cognitive function (Davis, 1987). A later patent was taken out by the same author<br />

for the same indication <strong>and</strong> routes of administration, but covering new derivatives<br />

of galanthamine or their analogues (Davis <strong>and</strong> Joullie, 1988).<br />

Patients with Down’s Syndrome (trisomy of chromosome 21) can develop<br />

histological changes resembling those seen in the brains of Alzheimer’s patients.<br />

Learning ability in patients with Down’s Syndrome may be improved by galanthamine<br />

(Fransits <strong>and</strong> Mucke, 1997).<br />

One prolific investigator from Icel<strong>and</strong> has taken out a series of patents addressing<br />

the treatment of mania (Snorrason, 1994), fatigue syndromes (Snorrason,<br />

1992a), various forms of arthritis (Snorrason <strong>and</strong> Murray, 1997), attention deficit<br />

disorders (Murray <strong>and</strong> Snorrason, 1999a) <strong>and</strong> proteolytic diseases (Murray <strong>and</strong><br />

Snorrason, 1999b), as well as methods for countering the side-effects of benzodiazepine<br />

therapy (Snorrason, 1992b,c). Acute mania is a difficult condition to treat<br />

<strong>and</strong> often requires high doses of neuroleptics given for a number of days. The<br />

author claims galanthamine to be a faster treatment than other drugs. Stress is<br />

placed within the patent on the activity of galanthamine at nicotinic receptors.<br />

Fatigue is a common enough symptom in primary care medicine, but its clinical<br />

importance cannot be over-estimated. It can be a major aspect of significant morbidity.<br />

Fatigue associated with viral infections, especially the Epstein Barr virus,<br />

can be prolonged <strong>and</strong> debilitating. Mononucleosis in late-teens or the University<br />

years can result in long periods of marked fatigue leading to considerable impairment<br />

of performance. In its severe form – myalgic encephalitis (ME) or Chronic<br />

Fatigue Syndrome (CFS) – patients experience debilitating fatigue lasting for<br />

more than 50% of the day over a period of six months or more. Such patients are<br />

usually in the ‘bread-winning’ years of life <strong>and</strong> may be unable to work for several<br />

years <strong>and</strong> can even be dependent upon a wheelchair. No effective treatment presently<br />

exists for this condition. Galanthamine is claimed as a treatment for fatigue,<br />

muscle pains <strong>and</strong> sleep disturbances in CFS. Claims are made for galanthamine, or<br />

its derivatives, to be effective in the treatment of various fatigue syndromes,<br />

including those associated with HIV infections <strong>and</strong> pre-eclampsia.<br />

Cholinesterases also have proteolytic enzyme activity. Two patents from the<br />

Icel<strong>and</strong>ic author, working with a British colleague, address the potential for galanthamine<br />

to have a positive effect on disease conditions in which proteolytic<br />

enzymes appear to play an important role. The first addresses the role of raised<br />

proteolytic enzyme <strong>and</strong> cholinesterase activity in the synovial fluid in the joints of<br />

patients with rheumatoid arthritis. Claims are made for galanthamine in the treatment<br />

of rheumatoid <strong>and</strong> osteo-arthritis, arthritis associated with auto-immune<br />

disease, psoriasis, chronic inflammatory bowel disease, ankylosing spondylitis, as<br />

well as a range of other joint disorders. Such treatment, if successful, could be<br />

expected to be disease-modifying rather than simply palliative. The second patent<br />

addresses head-on the concept that proteolytic activity in other diseases is associated<br />

with acetyl cholinesterase activity, <strong>and</strong> that this could be blocked or inhibited<br />

by treatment with galanthamine, epigalanthamine or norgalanthamine. Such diseases<br />

would include psoriasis, Crohn’s Disease <strong>and</strong> ulcerative colitis.<br />

Attention deficits <strong>and</strong> hyperactivity disorders (ADHD) are thought to affect 5%<br />

of children in the USA <strong>and</strong> Europe. Moreover, such behavioural problems can be<br />

carried into adult life where they may manifest themselves as alcohol or drug<br />

abuse <strong>and</strong> other anti-social behavioural traits. Current therapy in childhood
