Microbial and Physicochemical Analysis of Non-sterile Pharmaceutical Liquid Products in Karachi Pakistan

Abstract

The pharmaceutical products and their therapeutic efficacy were comprised' due to the involvement of both physicochemical and microbial characteristics of the pharmaceuticals. However, liquid preparations are highly at risk due to the high percentage of sucrose contains that is beneficial for the growth of microbes. The inspection was to find to judge the microbial and physicochemical qualities of samples of paracetamol and cetirizine sold in Karachi, Pakistan. Three hundred fifty (350) pharmaceuticals brand were investigating; their organoleptic properties such as density, color, pH, test and total content of active ingredients, total viable count, and type of microbe of samples. These tests were conducted followed by the standard techniques and procedure. Assess the brands of paracetamol and cetirizine samples were meet the standard microbial specifications. The result of the organoleptic test was sweet, according to the color sample was found green, pink, red, yellow, and transparent liquids. The density of samples fluctuated between (1.150 - 1.390) g/ml. Similarly, the pH of the samples was recorded between (4.72 - 6.10). The active ingredient concentration of both samples was observed, ranging from 99% - 104%. The microbial limit many tests were conducted for the observation; the absence of 5 specified microbes in non-sterile pharmaceutical preparation. Pseudomonas sp. Escherichia coli (E-coli), salmonella spp, Staphylococcus spp, and Candida Albicans. All the samples of paracetamol and cetirizine were found contaminated under the acceptable limit. This observation explained that the ten brands of paracetamol and cetirizine sold in the pharmacy of Karachi Pakistan were complying with specifications of pharmacopeia, about both physicochemical and microbial characteristics analyzed dosage form fit for used and acceptable for pediatric and geriatric patients.
