Pharm 10 Adrenergics Flashcards
rate limiting enyzme for catecholamine synthesis and the sole inhibitor of it
tyrosine hydroxylase; alpha- methyltyrosine
MOA of the inhibitors of catecholamine storage (ICS)
short term increase in catecholamine but long term depletion of available pool of catecholamines
ICS used for hyper tension (3)
Reserpine, guanethidine, guanadrel
ICS used for ADHD and narcolepsy
amphetamine (narcoleptics) , methylphenidate
ICS used for allergic rhinitis and Nasal Congestion
Pseudoephedrine
ADR : GI hemorrhage, thrombocytopenia, dream anxiety disorder impotence and psychotic depression
Reserpine
ADR: kidney disease , apnea , orthostatic hypotention fluid retention, dizziness , blurred vision, impotence
Guanethidine , guanafrel
ADR: hyper tension, tachyarrhythmia , Gilles de la Tourettes syndrome, seizure psychotic disorder w/ prolonged use
Amphetamine, Methylphenidate
ADR: A-fib, VPB, MI, insomnia, tachyarrhtymia, hypertension
Pseudophedirine
Irreversibly inhibits VMAT but rarley used because of its association with psychotic depression
Reserpine
Displaces norepinephrine from the storage vesicles. and can lead to reduced CO
Guanethidine, Guanadrel
Displace endogenous catecholamines and also weakyl inhibit MAO and block reuptake at NET and DAT, dependence is possible
Amphetamine, Methylphenidate
Inhibitors of Catecholamine Reuptake and at what receptor
Cocaine
Imipramine
Amitriptyline
@NET
INhibitors of MAO
PICTureS of BoMBs PHenelzine Brofaromine Iproniazid Moclobemide clorgyline Befloxatone Tranylcypromine Selegine
Alpha1-adrenergic agonists (4) and Mechanism
- Phenylephrine, Oxymetazoline, Tetrahydrazoline, Methoxamine (MetPhenOxyTet)
- Increase peripheral resistance
INdicated for Opthalmic hyperemia and Nasal Congestion
Phenylephrine (can use in shock)
Oxymetazoline
Tetrahydrazoline
