Used for hypertension and ADHD
Which drug class does Dobutamine belong to?
Beta-1 adrenergic agonist
Used in heart failure and cardiogenic shock
What receptors does Dopamine stimulate?
Dopamine, beta-1, and alpha-1 receptors
Used in shock and heart failure
What is the primary use of Epinephrine (Epi)?
Used in anaphylaxis, cardiac arrest, and asthma
Stimulates alpha and beta adrenergic receptors
Is Isoproterenol a selective or non-selective beta adrenergic agonist?
Non-selective beta adrenergic agonist
Used in bradycardia and heart block
What is the mechanism of action of Norepinephrine (Norepi)?
Stimulates alpha-1, alpha-2, and beta-1 adrenergic receptors
Used in shock and hypotension
What is the drug class of Amphetamine?
CNS stimulant
Used for ADHD and narcolepsy

Acetylcholinesterase inhibitor
Used in the diagnosis of myasthenia gravis
What is the mechanism of action of Organophosphate?
Irreversibly inhibits acetylcholinesterase, increasing acetylcholine levels
Used as insecticides and nerve agents
What type of drug is Atropine?
Anticholinergic
Used in bradycardia and as an antidote for organophosphate poisoning
What is the drug class of Sildenafil?
Phosphodiesterase-5 (PDE5) inhibitor
Used to treat erectile dysfunction and pulmonary arterial hypertension
What is the mechanism of action of Dihydropyridines?
Inhibit L-type calcium channels, reducing calcium influx into vascular smooth muscle cells
Used to treat hypertension and angina
What is the drug class of Verapamil?
Calcium channel blocker
Used to treat hypertension, angina, and certain arrhythmias
What is the mechanism of action of Methyldopa?
Stimulates alpha-2 adrenergic receptors in the central nervous system, reducing sympathetic outflow
Used to treat hypertension, especially in pregnancy
What is the primary use of Propranolol?
Used to treat hypertension, angina, and certain arrhythmias
Blocks beta-adrenergic receptors
What is the mechanism of action of Minoxidil?
Opens potassium channels in vascular smooth muscle cells, leading to hyperpolarization and vasodilation
Used to treat severe hypertension and promote hair growth
What type of drug is Sodium nitroprusside?
Vasodilator
Used to treat hypertensive emergencies
What is the mechanism of action of Digoxin?
Inhibits sodium-potassium ATPase, increasing intracellular calcium and enhancing cardiac contractility
Used to treat heart failure and certain arrhythmias
What is the drug class of Amiodarone?
Antiarrhythmic (Class III)
Used to treat certain arrhythmias
