Is Duromine a Prescription Drug? As a Phentermine containing medication, yes, Duromine is a prescription drug. In Australia it has S4 legal status, which defines it as a prescription medicine obtained from a pharmacy only with a valid prescription given by a medical practitioner only. It should be added that the scheduling process each and every drug is subjected to is being constantly reviewed, and the only authorized body that can do it is The Standard for the Uniform Scheduling of Medicines and Poisons (SUSMP). This means that the legal status of Duromine is not something permanent; the organization can change it any time. For the moment, however, it is Schedule 4. Duromine Pharmacologically A major ingredient of Duromine is Phentermine. Phentermine is a psychostimulant drug that, owing to its appetite suppressing properties, is prescribed for treatment of excess weight as a medical aspect of the entire weight loss program. Two other aspects are a healthy, balanced diet and regular physical exercises. Pharmacologically Phentermine is similar to Amphetamine, which is why it belongs to the class of substituted amphetamines. Similarly to Amphetamine, Phentermine acts as an agent releasing such chemicals as norepinephrine, epinephrine, dopamine and serotonin. Such an effect results in reduction of perception of hunger on the one hand, and breaking down of the stored fat, on the other. Basically, the drug suppresses your food cravings, which when supported with a healthy diet and regular training helps lose weight. Currently there are around 30 brand-name drugs including Duromine which major ingredient is Phentermine. Released onto the market more than 50 years ago, Phentermine has remained one of major weight loss medications during all these years. And when it was classified as a controlled substance and became available through a prescription only, it didn’t lose its status of high-quality and effective anorexiant prescribed when excess weight (severe obesity in most cases) was associated with comorbidities. Duromine: Legal and Marketing Status As we’ve said, currently Duromine is a prescription drug. Mostly it is connected with the amphetamine related nature of Phentermine rather than potentially caused side effects. Of course, the latter is the factor to consider too, the risk of experiencing any is small enough.
