communicable diseases , which were the leading causes of mortalities , are not anymore , especially in developed countries . currently , non - communicable diseases are more prevalent , and most of them are related to changes in our daily habits and degenerative processes . most of these diseases are chronic , need continuous care and treatment with limited improvement and high costs [ 1 - 3 ] . the general assembly of the united nations in its resolution 65/238 recognized the primary role and responsibility of governments in responding to the challenge of non - communicable diseases and the essential need for the efforts and engagement of all sectors of society to generate an effective response . special emphasis has been concentrated on pharmacological treatments for most of chronic non - communicable diseases with the challenge to discover new drugs for treating , in most cases , chronic irreversible degenerative diseases associated with aging . worldwide hypertension is the most frequent chronic disease among aged population it is estimated that 35% of the general population over 40 years old suffer idiopathic arterial hypertension and need treatment for life [ 4 , 5 ] . over the last years pharmacological treatment angiotensinconverting - enzyme inhibitors ( aceis ) have replaced beta - blockers in many cases . the current scientific debate is about indications , effectiveness , safety and cost - effectiveness of angiotensin receptor blocker ( arb ) and aeci . recently arb is taking its place between known antihypertensive drugs especially in patients with other chronic diseases like renal insufficiency [ 6 , 7 ] . non - pharmacological measures for treatment of hypertension are well - known and include diet control with low salt diet and cholesterol diet , tobacco cessation , weight control and physical exercises [ 8 - 11 ] . it is estimated that 30% of hypertensive patients can control their blood pressure following non - pharmacological measures without the need for any antihypertensive drugs . over the last 30 years the number of diabetes mellitus ( dm ) patients and its prevalence are rapidly rising . ginter and simko ( 2010 ) reported that in the second half of the 20th century it became obvious that a relentless increase in dm type 2 affecting the economically affluent countries is gradually afflicting also the developing world . however , all these drugs have several side effects , which are usually related to other underlying pathologies in the same patient . dm type i is treated with insulin , which has been revolutionized over the last 10 years , with various forms of insulin and modes of administration [ 14 , 16 ] . non - pharmacological measures for control of blood glucose in diabetics , like diet and weight controls and regular physical exercise are hardly adopted by these patients [ 13 , 16 , 17 ] . it is estimated that in western countries > 40% of the general population are over weight . junk food , high carbohydrate and fat diet and lack of physical exercise are the main risk factors for this epidemic . of no doubt diet control and physical exercise could resolve this health problem . over the last years , several drugs were used to control weight , like thyroxin and metformine and new drugs like litramine . most of studies have shown that these drugs are not completely safe and could produce several side effects . other measures to treat obesity include surgical intervention like stomach reduction , liposuction and intestinal anastomosis . tobacco smoking prevalence reached 45% of the general population in many western countries . currently chronic obstructive pulmonary diseases ( copd ) treatment measures include bronchodilators with sympathomimetics and antiparasympathomimetics , together with corticosteroids in the form of oral , injection and inhalation therapy . side effects related to corticosteroids use like iatrogenic hypertension , and iatrogenic dm are well known . tiotropium is one of the specific treatments to delay the progress of the disease and to improve the pulmonary functions . recent meta - analysis reported a 52% increased risk of mortality associated with tiotropium mist inhaler in patients with copd . although weight reduction , physical exercise and pulmonary exercise in specific have been proved to be effective and improve pulmonary function tests by 30 - 40% , the use of pharmacological treatment in copd is by far more numerous than non - pharmacological measures . in 2010 , the spanish national health service ( nhs ) paid for 958 million prescriptions . most of these prescriptions were realized at primary healthcare . according to the spanish nhs , areas requiring improvement in primary care prescription include over - treatment of patients in low risk situations , poor patient information , polymedication and the appreciable percentage of preventable adverse effects . over the past few decades , developed countries have achieved remarkable improvements in terms of their life expectancy , with growing number of third age population . most older patients do have several concomitant chronic conditions and receive treatment mainly at primary healthcare by general practitioners / family physicians . multiple co - morbidities of older patients are usually associated with increased use of health care resources , multiple health care providers , polymedication and an overall increased risk of adverse events . a recent retrospective observational study performed in croatia from march 2005 to this study reported 2076 adverse drug reactions , 1209 of which ( 58.2% ) involved more than one drug . in conclusion , we currently look for pharmacological and surgical measures to treat most of chronic noninfectious diseases , as rapid and easy measures ignoring their side effects and costs , rather than adopting healthy habits and non - pharmacological measures .
summaryover the last years medicine has progressed very rapidly . 
 communicable diseases , which were the leading causes of mortalities , are not anymore , especially in developed countries . 
 currently , non - communicable diseases are more prevalent , and most of them are related to changes in our daily habits and degenerative processes . 
 most of these diseases are chronic , need continuous care and treatment with limited improvement and high costs . 
 the general assembly of the united nations in its resolution 65/238 recognized the primary role and responsibility of governments in responding to the challenge of noncommunicable diseases and the essential need for the efforts and engagement of all sectors of society to generate an effective response . 
 special emphasis has been concentrated on pharmacological treatments for most of chronic non - communicable diseases with the challenge to discover new drugs for treating , in most cases , chronic irreversible degenerative diseases associated with aging . 
 little care was given to non - pharmacological lines of treatment .
