In veterinary medicine a bolus is a large time-release tablet that stays in the rumen of cattle, goats, and sheep.

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 .
When using bolus to compensate for missing tissue, the whole of the bolussed area must be level with the point on the patient where the f.s.d. is set, to ensure dose homogeneity. When the bolus is used to reduce the skin-sparing effect, the bolus does not necessarily need to touch the skin all over the bolussed area as the scatter is of ...
Bolus insulin is produced during the digestion of meals. Insulin levels rise immediately as we begin to eat, remaining higher than the basal rate for 1 to 4 hours. This meal-associated ( prandial ) insulin production is roughly proportional to the amount of carbohydrate in the meal.

When you buy a bottle of vitamins from a nutrition store, you’ll probably notice a best-by date on the bottom of the jar. But that inscribed number isn’t a hard-and-fast rule—there is some ...
The extended bolus is also useful for those with slow digestion (such as with gastroparesis or coeliac disease). A combination bolus/multiwave bolus is the combination of a standard bolus spike with an extended bolus square wave. This shape provides a large dose of insulin up front, and then also extends the tail of the insulin action.
