Other Medications Flashcards
Calcium Gluconate
(mechanism of action)
♦ Intravenous administration of calcium gluconate increases serum ionized calcium level
♦ essential for the functional integrity of the nervous, muscular, and skeletal systems
♦ plays a role in normal cardiac function, renal function, respiration, blood coagulation, and cell membrane and capillary permeability
Calcium Gluconate
(side effects)
Hypotension
Bradycardia
Arrhythmia
Cardiac Arrest
Chalky or Metallic Taste
Calcium Gluconate
(indications)
♦ Calcium Channel Blocker overdose
♦ Magnesium Sulfate drip toxicity
♦ Hypocalcemia / Hyperkalemia
Calcium Gluconate
(contraindications)
♦ Cardiac arrhythmias may occur if calcium and cardiac glycosides are administered together.
♦ Hypercalcemia increases the risk of digoxin toxicity
♦ Administration of Calcium Gluconate in Sodium Chloride Injection should be avoided in patients receiving cardiac glycosides (Digoxin / Lanoxicaps, Lanoxin, Digibind)
Calcium Gluconate
(adult dose - asystole/PEA)
Asystole / PEA
1 - 2 GM IO/IV

(adult dose - bradycardia/CCB overdose
musculoskeletal trauma)
Bradycardia / Calcium Channel Blocker Overdose/Musculoskeletal Trauma
♦ 1-2 GM Slow IVP
Calcium Gluconate
(adult dose - eclampsia / preeclampsia / preterm labor)
Eclampsia / Preeclampsia / Preterm Labor
♦ 1 gram over 2-3 minutes if Mag toxicity is suspected
Calcium Gluconate
(pediatric dose - poisioning/OD/musculoskeletal trauma)
Poisoning / Overdose / Musculoskeletal Trauma
♦ 60 mg/kg IO/IV slow administration
(max dose 2GM)
Calcium Gluconate
(pregnancy safe)
Pregnancy Class C
It is unknown if calcium gluconate can cause fetal harm when administered during pregnancy or can affect reproductive capacity.
Calcium gluconate should be given to a pregnant woman only if clearly needed.
Calcium Chloride
(mechanism of action)
♦ Calcium is the primary component of skeletal tissue
♦ The fifth most abundant element in the body
♦ Essential for the functional integrity of the nervous and muscular systems
♦ For hyperkalemia, the influx of calcium helps restore the normal gradient between threshold potential and resting membrane potential
Calcium Chloride
(side effects)
Hypotension,
bradycardia,
arrhythmia,
cardiac arrest,
chalky or metallic taste
Calcium Chloride
(indications)
Calcium Channel Blocker overdose
Magnesium Sulfate drip toxicity
Hypocalcemia / Hyperkalemia
Calcium Chloride
(contraindications)
Calcium gluconate is contraindicated in patients with hypercalcemia.
Use with extreme caution in patients taking digitalis or digitalis toxicity because of an increased risk of developing arrhythmias.
Cardiac glycosides and calcium gluconate both increase intracellular calcium, so calcium gluconate can worsen digitalis toxicity.
Calcium Chloride
(adult dose)
♦ Asystole / PEA
→ 1 GM IO/IV
♦ Bradycardia / Calcium Channel Blocker
Overdose/Musculoskeletal Trauma
→ 1 GM IV slow administration
♦ Eclampsia / Preeclampsia / Preterm Labor
→ 1 GM over 2-3 minutes if toxicity of Magnesium is suspected
Calcium Chloride
(pediatric dose)
♦ Poisoning / Overdose / Musculoskeletal Trauma
→ 20 mg/kg IO/IV slow administration
(max dose 2GM)
Calcium Chloride
(pregnancy safe)
Pregnancy Class C
It is unknown if calcium gluconate can cause fetal harm when administered during pregnancy or can affect reproductive capacity. Calcium gluconate should be given to a pregnant woman only if clearly needed.
Glucagon
(mechanism of action)
Native human glucagon is a hormone synthesized by the alpha-2 cells of the pancreatic islets of Langerhans and acts to increase blood glucose.
♦ Glucagon induces glycogenolysis to increase blood glucose. (causes liver to convert stored glycogen into glucose and release into blood stream)
♦ Also exhibits chronotrophic and inotropic effects.
Glucagon
(onset and duration)
♦ IM - The maximal glucose concentrations occur 30 minutes Blood glucose concentrations return to normal or hypoglycemic levels within 1 to 2 hours.
♦ IV - The maximal glucose concentrations occur 5 to 20 minutes Blood glucose concentrations return to normal or hypoglycemic levels within 1 to 2 hours.
Glucagon
(side effects)
Allergic reactions may occur and include generalized rash, and in some cases anaphylactic shock, and hypotension, nausea and vomiting
Glucagon
(indications)
Hypoglycemia
Beta Blocker overdose
(exhibits chronotrophic and inotropic effects)
Glucagon
(contraindications)
Insulinoma, glucagon may produce an initial increase in blood glucose; however, glucagon administration may directly or indirectly (through an initial rise in blood glucose) stimulate exaggerated insulin release from the insulinoma.
Pheochromocytoma, because the drug may stimulate the release of catecholamines from the tumor. Stimulation of catecholamine release by exogenous glucagon can cause a substantial increase in blood pressure.
Glucagon
(adult dose)
♦ Beta Blocker OD / Bradycardia
→ 1 mg IM/IO/IV/IN
♦ Diabetic Emergency
→ 1 mg IM/IN
Glucagon
(pediatric dose)
♦ Beta Blocker OD / Bradycardia
→ 0.1mg/kg IV/IO/IM/IN
(max dose 2mg)
♦ Diabetic Emergency
→ 0.1mg/kg IM/IN
(max dose 1mg)
Glucagon
(pregnancy safe)
Pregnancy Class B
limited clinical data in humans have revealed that there is very low or even negligible embryo and/or fetal risk from glucagon administered during pregnancy.
(there appears to be little risk to the nursing infant if the drug is clinically necessary for treatment of the lactating woman)
Reglan (Metoclopramide)
(mechanism of action)
♦ Metoclopramide enhances gastric motility without stimulating gastric secretions.
♦ High doses of metoclopramide depress the mechanical activity of GI smooth muscle, while low doses stimulate it.
♦ Antiemetic effects of metoclopramide are mainly the result of central dopamine antagonism and increased gastric motility
Reglan (Metoclopramide)
(onset and duration)
onset of action is 1 to 3 minutes after IV injection
Reglan (Metoclopramide)
(side effects)
Dystonic Reaction / Seizures / Hallucinations,

Methylprednisolone (Solu-Medrol)
(mechanism of action)
♦ Corticosteroids bind to the glucocorticoid receptor, inhibiting pro-inflammatory signals, and promoting anti-inflammatory signals
♦ The short term effects of corticosteroids are decreased vasodilation and permeability of capillaries, as well as decreased leukocyte migration to sites of inflammation
♦ Decreases inflammation by suppression of migration of polymorphonuclear leukocytes and reversal of increased capillary permeability

excretion is almost complete within 12 hours
Onset IM: Systemic absorption is rapid following IM administration
