Background
Creation
of The National Drug Monitoring Centre
The National Health Surveillance Agency (ANVISA), created
in 1999, gradually becomes more structured. The National System
of Pharmacovigilance, managed by the Pharmacovigilance Unit, which
is a part of the Health Products Post-Marketing Surveillance Department,
was created in this period.
The most recent
tragedy that occurred in Brazil was in 2000, and it concerned
the use of meglumine antimonate: over 300 patients had serious
lesions caused by the injections. This fact reinforced the initiative
of developing drug monitoring processes in Brazil.
The Brazilian
National Drug Monitoring Centre was created in 2001 by Decree
696 in May, 7th by The Ministry of Health, and takes place in
Pharmacovigilance Unit to obtain legal background to expand our
field of action. After that we were admitted, in August 3rd, 2001,
as the 62nd country in the WHO International Drug Monitoring Programme
coordinated by the Uppsala Monitoring Centre, in Sweden, a WHO
Collaborative Centre.
Brazilian Pharmacovigilance Programme was planned to integrate
strategically four principles: safety, effectiveness, rationality
and quality of marketed drugs.
Operational
Guidelines
The
Pharmacovigilance Unit is responsible for planning, coordinating
and supervising the formulation and implementation of the guidelines
and operational technical norms on the safe use and surveillance
of drugs. The creation of a wide network for the communication
and reporting of information enables to detect, evaluate and trigger
the necessary measures if any product damages the health and well-being
of the drug users. This began as a strategy to accumulate information
on the safety, effectiveness, quality and rational use of marketed
medicines. Among all the strategies for 2002/2003, we should emphasize
four of these operational guidelines:
a) Spontaneous
reporting of adverse drug reactions: Using an adverse drug reaction
form, specially through the Internet, any health professional
can report adverse drug reactions directly to Anvisa. This method
aims mainly the identification of serious reactions of drugs marketed
in Brazil, whether or not they have been previously described.
Special attention shall be given to recently marketed drugs, for
early identification of poorly described reactions or others still
unknown that may be hazardous to public health.
b) Establishment
of a network of 100 Sentinel Hospitals: Distributed nationwide,
this network will monitor the quality and safety profiles of drugs
used in hospitals and promote their rational use. The hospitals
were chosen by their size according to the number of beds and
the number of internal medical training programs. This network
will also provide surveillance of medical devices (technovigilance)
and surveillance of blood (hemovigilance).
c) Establishment
of Regional Centres: one is in the state of Ceará and the
other is in São Paulo. It is expected that a total of 27
centres will be reached in the future, one in each state of Brazil.
d) Creation
of a net of Sentinel Pharmacies: Pharmacies who works with Pharmaceutical
Healthcare are going to contribute with earlier detection of adverse
drug reactions of prescription, over the counter, herbal and registry
free medicines.
Activities
The Pharmacovigilance Unit is not limited to assessing reports
of suspected adverse reactions, although this represents an indispensable
part of its attributions. Moreover, not only the binomial safety
and effectiveness is at the center of the Pharmacovigilance process
in Brazil, but also quality and rationality aspects were included
therein as important aspects in the challenge to assure suitable
products that offer lower risks to the population.
Along with
the Department of Inspection, of the National Health Surveillance
Agency, The Pharmacovigilance Unit monitors the processes of mandatory
and voluntary drug recalls in Brazil through the international
communication network. In order to evaluate safe and effective
products available in the market, they strive to identify problems
of quality deviations and drug counterfeiting and to carry out
"in loco" investigations of serious adverse events,
during epidemic drug-related outbreaks.
A review process
of the profile of benefits and risks of drugs already in the market
is being carried out by identifying products banned in other countries,
products requiring changes in their restrictions of use, and products
of unacceptable or no any therapeutic value and whose license
should be cancelled, especially drugs formulated with irrational
associations of active ingredients. Also, within the scope of
the market profile review, new regulatory laws are being consolidated,
with a view to the updating of the information contained in drug
usage directions and to the registry renewal, which shall include
the reassessment of their effectiveness and safety profile.
Rational drug
use has been object of training and multiple courses sponsored
by The National Health Surveillance Agency, with the objective
of enhancing health professionals' capability to prescribe in
a rational basis, to identify drug-related problems and to notify
adverse drug reactions to the National System of Pharmacovigilance.
