Tolerabilitet

Tolerabilitet refers to the degree to which a drug or other substance can be accepted by an individual without causing undesirable effects. It is a crucial aspect of drug development and clinical practice, impacting patient adherence and treatment outcomes. The concept of tolerability encompasses not only the absence of severe adverse reactions but also the presence of milder, bothersome symptoms that can nevertheless affect a person's quality of life and willingness to continue a therapeutic regimen.

Factors influencing tolerability are diverse and can include the inherent properties of the substance, the dosage, the route of administration, and individual patient characteristics such as age, genetics, and co-existing medical conditions. For example, a medication that is well-tolerated at a low dose might become poorly tolerated at a higher dose. Similarly, individuals may react differently to the same drug due to variations in their metabolism or immune system.

Assessing tolerability typically involves monitoring patients for side effects, both subjective and objective. This can be done through patient self-reporting, clinical examinations, and laboratory tests. A favorable tolerability profile is often a key determinant in the selection of one treatment over another, especially when multiple therapeutic options exist with similar efficacy. Ultimately, tolerability aims to balance the therapeutic benefits of an intervention with its potential burdens on the patient.
