D50 – 50% dextrose in water; The percentage is a mass concentration, so a 5% glucose/dextrose solution contains 50 g/L of glucose/dextrose (5 g per 100 ml). This usage is imprecise but widely used, as discussed at Mass concentration (chemistry) § Usage in biology. Glucose provides energy 4 kcal/gram, so a 5% glucose solution provides 0.2 ...
D50 in medicine is the half-maximal dose: the dose that produces 50% of the maximum response. [1] It may specifically refer to the radiation dose required to achieve a 50% tumor control probability .
D50, the mass-median-diameter in particle-size distribution measurements, considered to be the average particle size by mass D50 (film) , working title for a Tamil-language film D50 (radiotherapy) , the half maximal inhibitory dose, representing the dose of light or ionising radiation that is required for 50% inactivation of a tumor cell population
The ED50 is commonly used as a measure of the reasonable expectancy of a drug effect, but does not necessarily represent the dose that a clinician might use. This depends on the need for the effect, and also the toxicity. The toxicity and even the lethality of a drug can be quantified by the TD 50 and LD 50 respectively. Ideally, the effective ...
The material safety data sheets for toxic substances frequently use this form of the term even if the substance does follow Haber's law. For disease-causing organisms, there is also a measure known as the median infective dose and dosage.
The main discussion of these abbreviations in the context of drug prescriptions and other medical prescriptions is at List of abbreviations used in medical prescriptions. Some of these abbreviations are best not used, as marked and explained here.

In toxicology, the lethal dose (LD) is an indication of the lethal toxicity of a given substance or type of radiation.Because resistance varies from one individual to another, the "lethal dose" represents a dose (usually recorded as dose per kilogram of subject body weight) at which a given percentage of subjects will die.
