What is the connection between warfarin and INR?
medicines called warfarin and INR or international normalized ratio are connected because people who use the drug need regular INR values. Warfarin is a cure of curse, which has a so -called narrow therapeutic index. This means that it can be easy to exceed the recommended amount, especially because the drug is extremely reactive and carries the risk of excessive bleeding. Information from INR tells doctors whether patients are taking a safe and appropriate amount of drug. The INR is simply the application of the mathematical formula on the PT. It helps normalize the results at international level, as these can be slightly affected by testing materials and manufacturer. Both test names may be suitable and both terms are often used interchangeably. The only noticeable difference between INR and PT is Whether results are normalized; The blood test itself, which can be performed on a finger or blood collection, is the same.
As already mentioned, warfarin is a reactionTent and has a narrow therapeutic index. It prevents clotting by inhibiting vitamin K and in individuals who irregularly consume vitamin K foods such as leaf green vegetables that can reduce the drug. Alternatively, many types of medicinal products and even viruses or infections can amplify the effects of warfarin and endanger the risk of excessive bleeding. The amount of things that can affect the effectiveness of the drug means that there is an undeniable connection between warfarin and INR readings. Giving drugs without testing is medically sloppy because there is no way to find out whether it is used too much or too little.
Most people discover this connection during regular visits to the laboratory or anticoagulant clinic. The clinics are often preferred because medical staff is at hand to make the recommended dosage adjustments immediately through PT/INR interpretation. Of course, clinics are not the only place to test; People can be tested in hospitals, in a medical officeor in their homes with a special separate device. Home tests can be a safer option if a person has shown previous volatility in PT subtraction.
The most important way of warfarin and INR relate to each other because the results provided to the test doctors tell whether patients need to increase or reduce their dose. Individuals need blood clotting times to be in a specific range, such as 2.0 to 3.0 seconds, which is defined by the treated health condition. If a blood clot is in a shorter time, a higher dose of warfarin is given. Longer precipitation time is translated into a dose reduction.
The first few months of warfarin therapy is often the most critical period. The individual's reaction to the thickness is unpredictable and the levels of drugs must slowly increase. This means that patients may require numerous INR values. Because the reaction to the drug stabilizes, tests can be performed less frequently. This could change if the patient gets ill, pIt grows new drugs or makes sudden and dramatic diet changes.
