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
