Isoniazid is a medication commonly used in the treatment of tuberculosis, a bacterial infection that primarily affects the lungs. Given the prevalence of tuberculosis in certain regions of the world, the availability and effectiveness of isoniazid is paramount in preventing the spread of the disease and improving public health outcomes. Its relevance to everyday life lies in its crucial role in combating a potentially life-threatening illness, thereby safeguarding individual well-being and promoting community health.

💡 Commercial Applications
Isoniazid, also known as INH, is primarily used for its pharmaceutical benefits in the treatment of tuberculosis. This antibiotic drug is highly effective in killing the bacteria responsible for the disease, making it a key component in the standard treatment regimen for tuberculosis.
In addition to its medical applications, isoniazid also has commercial and industrial uses. It is commonly used in the production of various chemicals, including pyridine and its derivatives. These chemicals are then used in the manufacture of pharmaceuticals, pesticides, and other products.
Furthermore, isoniazid can be employed as a corrosion inhibitor in industrial settings, particularly in the oil and gas industry. Its ability to prevent the degradation of metal surfaces has made it a valuable asset in protecting equipment and infrastructure from damage caused by corrosive substances.
⚗️ Chemical & Physical Properties
Isoniazid is a white to off-white crystalline powder with no distinct odor.
The molar mass of Isoniazid is approximately 137.14 g/mol, and its density is around 1.21 g/cm³. Compared to common household items, Isoniazid has a higher molar mass and density than water and sugar.
Isoniazid has a melting point of approximately 170-173°C and a boiling point of about 300°C. In comparison to common household items, Isoniazid has a higher melting and boiling point than most liquids such as water and ethanol.
Isoniazid is slightly soluble in water and has low viscosity. Compared to common household items, Isoniazid has lower solubility in water than substances like salt and sugar, and its viscosity is lower than substances like honey or syrup.
🏭 Production & Procurement
Isoniazid, commonly known as INH, is a pharmaceutical agent used in the treatment of tuberculosis. The production of Isoniazid involves a chemical synthesis process that begins with the condensation of isonicotinic acid hydrazide with propanal, followed by subsequent purification steps to obtain the final product.
Isoniazid can be procured through pharmaceutical companies or suppliers who specialize in providing bulk quantities of active pharmaceutical ingredients. The transportation of Isoniazid typically occurs through regulated channels, such as air or sea cargo, ensuring proper handling and storage conditions to maintain the integrity of the product during transit.
Upon procurement, Isoniazid is usually packaged in sealed containers or drums to prevent contamination and degradation. Proper documentation, including certificates of analysis and safety data sheets, accompanies the shipment to ensure compliance with regulatory requirements and quality control standards. The transportation of Isoniazid is subject to international regulations governing the handling and transport of hazardous materials to ensure safety and security.
⚠️ Safety Considerations
Safety considerations for Isoniazid include the potential for hepatotoxicity, peripheral neuropathy, and drug interactions. It is essential to monitor liver function tests regularly, especially in patients with pre-existing liver disease. Peripheral neuropathy can be prevented or managed by administering pyridoxine (vitamin B6) concurrently with Isoniazid. Additionally, caution should be taken when using Isoniazid with other medications that can interact with it, such as rifampin or antiretrovirals.
The pharmacology of Isoniazid involves inhibition of mycolic acid biosynthesis in the bacterial cell wall, specifically by inhibiting the enzyme enoyl-ACP reductase. This disruption leads to cell death of the bacteria responsible for causing tuberculosis. Isoniazid is well-absorbed orally and is metabolized in the liver by acetylation. It has a half-life of approximately one hour and is excreted primarily through the urine.
Hazard statements for Isoniazid include its potential to cause irritation to the respiratory system, skin, and eyes upon contact. Ingestion or inhalation of Isoniazid can result in nausea, vomiting, and abdominal pain. Chronic exposure to the compound may lead to liver damage and neuropathy. It is crucial to handle Isoniazid with care, use appropriate personal protective equipment, and ensure proper ventilation when working with the substance.
Precautionary statements for Isoniazid involve storing the medication in a cool, dry place away from direct sunlight and heat. Keep the medication out of reach of children and pets to prevent accidental ingestion. It is important to follow prescribed dosages and not exceed recommended limits to minimize the risk of adverse effects. Patients should be educated on the potential side effects of Isoniazid and advised to seek medical attention if they experience any concerning symptoms.
🔬 Potential Research Directions
One potential research direction for Isoniazid is the investigation of its mechanisms of action in treating tuberculosis, particularly in understanding how it targets mycobacterial enzymes and disrupts cell wall synthesis.
Another avenue of research could delve into the development of more effective drug delivery systems for Isoniazid in order to improve its bioavailability and reduce potential side effects in patients.
Furthermore, exploration into the potential of combining Isoniazid with other antibiotics or adjunct therapies to enhance its bactericidal activity and combat drug-resistant strains of tuberculosis could be a fruitful line of inquiry.
🧪 Related Compounds
One similar compound to Isoniazid based upon molecular structure is Pyrazinamide. Pyrazinamide, also known as PZA, is an anti-tuberculosis medication that works by disrupting the synthesis of bacterial proteins. It is often used in combination with other antibiotics for the treatment of tuberculosis.
Another compound with a similar molecular structure to Isoniazid is Ethionamide. Ethionamide is a second-line medication for the treatment of tuberculosis and works by inhibiting the synthesis of mycolic acids in the cell wall of the bacteria. It is often prescribed for patients who have multidrug-resistant tuberculosis.
A third compound that shares a molecular structure with Isoniazid is Thiacetazone. Thiacetazone is also used in the treatment of tuberculosis as a second-line drug and works by inhibiting the synthesis of mycolic acids in the bacterial cell wall. It is often used in combination with other antibiotics for the treatment of drug-resistant tuberculosis strains.
