Diabetes sufferers may soon be able to inhale
life-saving drugs rather than having to give themselves several daily
injections, according to published research.
An American study of a new inhaler device for insulin found that it worked as well as the traditional method of injections.
The findings could offer hope to diabetes
sufferers who have to go through the discomfort and inconvenience of two
or three daily jabs to maintain their blood glucose levels.
The number of diabetes sufferers in Africa
remains uncertain, although and IDF estimate from 2000 put the figure at
7.5 million diabetic adults between 20 and 79 years of age. It is
thought that this figure is now much larger.
The WHO (World Health Organisation) and the
IDF (International Diabetes Federation) estimate that the diabetes
population will double over the next twenty five years.
Half a million diabetics have to give themselves daily injections of insulin to maintain their glucose levels every day.
Diabetes sufferers cannot convert the glucose
in their blood into energy because the hormone insulin is either not
produced or does not work properly.
Sufferers say the gruelling regime affects their everyday life, social relations and even their own self-image.
Insulin inhalers have been tried from as
early as 1925, but the devices have not been effective enough in getting
the insulin into the body’s system.
Now a US company has developed an inhaler which uses a new dry-powder form of insulin.
Researchers from the University of Miami
studied 73 patients with insulin-dependent Type 1 diabetes, the most
severe form of the illness.
Half were given the new inhaler to use before
meals – when injections are normally administered – while the others
stuck with their normal round of daily jabs.
The findings, published in the medical
journal The Lancet, found that the inhaler worked as well as the needle
in maintaining blood glucose levels and preventing sufferers from
falling into potentially-fatal diabetic comas.
This is great news for diabetics, but people
should remember there are still further trials to be done. It will still
be several years before an inhaler of this kind could become available.
