Drug choice is based on individual aspects, including concomitant disease.
SSRIs are preferred due to better tolerance and lower overdose risk.
Antidepressant effects take several weeks to appear; decisions on changes in dose or drug should not be rushed.
MAOI usage is restricted to specialists.
An effective regimen should continue for at least two years.
Specialist consideration for possible use of electroconvulsive therapy in urgent situations.
Anxiolytics (e.g., benzodiazepines) or antipsychotic drugs are useful adjuncts for some patients.

These phases can significantly impact behavior, energy levels, and daily functioning.

Treatment of Bipolar Disorder: Lithium Salts

Lithium Carbonate:
- Administered orally.
- Excreted by the kidneys.
- Narrow therapeutic margin, requiring monitoring of plasma concentration.

Depression

Maintenance phase of depression treatment depends on the evolution of the disease.
Prodepressive pathways involve the hypothalamic-pituitary-adrenal axis.
Antidepressive pathways involve NA, 5-HT, and BDNF.
Tricyclic antidepressants (TCAs) are non-selective amine reuptake inhibitors
Selective serotonin reuptake inhibitors (SSRIs) are a class of antidepressants that selectively inhibit the reuptake of serotonin in the synapse.
Monoamine oxidase inhibitors (MAOIs) inhibit the enzyme monoamine oxidase, which breaks down neurotransmitters like serotonin, norepinephrine, and dopamine.
Serotonin and Noradrenaline Uptake Inhibitors (SNRIs) are a class of antidepressants that work by inhibiting the reuptake of both serotonin and norepinephrine.

Treatment of Depression: Tricyclic Antidepressants (TCAs)

Mechanism of action: TCAs block the uptake of amines, specifically inhibiting norepinephrine and serotonin reuptake (with less effect on dopamine reuptake).
Pharmacokinetics: TCAs are highly liposoluble drugs, allowing for good distribution throughout the body, including the blood-brain barrier.
Pharmacological actions: TCAs have antidepressant, anxiolytic, sedative, and analgesic actions.
Adverse Drug Reactions (ADRs): TCAs can cause cardiovascular, antimuscarinic, neurological, and other side effects.
Drug Interactions: TCAs can enhance the actions of catecholamines and MAOIs. They can also increase the activity of oral anticoagulants (warfarin) and potentiate the effects of alcohol and anesthetic agents.

Treatment of Depression: Selective Serotonin Reuptake Inhibitors (SSRIs)

Mechanism of action: SSRIs selectively inhibit serotonin reuptake in the synaptic cleft.
Adverse Drug Reactions (ADRs): SSRIs may cause headache, insomnia, sexual dysfunction, dry mouth, dizziness, sweating, and decreased appetite.
