Varenicline

Varenicline is a partial agonist of the α4β2 nicotinic acetylcholine receptor that is approved for the treatment of tobacco dependence.
It works by reducing cravings and withdrawal symptoms associated with smoking cessation.
Varenicline has been shown to be effective in helping people quit smoking and maintaining abstinence over the long term.
Researchers can use PubComapre.ai to easily locate relevant protocols from the literature, preprints, and patents, and leverage AI-driven comparisons to identify the best methods and products for their Varenicline research.
This can enhance the reproducibility and accuaracy of their findings.

Algorithms for prevalent conditions and smoking status used ICD-9 codes from inpatient and outpatient encounters during 12- and 24-month baseline periods (codes listed in Appendix table 1). The algorithm for coronary heart disease (CHD) included ICD-9 codes for previous MI, angina, and previous revascularization. Two algorithms for current smoking status were evaluated: one that included only ICD-9 codes, and one that included either ICD-9 codes or a filled prescription for nicotine replacement therapy or the smoking cessation drug varenicline during the baseline period. Acute MI events during follow up were identified from hospitalizations with an ICD-9 code for acute MI (410).
On a training set of 15 subjects, two physicians (JSF and MB) reviewed the full VA electronic medical record and achieved consensus on the validation of prevalent conditions at baseline and acute MI events during follow up. For the remaining subjects, the full VA electronic medical record was reviewed by one physician to validate prevalent conditions at baseline and acute MI events during follow up. The validation of prevalent conditions required physician documentation of the condition. Adapting criteria from previous studies,10 (link),11 (link) the validation of acute MI events required (1) physician documentation of acute MI, (2) presence of ischemic symptoms, and (3) troponin levels greater than 2x the upper limit of normal or an electrocardiogram with ST-segment elevation or new left bundle branch block. Validation criteria for each algorithm are listed in Appendix table 1.

LC-ESI-HRMS Method for the Determination of Varenicline Nitroso-Drug Substance Related Impurity, U.S. FDA, Aug. 6, 2021, www.fda.gov/media/151470/download (accessed Feb. 27, 2022) can be used to test for impurities.

Other analytical methods for the entire process can be used to test for impurities. The methods are validated as per ICH guideline.

For example, HPLC RS methods are used for quantifying the impurities. The nitrosamines, monomethyl and dimethyl tartaric acid esters are quantified by LCMS methods.

A solution of Varenicline free base (5.0 g) in methanol (50 mL) was stirred under hydrogen (6.0 kg/cm2) pressure in the presence of 10% Palladium on carbon (0.5 g, 50% wet) at 25-35° C. After 6 hours and the reaction mass was filtered through celite pad and rinsed with methanol (50 ml). The filtrate was distilled completely under reduced pressure and co-distilled with methyl tert-butyl ether to remove traces of methanol & water. methyl tert-butyl ether (50.0 mL, 10.0 volume) was added to the concentrated mass and stirred at 5-10° C. for 3 hours. The product was isolated by filtration and washed with chilled methyl tert-butyl ether by twice. The wet material was dried at 40° C. under vacuum. Yield: 4.2 g

Example 22

Varenicline free base (7 g) was dissolved in methanol (140 ml) at 25-30° C. In a separate flask, tartaric acid (4.92 g) was dissolved in 70 ml water at 25-30° C. Varenicline solution was mixed with tartaric acid solution at 25-35° C. The resulting clear solution was stirred for 30 min at 25-35° C. to form the Varenicline tartrate salt solution. Maltodextrin (119.84 g) was dissolved in water (420.53 ml) at 25-35° C. separately and added this Maltodextrin solution into Varenicline tartrate solution prepared earlier. The resulting clear solution was stirred for 30 minutes, filtered through a micron filter and washed with water (2×70 ml). The clear filtrate was subjected to spray drying using a spray dryer to obtain the amorphous Varenicline Tartrate Maltodextrin Premix (1:10) API. Yield: 130.0 g. Purity by HPLC: 99.99%.
