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.
Prandial insulin, also called mealtime or bolus insulin, is designed as a bolus dose of insulin prior to a meal to regulate the spike in blood glucose that occurs following a meal. The dose of prandial insulin may be static, or may be calculated by the patient using either their current blood sugar, planned carbohydrate intake, or both.
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 ...
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.
Nesiritide is only administered intravenously, usually by bolus, followed by IV infusion. For most adults and the elderly, a normal dosage is 2 mg/kg followed by a continuous IV infusion of 0.01 mg/kg/min. This may be increased every three hours for a maximum of 0.03 mg/kg/min.
So, the maintenance dose of foosporin is 100 milligrams (100 mg) per day—just enough to offset the amount cleared. Suppose a patient just started taking 100 mg of foosporin every day. On the first day, they'd have 100 mg in their system; their body would clear 10 mg, leaving 90 mg.
Onset of action is 1 to 2 hours after oral dosage, and 3 to 5 minutes after intravenous bolus dosage. [6] [7] Biphasic or triphasic following IV administration; terminal elimination half-life is 2–8 hours. [39] Plasma half-life of 2–8 or 4.5–12 hours after single oral dose or multiple oral doses, respectively.
where De is the effective dose, B bioavailability and Da the administered dose. Therefore, if a drug has a bioavailability of 0.8 (or 80%) and it is administered in a dose of 100 mg, the equation will demonstrate the following: De = 0.8 × 100 mg = 80 mg
