Study Notes

Drugs Used to Treat Disorders of the Urinary System

Ciprofloxacin (Cipro): Treats recurrent UTIs caused by E. coli, P. mirabilis, and others. Not effective against pseudomonas.
Fosfomycin: Single-dose treatment for UTIs. Mix with 90-120 mL of water.
Pyridium: Relieves burning, pain, urgency, and frequency associated with UTIs. Causes reddish-orange urine, which may stain light-colored clothing.
Tolterodine (Detrol): Blocks cholinergic receptors in the bladder, causing relaxation. Reduces urgency and frequency of bladder contractions in patients with overactive bladder.

Drugs Used to Treat Glaucoma and Other Eye Disorders

Adrenergic agents: Produce mydriasis (pupil dilation) for ocular examinations.
Beta-blocking eye agents: Reduce intraocular pressure. Mechanism unknown. Little effect on pupil size.
Eye drop administration: Apply gentle traction to lower eyelid; drop medication into lower conjunctival sac. Apply pressure to inner canthus; wait 1 to 5 minutes between drops for multiple medications.
Isopto Atropine (atropine sulfate): Used in glaucoma treatment. Caution patients on tasks requiring visual acuity.
Pilocarpine: Reverses mydriasis and cycloplegia (ciliary muscle paralysis) in patients to prevent vision damage if ophthalmic medications are used surgically.

Drugs Used to Treat Cancer

Antineoplastic drugs: Common side effects include bone marrow depression, hepatotoxicity, stomatitis, cardiotoxicity, alopecia, nausea, vomiting, and diarrhea.
Chemotherapy: More effective on rapidly dividing cells. Combines cell-cycle specific and non-specific drugs. Toxic effects differ depending on organ and time of exposure.
Filgrastim: Stimulates production of neutrophils (a type of white blood cell).

Drugs Used to Treat Musculoskeletal System

Baclofen (Lioresal): Acts differently from centrally acting agents. Used to manage muscle spasticity from various causes. Used for spinal cord injuries, cerebral palsy, and multiple sclerosis.
Colchicine (Lolgout): Prevents and relieves acute gout attacks.
Cyclobenzaprine (Flexeril): Relieves muscle spasms, often in combination with other therapies.
Dantrolene (Dantrium): Treats neuroleptic malignant syndrome (NMS)
Probenecid: Promotes renal excretion of uric acid and inhibits its reabsorption, aiding in gout treatment. Note the use of the chronic condition designation.

Antimicrobial Agents

Aminoglycosides: Associated with neuromuscular blockade (specifically, respiratory depression) and ototoxicity when used with muscle relaxants.
Antifungals and Corticosteroids: Can cause hypokalemia if given together.
Broad-spectrum antibiotics: Initial treatment before culture and sensitivity testing.
Cephalosporins: Caution for penicillin allergies.
Penicillins: Inhibit cell wall synthesis.
Culture and Sensitivity: Identifies the specific causative pathogen. For example, in determining the need to use antibiotics, cultures can distinguish the presence of fungi.
Fluconazole (Diflucan): Treats meningitis and candidiasis.
Isoniazid (INH): Treatment and prevention of tuberculosis.
Nystatin: Treats yeast infections.
Oseltamivir (Tamiflu): Reduces influenza symptoms if administered early.
Prophylactic antibiotics: For patients with heart conditions. Note the condition designation.
Adverse effects from antibiotics can affect multiple organ systems.

Herbal and Dietary Supplement Therapy

Black Cohosh: Reduces symptoms of PMS, dysmenorrhea, and menopause. This use of the herbal supplement is to manage symptoms.
Dietary supplements: Classified as food. FDA does not evaluate these types of products.
Examples include echinacea, garlic, ginger, gingko biloba, melatonin, st. john's wort.

Alcohol Withdrawal and Substance Abuse

Alcohol withdrawal can result in visual/auditory hallucinations and seizures.
Antabuse{Antabuse}Antabuse (Disulfiram): Used as a deterrent to alcohol consumption via the induction of nausea and vomiting.
Health professionals can also face burnout and substance abuse; behavioral changes indicate possible issues.
