BB DRUG LISTS Flashcards
What is L-Dopa?
This is a synthetic precursor of dopamine that is often used in the treatment of Parkinson’s disease
What drugs are usually given in combination with L-Dopa and why?
With a DOPA-carboxylase inhibitor such as carbodipa or bensarazide to prevent peripheral carboxylation which can have emetic effects
What are the potential side-effects of L-Dopa?
Nausea and vomiting (due to peripheral activation of postrema), postural hypotension, psychosis (due to over-activation of the mesolimbic pathway) and sleep disturbances
What are the potential motor complications of L-Dopa use?
On-off effects, dyskinesia, wearing off effects and dystonia
Name 4 different types of dopamine agonist
Rotigotine, bromocriptine, perogolide and ropnirole
What is rotigotine, it’s use and it’s administration method?
It’s a dopamine receptor agonist used in the treatment of Parkinson’s disease and it’s given via a transdermal patch
What are selegiline and rasagiline?
These are monoamine oxidase b inhibitors (MAOb); they prevent residual dopamine from being oxidised
What is the use of selegiline and rasagiline?
They may be used in the treatment of Parkinson’s disease as they are MAOb inhibitors and therefore increase the dopamine availability in the synaptic cleft and may reduce on-off symptoms
What are entacapone and tolcapone?
These are COMT inhibitors that are used in the treatment of Parkinson’s disease in combination with L-DOPA
What is amantadine?
It’s an anti-viral drug that works to block dopamine reuptake by the presynaptic neurone and increases dopamine release and therefore can be used in the treatment of Parkinson’s disease
How may anticholinergic drugs be used in the treatment of Parkinson’s disease?
Dopamine loss leads to the hyperactivity of cholinergic cells and therefore cholinergic muscarinic antagonists will reduce the effects of this and reduce tremor
Name some anticholinergic drugs that may be used in the treatment of Parkinson’s disease
Benzatropine, benzhexol, orphenadrine, procyclidine and trihexyphenidyl
What is benzatropine?
Anticholinergic drug (muscarinic receptor antagonist) used in the treatment of PD
What is benzhexol?
Anticholinergic drug (muscarinic receptor antagonist) used in the treatment of PD
What is orphenadrine?
Anticholinergic drug (muscarinic receptor antagonist) used in the treatment of PD
What is procyclidine?
Anticholinergic drug (muscarinic receptor antagonist) used in the treatment of PD
What is trihexyphenidyl?
Anticholinergic drug (muscarinic receptor antagonist) used in the treatment of PD
What are some of the potential side-effects of anticholinergic drugs used in the treatment of Parkinson’s?
Dry mouth, constipation and urinary retention
What is tetrabenazine?
This is a drug used in the treatment of Huntington’s disease which inhibits synaptic vesicle monoamine transporter
What are the monoamine neurotransmitters?
Dopamine, serotonin, norepinephrine, and histamine
What is baclofen?
This is a GABAb receptor agonist that is used in the treatment of Huntington’s disease to reduce the involuntary movements by inducing more inhibitory neurotransmitter release
What drug types are used to treat Parkinson’s disease?
L-Dopa (synthetic dopamine precursor), dopamine agonists, MAOb inhibitors, COMT inhibitors, anti-vitals and anticholinergic (muscarinic antagonist) drugs
What drug types are used to treat Huntington’s disease?
Amine transporter inhibitors (tetrabenazine), GABAb agonist (baclofen), antipsychotics (dopamine receptor antagonists) and antidepressants
What are olanzapine and haloperidol?
They are antipsychotic drugs
