Susceptible groups of patients, such as children and the elderly, are at greater risk of adverse reactions during therapeutic use.Ofloxacin, like some other fluoroquinolones, may inhibit drug-metabolizing enzymes, and thereby increase blood levels of other drugs such as cyclosporine, theophylline, and warfarin, among others. These increased blood levels may result in a greater risk of side effects. Careful monitoring of serum glucose is advised when ofloxacin or other fluorquinolones are used by people who are taking sulfonylurea antidiabetes drugs. The concomitant administration of a nonsteroidal anti-inflammatory drug with a quinolone, including ofloxacin, may increase the risk of central nervous system stimulation and convulsive seizures. The fluoroquinolones have been shown to increase the anticoagulant effect of acenocoumarol, anisindione, and dicumarol. Additionally, the risk of cardiotoxicity and arrhythmias is increased when co-administered with drugs such as dihydroquinidine barbiturate, quinidine, and quinidine barbiturate.Current or past treatment with oral corticosteroids is associated with an increased risk of Achilles tendon rupture, especially in elderly patients who are also taking the fluoroquinolones. Contraindications
As noted above, under licensed use, ofloxacin is now considered to be contraindicated for the treatment of certain sexually transmitted diseases by some experts due to bacterial resistance. Caution should be used in people with liver disease. The excretion of ofloxacin may be reduced in patients with severe liver function disorders (e.g., cirrhosis with or without ascites). Ofloxacin is also considered to be contraindicated within the pediatric population, pregnancy, nursing mothers, patients with psychiatric illnesses and in patients with epilepsy or other seizure disorders.
Olivieris data suggested deferiprone leads to progressive hepatic fibrosis. History
Deferiprone was approved for medical use in the European Union in August 1999.It was approved for medical use in the United States in October 2011. Generic versions were approved in August 2019.The safety and effectiveness of deferiprone is based on an analysis of data from twelve clinical studies in 236 participants. Participants in the study did not respond to prior iron chelation therapy. Deferiprone was considered a successful treatment for participants who experienced at least a 20 percent decrease in serum ferritin, a protein that stores iron in the body for later use. Half of the participants in the study experienced at least a 20 percent decrease in ferritin levels. References
