ORGANOTROPIC AGENTS - Hypertensive (anti-hypotensive) drugs. Drugs influencing cerebral blood flow. Anti-migraine agents Flashcards
The main principle of shock treatment is
To improve the peripheral blood flow
Drug which increases cardiac output
Noradrenalin
The synthetic vasoconstrictor having an adrenomimic effect
Phenylephrine
Indicate the vasoconstrictor of endogenous origin
Angiotensinamide
Which type of receptors can be activated by angiotensinamide
Angiotensin’s receptors
General unwanted effects of vasoconstrictors is
Decrease of peripheral blood flow
For increasing blood pressure in case of low cardiac output the following agents must be used
Positive inotropic drugs
Positive inotropic drug of glycoside structure
Digoxin
Positive inotropic drug of non-glycoside structure
Dobutamine
Dopamine at low doses influences mainly
Dopamine receptors (leads to vasodilation of renal and mesenterial vessels)
Dopamine at medium doses influences mainly
Beta-1 adrenoreceptors (leads to enhanced cardiac output)
Dopamine in high doses influences mainly the
Alfa-adrenoreceptors (leads to peripheral vasoconstriction)
Group of drugs for treatment of shock with hypovolaemia (reduced circulating blood volume)
Plasmoexpanders
Group of drugs for chronic hypotension treatment
Analeptics and tonics
Indicate the group of drugs influencing the cerebral flow
- Ca-channel blockers
- Derivatives of GABA
- Derivatives of Vinca minor plant
Grug influencing the blood flow which is related to antiplatelet agents
Aspirin
Which drugs is related to anticoagulants and may be useful in disorders of cerebral circulation?
Heparin
Indicate the drugs which are Ca-channel blockers influencing the brain blood flow
Nimodipine, Cinnarizine
Indicate the drugs influencing the blood flow in the brain - derivatives of GABA
Aminalon, Picamilon
Indicate the drug - Vinca minor alcaloid
Vinpocetine
Drug – a derivative of Ergot
Nicergoline
Indicate the nootropic agent useful in disorders of brain circulation
Pyracetam
What is the main action of GABA derivatives in disorders of brain circulation?
Stimulation of the metabolic processes in neurons
Appropriate mechanism of vinpocetine action
It dilates cerebral vessels and improves blood supply
Antiaggregants are used in disorders of brain circulation for
Improving the microcirculation in cerebral tissue
Migraine is a disorder connected with
Dysfunction of regulation of cerebral vessel tonus
True or False. Main agents for acute migraine attack treatment are Ergot and indol derivatives and NSAID’s.
TRUE
The following Indol derivative is used for treatment of acute migraine attack
Sumatriptan
The following Ergot derivative is used for treatment of acute migraine attack
Ergotamine
The derivative of lysergic acid for migraine attack prevention is
Methysergide
