From million doses of annual antibiotics consumption goes waste as these could not be utilized or targeted to the infective organisms effectively due to various factors like efficient absorption, transportation to the target site, retention time, operation of efflux pump, metabolism etc. Thus, large portions of the drugs we apply are wasted and only a miniscule percentage is being targeted to the infective microbes. Also, the unutilized drug/antibiotic amount remains as a load in the body and environment acting as a selection pressure to facilitate emergence of drug resistance in parasites and their predominance, ultimately leading to failure of antibiotics against resistant infections. This also is responsible for side effects, illness and reduction in life expectancy being more acute in the older population. One of the ways, which has been feasible to reduce drug dosage, has been synergism between two therapeutic agents. However, if both have the antibiotic property, still the problem of continued selection pressure on microbes is likely to continue. So, the applicants thought of utilizing cow urine, which is not microbicidal but when present with a drug or active molecule, enhance its activity and availability (bioenhancers). This way, the selection pressure will be counter-balanced simultaneously reducing the dosage of antibiotics or drugs for minimizing the side effects, which has also high commercial importance. The present work has direct implication in reducing the dosage of antibiotics while increasing the efficiency of absorption of bio-active molecules, thereby reducing the cost of treatment and also the side-effects due to toxicity.
