Pharmacology II Flashcards
What are non rx therapies for headache?
Acetaminophen, acetaminophen/cafeine/codeine
ASA
Ibuprofen
Naproxen sodium
What are treatments for pregnancy (headache)
Ibuprofen, ASA (safe in intermittent doses during 1st and 2nd trimesters)
Acetaminophen safe during all trimesters
What are Natural products for migraines
Butterbur, coenzyme Q10, melatonin, magnesium, vitamin b2
What are causes of fever?
Infection, heat exhaustion, inflammatory conditions (rheumatoid arthritis), cancerous and medications
Medications for treating fever and how they work
Acetaminophen, ASA, ibuprofen and naproxen sodium (reduce patient discomfort)
Naproxen and ASA should not be used in children
Antipyretics (Naproxen sodium, ASA) reduce body temperature by decreasing prostaglandin synthesis in the brain and reducing the thermoregulatory set-point. They do not lower normal body temperature.
Treatment for fever in kids
Naproxen and ASA (Reye disease) should not be used
Ibuprofen
Acetaminophen
What are Antihistamine classes
Second generation (bilastine, cetirizine, desloratadine, fexofenadine, loratadine, rupatadine) , : more selective for H1 receptor and less lipophilic
Do not cross the blood-brain barrier
First generation (chlorpheniramine, diphenhydramine) : dry mouth and nasal passages, difficulty voiding urine, constipation, CNS effects (sedation, psychomotor and cognitive impairment)
Side effects of topical decongestants
oral : (Mild CNS, nervousness, excitability, restlessness, dizziness, weakness, insomnia)
Increased Blood pressure, tachycardia or palpitation
Topical: local burning and stinging, sneezing, dryness of the nasal mucosa
Rhinitis medicamentosa used more than 3-5 days
Non pharm therapy for colds
Hydration with oral liquids and humidification of room air may be beneficial
Nasal saline irrigation can help nasal congestion
Avoid inhaled irritants such as smoke, dust, pollutant and allergens
Types of decongestants
Pseudoephedrine (oral)
Phenylephrine (oral)
Oxymetazoline (topical)
Phenylephrine (Topical)
Xylometazoline (topical)
What is a antitussive and what are examples?
Act centrally to suppress cough
Inhibit motor control of cough
If used by a patient with a productive cough, more mucus is retained
Dextromethorphan and codeine
Antitussives for kids
Dextromethorphan > 12 (6-11 years old)
Honey 1-18
Codeine not good for children
What is an expectorant?
The protussive agents act peripherally
Reduce sputum viscosity. Permitting more effective removal of secretions from the respiratory tract
What is a common type of expectorant?
Guaifenesin
What are expectorant used for?
Enhance cough effectiveness by promoting the clearance of airway secretions.
Natural health products for colds
Echinacea
Garlic
Ginseng
Vitamin C
Zinc
How to prevent swimmer’s ear
Avoid cotton-tipped swabs
Avoid water sports for at least 7-10 days during treatment
Earplugs and bathing caps
Avoid overzealous cleansing and scratching
After swimming or bathing, dry the external canal with a blow dryer set on low
Dimenhydrinate vs promethazine
Promethazine has a longer duration of action as compared with dimenhydrinate and may be an alternative in patients with refractory nausea or when dimenhydrinate is ineffective
Non pharm measures for nausea and vomiting
Smaller meals
Adequate hydration
Avoid smells and foods
Dietary interventions
Relaxation therapy
Acupressure wristbands
Aromatherapy
Maintaining fluid intake
Non pharm for constipation
Increase calories if low caloric intake
Have a regular bowel regimen
Consume a high-fiber diet
Fruit/ juice: natural laxative sorbitol
Restrict dairy: cow milk-free diet may improve constipation in kids
Exercise, weight loss,biofeedback/relaxation
Symptoms of dehydration
Feeling thirsty and lightheaded
A dry mouth
Tiredness
Having dark coloured, strong-smelling urine
Passing urine less often than usual
Types of laxatives
Bulk-forming (psyllium, bran): increase stool volume and are considered for long-term use.
- Gas formation. Increased osmotic load, water retention and wall stress
Emollient: Stool softeners (docusate sodium or docusate calcium) act as surfactants to often the stool by allowing the mixing of aqueous and fatty substances.
Osmotic: increased pressure on the lumen wall induces gastric motility
(Polyethylene, glycol, lactulose)
Stimulant: Bisacodyl, senna, sodium picosulfate
- increases colonic peristalsis by producing rhythmic muscle contractions in the intestines
Special considerations for bulk forming laxatives
Given > 250 ml water/juice to prevent fecal impaction and or esophageal obstruction
Do not use in patients dehydrated,fluid restricted, opioids
Require 12-72 hours for onset of effect
Psyllium improves stool frequency and consistency
Bran reduces use of laxatives in the elderly
Signs and symptoms of constipation
Infrequent defecation
Abdominal distention
Flatulence
Nausea
Vomiting
Anorexia
Early satiety
Stools that are small, hard and or difficult to evacuate
Incomplete rectal emptying
Rectal bleeding due to fissures or hemorrhoids
Weight loss
