Yes, but it is more common when using more than one Serotonergic medication

43
Q

A

Anticholinergic side effects

44
Q

The TCAs amoxapine and maprotilene are known to cause what specific side effect?

A

Seizures

45
Q

Patients run the risk of what specific side effect if tricyclic antidepressants elevate to supratherapeutic levels in the blood?

A

Cardiac abnormalities

46
Q

What may happen if a monoamine oxidase inhibitor is used in combination with a sympathomimetic medication and/or tyramine-containing foods and beverages?

A

Hypertensive crisis

47
Q

What may be the outcome if bupropion is used at higher doses or is rapidly titrated?

A

Seizure

48
Q

What could the use of bupropion in combination with such medications as antipsychotics, stimulants, and hypoglycemic drugs lead to? Why?

A

Seizures; because these are drugs that lower the seizure threshold

49
Q

Duloxetine (Cymbalta) and nefazodone (Serzone) are potentially toxic to which organ? They should be avoided in patients with what type of dysfunction?

A

Hepatotoxicity; hepatic dysfunction

Q

Effexor

A

Venlafaxine (Effexor), paroxetine (Paxil) and duloxetine (Cymbalta) are associated with a withdrawal syndrome for what pharmacological reason? What three instances increase the likelihood of a withdrawal syndrome?

A

Studies have found that the agents are similar in efficacy

63
Q

What are the major determining factors for selecting a specific antidepressant?

A

Tolerability, personal or family history of response, and cost

64
Q

Why are the “newer” antidepressant agents considered the first-line of therapy? Which two categories of antidepressants are excluded from being first-line therapy for these reasons?

A

Because they are safer (including in overdose) and easier to tolerate.

These findings were recently identified in the study “paroxetine versus other antidepressant agents for depression” by purgato et al (2014)

65
Q

What did the STAR*D study conclude regarding antidepressant therapy?

A

They concluded that when evaluating the efficacy of a therapeutic regimen:
1 – maximize the antidepressant dose
2 – ensuring adequate trial duration

Q

True or false: the STAR*D study used a “real world” design to evaluate patients with at least 1-3 previous trials

A

True

67
Q

Is electroconvulsive therapy safe in pregnancy?

A

Yes, it has no known teratogenic effects and may be preferred to antidepressant pharmacological therapy in some cases

68
Q

All antidepressant agents are categorized as category C, with regard to pregnancy, except which one?

A

Paroxetine (Paxil)

Category D

69
Q

True or false: most studies have not identified an increase in congenital malformations associated with antidepressant exposure

A

True

70
Q

The risk of cardiovascular and other congenital malformations may be higher with which antidepressant?

A

Paroxetine (Paxil)

71
Q

SSRI exposure late in the third trimester may lead to what non-teratogenic side effects in the newborn?

A

Respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, low birth weight, vomiting, hypoglycemia, hypo or hypertonia, hyperreflexia, jitteriness, irritability, constant crying, lower Apgar scores and tremor.

72
Q

The effects of antidepressants during the third trimester may be due to toxic effects of the SSRI or drug withdrawal due to discontinuation. Therefore, what technique should be used? And for how long prior to delivery?

A

Consider tapering or discontinuing antidepressant medication 10-14 days prior to delivery

73
Q

What do we know about the long-term effects of in utero SSRI exposure on infant development and behavior?

A

Nothing

74
Q

Do psychotropic agents cross into the breastmilk?

A
