Interchangeability between paracetamol tablets marketed in Palestine. Is there a quality reason for a higher price?

ABSTRACT

The objective of this study was to evaluate the quality of 10 commercial paracetamol products available on the Palestinian market. We carried out a survey on the price of all paracetamol tablet products and assessed their quality. To assess quality, all products were examined visually for their organoleptic properties, tested for weight uniformity, friability, disintegration, and dissolution profile, and assayed for paracetamol content. All imported products were 2 to 3 times more expensive than the locally produced generic products. Based on our testing procedure, all paracetamol products were equivalent to the innovator product except for 1 imported product which fell below the approved specifications developed for the innovator product. Although the majority of generic products met the dissolution specification requirement that 80% of the drug must dissolve in 30 minutes, 1 generic product failed. These results demonstrate that generic paracetamol tablets produced by local manufacturers are often comparable in vitroto the innovator product and have lower costs
