The pharmaceutical industry places patient safety above all other drug development considerations. When carried out in a scientific manner, Toxicity Studies for New Drugs help identify possible health risks before human clinical trials begin. Through these scientific tests, it is possible to determine the highest dose of a drug that can be tolerated by a patient without adverse health effects. Moreover, such tests help in establishing the safety margins of drugs for use in different patient groups.
Regulatory bodies such as the CDSCO have made these tests mandatory to prevent possible toxic reactions in future drug users. Therefore, every new drug formulation has to undergo a series of tests in the lab & in animals before they can be tested on human subjects. Through these tests, it is possible to quantify the risks of drug use, thus ensuring that only safe drugs reach the pharmacy shelves.
Understanding Subsequent New Drugs (SNDs)
Subsequent new drugs are new formulations of drugs already approved by the CDSCO. However, these drugs can also contain new claims, new dosages, or new routes of administration for drug users. Therefore, even though the original drug is safe in scientific tests, the new formulation has to undergo new tests for safety.
- SNDs contain drugs already approved in other countries for use by patients. They can also contain a new dosage form of a drug already approved by the CDSCO.
- Modified release formulations of drugs already approved by the CDSCO fall in the category of SNDs.
- New routes of administration for drugs already approved by the CDSCO also fall under the category of SNDs.
- Fixed-dose combination drugs already approved by the CDSCO fall in the category of SNDs.
These are considered new entities that uphold high standards of clinical practice in the industry. This process also prevents the inclusion of substandard medications that may react differently in the population. Furthermore, these toxicity studies for new drugs guarantee the retention of therapeutic efficacy, even with changes in the process.
Importance of Toxicity Studies for SNDs
- They confirm that the new process does not introduce any harmful impurities into the new product.
- Researchers conduct these toxicity studies for subsequent new drugs to prove the safety of new excipients.
- These studies help identify any damage to a specific organ that may result from a high dose of the product.
- These studies are essential in determining the initial dosage for human studies.
- Long-term studies help identify potential hazards, such as cancer and birth defects.
- These studies ensure that the new product is as safe as the original product developed by the pharmaceutical company.
- Companies can also avoid legal liabilities by demonstrating the rigorous conduct of these studies for the new product.
Regulatory Requirements and Guidelines
Compliance with Schedule Y:
Pharmaceutical companies are required to adhere to the protocols set by Schedule Y of the Drugs and Cosmetics Act. These protocols require conducting extensive Toxicity Studies for Fixed Dose Combinations to assess chemical compatibility.
Good Laboratory Practice Standards:
It is essential to conduct these safety studies in GLP laboratories. Therefore, only those results are considered by the officers if they are conducted in a GLP facility.
Acute and Systemic Testing:
Acute studies are conducted for a short period and are helpful in identifying the short-term effects of a high dose of a product on the body. Systemic studies are conducted to assess the long-term effects of a product on the liver, kidneys, and heart.
Specific Requirements for Combinations:
If two drugs are mixed for the first time, then specific toxicity studies for fixed dose combinations are required. This is done to make sure that two chemicals do not interact and form new toxins.
Role of Toxicity Studies in Drug Safety and Approval
The backbone of every successful drug application to health authorities is safety data. Without the results of Toxicity Studies for Subsequent New Drugs, a drug cannot be approved for marketing. Toxicity studies act as a protective shield for both the manufacturer and consumer. By investing in quality research, a company can create immense trust within the minds of both drug professionals and patients. Professional testing ensures that every drug tablet or injection works exactly as intended, without causing any unforeseen harm to patients.

Frequently Asked Questions
Q1. What is the main aim of the toxicity studies for new drugs?
Ans: The main aim is to determine the potential hazards the drug may cause. It assists the researcher in establishing the safe dosage level for the drug under investigation.
Q2. How long does the toxicity study take?
Ans: These studies can take anything from weeks to even two years. Long-term tests can take up to two years.
Q3. Are animal tests required for drug approval?
Ans: Yes, animal tests are required to determine the effect the drug will initially have on the human body.
Q4. What is the aim of the acute toxicity test?
Ans: This test is done by observing the effect the drug will cause if one dose is taken. It is done over a short term of 24 hours to determine the lethal dose.
Q5. What is the cost of the toxicity study in India?
Ans: This can cost anything between Rs. 5,00,000 to Rs. 50,00,000. Detailed systemic tests for new molecules can cost much more.
Q6. What is the role played by GLP in toxicity testing?
Ans: Good laboratory practice plays a crucial role by providing consistent and easily traceable data. It is a requirement for any data to be submitted to the authorities.
Q7. Do new versions of the drug undergo the same tests as the original drug?
Ans: No, the tests required for the new versions of the drug are different. They require tests to determine the safety level of the new drug. It is assumed the drug is safe, and the only change is the dose level.
Q8. What is the aim of the reproductive toxicity tests?
Ans: These tests determine whether a drug affects fertility or harms a fetus. These tests are critical for drugs intended for people of childbearing age.
Q9. Can a drug be rejected based on its toxicity data?
Ans: Yes, if a drug poses a high risk to vital organs, the project is terminated. This ensures that harmful drugs are never released to the public.
Q10. Why are fixed-dose combinations tested for their toxicity?
Ans: The combinations are tested to determine whether they will have a toxic interaction when they are mixed. Moreover, the two safe drugs can still be harmful when mixed.
