What is Ionamin

Phentermine

The Generic name of this drug

Treatment Summary

Phentermine is an anti-obesity drug that works by suppressing the appetite. It was introduced in 1959 and approved by the FDA for short-term weight management. Phentermine was originally offered as a combination drug with fenfluramine and dexfenfluramine, but this was discontinued due to reports of abnormal valves in 30% of consumers. In 2012, phentermine was approved for use alone or in combination with topiramate. It has a low risk of addiction and is classified as Schedule IV drug.

How Ionamin Affects Patients

Phentermine works by suppressing appetite, possibly due to an increase in leptin. It also may increase the amount of energy used when resting. In clinical studies, patients taking phentermine lost an average of 3.6 kg in 2-24 weeks compared to those taking a placebo. Additionally, these patients were able to keep their weight off even after stopping taking the drug. Phentermine is a derivative of the amphetamines, but does not cause any of the amphetamine-related side effects, such as stimulation of the central nervous system, increased blood pressure, or changes in heart rate.

How Ionamin works in the body

Phentermine works by releasing a special chemical called noradrenaline in the brain. This chemical increases the activity of certain receptors, making them more sensitive to energy signals. It also suppresses the hunger signal by reducing the activity of another chemical called neuropeptide Y. Lastly, it has a weak effect on monoamine oxidase, which is a chemical in the brain responsible for breaking down certain chemicals. All of these effects work together to make us feel less hungry and more energized.

Ionamin for Overweight

I've been taking this medication for a while now, and it's really great. I'm a bit heavier than I was in high school, but that's not necessarily a bad thing. My doctor monitors my bloodwork every six months and I haven't had any adverse effects.

Ionamin for Overweight

I had tried to lose weight through diet and exercise after my second baby, but saw no results. A doctor then prescribed this pill to me, and I dropped 30 pounds in three months. I have now been off the pill for five months and have not gained any weight back, which is amazing.

All Sexes
Durham, NC

This project is studying whether a team-based specialty clinic can help people with type 2 diabetes and heart disease better manage their blood pressure and cholesterol. The clinic includes coordinated care from heart doctors, kidney doctors, diabetes specialists, and liver doctors. The study will compare two groups of patients: one receiving usual care from their primary care provider, and one referred to the Duke Cardiometabolic Prevention Clinic for multidisciplinary care. The main goals are to find out if this clinic improves blood pressure and cholesterol control over 12 months, increases use of recommended heart medications, and reduces hospital visits and other healthcare use. Participants will be randomly assigned to one of the two groups. Those referred to the clinic will: 1) Meet with a cardiologist for an initial evaluation. 2) Be referred to other specialists (such as endocrinology, nephrology, or hepatology) based on their needs. 3) Receive ongoing, coordinated care from a team of specialists working together to improve their heart and metabolic health.

Continuous Glucose Monitoring for Diabetes

20 - 60
All Sexes
Baton Rouge, LA

Diabetes represents a significant global health burden, with its prevalence continuously rising and causing extensive impacts on individuals, healthcare systems, and society. The International Diabetes Federation (IDF) Diabetes Atlas 2021 reported a global prevalence of 10.5%, with type 2 diabetes (T2D) comprising approximately 90% of cases. In the US, diabetes prevalence stands at 11.6%, affecting roughly 38.4 million adults, with approximately 1.2 million new diagnoses each year. Obesity, affecting over 42% of US adults-including 9.4% with severe obesity-is recognized as the primary risk factor for diabetes. Severe obesity, present in around 30% of T2D patients, markedly elevates the risk for cardiovascular disease, non-alcoholic fatty liver disease, and other comorbidities, resulting in increased mortality rates. Addressing this burden requires coordinated strategies targeting prevention, early diagnosis, effective treatment, and patient education. However, conventional management methods, such as lifestyle modifications and pharmacotherapy, often result in transient weight loss and temporary diabetes remission, with frequent relapses. In contrast, metabolic surgery, notably Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG), has emerged as a highly effective intervention for significant weight loss and durable diabetes remission, particularly among patients with severe obesity and T2D. These procedures improve metabolic outcomes beyond weight reduction, enhancing insulin sensitivity and glycemic control. Consequently, integrating metabolic surgery into standard diabetes care guidelines and expanding patient access is crucial. Although metabolic surgery outperforms intensive medical therapy, traditional assessment methods, such as HbA1c, have notable limitations. HbA1c measures average glucose levels without capturing short-term fluctuations, glucose variability, or hypoglycemia, limiting its utility post-surgery. Continuous glucose monitoring (CGM) offers real-time, detailed insights into glucose patterns, variability, postprandial excursions, and hypoglycemia, making it highly suitable for postoperative monitoring. CGM provides a clearer picture of immediate and long-term metabolic changes following surgery, allowing early identification of abnormal glycemic patterns influenced by surgical alterations in gastrointestinal anatomy and diet. It enables the detection of post-bariatric hypoglycemia (PBH), a recognized complication following metabolic surgery, and improves understanding of hypoglycemia unawareness-critical for enhancing patient safety and clinical outcomes. However, current research on CGM in metabolic surgery remains limited, primarily consisting of cross-sectional or retrospective studies with small sample sizes, lacking preoperative data, and employing short monitoring periods. Therefore, robust studies such as randomized controlled trials (RCTs) are essential to validate CGM's efficacy and inform its broader adoption in clinical practice.

Support Program for Caregivers of Patients with Cancer and Diabetes

18 - 99
All Sexes
Chapel Hill, NC

This study investigates the feasibility, acceptability, and preliminary efficacy of enCompass Humana, a social support intervention for caregivers of patients with cancer and diabetes. The enCompass program aims to improve support for these caregivers through a randomized feasibility study of a pilot-tested coaching and navigation program. Caregiver services and system-level support are essential, but successful interventions for cancer caregivers are rarely standardized or systematically disseminated. Consequently, many programs do not reach the most underserved caregivers. Challenges to implementation include substantial clinical staff involvement, lack of dissemination and implementation information, and failure to tailor interventions to rural contexts. Despite the lack of standardized supportive interventions, national reports and legislative efforts increasingly recognize the need to support caregivers. Caregivers reported unmet needs in all domains of social support, including instrumental help (e.g., in-home help, housekeeping), logistical and coordination support (e.g., food delivery, accompanying patients to appointments), information about illness and progression, emotional support, self-care guidance, and financial assistance (e.g., parking costs, lost wages). Caregivers show high interest in services but cited uncertainty and lack of strategies for accessing resources. Many are unaware of existing services. Interviews with oncology clinicians and healthcare administrators revealed similar findings: resources exist, but there is no system to match them with caregivers' needs. Preliminary data suggest the intervention improves caregiver coping self-efficacy and reduces anxiety and depression in patients. With input from stakeholders, including caregivers, patients, family caregiving experts, and clinical care experts, the study team adapted the CARING application into enCompass to mitigate structural barriers and normalize support-seeking. The long-term goal is to adapt this psychosocial support program to increase self-efficacy, support-seeking, and reduce loneliness among caregivers. It is hypothesized that enCompass will build self-efficacy and coping skills, serving caregivers throughout the patient's illness and complications.
