Antihypertensive Drugs 2 Flashcards
Direct renin inhibitors
Aliskiren
Alpha 1 blockers
Prazosin and doxasosin
Combined alpha and beta blockers
Labetalol
Centrally acting drugs
Alpha 2 adrenoceptor agonists
Alpha adrenoceptor agonists ( clonidine and alpha methyldopa)
Vasodilators
Hydralazine
Endothelin blockers
Bosentan
Dopamine agonists
Fenoldopam
From its side effects it is induce lupus erythematosus
Hydralazine
Significant baroreceptors homeostatic responses so must be combined with diuretics and beta blockers
Hydralazine and minoxidil
Drug that is k channel opener that hyperpolarizes and relaxes vascular smooth muscle
Minoxidil
Now it is used to prevent hair loss
Minoxidil
From its side effects is hirsutism (hypertrichosis)
Minoxidil
Drug that is orally active nonselective blocker of ETA and ETB receptors
Bosentan
It is selective ETA blocker
Ambrisentan
Drugs used in pregnancy
Labetalol
Alpha methyldopa
Hydralazine
Drugs used in hypertension emergencies
Labetalol
Na nitroprusside
Fenoldopam
Used in hypertension with benign prostatic hyperplasia
Prazosin
From its characteristics is there is no reflex tachycardia
Labetalol
It’s major limitation is that it has long half life
Labetalol
From its side effects
Nightmares and mental depression
Alpha methyldopa
From its side effects
Mild hyperprolactenemia and extrapyrimidal manifestation
Alpha methyldopa
From its side effects
Positive coombs test
Auto immune hemolytic anemia
Auto immune hepatitis
Alpha methyldopa
Used in hypertension complicated by renal disease
Clonidine
Used in reducing anxiety accompanying opiate withdrawal or surgical operations
Clonidine
Sudden withdrawal of the drug can lead to rebound hypertension
Clonidine
Cause salt and water retention so it is usually combined with diuretics
Clonidine
Cause sedation and dry mouth
Clonidine
Is a thiazide drugs but has no diuretics effects
Diazoxide
Used in acute HF and it is sensitive to light
Na nitroprusside
It is the main subtype in smooth muscle
ETA
Used in treatment of primary pulmonary hypertension
Bosentan and ambrisentan
It release nitric oxide from endothelial cells
Hydralazine
It is a direct aretriodilator by opening k channel
Diazoxide
It liberates nitric oxide
Na nitroprusside
Given in emergency hypertension and acute heart failure
Na nitroprusside
Toxicity of na nitroprusside can be reduced by
Sodium thiosulfate or hydroxylamine vit b 12
Stimulate peripheral dopamine D1 receptors in renal and mesenteric arteries
Fenoldopam
Used as rapid acting vasodilators to treat emergency hypertension
Fenoldopam
In patients with pulmonary hypertension and Coronary artery disease which of the following is elevated
Endothelin -1
Drug used in treatment of pulmonary hypertension
Bosentan and ambrisentan
It inhibits renin activity and RAAS
Aliskiren
Treatment of hyperreninemic hypertension
Aliskiren
Alpha one blockers
Prazosin
Block post synaptic alpha 1 adrenergic receptors leading to arterial and venous vasodilation
Prazoy
From its side effects is orthostatic hypotension more with first dose
Prazosin
Night mares
Sedation
Mental depression
Mild hyperprolactinemia
Positive coombs test are symptoms of which drug
Alpha methyldopa
Is a central alpha 2 agonist
Clonidine
