If you are studying pharmacy, working in the pharmaceutical industry, or preparing for a career in drug regulation in Nepal, you may have heard about the National Medicines Laboratory (NML). It is one of the most important institutions involved in checking the quality of medicines available in Nepal.
The National Medicines Laboratory is Nepal's government drug testing and analysis laboratory. Its work is closely related to pharmaceutical quality control, drug regulation, laboratory testing, Good Laboratory Practices (GLP), vaccine lot release and research.
For pharmacy students and professionals, understanding the role of NML is particularly useful because it connects laboratory testing with the regulatory system of medicines in Nepal.
What is the National Medicines Laboratory?
The National Medicines Laboratory (NML) is the principal government organization responsible for scientific research, testing and analysis of medicines in Nepal.
It operates under the government drug regulatory system and works closely with the Department of Drug Administration (DDA).
According to the official information published by the Department of Drug Administration, the laboratory was established in 1964 AD and was previously known as the Royal Drug Research Laboratory (RDRL). The laboratory has different technical areas, including chemical analysis, microbiology, pharmacology and instrumental analysis.
The Drugs Act, 2035 (1978) provides the legal basis for the government's drug research and testing laboratory. The Act identifies the Drug Research Laboratory as the principal government body for scientific research, testing and analysis of drugs.
A brief history of NML
The institution has a long history in Nepal's pharmaceutical regulatory system.
It was initially established as the Royal Drug Research Laboratory under the Department of Plant Resources. Later, it was brought into the health sector and became associated with the Department of Drug Administration.
Over the years, its responsibilities expanded from basic drug analysis to broader pharmaceutical quality control, laboratory assessment, method validation, training and other regulatory activities.
Today, it is commonly known as the National Medicines Laboratory (NML).
Why is NML important in Nepal?
Medicines must be safe, effective and of acceptable quality before they reach patients. Simply manufacturing or importing a medicine is not enough; its quality may need to be verified through appropriate testing.
This is where NML plays an important role.
NML conducts or supports drug quality testing and analysis of medicines obtained through Nepal's regulatory system. Its work helps authorities assess whether medicines meet applicable quality requirements.
The laboratory's official role includes regulatory drug analysis, pre-marketing analysis, analysis of samples provided by government and other organizations, training, research and development, and support for pharmaceutical laboratory quality.
For anyone working in pharmaceutical Quality Control (QC) or Quality Assurance (QA), NML is therefore an important part of Nepal's overall medicine quality system.
Major functions of the National Medicines Laboratory
NML performs several activities related to pharmaceutical quality and drug regulation.
1. Testing and analysis of medicines
One of the main responsibilities of NML is to test and analyze medicine samples.
Testing may involve different pharmaceutical quality parameters depending on the product and applicable analytical requirements. Different laboratory sections may use techniques such as chemical analysis, instrumental analysis and microbiological testing.
The purpose is to determine whether the tested medicine meets the required quality standards.
2. Regulatory drug analysis
NML receives samples associated with the regulatory activities of the Department of Drug Administration.
These may include samples collected during inspections, samples related to public complaints, samples from imported medicines and samples collected as part of post-market surveillance.
This makes laboratory testing an important part of pharmaceutical regulation in Nepal.
3. Pre-marketing drug analysis
NML also performs pre-marketing analysis of pharmaceutical samples provided through the regulatory system.
According to NML, this includes both pharmacopoeial and non-pharmacopoeial medicine samples provided by DDA.
This type of analysis can help provide scientific information about medicine quality before or during the regulatory process.
4. GLP audit of pharmaceutical laboratories
Another important responsibility is the assessment and auditing of pharmaceutical testing laboratories.
GLP means Good Laboratory Practice.
A laboratory must have appropriate procedures, trained personnel, suitable equipment, proper documentation and controlled working practices to produce reliable analytical results.
NML conducts GLP-related audits and assessments of pharmaceutical laboratories. This is particularly relevant to pharmaceutical QC professionals because proper laboratory practices are essential for generating trustworthy test results.

5. Analytical method validation
Analytical methods must be demonstrated to be suitable for their intended purpose.
NML performs or supports analytical method validation and method verification as part of its laboratory activities.
This area is especially important for pharmaceutical analysts because methods used for testing medicines need to produce reliable and scientifically acceptable results.
6. Vaccine lot release
NML also has responsibilities related to vaccine lot release verification and certification.
Vaccine quality is particularly important because vaccines are biological products that require careful quality assessment.
The official NML website lists vaccine lot release verification and certification among its services.
7. Research and development
NML is not limited to routine testing.
The laboratory also carries out research and development activities related to medicines and drug analysis. According to NML's official information, research activities can include collection and analysis of market samples.
8. Training and technical support
NML also conducts training and supports the development of laboratory skills.
Training related to Good Laboratory Practices (GLP) can help pharmaceutical laboratories and laboratory personnel improve their knowledge and working practices.
The laboratory also provides educational institutions with opportunities for observation and interaction, which can be useful for pharmacy students.
Where does NML get medicine samples?
NML can receive medicine samples from several sources.
These include:
- Samples collected by the Department of Drug Administration during inspections
- Samples related to public complaints
- Samples associated with imported medicines
- Samples collected for post-market surveillance
- Samples from local pharmaceutical manufacturers
- Samples from government and other public institutions
- Samples from research organizations and industries
- Samples collected by NML during market surveys
The official NML description confirms that samples can come from DDA, private pharmaceutical industries and various government, research and other organizations.
What types of laboratory sections are found at NML?
Drug testing requires different scientific techniques, so NML has different laboratory areas.
The official Department of Drug Administration information identifies sections such as:
- Chemical analysis
- Microbiology
- Pharmacology
- Instrumental analysis
NML's current services also include drug testing and analysis, method validation, GLP audit, vaccine lot release, research and development, training and educational visits.
For pharmaceutical professionals, instrumental analysis is particularly important because techniques such as HPLC, UV-Visible spectroscopy and other analytical methods are commonly associated with modern pharmaceutical quality control.
You can also read my article on HPLC in Pharmaceutical Quality Control for more pharmaceutical QC-related information.
NML and pharmaceutical quality control in Nepal
NML and pharmaceutical company QC laboratories have different responsibilities, but their work is connected.
A pharmaceutical company's QC laboratory routinely tests raw materials, packaging materials, in-process samples and finished products according to approved procedures.
NML, on the other hand, performs regulatory and other authorized testing and analysis of medicine samples. It also evaluates laboratory standards and supports the broader national medicine quality system.
Therefore, NML can be considered an important link between laboratory science, pharmaceutical quality control and drug regulation in Nepal.
Why should pharmacy students know about NML?
Pharmacy students often learn subjects such as pharmaceutical analysis, pharmacology, microbiology, quality control and drug regulation.
NML brings many of these subjects together in practical laboratory and regulatory work.
Students interested in careers in pharmaceutical QC, QA, regulatory affairs, drug inspection, laboratory analysis and government pharmaceutical services should understand the role of NML.
