market from different manufacturers. In this study we investigated and assessed
the Pharmaceutical quality of different brands of Ciprofloxacin 500mg tablets (Ciproquin®,
Ciflox® and Ciprogram®) that been marketed in Saudi
Arabia in order to obtain the quality of the products. The reasonable access to health care in any country of the
world is a human right and governments should do their best to ensure the

Alma ata conference  (WHO
and UNICEF conference) at 1978 develop principles for primary health care (PHC)
to ensure high quality and safe drug use, principle such as availability of the
Essential Drugs List (EDL) (4).

The quality of drug means that
the drug contains the claimed quantity of the
active ingredient on its label and from the dosage of one unit to the other and
it has to be free from foreign substance and to maintain it potency and
appearance of drug and availability until the use  and when administrated it should has the entire

market of many developing countries (8). This lead to widespread distribution
of substandard or / and counterfeit drug products (8).

Drugs must meet the efficacy
