Poison or Antibiotic? A Guide to “Class” Entries Preface Most entries in the Poisons List and the First, Second and Third Schedules to the Pharmacy and Poisons Regulations are in the form of individual drugs and their salts, e.g. “Abacavir; its salts”. However, some entries are in the form of a “class”, e.g. “Barbituric acid; its salts; its derivatives …”. In such cases, it is not always clear which drugs are members of the class (e.g. amobarbital, barbital, pentobarbital, phenobarbital, etc. are poisons, being derivatives of barbituric acid). Likewise, the Antibiotics Ordinance applies to the substances specified in Schedule 1 to the Antibiotics Regulations, to their salts and derivatives, and to the salts of such derivatives. Again, it is not always clear which drugs are derivatives of an antibiotic named in the Schedule (e.g. demeclocycline, doxycycline, tigecycline, etc. are antibiotics, being derivatives of “Tetracycline” named in the Schedule). This Guide provides a list of such drugs which are available as registered pharmaceutical products in Hong Kong. Drugs which are not available as registered pharmaceutical products in Hong Kong are also included in this Guide as far as possible. It should be noted that it is not possible to compile a complete list of all these drugs, simply because there is no limit to the number of “derivatives” a parent chemical can have. This Guide should be read in conjunction with the Poisons List, the First, Second and Third Schedules to the Pharmacy and Poisons Regulations, and Schedule 1 to the Antibiotics Regulations, if the poison/antibiotic classification of a particular pharmaceutical product is to be determined. Pharmaceutical Service Department of Health September 2007 Step-by-step guidance on determining the poison/antibiotic classification of a pharmaceutical product 1. Identify the (first) drug contained in the pharmaceutical product. 2. If this drug is found in the Poisons List, continue to look for it in the First and Third Schedules to the Pharmacy and Poisons Regulations to determine the “poison” classification of the pharmaceutical product containing this drug. Then look for it in the Second Schedule to determine if the product is exempted from control as poison under that Schedule. 3. If the drug is not found in the Poisons List, look for it in Schedule 1 to the Antibiotics Regulations. 4. If the drug is found in Schedule 1, the pharmaceutical product will be an antibiotic. 5. If the drug is found neither in the Poisons List nor in Schedule 1 to the Antibiotics Regulations, look for it in the Index to the Guide. 6. If the drug is found in the Index to the Guide, note the Item Number against it, then turn to the Guide itself to identify the Item number and the corresponding Entry in the Poisons List or Antibiotics Schedule of the drug. 7. Repeat steps 2 to 5 with respect to this entry, to determine the classification of the pharmaceutical product containing this drug. 8. If the drug is not found in the Index to the Guide, look for its synonyms (in “Martindale”, the Merck Index, etc), and repeat steps 2 to 7 with respect to each synonym. 9. If none of the synonyms is found in the Index to the Guide after repeating steps 2 to 7, the pharmaceutical product containing the drug will be neither a poison nor an antibiotic. 10. For a multi-component product, repeat the above steps with respect to each component. The “poison” classification of the product itself will be that of the most stringently classified component. In addition, if one component is classified as antibiotic, the product itself will also be classified as an antibiotic.
