uses
alcoholism

apomorphine used notable success treatment alcohol , morphine addiction. @ first part of pavlov style conditioned-reflex treatment, later continued emetine practitioners such voegtlin in us, gradually replaced recognition various practitioners in europe drug having other effects. however, form of treatment fell out of favour, , on 1980s.

parkinson s disease

first used treatment parkinson s disease 1951, clinical use first reported in 1970 cotzias et al., although emetic properties , short half-life made oral use impractical. later study found combining drug antiemetic domperidone improved results significantly. commercialization of apomorphine parkinson s disease followed successful use in patients refractory motor fluctuations using intermittent rescue injections , continuous infusions.

therapeutic use in parkinson s disease effective because of drug s strong dopaminergic action. when administered subcutaneously, apomorphine effective dopamine agonist. within 3–20 minutes of injection apomorphine demonstrates magnitude of effect (ability convert patient parkinson s disease on state) comparable l-dopa. single subcutaneous injection lasts 90 minutes. while apomorphine can used in combination l-dopa, intention reduce l-dopa dosing, stage patient parkinson s disease experiencing great deal of dopa-induced dyskinesias , off periods. following successful apomorphine challenge, training of patient , caregiver, , careful dose titration, patient can maintained in on state use of apomorphine pump effective monotherapy.

alzheimer s disease

when proteins in cell undergo misfolding due damage, misprocessing, or mutation can lead alteration of protein’s secondary structure , change amino acid residues accessible. in many cases of protein aggregation, hydrophobic residues, on interior of soluble proteins, become arranged on solvent exposed surface. can lead interactions between hydrophobic regions of multiple proteins, entropically favorable reduce surface area of hydrophobicity exposed. formation of few molecules form oligomer still soluble, grows , continues aggregate product fall out of solution, causing damage cell manifesting in proteopathic diseases. recent studies have shown pre-fibril aggregates toxic through hydrophobic interactions various cellular components causing cytoskeletal rearrangements , loss of cell-to-cell contacts.

apomorphine reported inhibitor of amyloid beta protein (aβ) fiber formation , potential therapeutic alzheimer s disease (ad) under amyloid hypothesis. apomorphine , small molecule relatives found promote oligomerization of aβ40 group of molecules, inhibit more advanced fibril formation occurring. mechanism of protection offered small molecules thought due autoxidation occurs @ hydroxyl groups. once functional group altered, inhibitory effect seen decrease, reducing either indirect or direct interference of fibril formation.

the protective effects of apomorphine tested in mouse models mutations in genes related ad, such amyloid precursor protein (app) gene, implicated in amyloid molecule build-up. apomorphine seen improve memory function through increased successful completion of morris water maze. levels of aberrant proteins lead neuronal disruption tested in brains of mice. treatment seen decrease intraneuronal levels of more aggressive aβ42 molecule when compared control mice. result consistent finding protein linked ad, tau protein, seen decrease apomorphine treatment. apomorphine shown promote aβ degradation , inhibit formation through anti-oxidative properties. moderate doses shown provide improvements while overuse provided no benefits , may cause toxicity.

opioid addiction

in deposition: testimony concerning sickness in introduction later editions of naked lunch, william s. burroughs wrote apomorphine treatment effective cure opioid addiction has encountered:

the apomorphine cure qualitatively different other methods of cure. have tried them all. short reduction, slow reduction, cortisone, antihistamines, tranquilizers, sleeping cures, tolserol, reserpine. none of these cures lasted beyond first opportunity relapse. can never metabolically cured until took apomorphine cure... doctor, john yerbury dent, explained me apomorphine acts on brain regulate metabolism , normalize blood stream in such way enzyme stream of addiction destroyed on period of 4 5 days. once brain regulated apomorphine can discontinued , used in case of relapse.

he goes on lament fact of writing, little no research has been done on apomorphine or variations of drug study effects on curing addiction, , perhaps possibility of retaining positive effects while removing side effect of vomiting.

despite claims throughout life, burroughs never cured addiction , using opiates within years of apomorphine cure . however, insisted on apomorphine’s effectiveness in several works , interviews.

veterinary

apomorphine drug of choice inducing vomiting in dogs. used after ingestion of various toxins or foreign bodies.
