Composition and form of release
Siofor’s active ingredient is metformin hydrochloride. It is produced in tablet form, in dosages of  1000 mg.
Siofor is one of the most popular medicines in the world, which is used to treat type II diabetes mellitus. A hypoglycemic drug belongs to the group of antidiabetic drugs (drugs to combat diabetes mellitus) of type II, non-insulin dependent. It is also effective in diabetes complicated by obesity, especially if diet does not help.
Siofor’s active ingredient – metformin – not only does not affect the amount of insulin in the blood, but also changes its quality. It has the ability to influence the mechanism for stimulating glucose uptake in muscle and adipose tissue.
It also increases blood circulation in the liver by accelerating the conversion of glucose to glycogen. Has the ability to induce a mild appetite-reducing effect (anorexigenicity), helping patients to follow a diet and slowing down the absorption of carbohydrates.
Cannot be prescribed if the patient consumes less than 1,000 kilocalories per day.
It is forbidden to take with type I diabetes mellitus (insulin dependent), because when taken simultaneously with insulin, it can cause hypoglycemia, coma. It will also have no effect on completely stopping insulin production in type II diabetes. It is contraindicated to use if the patient has symptoms of diabetic ketoacidosis, diabetic precoma, coma, myocardial infarction, heart failure, severe infections, impaired liver and kidney function, lung diseases, operations and injuries, catabolic diseases, the presence of tumors of various etiologies, alcoholism, and, of course , if you are allergic to metmorphine.
