The pharmaceutical drug phentermine is an amphetamine replacement that is used to treat obesity. It falls under a class of drugs known as appetite suppressants. Exogenous obesity results from consuming more food than the body’s activity level requires, leading to increased fat storage. In the United States, where one in three people is considered fat and over two-thirds of adults are overweight or obese, this condition has reached epidemic proportions. The prevalence of obesity has nearly doubled worldwide. Phentermine is typically prescribed for short-term use in conjunction with exercise, a reduced-calorie diet, and behavioral modifications. It is designed to treat exogenous obesity in individuals with a baseline body mass index (BMI) of greater than 30 kg/m2 or larger than 27 kg/m2 when there are additional risk factors present, such as managed hypertension, diabetes, or hyperlipidemia.
Phentermine: Fat Reduction Facilitator
Phentermine functions as a fat-reduction facilitator primarily by suppressing appetite and enhancing metabolism. As an appetite suppressant, it acts on the central nervous system to reduce feelings of hunger, which helps individuals consume fewer calories and resist overeating. By curbing appetite, it becomes easier for people to adhere to a reduced-calorie diet. Moreover, phentermine stimulates the release of norepinephrine, a neurotransmitter that boosts metabolism and increases the body’s energy expenditure. This heightened metabolic rate promotes fat burning, leading to a decrease in overall body fat. The efficiency of phentermine lies in its ability to support individuals in achieving their weight loss goals when used as part of a comprehensive regimen that includes exercise, behavioral modifications, and caloric restriction. It is most effective in the management of exogenous obesity with additional risk factors such as controlled hypertension, diabetes, or hyperlipidemia.
Appetite Suppressing Quality
Phentermine is a sympathomimetic amine, which means it acts similarly to the body’s natural “fight or flight” response by stimulating the release of certain neurotransmitters, mainly norepinephrine and dopamine. Upon administration, phentermine prompts the release of norepinephrine from nerve terminals in the brain. Norepinephrine is a neurotransmitter that signals the “fight or flight” response, leading to reduced feelings of hunger. By increasing norepinephrine levels, phentermine creates a sense of satiety or fullness, making it easier for individuals to control their food intake.
Phentermine also affects the release of another neurotransmitter called neuropeptide Y (NPY), which is known to stimulate appetite. By inhibiting the release of NPY, phentermine further reduces the sensation of hunger, helping individuals to resist the urge to eat excessively. In addition to its impact on norepinephrine and NPY, phentermine influences serotonin levels in the brain. Serotonin is a neurotransmitter associated with mood regulation and feelings of well-being. By increasing serotonin levels, phentermine may contribute to improved mood and a decreased inclination towards emotional eating. Phentermine may enhance the body’s sensitivity to leptin, a hormone produced by fat cells that signals the brain when we are full. Increased sensitivity to leptin helps individuals recognize satiety cues more effectively, further reducing appetite and promoting weight loss.
Metabolic Risk Minimizer
Phentermine often offers certain metabolic benefits that can help reduce the risk factors associated with certain medical conditions, particularly in the context of obesity management. While its primary function is to aid weight loss by suppressing appetite, phentermine’s effects on metabolism contribute to its role as a metabolic risk minimizer. Here’s how:
- Improved Insulin Sensitivity: Studies have shown that phentermine can enhance insulin sensitivity. The term “insulin sensitivity” describes how well the body’s cells react to insulin, the hormone in charge of controlling blood sugar levels. For people with insulin resistance, a disease frequently linked to obesity, improved insulin sensitivity may be advantageous as it lowers the chance of developing type 2 diabetes.
- Blood Pressure Regulation: Systolic blood pressure is the highest number in a blood pressure reading, and phentermine has been proven to induce a mild reduction in this number. Blood pressure reduction can lessen the risk of hypertension and associated cardiovascular issues.
- Lipid Profile Improvement: Phentermine has been associated with favorable changes in lipid profiles, including reductions in total cholesterol, LDL cholesterol (often referred to as “bad” cholesterol), and triglycerides. These improvements can help lower the risk of atherosclerosis and cardiovascular diseases.
- Inflammation Reduction: Obesity is often accompanied by chronic low-grade inflammation, which can contribute to metabolic dysfunction and increase the risk of various health issues. Some studies suggest that phentermine may have anti-inflammatory effects, which could help reduce the overall inflammatory burden in obese individuals.
Dosage and Handling Protocol
Phentermine is typically available in different forms, including immediate-release tablets and capsules, as well as extended-release capsules. The specific dosage and dosing frequency may vary depending on the formulation and the individual’s medical condition. Generally, the recommended starting dose of immediate-release phentermine for adults is 15 to 37.5 mg per day, usually taken before breakfast or 1-2 hours after breakfast. Extended-release capsules are typically prescribed at a dosage of 15 to 30 mg once daily, usually taken before breakfast.
Usually, phentermine is taken in the morning, either right before breakfast or around an hour or so after. Because of its stimulant-like properties, taking it later in the day may result in insomnia or other sleep disruptions, which can be avoided by taking it in the morning. Avoid taking phentermine right before night to prevent disruption of sleep patterns. Late-night dosages may cause trouble falling asleep or interrupted sleep, both of which can have an adverse effect on general health and well-being.
