through carbonic anhydrase inhibition. Topiramate cannot be used by pregnant women due to teratogenic risks. The phentermine component can produce adrenergic symptoms, such as dry mouth. We would like to acknowledge and thank The Lockwood Group for editorial assistance.

This review showed that combining low doses of phentermine and topiramate for the treatment of obesity minimized side effects while maintained weight loss efficacy. The side effects were paraesthesia, taste changes and dry mouth. Weight loss induced by the combination was associated with improved BP through one and two years of treatment. A small, usually transient increase in heart rate was observed. However, reductions in BP and rate pressure product were seen suggesting that when used in conjunction with lifestyle modifications, the combination may represent a safe and effective therapy for the management of obesity.

A large multinational trial concerning cardiovascular outcomes is ongoing. Combination drug treatment based on phentermine and topiramate has been recently approved by the FDA for the treatment of overweight and obesity. The paper by Jordan et al. The information available so far on the impact the drug has on cardiovascular events limited at present at the one year follow-up confirms the favourable effects the drug has on cardiovascular risk. BP, blood pressure; b. National Center for Biotechnology Information , U.

Abstract Weight loss can reduce the increased cardiovascular risk associated with obesity. Agent Year s History of cardiovascular effects Dinitrophenol s Affected mitochondrial oxidative phosphorylation to induce weight loss, and was associated with elevated body temperature [27,39]. Amphetamines s Linked to increased risk of hypertension and pulmonary hypertension [29].

Phentermine till present The European Commission withdrew marketing authorization for all weight-loss drugs phentermine, amfepramone, and mazindol from the market due to unfavourable risk-to-benefits ratio. The licence was withdrawn and then subsequently reinstated several times [38] , but a decision in by the European Court of First Instance overturned previous decisions to withdraw marketing authorizations for phentermine [37].

Phentermine is eligible for marketing authorization, but would require an updated application to be submitted. Fenfluramine and dexfenfluramine Fenfluramine: Aminorex An amphetamine analogue, withdrawn due to risks of pulmonary hypertension [27]. Sibutramine Norepinephrine and serotonin-reuptake inhibitor was approved for treating obesity in the US and in Europe. Due to increased SBP, DBP, and pulse, caution was recommended in people with poorly controlled hypertension or history of cardiovascular arterial disease, stroke, or arrhythmia hyperthermia [27,39].
