[New therapeutical approaches to type 2 diabetes]

[Treatment of type 2 diabetes: revision of current therapeutical options and priorities]

The paradigm of type 2 diabetes mellitus treatment is based in an adequate meal plan and the regular practice of physical exercise. The benefits of these measures are of evident as it is the perseverance in their compliance. In the daily practice, this reality favours the early implementation of a pharmacological therapy that, in the opinion of different experts, would be simultaneous to the introduction of life style changes. In the last years, new drugs have been developed. On the one hand, there are agents with beneficial effects not only on blood glucose control but also on the components of metabolic syndrome. Other drugs, according to different experts, have doubtful therapeutical contribution. The appearance of new drugs to treat obesity, associated with diabetes or not, extends other possibilities of choice to take into account. The great variety of options makes the decision of the adequate therapy more difficult. In the last decade, many therapeutic guidelines have been developed, with convergences and divergences that may mislead the inexpert practitioners. In this review we propose some practical advise in diet and exercise, and an evaluation of the different drugs and rules of intervention proposed in the different therapeutic guidelines. The ultimate goal is to facilitate and direct type 2 diabetes management.

Prevalencia y consumo de medicación antidiabética en la Comunidad de Madrid (1996-2002)

OBJECTIVES/AIMS

To determine the prevalence of diabetes mellitus treated with drugs and the prescription of drugs in diabetes (oral anti-diabetics and insulin) in the Community of Madrid between 1996-2002.

METHODS

We used the indirect method for estimating the rate of prevalence of diabetes based on antidiabetic drug in the Madrid Community. We studied the consumption or oral antidiabetics (OH) and insulin (IN) in all the Madrid Community Area from 1996 to 2002. To make consumption uniform we used the daily doses/1,000 inhabitants/day (DHD). The total consumption was obtained using the official billing data and the annual population data provided by the "Institute Madrileño de Salud".

RESULTS

The prevalence of diabetes mellitus increased 62.5% in the period studied, ranging from 1.6% in 1996 up to 2.6% in 2002. The DHD of oral drugs increased 87.8% from 12.2 in 1996 to 23.07 in 2002. The DHD of insulin decreased 28.2% from 3.99 in 1996 down to 3.11 in 2002. The OH/IN ratio increased 138%, from 3.11 to 7.42 in 2002. There is a tendency to increase biguanide and sulfonilureas with low risk of hypoglycemia. The total cost of insulin and oral medication increase every year, the increase of diabetic patients and the cost/DDD of the new drugs are factors that increase the total cost of diabetes.

CONCLUSIONS

The prevalence of diabetes mellitus treated with drugs increased in the Community of Madrid. There is a progressive use of oral drugs versus insulin, and a tendency to prescribe biguanide, sulfonylureas, especially gliclazide and glimepiride. A tendency to substitute insulin with insulin analogues is also seen in the use of insulin. The cost of diabetes increases yearly.
