Cycloserine is an antibiotic drug that falls under the category of medicines known as second-line antitubercular drugs. It specifically belongs to the class of antibiotics called cycloserines. It’s primarily used in the treatment of tuberculosis (TB), and is most effective when partnered with other TB medications. Cycloserine operates through inhibiting the formation of the bacterial cell wall, acting on two essential enzymes - alanine racemase and D-Alanyl-D-alanine synthetase. Its disruption of these enzymes ultimately leads to cell death, making it an effective bactericidal agent. Besides TB, cycloserine is occasionally used off-label for other conditions, often in instance where other treatments haven't shown efficacy.

The quality of Cycloserine is crucial for optimal efficacy and safety, with impurities and related compounds being of significant concern. Common impurities that can occur in cycloserine samples include isotopic impurities, byproducts from manufacturing, or degradation products. It is crucial to monitor cycloserine for these impurities to ensure safety and effectiveness. Regulatory authorities, like the US Food and Drug Administration and European Medicines Agency, have established strict guidelines concerning permissible levels of impurities in drug substances, and it is essential for manufacturers to comply with these regulations and regularly test their cycloserine formulations.
Cycloserine tablets are primarily used for treating tuberculosis (TB). They are often used in combination with other TB drugs, especially in instances of multi-drug resistant TB. Cycloserine works by inhibiting vital functions of the TB bacteria, leading to bacterial cell death.

No, cycloserine and cyclosporine are not the same. While both are pharmaceutical drugs, they have different uses. Cycloserine is an antibiotic used primarily for treating tuberculosis, whereas cyclosporine is an immunosuppressive drug often used to prevent organ rejection in transplant patients.
Cycloserine works by inhibiting the formation of the bacterial cell wall. It achieves this by interfering with the function of two essential enzymes – alanine racemase and D-Alanyl-D-alanine synthetase – leading to cell death and making it effective in killing bacteria.
