Antihypertensive and Cardiac Drugs
Clonidine (Catapres)
Type: Adrenergic agonist
Action: Reduces blood pressure through central nervous system mechanisms, decreasing sympathetic outflow.
Indications:
Hypertension
Opioid or alcohol withdrawal symptoms
Dysmenorrhea (menstrual cramps)
Menopausal hot flashes
Severe pain management, especially in cancer patients.
Adverse Effects: Dry mouth, sedation, dizziness, constipation, rebound hypertension if discontinued abruptly.
Amlodipine besylate (Norvasc)
Type: Calcium Channel Blocker
Action:
Decreases the afterload on the heart, which reduces workload and myocardial oxygen demand.
Causes smooth muscle relaxation (vasodilation), which leads to increased blood flow to ischemic areas of the heart, enhancing oxygen supply.
Indications:
Angina (used as antianginal)
Hypertension
Supraventricular tachycardia (Class IV Antidysrhythmic)
Other conditions such as atrial fibrillation, flutter, migraine headaches, Raynaud’s disease, coronary artery spasm, and peripheral artery disease.
Adverse Effects: Edema, dizziness, palpitations, flushing, and fatigue.
Losartan (Cozaar)
Type: Angiotensin II Receptor Blockers (ARB)
Action:
Selectively blocks the binding of angiotensin II to its receptors, leading to vasodilation, reduced secretion of vasopressin and aldosterone, and lower blood pressure.
Indications:
Hypertension
Adjunctive therapy for heart failure
Reduces risk of stroke in patients with hypertension and left ventricular hypertrophy.
Adverse Effects: Hypotension, dizziness, hyperkalemia, and renal dysfunction.
Hydralazine (Apresoline)
Type: Vasodilator
Action:
Acts as a direct vasodilator of arterioles, which reduces systemic vascular resistance.
Indications:
Severe hypertension, including hypertensive emergencies
Heart failure as adjunctive therapy.
Adverse Effects: Reflex tachycardia, palpitations, headache, nausea, and possible lupus-like syndrome.
Diuretics and Antianginals
Diuretics
Action: Accelerates urine formation by promoting the expulsion of sodium and water through the kidneys.
Types:
Carbonic Anhydrase Inhibitor:
Example: Acetazolamide
Indications: Glaucoma, edema, high altitude sickness
Adverse Effects: Metabolic acidosis, hypokalemia, drowsiness.
Loop Potassium-Wasting:
Example: Furosemide (Lasix)
Indications: Edema from heart failure, liver or renal disease
Adverse Effects: Electrolyte imbalances (hypokalemia, hyponatremia), dehydration, hypotension, tinnitus.
Aldosterone-Inhibiting/Potassium-Sparing:
Example: Spironolactone (Aldactone)
Indications: Hypertension, hyperaldosteronism, adjunctive treatment for heart failure
Adverse Effects: Hyperkalemia, gynecomastia, menstrual irregularities.
Thiazide:
Example: Hydrochlorothiazide (Hydrodiuril)
Indications: Hypertension, diabetes insipidus, adjunct for heart failure
Adverse Effects: Electrolyte imbalances, dehydration, hyperuricemia.
Antianginal
Nitroglycerin (Nitrostat/Nitro-Bid/Nitrol)
Type: Nitrates/Nitrites
Action: A potent vasodilator that increases blood flow to the ischemic myocardium by relaxing smooth muscle in blood vessel walls.
Indications: Angina pectoris episodes, both acute and preventive.
Adverse Effects: Headache, dizziness, hypotension, reflex tachycardia, flushing.
Antidysrhythmic
Atenolol (Tenormin)
Type: Class II Antidysrhythmic (Beta-blocker)
Action: Blocks the adrenergic effects of adrenaline and noradrenaline, slowing heart rate and reducing blood pressure.
Indications: Hypertension, myocardial infarction, angina, and certain types of tachycardia.
Adverse Effects: Bradycardia, fatigue, hypotension, dizziness, and depression.
Amiodarone (Cordarone, Pacerone)
Type: Class III Antidysrhythmic
Action: Blocks potassium channels, affecting duration of action potentials and refractory periods in the cardiac cycle, correcting abnormal heart rhythms.
Indications: Supraventricular and ventricular dysrhythmias, including ventricular tachycardia and fibrillation.
Adverse Effects: Hypotension, bradycardia, pulmonary toxicity, liver, and thyroid dysfunction.
Anti-infectives
Trimethoprim/Sulfmethoxazole (TMP-SMX) (Bactrim)
Type: Sulfonamide
Action: Inhibits bacterial folic acid synthesis, which is essential for DNA and RNA synthesis in bacteria.
Indications: Treatment of urinary tract infections, infections caused by E. coli, Klebsiella, Staphylococcus aureus, Proteus mirabilis, and Proteus vulgaris.
Adverse Effects: Nausea, vomiting, rash, hyperkalemia, and Stevens-Johnson syndrome.
Amoxicillin/Clavulanate (Augmentin)
Type: Penicillin
Action: Disrupts bacterial cell wall synthesis, primarily effective against gram-positive bacteria, with clavulanate providing resistance to beta-lactamase enzymes.
Indications: Pneumonia, urinary tract infections, rhinosinusitis, otitis media, skin and soft tissue infections.
Adverse Effects: Diarrhea, nausea, allergic reactions such as rashes, and liver enzyme elevations.
Cefuroxime (Ceftin, Zinacef)
Type: Cephalosporin
Action: Similar mechanism to penicillin, effective against a broad spectrum of bacteria including gram-negative organisms.
Indications: Urinary tract infections, septicemia, meningitis, gonorrheal infections, bone and joint infections.
Adverse Effects: Gastrointestinal upset, allergic reactions, and potential for antibiotic-associated diarrhea.
Erythromycin (Erythocin)
Type: Macrolides
Action: Inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit.
Indications: Effective against a variety of respiratory and skin infections, sexually transmitted diseases, and conditions like diabetic gastroparesis and H. pylori.
Adverse Effects: Gastrointestinal upset, cholestatic jaundice, arrhythmias (with high doses).
Ciprofloxacin (Cipro)
Type: Quinolones/Fluoroquinolones
Action: Disrupts bacterial DNA replication, effective against a wide range of gram-negative microorganisms.
Indications: Urinary tract infections, pneumonia, sexually transmitted diseases, and other infections including anthrax.
Adverse Effects: Nausea, diarrhea, dizziness, increased risk of tendon rupture, particularly in older adults.
Additional Antimicrobials
Gentamicin (Garamycin)
Type: Aminoglycosides
Action: Binds to the 30S ribosomal subunit, preventing protein synthesis in bacteria.
