Several drugs have been withdrawn from the market due to significant safety concerns. Based on available information, these include Flupirtine, Gatifloxacin, Gemtuzumab ozogamicin (Mylotarg), and Glafenine. Each withdrawal was initiated to protect public health following the identification of serious adverse effects that outweighed their therapeutic benefits.
Notable Drug Withdrawals
The process of drug approval is stringent, yet unforeseen safety issues can emerge after a medication is widely used by the public. When such risks are identified—ranging from severe side effects to a lack of clinical benefit—regulatory bodies may mandate a drug's withdrawal to safeguard patients.
Here's a summary of specific drugs that have been taken off the market:
| Drug Name | Withdrawn Year | Primary Reason for Withdrawal |
|---|---|---|
| Flupirtine | 2018 | Liver toxicity |
| Gatifloxacin | 2006 | Increased risk of dysglycemia |
| Gemtuzumab ozogamicin (Mylotarg) | 2010 | No improvement in clinical benefit; risk for death |
| Glafenine | 1984 | Anaphylaxis |
Specific Cases of Withdrawn Drugs
Further details regarding the reasons for these significant drug withdrawals include:
- Flupirtine: This analgesic drug was withdrawn from the market in 2018 primarily due to concerns regarding severe liver toxicity. Prolonged use or use in certain patient populations led to a heightened risk of liver damage.
- Gatifloxacin: A fluoroquinolone antibiotic, Gatifloxacin, was removed in 2006. The key reason for its withdrawal was an increased risk of dysglycemia, which refers to significant disturbances in blood sugar regulation, including both hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar).
- Gemtuzumab ozogamicin (Mylotarg): Initially withdrawn in 2010, Mylotarg, a chemotherapy drug, was taken off the market due to a lack of demonstrated improvement in clinical benefit for patients and an associated risk for death. It is notable, however, that Gemtuzumab ozogamicin was later returned to the market in 2017 after further clinical trials confirmed its benefit in specific patient populations, along with revised dosing and prescribing information to manage risks.
- Glafenine: This non-steroidal anti-inflammatory drug (NSAID) was withdrawn much earlier, in 1984, due to its association with severe and potentially fatal anaphylaxis, a systemic allergic reaction.
These instances underscore the critical importance of ongoing pharmacovigilance and the responsiveness of regulatory bodies to emergent safety data, ensuring that only medications with a favorable risk-benefit profile remain available to patients.
