[0001] DESCRIPTION

[0002] SOLID COMPOSITIONS COMPRISING IMEGLIMIN

[0003] Field of Invention

[0004] The present invention relates to pharmaceutical composition comprises imeglimin or pharmaceutically acceptable salts thereof.

[0005] Background of the Invention

[0006] The eradication of Type 2 Diabetes Mellitus (T2DM) represents a therapeutic strategy aimed at completely eliminating this condition, which poses a significant global public health concern. T2DM is associated with serious metabolic complications, including hyperglycemia, insulin resistance, and an increased risk of cardiovascular disease. The primary objective of eradication therapy is to alleviate symptoms and prevent related long-term consequences. Current treatment protocols typically involve the administration of two or three pharmacological agents in combination with lifestyle modifications. The success of eradication depends heavily on selecting the optimal therapeutic regimen and ensuring patient adherence to the treatment plan, which may include monitoring blood glucose levels and adjustments to dietary and physical activity habits

[0007] Imeglimin is a novel oral anti-diabetic agent that targets mitochondrial bioenergetics to improve glycemic control in patients with Type 2 Diabetes Mellitus (T2DM). Unlike traditional medications, Imeglimin acts on multiple organs — primarily the liver, muscle, and pancreas — to enhance insulin sensitivity, increase insulin secretion, and reduce hepatic glucose production. This multifaceted mechanism makes it particularly effective in addressing both insulin resistance and beta-cell dysfunction, which are core defects in T2DM. It is used for managing hyperglycemia and has shown promise in improving overall metabolic parameters in patients. Its unique pharmacokinetics and mode of action provide better glycemic control, especially in patients requiring comprehensive management of their diabetic condition. The molecular structure of imeglimin hydrochloride is shown below.

[0027] Detailed Description of the Invention

[0028] The aspects and disclosures according to the present invention, in particular solid pharmaceutical composition comprises non-micronized imeglimin or pharmaceutically acceptable salts, vinylpyrrolidone polymer derivative and one or more pharmaceutically acceptable excipients.

[0029] In preferred embodiment, imeglimin or pharmaceutically acceptable salts thereof can be imeglimin hydrochloride.

[0030] In preferred embodiment amount of imeglimin hydrochloride can be between 75.0 - 98.0 % (w / w). Preferably, amount of imeglimin hydrochloride can be between 85.0 - 95.0 % (w / w).Excipients used in a formulation may adversely affect physicochemical and pharmacokinetic properties. These excipients can interact with the active ingredient. For this reason, while developing the formulation, the substances to be used in addition to the active substance must be carefully and consciously selected.

[0031] Lubricants are crucial excipients in pharmaceutical compositions, primarily used to reduce friction during the tablet manufacturing process. They help prevent the tablet blend from sticking to the equipment, ensuring a smooth and efficient production process. Lubricants improve the flow of the tablet mixture through the machinery, enhancing the uniformity and consistency of the final product. Additionally, they aid in the ejection of tablets from the die cavity, preventing damage and ensuring the integrity of the tablets.

[0032] Commonly used lubricants in pharmaceutical compositions include magnesium stearate, stearic acid, talc, sodium stearyl fumarate, colloidal silicon dioxide, and polyethylene glycol (PEG). In preferred embodiment in the present invention amount of lubricant can be between 0.1-3.5% (w / w). Preferably, amount of lubricant can be between 0.5 - 2.0 % (w / w)

[0033] In preferred embodiment in present invention lubricant can be sodium stearyl fumarate. In the preferred embodiment, the present invention amount of sodium stearyl fumarate can be between 0.1-3.5% (w / w). Preferably, the amount of sodium stearyl fumarate can be between 0.50 - 2.00 (w / w).

[0034] Commonly used binders in pharmaceutical compositions include polyvinylpyrrolidone (PVP), hydroxypropyl methylcellulose (HPMC), polyvinylpyrrolidone K12, polyvinylpyrrolidone K17, polyvinylpyrrolidone K25, polyvinylpyrrolidone K30, polyvinylpyrrolidone K90, polyvinylpyrrolidone-Vinyl acetate copolymer, crospovidone and starch.

[0042] In preferred embodiment pharmaceutical composition in present invention further comprise coating. Preferably, the amount of coating can be between 3.0 - 5.0 % (w / w).

[0043] The use of imeglimin or pharmaceutically acceptable salts thereof in very high amounts within a composition poses significant challenges in maintaining stability. Such elevated concentrations may lead to issues such as degradation of the active ingredient,undesirable interactions with excipients, or reduced shelf-life of the formulation. Addressing these stability concerns requires careful selection of excipients, optimization of formulation parameters, and the potential application of stabilizing agents or protective packaging systems.
