Abstract

This article addresses a risk based approach to establish a routine monitoring program of viable (I.e. microorganisms) in a controlled environment used to produce pharmaceutical products that are intended to be terminally sterilized. Current applicable quality system regulation & GMP require appropriate environment to be established, maintained and monitored for the manufacturing of the terminally sterilized pharmaceutical meanwhile the appropriate environmental monitoring plan is not clearly specified & a risk based approach will be a valuable tool to design a suitable program

Introduction

Current regulatory environment emphasize on the use of enhanced knowledge over the manufacturing processes & product performance that can help in identifying the risks associated to the patient safety & the product quality. This article will describe briefly the Quality risk management & apply its elements on a model which is the Environmental monitoring during the filling of terminally sterilized products [1]. Such approach will insure the following

A. Product quality and patient safety

B. Meeting the regulatory expectations

C. Minimize the manufacturing cost through minimizing the monitoring frequencies.

The following procedure will be followed during the Risk assessment procedure

A. Identify The process

B. Identify Risk

C. Implement Risk Assessment

D. Determination of the RPN (Risk Priority Number)

E. Establish the monitoring frequency according to the determined RPN

Procedure

Identify the process

High flow chart for the manufacturing process of the terminally sterilized products:

Identify risk

Risk factors: The following factors represent the variables to be considered during the risk assessment process:

A. Risk factor (A): Amount of microbial contamination on, or in, a source.

B. Risk factor (B): Ease of dispersion, or transfer, of microorganisms

C. Risk factor (C): Proximity (location) of source from critical area.

D. Risk factor (D): Effectiveness of control method.

Table 1:


Risk numbering: The following table showing the risk numbering procedure (Table 1)

Risk priority number (RPN) determination: The RPN shall be determined by multiplying the risk number of the four variables [2]: (Figure 1)

Figure 1:


RPN= Risk factor (A) * Risk factor (B) * Risk factor (C) * Risk factor (D)

Monitoring frequency according to the determined RPN: As a safety factor the frequencies shall be determined [3] according to the square root of the determined RPN: The following table showing the environmental monitoring frequencies according to the determined RPN [4]: (Table 2)
