Antiepileptic Flashcards
Status seizures or status epilepticus
Continuous or repeated epileptic seizures for atleast 30 minutes without regaining consciousness in between
Different form of epilepsy
Focal, generalized, combined,forms of unknown origin
Generalized epilepsy two form
Grand mal(tonic clinic), petite mal Absence
Tonic seizures
Increase muscle tone
Clonic seizures
Increase muscle twitching
Vegetative seizures
Has peculiar epigastric sensation
Sodium channel blockers in antiepileptic
Carbamazepine, valproic acid , Lamotrigine, Topiramate
T type calcium channel blockers in antiepileptic
Ethosuximide and valproic acid
High voltage calcium channel blockers in antiepileptic
Gabapentin, Lamotrigine, Topiramate
GABA a receptor allosteric modulator
Phenobarbital and Topiramate
GABA transaminase inhibitor
Valproic acid
SV2A action in antiepileptic drigs
Levetiracetam
Ampa /kainate receptor antagonist
Topiramate
Focal epilepsy can be treated by
Phenobarbital, Gabapentin,, Carbamazepine, valproic acid, Lamotrigine, Topiramate and levetiracetam
Tonic clinic form is treatment
Phenobarbital, carbamazepine, valproic acid, Lamotrigine, Topiramate and levetiracetam
Absence epilepsy treatment
Ethosuximide and valproic acid, Lamotrigine
Status epilepticus treatment
Phenobarbital, valproic acid, levetiracetam
Ethosuximide is a
T type (low voltage calcium channel blocker , work only on absence seizures
Phenobarbital is a
GABA allosteric modulator,treats ,focal ,tonic clinic and status epilepticus
Gabapentin is a
High voltage calcium channel blockers,works only on Focal epilepsy
Carbamazepine is a
Sodium channel blocker,works only on Focal and tonic clinic epilepsy
Lamotrigine is a
Sodium channel blocker and high voltage calcium channel blockers ,treats focal, tonic clonic and absence epilepsy
Levetiracetam is a
SV2A antagonist,focal, tonic clonic and status epilepticus
Topiramate is a
Sodium channel blocker and high v calcium channel blockers,GABA A allosteric modulator,AMPA receptor antagonist -focal epilepsy,Tonic clonic E
Valproic acid
Na channel blocker,LV calcium channel blockers,GABA transaminase inhibitor,, treatment of all type of epilepsy
Levetiracetam and phenobarbital can be used in treatment of
Focal, tonic clonic and status epilepticus
Lamotrigine treat
Focal , Tonic clonic and absence
Nti seizures drugs acting on status epilepticus
Diazepam, midazolam, valproic acid, phenobarbital, lorazepam levetiracetam
SE valproic acid
Teratogenic effect
Carbamazepine use
Bipolar disorders, neuropathic pain(trigeminal neuralgia), general TC and focal epilepsy
Gabapentin use
Focal epilepsy, neuropathic pain(diabetic neuropathy and post herpetic neuralgia), chronic pain syndrome
COMT inhibitor
Entacapone and tolcapone
Central acting cholinoreceptor blocker
Trihexyphenidyl
MAO inhibitor
Selegiline
NMDA receptor antagonist
Amntadine
Dopamine precursor or dopamine receptor agonists
Levodopa/benserazide,carbidopa,pramipexole
Parkinsons disease symptoms
Tremor, bradykinesia rigidity,postural instability
Carbidopa doesn’t cross
BBB and inhibits peripheral metabolism ofL-dopa,so that more dopamine available in CNS
L dopa can be used as antiparkinsonian and al see o it reduces
EPS
Carbidopa and benserazide are
Levodopa metabolism inhibitors or decarboxylase inhibitors
Dopamine induced GIT SE
Nausea, vomiting
Dopamine induced cardiovascular SE
Arrythmia and hypotension
L dopa can cause
NMS
Wearing off means
Exacerbation of disease
On off phenomena
Acute cycles of exacerbation of symptoms throughout the day
Levodopa induced dyskinesia
Involuntary movement during on time and bradykinesia during off time
Levodopa use
Parkinson disease and Parkinsonism
Trihexyphenidyl use
EPs, parkinsonism
Antidementia agents
NMDA receptor antagonist -memantine
Anticholineserases-donezepil,rivastigmine
SE of ACH esterase inhibitor
Cholinergic hyperactivation
Use of donezapil
Alzheimer’s dementia, vascular dementia, Parkinson’s dementia
NMDA receptor channel blocker memantine use
Alzheimer’s dementia
