biohasznosulhatóság

Biohasznosulhatóság is a Hungarian term that translates to bioavailability. It refers to the degree and rate at which a substance is absorbed into a living system and becomes available at the site of action. In pharmacology, it is particularly important when considering the administration of drugs. Bioavailability measures how much of a drug reaches the bloodstream and can exert its intended therapeutic effect. Factors influencing bioavailability include the route of administration (e.g., oral, intravenous, topical), the drug's formulation, and the physiological characteristics of the individual.

For orally administered drugs, bioavailability is often less than 100% due to factors like incomplete absorption from the gastrointestinal tract and first-pass metabolism in the liver. Intravenous administration, on the other hand, typically results in 100% bioavailability as the drug enters the bloodstream directly. Understanding bioavailability is crucial for determining appropriate drug dosages and predicting therapeutic outcomes. It helps in comparing different pharmaceutical formulations of the same drug and ensuring consistent treatment efficacy.

Beyond pharmaceuticals, the concept of biohasznosulhatóság is also applied in other fields, such as toxicology and nutrition. In toxicology, it describes the extent to which a toxic substance is absorbed and distributed within the body, influencing its potential harm. In nutrition, it relates to how well nutrients from food are absorbed and utilized by the body. Therefore, biohasznosulhatóság is a fundamental concept that describes the accessibility of a substance for biological processes.
