Pharm part 1 Flashcards
Common indications for HCTZ
Adjunctive therapy in edema associated with CHF, hepatic cirrhosis, forms of renal dysfunction, or control of HTN
MOA of HCTZ
Inhibits reabsorption of sodium and chloride at the distal renal tubule
Common adverse effects of HCTZ
Dry mouth Muscle cramps Weakness Orthostasis Photosensitivity
Renal or hepatic dosage adjustments for HCTZ
CrCl <10 mL/min- use not recommended
Contraindicated with anuria
Clinically significant drug interactions: HCTZ
Decreases effect of sulfonylureas
May cause digitalis-induced arrhythmias with digoxin
Major counseling points for HCTZ
Take in the AM
Avoid excessive sunlight exposure
Store in cool, dry place away from sunlight
If dose is missed, skip it and return to normal schedule
Monitoring parameters for HCTZ
BP
Potassium
Hemodynamic status
Edema in fluid overload pts
Common indications for tramadol
Management of moderate to moderately severe pain
MOA of tramadol
Mu-opioid agonist
Inhibits reuptake of serotonin and norepinephrine
Common adverse effects of tramadol
Dizziness/vertigo
Nausea
HA
Drowsiness
Renal or hepatic dosage adjustments for tramadol
IR: CrCl <30 mL/min: 50-100 mg every 12 hrs, max 200 mg/day ER: should be avoided if CrCL <30 mL/min Cirrhosis: 50 mg every 12 hrs, should be avoided in pts with severe (Child-Pugh class C) hepatic dysfunction
Clinically significant drug interactions for tramadol
May potentiate effects of MAOIs, TCAs
Increased risk of seizure when given with SSRIs, TCAs, and opioids
Carbamazepine decreases levels of tramadol
Major counselling points for tramadol
May cause drowsiness- use caution when operating machinery/driving
Avoid alcohol while taking this medication
May take with food or milk to avoid GI upset
Do not split, crush or chew ER tabs
Take only as directed
Store in cool dry place away from kids and sunlight
If dose is missed, skip and return to nl dosing schedule
May produce psychological and physical dependence with continuous use
Could potentially lower the seizure threshold
Use with caution in pts with h/o seizures
Monitoring parameters of tramadol
Pain control
Misuse
Abuse
Common indications of Tylenol #3
Relief of mild-to-moderate pain
MOA of Tylenol #3
Acetaminophen: Believed to inhibit the synthesis of prostaglandins in the CNS and peripherally block pain impulse generation; produces antipyresis from inhibition of hypothalmic heat-regulating center
Codeine: Binds to opiate receptors in the CNS, causing inhibition of ascending pain pathways, altering the perception of and responses to pain, causes cough suppression by direct central action in the medulla; produces generalized CNS depression
