Study Notes

Definition

A peptic ulcer is a sore on the lining of the stomach or duodenum (first part of the small intestine)
Caused by damage to the mucosal lining, leading to inflammation and ulceration

Types of Peptic Ulcers

Gastric ulcer: occurs in the stomach
Duodenal ulcer: occurs in the duodenum (first part of the small intestine)

Causes

Helicobacter pylori (H. pylori) infection: a type of bacteria that can cause stomach inflammation and ulcers
Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs): such as aspirin, ibuprofen, and naproxen
Zollinger-Ellison syndrome: a rare condition that causes the stomach to produce too much acid
Stress: physical or emotional stress can contribute to the development of peptic ulcers

Symptoms

Abdominal pain: usually in the upper middle part of the abdomen, and can be worse at night
Nausea and vomiting
Loss of appetite
Weight loss
Bleeding: vomiting blood or black tarry stools

Diagnosis

Endoscopy: a flexible tube with a camera is used to examine the inside of the stomach and duodenum
Upper GI series: a type of X-ray that uses a contrast agent to visualize the stomach and duodenum
Blood tests: to check for H. pylori infection

Treatment

Antibiotics: to treat H. pylori infection
Acid-reducing medications: to reduce acid production in the stomach
Antacids: to neutralize stomach acid
Proton pump inhibitors (PPIs): to block the production of stomach acid
** Lifestyle changes**: avoiding NSAIDs, managing stress, and avoiding spicy or fatty foods

Cough Medicine

Cough Suppressants

Block the cough reflex to relieve coughing
Examples: dextromethorphan, codeine
Used for dry, non-productive coughs, causing side effects like drowsiness, dizziness, and stomach upset

Expectorants

Loosen and thin mucus in the airways, making it easier to cough up
Examples: guaifenesin, acetylcysteine
Used to relieve congestion, making cough more productive, with side effects like stomach upset, diarrhea, and headache

Bronchodilators

Relax airway muscles, opening up airways
Examples: albuterol, ipratropium
Used to relieve wheezing, shortness of breath, and coughing, causing side effects like nervousness, tremors, and rapid heartbeat

Mucolytics

Break down mucus, making it easier to cough up
Examples: acetylcysteine, dornase alfa
Used to relieve thick, sticky mucus in conditions like cystic fibrosis, causing side effects like stomach upset, diarrhea, and allergic reactions

Anxiolytics

Used to treat anxiety disorders such as generalized anxiety disorder, panic disorder, and social anxiety disorder
Enhance the activity of the neurotransmitter GABA, which has a calming effect on the brain
Examples include benzodiazepines (alprazolam, diazepam, clonazepam) and non-benzodiazepines (buspirone, zolpidem)

Antipsychotics

Used to treat psychotic disorders such as schizophrenia, bipolar disorder, and schizoaffective disorder
Block the action of dopamine and other neurotransmitters in the brain
Typical antipsychotics include haloperidol and chlorpromazine
Atypical antipsychotics include olanzapine, risperidone, and quetiapine
Side effects include extrapyramidal symptoms (tremors, rigidity, dystonia) and metabolic changes (weight gain, hyperglycemia, dyslipidemia)

Antiemetics

Used to treat nausea and vomiting associated with chemotherapy, surgery, or motion sickness
Act on the brain's vomiting center, blocking the release of serotonin and other neurotransmitters
Examples include dopamine antagonists (metoclopramide, domperidone), serotonin antagonists (ondansetron, granisetron), and NK1 receptor antagonists (aprepitant)

Antiarrhythmics

Used to treat abnormal heart rhythms such as atrial fibrillation, ventricular tachycardia, and ventricular fibrillation
Affect the heart's electrical conduction system, slowing or regulating the heart rate
Classes include Class I (sodium channel blockers: quinidine, procainamide), Class II (beta blockers: propranolol, esmolol), Class III (potassium channel blockers: amiodarone, sotalol), and Class IV (calcium channel blockers: verapamil, diltiazem)

Vasodilators

Used to treat conditions such as hypertension, heart failure, and peripheral artery disease
Relax smooth muscle in blood vessels, reducing blood pressure and improving perfusion
Examples include calcium channel blockers (nifedipine, amlodipine), ACE inhibitors (enalapril, lisinopril), nitrovasodilators (nitroglycerin, isosorbide mononitrate), and alpha-adrenergic blockers (prazosin, doxazosin)
