Final Review Flashcards
What are the actions of dopamine?
Asked directly and by the release of north and Effron from the sympathetic nerve terminals mediates dilation of vessels in the renal beds to maintain renal perfusion
What are some adverse affects of dopamine?
Tachycardia ectopic beats hypertension vomiting headache
What kind of drug is isoproterenol and what are its indications?
Beta specific adrenergic agonist
Management of bronchospasm during anesthesia serious Ventricular arrhythmias that require increased inotropic action, vasopressor during shock
What are the actions of isoproterenol?
Acts on beta adrenergic receptors to produce increased heart rate, positive inotropic effect, bronchodilation chroma and vasodilation
What kind of drug is atropine and what are its indications?
Anticholinergic
To decrease secretions before surgery, treatment of parkinsonism, restoration of cardiac rate and arterial pressure following vagal stimulation,
What are the actions of atropine?
Competitively blocks acetylcholine muscarinic receptors sites blocking the effects of parasympathetic nervous system
What are the indications of beractant?
Prophylactic treatment of infants at high risk for developing respiratory distress syndrome; RDS
Rescue treatment of infants who have developed RDS
What are the actions of beractant?
Natural bovine compound of lipoprotein’s that reduce the surface tension and expansion of the alveoli ; replaces surfactant that is missing in infants with RDS
Diphenhydramine
Indications: symptomatic relief of Perenial and seasonal rhinitis used for motion sickness and parkinsonism as a night time sleep aid
Actions: competitively blocks that effects of histamine at H-1 receptor sites; has atropine like antipruritic and sedative effects
What kind of drug is dextromethorphan and what are its indications?
Anti-tussive
Control of nonproductive cough.
Actions: depresses the cough center in the medulla to control cough spasms
Epinephrine
Indications: treatment of anaphylactic reactions, acute asthmatic attacks; relief of respiratory distress from chronic obstructive pulmonary disease in bronchial asthma
Actions: reacts at alpha and beta receptors sites in the sympathetic nervous system to cause bronchodilation increased heart rate increased respiratory rate and increased blood pressure
Furosemide (Lasix)
Loop Diuretic
Indications: treatment of edema associated with heart failure, acute pulmonary edema, hypertension.
Actions: inhibits to be absorption of sodium and chloride in the distal Renal tubules in the loop of Henley, leading to a sodium rich diuresis.
Phenazopyridine
Urinary tract analgesic
Indications: symptomatic relief of pain, urgency, burning, frequency, and discomfort related to lower urinary tract irritation caused by infection, trauma, surgery, or various procedures
Actions: has a direct, topical analgesic effect on the urinary tract mucosa; mechanism of action is not known
Adverse affects: yellowish tinge to skin sclera urine
Difference between UTI & Pylenophritis
UTI: urinary frequency, urgency, burning on urination.
Pylenophritis:
Chills, fever, flank pain, tenderness
What kind of drug is dopamine and what are its indications?
Dopamine is a alpha and beta adrenergic antagonist and it is for a correction of hemodynamic imbalances present in shock
