Ignoring the therapeutic index (TI) when making new drugs can have serious effects, especially for patient safety. The TI is the balance between the amount of a drug that works well and the amount that can cause harm. It helps us understand how safe a drug is for people.
Higher Risk of Side Effects: If a drug has a narrow TI (meaning the safe dose and the harmful dose are close together), it can lead to more side effects. For example, digoxin has a small TI, so if the dose isn't carefully managed, it can cause toxicity.
Drugs May Be Taken Off the Market: If drug companies don’t check the TI thoroughly, they may need to pull drugs off the market later on. A well-known case is the anti-inflammatory drug, rofecoxib (Vioxx), which was linked to heart problems that weren’t fully known when it was developed.
Legal Trouble and Costs: Companies that overlook the TI might get sued for the harm their drugs cause. This can lead to a lot of financial issues for them.
Harm to Reputation: Pharmaceutical companies can hurt their reputations if they don’t pay attention to the TI. This can make it harder for them to do future research and develop new drugs.
In short, not paying attention to the therapeutic index during drug development can lead to many problems. This shows how important it is to do careful safety checks.
