Quality assurance of veterinary drugs
Animal drugs, especially veterinary biological products, must be subjected to national assays performed by an officer designated by the Minister. NVAL is the only national facility that performs tests. The drugs designated by the Minister shall not be sold or given, or stored or exhibited for the purpose of sale or giving, unless they satisfy the tests performed by NVAL. The rejected drugs are discarded in the presence of a pharmaceutical inspector.
National Sampling Assay
For removing harmful drugs in the process of manufacturing and marketing, and ensuring quality, NVAL is performing quality assays of drugs which were sampled by a pharmaceutical inspector at the manufacturer's factory or outlet. Drugs which do no meet the requirement of the tests performed by NVAL are collected and discarded.
Quality tests by Order
The Minister may order that tests be performed for veterinary drugs. Tests for veterinary antibiotics were abolished on 1st, July. 1995. However, the Minister has requested that NVAL performs quality tests for some of them. Animal blood typing antibodies should also be tested. Rejected products are discarded in the presence of a pharmaceutical inspector.
Recently, a number of countries which have requested a certificate for the quality of products issued by the national facility has been increasing. As a result, NVAL performs necessary tests to Issue certificates.
NVAL also may perform quality tests upon the request from manufacturer (importer).
Veterinary drugs,both manufactured and imported,have to be approved before they are sold in Japan. Biological products, such as vaccines,must pass "national assay". Antibiotic products must pass an evaluation by order of the Minister of Agriculture, Forestry andFisheries.Other drugs are also tested periodically to assure quality. If they are rejected in these assays and tests,they are subject to action,such as recall and disposal.
The NVAL is the only national laboratory to conduct assays and tests to assure the quality, efficacy and safety of veterinary drugs.
