Title: Framework of antimalarial drug policy


1
Framework of antimalarial drug policy
  • Dr H. Atta
  • MO/RBM
  • WHO/EMRO

2
AMDP- Definition
  • An antimalarial treatment policy is a set of
    recommendations and regulations concerning the
    availability and rational use of antimalarial
    drugs in a country

3
Rationale of AMDP
  • Case management is a key component of malaria
    control
  • Few antimalarials are suitable for wide-spread
    use in public health
  • Development of new antimalarials is expensive,
    slow and difficult
  • Having updated antimalarial drug policy is
    essential to regulate availability and encourage
    rational use to avoid development of
    antimalarial resistance

  • Antimalarial Drug policy (AMDP)

AMDP_ Purpose
  • The primary purpose is promptly, effectively and
    safely treating malaria patients by selecting and
    making accessible to the populations at risk of
    malaria
  • safe,
  • effective,
  • good quality, and
  • affordable antimalarial drugs

6
Effective treatment
  • The definition varies in different
    epidemiological situations
  • In areas of intense transmission
  • clinical cure, i.e. clinical remission (no
    appearance of signs and symptoms in the 14 days
    following treatment.
  • In areas of low transmission parasitological or
    radical cure, i.e. elimination of all parasites
    from the body.

7
Drug policy- aims
  • Reduce morbidity,
  • Halt the progression of uncomplicated disease
    into severe and potentially fatal disease,
    thereby reduce malaria mortality,
  • Reduce the impact of placental malaria infection
    and maternal malaria-associated anaemia through
    PIT,
  • Minimize the development of antimalarial drug
    resistance.

8
The categories for the treatment
  • All treatment categories
  • Drugs for 1st, 2 nd, and 3rd line treatment,
  • Severe malaria,
  • Pregnant women,
  • Presumptive treatment,
  • Self-treatment,
  • Over-the-counter treatment,
  • Mass treatment ( in epidemics).

9
Most important
  • The choice of first line treatment has the
    greatest economic implications and the greatest
    public health implications.

11
Developing and Updating National Treatment
Guidelines
  • The essential components
  • Analysis of technical, social and economic issues
    related to malaria control and anti-malarial
    drug resistance
  • Analysis of the political environment for
    decision-making
  • Consensus-building among relevant stakeholders
  • (policy-makers, researchers, control staff,
    donors, private providers, industry and user
    representatives,
  • A supervisory body to oversee the development,
    implementation and revision of the policy,
  • A regulatory body to ensure adherence to the
    policy

12
Developing/revising AMDP Information needed
  • Epidemiological situation
  • Prevalence, incidence, mortality, seasonality,
    parasite species, efficacy to currently used
    antimalarial drugs
  • Access
  • properties of available alternative drugs
  • Analysis of provider and consumer behaviors
  • Analysis of health system capacity to implement
    the revised policy ( regulatory and legislative
    framework.

13
Information on drug characteristics
  • Efficacy of the current first line drug
  • Efficacy of the alternative drugs
  • Cost
  • Quality
  • Side effects
  • Cross resistance
  • Drug interactions
  • Contraindications
  • Effect on Special groups
  • Useful therapeutic life
  • Acceptability
  • Compliance
  • Dosage regimen

14
Assessment of the health system capacity to
implement the policy
  • Health system needs political support, financial,
    managerial, and technical resources to implement
    the policy to ensure availability of drugs at end
    user level
  • Careful analysis of many systems
  • Health care delivery
  • Financing
  • Human resources
  • Drug supply system
  • Supervision
  • Referral
  • Transport
  • Communications

15
Implementation-1
  • The key aspects
  • Compliance
  • Financial, human and technical resources
  • Health care infrastructure
  • Drug regulation, supply, distribution and quality
    assurance

16
Implementation-2
  • Establishment of effective public-private
    partnerships,
  • Education and training of health care staff and
    other providers,
  • Education and training of community residents,
  • Intercountry actions and information exchange to
    optimize implementation,
  • Monitoring and evaluation of the policy and its
    impact.

17
The Process of Change Needs Monitoring
  • Continuous monitoring and consensus-building
  • In vivo therapeutic efficacy studies should be
    conducted throughout the country in order to
    provide an indication of the geographical pattern
    of resistance.
  • The tests should be carried out at through
    sentinel sites, if not possible at regular
    intervals (18 months to 2 years) to provide a
    longitudinal perspective

18
Re-evaluation of AMDP
  • Signals
  • Indication of increase in sever malaria morbidity
    and mortality
  • Consumer and provider dissatisfaction with the
    current policy
  • Evidence from therapeutic efficacy tests
  • The availability of safe, effective, acceptable
    and affordable alternatives.

19
When to change
  • No well-defined criteria for determining the
    level of
  • clinical
  • or
  • parasitological
  • failures for replacing the first-line drug

20
Level of change
  • A cut-off level of 25 treatment failures is a
    widely quoted but it is an arbitrary figure.
  • The dynamic process of change should be analysed
    on the basis of the proportion of established
    clinical failures
  • The actual cut-off point will depend on many
    factors

21
Position of the countries in relation to TFR
22
  • Grace periodLow levels of drug failures, 5.
  • determine baseline data and trends in drug
    efficacy
  • Alert periodTreatment failure rates of 615.
  • Evaluate the expected adverse effects of
    increased drug resistance

23
  • Action periodTreatment failures of 1624.
  • Evaluate potential drug alternatives and channels
    of drug distribution
  • Be ready for preparing a plan for intervention
    when resistance to the first-line drug becomes
    intolerable.
  • Change periodtreatment failure 25 or above,
  • Change the first line drug
