In veterinary medicine a bolus is a large time-release tablet that stays in the rumen of cattle, goats, and sheep. It can also refer to a dose of liquid injected subcutaneously with a hypodermic needle, such as saline solution administered either to counteract dehydration or especially to mitigate kidney failure, a common ailment in domestic cats.
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
Model-Informed Precision Dosing (MIPD for short) is the use of pharmacometric models with computer software to optimize drug dosage for an individual patient. [1]Developed in the late 1960s under the impetus of clinical pharmacologists such as Lewis Sheiner and Roger Jelliffe, these approaches involve applying the equations and parameters describing a drug's pharmacokinetics and ...
Bolus (medicine), the administration of a drug, medication or other substance in the form of a single, large dose Bolus (radiation therapy) , a tissue equivalent substance used in radiation therapy Bolus tracking , technique used in computed tomography imaging, to visualise vessels more clearly
The solution of this differential equation is useful in calculating the concentration after the administration of a single dose of drug via IV bolus injection: = C t is concentration after time t; C 0 is the initial concentration (t=0) K is the elimination rate constant
A bolus intravenous dose of 10 or 20 mg of furosemide can be administered and then followed by intravenous bolus of 2 or 3% hypertonic saline to increase the serum sodium level. [12] Pulmonary edema - Slow intravenous bolus dose of 40 to 80 mg furosemide at 4 mg per minute is indicated for patients with fluid overload and pulmonary edema. Such ...
In conventional chemotherapy, a dose close to the maximum tolerated dose is administered in a bolus manner to achieve cytotoxic effects on tumor cells. [5] However, the side effects are often significant as the cytotoxic agents also kill the fast-dividing cells normally present in the body, such as bone marrow cells and epithelial cells of the gastrointestinal tract. [6]
Absolute bioavailability refers to the bioavailability of a drug when administered via an extravascular dosage form (i.e. oral tablet, suppository, subcutaneous, etc.) compared with the bioavailability of the same drug administered intravenously (IV). This is done by comparing the AUC of the non-intravenous dosage form with the AUC for the drug ...
