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.

(dose)

46
Q

Thiamine

(mechanism of action)

A

Thiamine combines with adenosine triphosphate (ATP) in the liver, kidneys, and leukocytes to produce thiamine diphosphate.

Thiamine diphosphate acts as a coenzyme in carbohydrate metabolism, in transketolation reactions, and in the utilization of hexose in the hexose-monophosphate shunt.

Without adequate thiamine, pyruvic acid does not undergo conversion to acetyl-CoA and cannot enter the Krebs cycle. Pyruvic acid accumulates in the blood and is subsequently converted to lactic acid, with the potential development of lactic acidosis.

Diminished production of NADH in the Krebs cycle also results in lactic acid production through facilitation of anaerobic glycolysis.

Q

Famotidine (Pepcid)

(mechanism of action)

A

Famotidine competitively inhibits the binding of histamine to H2-receptors on the gastric basolateral membrane of parietal cells, reducing basal and nocturnal gastric acid secretions. The drug also decreases the gastric acid response to stimuli such as food, caffeine, insulin, betazole, or pentagastrin.

Famotidine reduces the total volume of gastric juice, thus indirectly decreasing pepsin secretion. The drug does not appear to alter gastric motility, gastric emptying, esophageal pressures, biliary secretions, or pancreatic secretions.

66
Q

Promethazine

(mechanism of action)

A

The predominant action of promethazine is antagonism of H1-receptors. Although promethazine is classified as a phenothiazine, its ability to antagonize dopamine is approximately one-tenth that of chlorpromazine.

Like other H1-antagonists, promethazine does not prevent the release of histamine, but competes with free histamine for binding at H1-receptor sites.

The relief of motion sickness and nausea/vomiting appear to be related to central anticholinergic actions and may implicate activity on the medullary chemoreceptor trigger zone.

67
Q

Promethazine

81
Q

Mannitol

(mechanism of action)

A

Intravenous mannitol exerts its osmotic diuretic effect as a solute of relatively small molecular size being largely confined to the extracellular space.

Mannitol hinders tubular reabsorption of water and enhances excretion of sodium and chloride by elevating the osmolarity of the glomerular filtrate.

The increase in extracellular osmolarity induces the movement of intracellular water to the extracellular and vascular spaces.

This action underlies the role of mannitol in in reducing intracranial pressure, intracranial edema, and intraocular pressure.

82
Q

Mannitol

(onset and duration)

A

distributes into the extracellular space within 20 to 40 minutes

Diuresis generally occurs in 1 to 3 hours

Decrease in the cerebrospinal fluid pressure will occur in approximately 15 minutes

Will persist for 3 to 8 hours after the infusion is stopped

83
Q

Mannitol

(side effects)

A

Dizziness,

Fever,

Headache, Seizures,

Angina,

Edema - with vascular congestion or pulmonary edema - manitol administration may result in hypervolemia leading to or exacerbating existing congestive heart failure

Hypotension - mannitol acutely raises plasma and extracellular osmolality, which leads to an increase in circulating blood volume. This leads to increase in stroke volume, cardiac output, and blood pressure. Following diuresis, patients may be slightly hypovolemic with associated decreases cardiac output and blood pressure.

Tachycardia,

Blurred Vision,

Dehydration - Too rapid infusion of large amounts of mannitol will cause a shift of intracellular water into the extracellular compartment resulting in cellular dehydration

Urticarial,

Chills,

Thrombophlebitis,

Fluid and electrolyte imbalance - Excessive loss of water and electrolytes may lead to serious imbalances. (hyponatremia, hypernatremia, hyperkalemia, hypokalemia; metabolic acidosis)

CHF - mannitol administration may result in hypervolemia leading to or exacerbating existing congestive heart failure. Accumulation of mannitol due to insufficient renal excretion increases the risk of hypervolemia.

89
Q

Lidocaine (Xylocaine)

(mechanism of action)

A

Lidocaine stabilizes neuronal membranes by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthetic action.

Lidocaine produces its analgesics effects through a reversible nerve conduction blockade by diminishing nerve membrane permeability to sodium, just as it affects sodium permeability in myocardial cells.

Lidocaine’s antiarrhythmic effects result from its ability to inhibit the influx of sodium through the “fast” channels of the myocardial cell membrane, thereby increasing the recovery period after repolarization. Lidocaine suppresses automaticity and decreases the effective refractory period and the action potential duration in the His-Purkinje system at concentrations that do not suppress automaticity at the SA node.

90
Q

Lidocaine (Xylocaine)

(onset and duration)
