Random use of antibiotics causes insensitivity and inefficiency (resistant) of the drugs on different microorganisms that increase vulnerability of patients, experts told in a workshop .
Quoting a study conducted by the University of Dhaka in collaboration with University of Nottingham, UK, speakers said frequent use of antibiotics makes different microorganisms resistant to those drugs and do not let human body to respond to those drugs.
It forces the patients to go for another antibiotic that actually increases duration to cure the disease, treatment cost and dissatisfaction among the patients, they added.
The study titled ''Antibiotic prescription pattern in district hospitals in Bangladesh" revealed that
Azithromycin, one of the most commonly used antibiotics, has developed 40% resistance against gram-positive microorganisms. That is why it is not working against different infectious diseases properly.
Ciprofloxacin, the most commonly prescribed second-generation drug that worked effectively against E Coli and gram-negative microorganisms, has become resistant in 80 percent cases. So the patients now are depending on Levofloxacin, the third generation antibiotic to cure the infections, it revealed.
Amoxicillin and Ampicilin have also becomes resistant in this country.
The study conducted from July to December 2009 at six district hospitals also revealed that one patient was providing with more than one antibiotic at those hospitals rationally or irrationally.
