A 54mg tablet of Concerta, which uses OROS technology. 22% of the drug is contained in the red overcoat, while the remaining 78% is split between two drug layers of differing concentration. The tablet uses an additional push layer that expands as water enters the tablet via the osmotic membrane. The drug is expelled via the laser-drilled hole visible on the left side of the tablet. The osmotic-controlled release oral delivery system (OROS) is an advanced controlled release oral drug delivery system in the form of a rigid tablet with a semi-permeable outer membrane and one or more small laser drilled holes in it. As the tablet passes through the body, water is absorbed through the semipermeable membrane via osmosis, and the resulting osmotic pressure is used to push the active drug through the opening(s) in the tablet. OROS is a trademarked name owned by ALZA Corporation, which pioneered the use of osmotic pumps for oral drug delivery. insulin-dependent diabetes or adult-onset diabetes) commonly begins as insulin resistance, with cells using insulin incorrectly. Gradually, the pancreas loses its ability to produce insulin. According to the National Institutes of Health, 18.2 million Americans (6.3% of the US population) have diabetes. Type 2 diabetes accounts for ~90% to 95% of all diabetes. This disease is associated with obesity, a family history of diabetes, older age, and physical inactivity. Type 2 diabetes also is more prevalent among African Americans, Hispanic/Latino Americans, American Indians, and some Pacific Islander and Asian Americans. Type 2 diabetes has been treated with several antihyperglycemic drugs.
You are right that both of the products that you mentioned are metformin. All of the products are similar in the fact that they are extended release. The whole point of these extended release products is to reduce the gastrointestinal side effects that many patients experience when taking metformin. There are 3 different types of metformin extended release formulations: This metformin product uses what is called a "dual hydrophilic polymer system" as its release mechanism. The outer layer of the tablets contain no drug at all. It's purpose is to completely surround inner polymer particles containing metformin. After the tablet is taken by mouth, the tablet absorbs moisture. The absorbed moisture causes the tablet to swell forming a gel layer on the outside of the tablet. It is this newly formed gel layer that releases metformin into the body at a controlled rate. The peak concentrations of metformin in the body using the dual hydrophilic release polymer mechanism usually ranges anywhere from 4-8 hours. Rarely, too much metformin can build up in the body and cause a serious (sometimes fatal) condition called lactic acidosis. Lactic acidosis is more likely if you are an older adult, if you have kidney or liver disease, dehydration, heart failure, heavy alcohol use, if you have surgery, if you have X-ray or scanning procedures that use iodinated contrast, or if you are using certain drugs. For some conditions, your doctor may tell you to stop taking this medication for a short time. Stop taking this medication and get medical help right away if you have any symptoms of lactic acidosis, such as unusual tiredness, dizziness, severe drowsiness, chills, blue/cold skin, muscle pain, fast/difficult breathing, slow/irregular heartbeat, or stomach pain with nausea/vomiting/diarrhea. Show More Metformin is used with a proper diet and exercise program and possibly with other medications to control high blood sugar. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Metformin works by helping to restore your body's proper response to the insulin you naturally produce. It also decreases the amount of sugar that your liver makes and that your stomach/intestines absorb. Read the Patient Information Leaflet if available from your pharmacist before you start taking metformin and each time you get a refill.
Sep 25, 2017. There are 3 different types of metformin extended release formulations. When water is absorbed in the tablet, the osmotic pressure forces. Metformin HCL is a longstanding, very inexpensive diabetes treatment. And ER stands for “extended release”. There are metformin HCL ER treatments that are.
