Pharma Collq3 Flashcards
Non opioid analgesic are
Paracetamol and metamizol
Opioid receptor agonists are
Codaine, fentanyl, morphine, tramadol,buprenorphine
Coanalgesics
Anti epileptic drugs, antidepressants, central Aalpha adrenoreceptor agonist
5HT receptor agonists
Sumatriptan
Opioid receptor antagonist
Naloxone
NSAIDS
Ibuprofen and dickofenac
CGRP receptor antagonist
Erenumab
CGRP antagonist
Galcanezumab
Chronic pain are
Inflammatory pain, musculoskeletal pain, headache, neuropathy
Neuropathic pain is due to
Somatosensory nerve damage
Most common neuropathy
Post herpetic neuralgia, diabetic neuropathy, trigeminal neuralgia
Neuropathic pain has
Excessive sensitization of neurons and ectopic signal foci
Ectopic signal foci is caused by
Over expression of sodium channels
Against neuropathic pain
Anti epileptic and antidepressants drugs are used
For nociceptive pain
NSAIDS and paracetamol
Nociceptive system connect to
Spinothalamic and spinomedullary tract neurons
Classical or typical antipsychotic drugs
Haloperidol and chlorprothixene
Atypical (2.gen) drugs
Clozapine,Olanzapine,Quetiapine,Aripiprazole
Non specific antipsychotic drugs
Melperone and sulpiride
Psychotic states are
Schizophrenia and bipolar disorders
4groups of psychotic symptoms
Positive,negative, cognitive and affective
Positive symptoms are
Hallucinations, delusion and catatonia (stupor and excitement)
Catatonic excitement
Chaotic, unpredictable, stereotypical psychomotor activity
Negative symptoms are
Alogia,anhedonia, emotional indifference and social isolation
Cognitive symptoms are
Attention and concentration disorder,working memory deficiency
Affective symptoms are
Depression, anxiety and suicidality
Division of AP into typical and atypical is based on
EPS historical,butewrong
Nowadays based on negative symptoms
Drugs that cause disease independent negative symptoms are
Typical antipsychotic drugs
4major pathways in dopaminergic system
Mesolimbic,mesocortical,nigrostriatal,tuberohypophseal(tuberoinfundibular)
Drugs used against positive symptoms are
D2 receptor antagonist working on mesolimbic tract
Typical drugs have
Prolonged D2 receptor blockade or slow off dissociation kinetics
Typical drugs can cause
Negative symptoms as well
D2 receptor blockade SE
EPS,hyperprolactinemia
HT2a receptor blockade SE
Anxiety and insomnia
H1receptor blocker SE
Drowsiness, appetite,weight gain
M cholinoreceptor blocker SE
Dry mouth, urinary retention,blurry vision, constipation,can also cause negative and cognitive symptoms
Alpha 1 adrenoreceptor blocker SE
Orthostatic hypotension, reflector tachycardia, dizziness
H1 receptor blocker is used to gove
Sedation
Antiemetic
Against vomiting
Typical AP indication
Schizophrenia and acute mania
Atypical AP indication
Schizophrenia and bipolar disorders
Aripiprazole is a
D2 partial agonist and HT2a antagonist
Aripiprazole use
Schizophrenia, bipolar disorders and acute mania
Clozapine main side effect
Agranulocytosis,convulsion ,severe constipation (it can also cause wet cushion syndrome due to M4 stimulation), sedation (H1 block), orthostatic hypotension due alpha 1 adrenoreceptor block))
Clozapine is used only
Resistant schizophrenia treatment
Melperone use
Schizophrenia and neurotic stage and confusion in seniors
Sulpiride uses
Affect negative and affective symptoms without acting on 5HT 2a receptor ,so use in schizophrenia and depressive disorders
Akathisia
Desire to move constantly
Dystonia
Uncontrollable, abnormal involuntary movement
Parkinsonism
Bradykinesia,tremor, rigidity
EPS treatment
Trihexyphenidyl(central M cholino blocker)
Metabolic disorders caused by AP
Weight gain, hyperprolactinemia, hypercholesterolemia,risk of diabetes
Treatment of NMS
Benzodiazepine(against anxiety and agitation),central D2 receptor agonist -bromocriptine,Danteolene- peripheral muscle relaxant(against muscle rigidity and hyperthermia)
