Q

How can we prevent discontinuation syndrome?

We usually wean the drug dose gradually over a period of four weeks.

However, this period is prolonged in individuals who have been taking antidepressants for longer

We can also consider switching patients to one 20mg fluoxetine per day

Q

How do lithium salts work?

88
Q

List three anticonvulsant examples

A

Sodium valproate

Carbamazepine

Lamotrigine

89
Q

How do anticonvulsants work?

A

They work by increasing GABA levels, which is an inhibitory transmitter that also plays a role in modulating glutamate and dopamine

In bipolar disorder, individua’s have diminished GABA neurotransmission. Thus, low GABA levels can result in excitatory toxicity

90
Q

When do we prescribe sodium valproate?

A

It is recommended in individuals who suffer from several manic/depressive episodes a year

It is recommended in individuals who suffer from comorbid alcohol/substance use

91
Q

How do we administer and monitor sodium valporate?

A

An initial dose of sodium valproate (500mg daily) is administered, which after 4-5 days is reviewed

The dose is gradually titrated up until a stable therapeutic level of 50– 125 is achieved, after which annual blood checks are conducted

92
Q

What are the four contraindications of sodium valproate?

A

Acute Porphyria

Severe Hepatic Impairment

Urea Abnormalities

Mitochondrial Disorders

93
Q

What are the three unique side effects of sodium valproate - apart from GI upset?

A

Weight Gain

Tremors

Hair Loss

94
Q

How do we administer and monitor carbamazepine?

A

An initial dose of carbamazepine (100mg-200mg, 1-2 times daily) is administered, which after 5 days is reviewed

The dose is gradually titrated up until a stable therapeutic level of 4– 12 is achieved, after which monthly blood checks are conducted

95
Q

What are the three contraindications of carbamazepine?

A

Acute Porphyria

AV Conduction Abnormalities

Bone Marrow Depression

96
Q

What are the three unique side effects of carbamazepine - apart from GI upset?

A

Weight Gain

Rash

Fluid Imbalance

97
Q

How do we administer and monitor lamotrigine?

A

An initial dose of lamotrigine (25mg daily on alternate days) is administered. The dose is gradually titrated up to 50mg daily after two weeks, and then 100mg daily after a further two weeks

In cases where patients experience compliance issues and stop administrating lamotrigine for 5 days, it is recommended that they start back at the initial dose

98
Q

What are the three contraindications of lamotrigine?

A

Myoclonic Seizures

Parkinson’s Disease

Brugada Syndrome

99
Q

What are the two unique side effects of lamotrigine - apart from GI upset?

A

Rash

Irritability

100
Q

It is normal for individuals on anticonvulsants to experience deranged LFTS. When should we raise concerns?

A

If LFTs are increased three times greater than the baseline

101
Q

When are anti-psychotics prescribed?

A

They are indicated in the management of psychotic disorders, including schizophrenia, bipolar disorder and psychotic depression

102
Q

What two medications are antipsychotics commonly administered in conjunction with?

A

Lithium

Sodium valproate

103
Q

How do antipsychotics work?

A

They work by inhibiting dopaminergic neurotransmission via four dopaminergic pathways

104
Q

What are the four dopaminergic pathways?

A

Mesocortical Pathway

Mesolimbic Pathway

Nigrostriatal Pathway

Tuberoinfundibular Pathway

105
Q

Where does the mesocortical pathway extend?

A

It connects the ventral tegmentum to the prefrontal cortex

106
Q

What is the function of the mesocortical pathway?

A

It is thought to be involved in cognitive control, motivation and emotional response

107
Q

What abnormalities in the mesocortical pathway results in psychotic disorders?

A

There are reduced levels of dopamine

108
Q

What psychotic clinical features arise as a result of mesocortical pathway abnormalities?

A

Negative clinical features, such as anergia, anhedonia, lack of motivation, etc

109
Q

Where does the mesolimbic pathway extend?

A

It connects the ventral tegmentum to the ventral striatum in the forebrain

110
Q

What is the function of the mesolimbic pathway?

A

It is involved in reinforcement and reward-related motor function learning

111
Q

What is another term of mesolimbic pathway?

A

Reward pathway

112
Q

What abnormalities in the mesolimbic pathway results in psychotic disorders?

A

There are increased levels of dopamine

113
Q

What psychotic clinical features arise as a result of mesolimbic pathway abnormalities?

A

Positive clinical features, such as hallucinations, delusions and thought disorders

114
Q

Where does the nigrostriatal pathway extend?

A

It connects the substantia nigra in the midbrain to the basal ganglia in the forebrain

115
Q

What is the function of the nigrostriatal pathway?

A

It is thought to be involved in movement regulation, by suppressing acetylcholine activity

Q

Where does the tuberoinfundibular pathway extend?

A

It connects the infundibular nucleus in the hypothalamus to the anterior pituitary gland
