Flashcards in CYCLOPLEGICS Deck (78)
-an enzyme of catecholamine metabolism
An enzyme of catecholamine metabolism
Paralysis of the ciliary body musculature responsible for accommodation
What is ANAPHYLAXIS
- Acute, systemic allergic hypersensitivity reaction to a previously sensitized allergen
Serious anaphylactic reactions develop within minutes (up to 2 hours) and require immediate emergency treatment with epinephrine
what are the dosage of EPIPEN ?
EpiPen Jr 0.15mg
Pregnancy category C
what diseases should you be cautious wit EPI-PEN
Caution in patients with heart disease or high blood pressure, Parkinson's disease, diabetes, or a thyroid disorder
FIGHT OR FLIGHT
Regulated by the SYMPATHETIC or ADRENERGIC branch of the autonomic nervous system
REST AND DIGEST
Regulated by the PARASYMPETHETIC or CHOLINERGIC branch of the autonomic nervous system
Nicotininc Receptors are located in the ANS HOW?
using postganglionic in the ANS and terminally located in the somatic nervous system
Muscarinic receptors are associated with?
Terminal organs of postganglionic nerves in the cholinergic system
Norepinephrine (NE) are used?
NT used in sympathetic adrenergic system and its target receptors are ALPHA AND BETA
Presynaptic FOUND IN THE SYMPATHETIC PHARMACOLOGY
+α2 inhibition of signal propagation
+α1 vasoconstriction; +β2 vasodilation
+β1 ↑ contractility & conduction
+β2 ↑ insulin release;
+α2 ↓ insulin release
+β2 relaxation & ↑ aqueous production
-β2 or +α2 ↓ aqueous production
What is Relative receptor Activity?
Epinephrine Vs Norepinephrine
when it comes to Alpha 1
Norepeinephrine (NE) - Neurogenic
it is NE> E (epinephrine)
What it comes to alpha 2
Epinephrine (greater than equal) to NE
When it comes beta 1
Epinephrine (equals) to NE
when it comes to beta 2?
What are ocular adrenergic Effects on Mydriasis?
- Increase interpalpebral aperture (Müeller’s muscle)
- Modulate aqueous generation
- Receptors in lateral rectus modulate vascular tone
- Receptors in trabeculum & Schlemm’s canal suppress accommodation
What is the standard care for all new patients when it comes do dilation?
Last to be performed in exam sequence
Bilateral under most every circumstance
What should be used to estimate the ocular angle?
Gonioscopy > Van Herick > shadow test
Commonly large in myopes and aphakes
