British researchers have suggested higher dosage of antibiotics drugs used to treat infections caused by bacteria--for overweight people, as small dose may increase resistance in bacteria.

Experts claim that antibiotic doses should be taken in accordance to the patient's body-weight to take into consideration rising obesity levels and prevent superbugs as high body-weight affects the concentration of drugs in the body and how fast the medicine show their efficiency.

The study opined that doses should be taken prior to doctor’s consent especially for obese patients, though a lot of work and direction will be required to train GPs.

In addition, electronic prescribing can assist with the required calculations and as bodyweight is already taken into account for children the same approach cannot be too difficult for adults.

Research laid emphasis on the fact that very little drug might not be sufficed to treat the infection but it retaliates back by making the organism resistant.

Dr Matthew E Falagas and Dr Drosos Karageorgopoulos, of the Alfa Institute of Biomedical Sciences, in Athens, Greece wrote, “We believe that tailoring the dosing of antimicrobial agents in adults to the physical characteristics of individual patients could be an important way to achieve maximum effectiveness and safety of antimicrobial therapy”.
