Janumet is a prescription tablet used to treat diabetes, made by Merck Sharp and Dohme, or MSD. Its two main active ingredients work by: helping the body to produce insulin; making the body’s cells more receptive insulin; and limiting the amount of glucose made by the liver. The standard course of treatment is one tablet, taken twice a day with or after food.

Type-2 diabetes accounts for an estimated nine tenths of all diabetes cases in the UK. It’s a staggering figure, given that around 3 million people in total are suspected to have diabetes of some form in this country. A progressive condition, type-2 diabetes is slightly different from type-1, in both its biological traits and its onset.
Glucose, which is a type of sugar, is required by the body for regular healthy function. These are absorbed through food in the intestine and produced by the liver, and eventually make their way into the bloodstream. Insulin is a chemical which plays an integral role in extracting these sugars and delivering them to the areas of the body that need them.
Someone with type-1 diabetes will usually not produce any insulin at all, due to the immune system attacking those pancreatic cells which make it; whereas a person with type-2 may generate insulin to a certain extent, but not enough to be able to cope with the amount of glucose in the blood. The onset of type-1 usually takes place during a person’s teenage years, while type-2 is much more likely to manifest in those aged 40 and over.
Causes of the condition are never usually one particular factor. In fact, there are a number of habits and general health traits which might make a person more susceptible to type-2 diabetes. These include having a family history of the condition or being overweight or obese. Persons from certain ethnic background are also more likely to develop the condition. It has a rate of incidence in South Asian and Chinese persons which is higher than that of UK persons, and also higher in persons of Black African or Caribbean origin.
What makes the condition a potentially dangerous one is its gradual nature of commencement. Often, someone with type-2 diabetes might live with the condition for years, before it is discovered. Symptoms include dryness in the eyes, which can induce sight problems of varying degrees; feeling tired; and an increased need or urgency to pass urine. Left untreated, the condition can lead to the development of serious health issues, such as kidney failure and heart disease, so seeking treatment as soon as possible is important.
Upon diagnosis, one of the first things a doctor will address when deciding on the best course of treatment is the patient’s lifestyle. Reducing alcohol intake, stopping smoking, and taking measures to lose weight are also possible courses of action. They may choose to suggest a particular diet plan, and advise a programme of exercise.
In some cases however, the above may not be sufficient enough to slow down the progression of the condition, or bring blood sugar levels under control. Prescription treatment in these instances may be necessary. Janumet is one such treatment, and as a combination medication, this is intended for use in those cases where a single-agent option has not produced the desired results.
The functioning constituents of Janumet are sitagliptin and metformin hydrochloride. Belonging to the biguanide category of drugs, metformin works by: inhibiting the generation of sugar by the liver; increasing the receptiveness of muscular cells to insulin in the body; and decelerates glucal absorption from food in the gut. Sitagliptin is a type of protein inhibitor. Its function is to prevent the breaking down of certain hormones which encourage the pancreas to produce insulin, and to also limit the output of sugar by liver cells.
