Department of Pharmacology
What we do
Pharmacology is the health profession that links the health sciences with the chemical sciences and ensuring the
safe and effective use of pharmaceutical drugs.
Performing excellence is a priority of the department and we put maximum effort on laboratory analysis for the
To acquire new knowledge in pharmacology, by conducting and promoting innovative researches to establish
efficacy, safety and effectiveness of medications in human.
The final aim of the department of pharmacology is to be a well recognized and distinguished unit in the field of
pharmacology and therapeutics in Sri Lanka by providing reliable investigations and better training for the
medical, paramedical and post graduate students.
The department of pharmacology includes 1 Consultant Pharmacologist, 1 Medical Officer, 1 Senior Medical Laboratory Technologist, 2 Medical Laboratory Technologists, 1 Lab Orderly and 2 Health care

The laboratory of clinical pharmacology performs laboratory analysis with the specific task to provide therapeutic
drug monitoring (TDM) of the levels of a drug in the serum and plasma. This is to ensure optimal dosing schemes for
the patient (i.e., to select the dose and dosing intervals). The interpretation is a crucial part to help the physician to
optimize the therapeutic effect and minimize the risk of toxicity. Levels of metabolites in urine are done to support
the diagnosis of neuroendocrine and carcinoid tumours.
What We Do
1. Immuno suppressive agents
Above mentioned drug levels are useful for guiding dosage adjustments to achieve optimal
immunosuppression while minimizing dose dependent toxicity.
We use Enzyme Linked Immuno Sorbent Assay(ELISA) for the quantitave determination of Tacrolimus/
Cyclosporine in human whole blood by Chemiluminescent Microparticle Immuno Assay(CMIA) technology with
flexible assay protocols.
Above mentioned drug levels are done to ensure appropriate dosage to minimize drug
We use Enzyme Linked Immuno Sorbent Assay (ELISA) for the quantitave determination of Gentamicin/
Vancomycin in human serum by Chemiluminescent Microparticle Immuno Assay (CMIA) technology with flexible
3. Anti-epileptic drugs
Above mentioned drug levels are used in the diagnosis and treatment of overdose/ toxicity
and in monitoring drug levels to help ensure appropriate therapy in Epilepsy.
We use Enzyme Linked Immuno Sorbent Assay(ELISA) for the quantitave determination of Na Valproate/
Carbamazepine in human whole blood by Chemiluminescent Microparticle Immuno Assay(CMIA) technology
with flexible assay protocols.
4. Metabolites done in urine
Vanillyl Mandelic Acid(VMA)
5 Hydroxy Indole Acetic Acid(5HIAA)
Elevations of above metabolites in urine are supportive in the diagnosis of neuroendocrine
tumours such as pheochromocytoma, paraganglioma, neuroblastoma and carcinoid tumors.
We use Chromatographic Spectrometry for the quantitative determination of VMA/ Metanephrine/ 5HIAA in 24
hourly collected urine sample.
