  9. Drug Information and Control of Promotion

  10. Product information and control of promotion Objectives • To understand the role of product information • To understand the minimum content of product information • Appreciate the need for the control of product promotion • Understand the different methods available for the control of promotion

  11. The quality of a drug is not only its identity, purity, strength, safety, efficacy. It is also: • Compliance with regulation • product information • Labelling • patient insert,etc.

  12. A drug is a chemical substance + information The quality of the information accompanying a drug is as important as the quality of the active substance Product information • Label • leaflets/inserts

  13. Product information • Summary of product characteristics submitted as part of the marketing authorization application • Agreed statement between the competent drug regulatory authority and the marketing authorization holder on the approved conditions of use of a product • Content and status is usually defined in law and should be publicly available • Dictates how the product may be promoted to health professionals and the public • For drug to be exported, a copy of the approved product information must accompany the certificate of marketing authorization (WHO-Certification Scheme)

  14. Product information content: (WHO Ethical criteria) • International Non-proprietary Name(INN) of each active substance • Pharmacological data - brief description of pharmacological effects and mechanism of action • Clinical information: - Indications - Dosage regimen and relevant pharmacokinetic data: • average and range for adults and children • dosage interval • average duration of treatment • special situations,e.g., renal failure, etc that require either increased or reduced dosage

  15. Product information content: (WHO Ethical criteria) • Contra-indications • Precautions and warnings (reference to pregnancy, lactation, etc. adverse effects • Drug interactions including drug used for self-medication • Over dosage: • brief clinical description of symptoms • non-drug treatment and supportive therapy • specific antidotes

  16. Product information content: (WHO Ethical criteria) Pharmaceutical information • dosage form • strength of dosage form • excipients • storage conditions and shelf-life • pack sizes • description of the product and package • legal category • name and address of manufacturer(s) and importer(s)

  17. Labelling:information on the immediate or outer packaging/container • usually defined in drug laws • The content has to be consistent with the product information • Serves as a source of information for the distributor/dispenser, prescriber, and consumers

  18. Labelling:content General: primary and secondary containers • The name of the product • Active ingredient (s)( INN) and amount present • Net contents-number of dosage units, weight, volume • Batch number • Expiry date - uncoded form • Storage conditions or handling precautions • Directions for use • Warnings and precautions • Name and address of manufacturer/company/suppliers

  20. Promotion is a persuasive communication that seeks to influence the attitudes, beliefs and behaviour of people Unaware awareness Interest Trial Use

  21. Promotional methods • Direct • TV advertising, radio, print media (journals, newspapers, magazines), Internet, direct mailings, pamphlets • Personal selling - sales representatives, house to house peddlers • Indirect • Disease awareness campaigns • Sponsorship of information materials-helplines • Links with patient groups • Sales promotion - gifts and samples • Public relations - sponsored symposia, ADR studies

  22. Control of promotion • Government DRA control - pre-approval - surveillance • monitoring very difficult • requires resources • Industry self-regulation - UK- ABPI, Australia-APMA, IFPMA • Needs strong association • Enforcement difficult - no sanctions • Enforced self-regulation - self regulation with sanctions • Tripartite regulation- industry, DRA, public interest groups

  23. Control of promotion • Promotion should be consistent with national health policies and comply with drug regulations • Should comply with the particulars listed in the product information • Should contain reliable claims, without misleading or unverifiable statements • should contain no omissions which lead to health risks • Should not be designed so as to disguise its real nature, for example, as educational or scientific activities • should encourage rational use of the medicinal product

  24. Patient information • Should be accurate & comprehensive • Improve health and enhance outcomes of medical treatment • Empower consumers to make informed decisions • Improve communication between the patient and the health care provider • Should be written in a simple, clear and easily readable language Principles
