More thanMore than 50 % 50 % of patients with depressive disorders of patients with depressive disorders don’t realize that they have any psychological problems don’t realize that they have any psychological problems

and complain only on certain somatic dischargesand complain only on certain somatic discharges

Most frequent complaints of patients with Most frequent complaints of patients with depression:depression:

Feeling of hopelessness, indifference, fear, panic attacks,tiredness, weakness, headache, dizziness, dream

disorders, dyspepsia, unpleasant feelings and pain in different parts of the body

Depressive conditions “mask” as vegetal-vascular, neuro-circulative dystonia (various vegetative

disorders), gastro-intestinal pathology, pathology of cardio-vascular, respiratory systems, manifest as dyskinesia, functional motor disorders, insomnia,

Blockers of neuronalBlockers of neuronal reuptake reuptake of serotonin of serotonin

Modern point of view on mechanism of development of depression

Primary deficiency of serotonin in synaptic cleft

Compensatory growing of quantity and sensitivity of postsynaptic 5-НТ2 receptors

Compensatory decreasing of quantity and sensitivity of presynaptic 5-НТ1 receptors in hippocampus and

nuclei row (these structures play an important role іn development of depression)

Principles of antidepressants usagePrinciples of antidepressants usage

• Endogen depression – the deeper it is, the larger doses, rate of their increasing and duration of treatment should be administered

• Step-by-step dose increasing till obtaining of effect, administration of effective dose during 4-6 weeks – 3-6 months, gradual decreasing of dose (during 5-6 weeks)

• Effect can appear only after 7-14 days after beginning of therapy (this fact should be taken into consideration in patients with suicidal dispositions)

• In case of rapid abolishing withdrawal syndrome may develop

Side effects of antidepressantsSide effects of antidepressants

• ММ-cholinoblocking action-cholinoblocking action: dry mouth, increasing of intraocular pressure, disturbance of accommodation, constipation, ischuria (important in a case of adenoma of prostatic gland!), tremor, hallucinations, disorders of consciousness, excitation

• Alpha-adrenoblocking, papaverine-like effectAlpha-adrenoblocking, papaverine-like effect: acute hypotension, orthostatic collapse (especially in combination of amitriptiline with clopheline), for correction of which adrenomimetics cannot be used (it is necessary to increase volume of circulating blood, put the legs up)

Side effects of antidepressantsSide effects of antidepressants

• Acute attacks of epilepsy epilepsy

• CardiotoxicCardiotoxic action (sudden death), three- cyclic antidepressants increase arrhythmogenic activity of drugs for general anesthesia, antihistamines etc.

• Combination of three-cyclic antidepressants Combination of three-cyclic antidepressants with IMAO is absolutely contraindicatedwith IMAO is absolutely contraindicated:: danger of development of hypertensive crisis, seizures, rapid excitation, tachycardia, cardiac arrhythmias, increasing of temperature

Rules of transferring from one kind of Rules of transferring from one kind of antidepressants to anotherantidepressants to another

• From three-cyclic to IMAO – break time– 2-3 days

• From IMAO to three-cyclic – break time – not less than 2 weeks

It is absolutely contraindicated to It is absolutely contraindicated to administer adreno(sympato)mimetics in administer adreno(sympato)mimetics in case of treatment with antidepressantscase of treatment with antidepressants

Even small doses of adrenomimetic Even small doses of adrenomimetic (sympatomimetic(sympatomimetic) ) substances in such substances in such patient can cause patient can cause hypertensive crisis:hypertensive crisis:

Mechanism of action

• Binds to adenosine adenosine (“(“purinepurine”) ”) receptorsreceptors in brain (endogen ligand of these receptors – adenosine decreases processes of excitation in CNS)

• Inhibiting of phosphodiesteraseInhibiting of phosphodiesterase, which leads to accumulation of cAMP and stimulation of many physiological processes and metabolism
