1. Introduction

Guideline documents are meant to provide assistance to industry and professionals on how to comply with governing statutes and regulations. Guideline documents also provide assistance to staff on how NHRA mandates and objectives should be implemented in a manner that is fair, consistent and effective.

The purpose of this guideline is to provide clear definitions of the products for which the Pharmaceutical Products Regulation Office (PPR)* of the NHRA has responsibility and to provide an understanding of the factors that guide classification decisions by NHRA in relation to any pharmaceutical products for human use.

Before a pharmaceutical product can be placed on the market in the Kingdom of Bahrain, an application must be made for a license to the NHRA. Such applications should contain the data necessary to support the quality, safety and efficacy for the product. These data are reviewed by the NHRA and a conclusion reached based upon the likely balance of the benefits versus risks associated with the product. As indicated above, the license must be granted prior to the product being placed on the market. The NHRA requires that the interests of consumers and users of pharmaceutical products should be protected, notably in the following areas:

- A pharmaceutical product should be of appropriate quality such that its contents and its

pharmaceutical performance should conform to acceptable standards,

- The risk of using the product should be acceptable and reasonable, taking into account that the use of any medicine carries a risk, which should be considered in the light of the likely benefit,

- There should be a demonstrable benefit for pharmaceutical products. If a medicinal claim is

made, the consumer is entitled to expect a benefit.

- Any product registered as food supplement in country of origin (reference competent authority, refer Annex III) will be considered as such in the Kingdom of Bahrain, with condition to Annex II.

This document should be read in conjunction with other applicable guideline documents.

* PPR: Pharmaceutical Product regulation is the responsible office for medicine licensing at NHRA

the procedure for classification of such products.

Listed below are the product categories accepted for classification:

classification upper intake level as per annex I will be followed e.g. If the product is from Japan then

limits as per USP DSC will be considered.

3. If the upper intake level is not detectable/not mentioned in USP DSC, then NHRA classification upper

thereafter to relevant section.
