Definitions

  • the present invention relates to water soluble pharmaceutical compositions comprising acarbose and use of these compositions in diabetes, adiposity and hyperlipoidemia.
  • Diabetes is a chronic disease which is characterized by insufficient or lack of insulin production by the pancreas and leads to disorders of carbohydrate, lipid and protein metabolism. There are two major types of diabetes.
  • Type I diabetes grows because beta cells in the pancreas can produce very little or no insulin associated with autoimmune mechanisms. Insulin is a hormone which is responsible for reducing elevated blood sugar. Blood sugar level rises depending on reduction in amount or in efficiency of insulin (hyperglycemia). Type I diabetes generally develops in children or young adults. Type II diabetes is the most common type of diabetes and characterized by insulin resistance. In this type of diabetes, insulin is released properly but it cannot be sufficiently effective.
  • the primary treatment method for diabetic patients is diet and exercise. This treatment approach provides very little weight loss but regulates insulin sensitivity. Sometimes, it can be possible to control blood sugar level for a long period of time only with this treatment method. However, the tendency towards insulin resistance in these people never disappears; therefore, the diet, exercise and weight control should be maintained continuously. In the cases that diet and exercise are insufficient, the second step of the treatment is oral anti-diabetic drugs and insulin reinforcement.
  • the main oral anti-diabetics used in treatment of Type II diabetes are sulfonylureas, biguanides and alpha glucosidase inhibitors,
  • Acarbose which is an alpha glucosidase inhibitor was first disclosed in the patent document numbered DE2347782.
  • Acarbose is produced by fermentation of the microorganism called Actinoplanes utahensis.
  • Acarbose inhibits alpha glucosidase enzyme which is responsible for digestion of carbohydrates in lumen of the small intestine. Digestion and absorption of carbohydrates in the intestine are slowed down by inhibition of this enzyme; therefore elevation in blood sugar level after meals is prevented. Acarbose does not affect insulin release from the pancreas, insulin use in the tissues or glucose outflow from the liver. Therefore, acarbose does not cause hypoglycaemia when used singly.
  • acarbose can be preferred as a primary treatment in the case that there is diabetes that cannot be controlled by diet or it can be preferred as combination treatment option in the case that postprandial hyperglycemias cannot be prevented during the treatments of sulfonurea, biguanide or insulin.
  • the formulation comprising the active agent acarbose is marketed under the trade name Glucobay® in the form of 50 and 100 mg tablets.
  • solid dosage forms such as tablet cause difficulty of use generally in geriatric, pediatric and disabled patients who have swallowing difficulty. Feeling of obstruction and choking can o uf ⁇ rr3 ⁇ 4drviduals due to the ⁇ rob1 ⁇ 2n ⁇ e €umng- & pharyngeal and esophageal motility and consequently taking drug can be disgustful and painful for patients. In line with this, the patient delays drug intake and this situation decreases efficiency of the treatment significantly and affects life quality of the patient.
  • dosage forms which comprise the active agent acarbose and are easy-to-use for patients in order to be used in treatment of diabetes, adiposis and hyperlipidemia.
  • Suspension forms which are presented as an alternative in order to overcome the problems caused by solid dosage forms cannot be performed in most of the active agents due to the reasons that suspension forms have the possibility of causing high and/or uncontrolled dose intake and furthermore there is problems in physical and chemical stabilities of suspension forms after diluted; production costs of suspension forms are high and they pose problem in using and carrying.
  • acarbose is a hygroscopic molecule; therefore, it is quite hard to formulate acarbose in water soluble dosage forms such as suspension. Contact of the active agent with water leads to disintegration of the formulations in a shorter time than expected and quickly.
  • the present invention relates to water soluble dosage forms comprising the active agent acarbose; the methods for preparing these dosage forms and usage areas thereof.
  • Formulating the formulations of the present invention in water soluble dosage forms have enabled that required therapeutic benefit is provided by using less amount of active agent than the active agent amount comprised in the dosage forms in the prior art. Use of less active agent is also advantageous for the reason that it reduces side effect possibility that can be caused by the formulations.
  • one water soluble iOrmulations of the present invention is that the formulations comprise acarbose in the range of 1 % to 10 % by weight, preferably in the range of 1% to 9 % by weight, more preferably in the range of 1% to 8% by weight.
  • Another characteristic feature of the water soluble formulations of the present invention is that the formulations comprise acarbose in the range of 10-300 mg, preferably in the range of 20-200 mg, more preferably in the range of 50-150 mg.
  • one characteristic feature of the water soluble formulations of the present invention is that the formulations are formulated in the form of powder, granule, pellet, micro tablet or tablet.
  • the water soluble formulations of the present invention can comprise at least one pharmaceutically acceptable excipient selected from a group comprising effervescent couple, binder, lubricant, glidant, diluent, disintegrant, flavouring agent, sweetener, colouring agent, surfactant, antifoaming agent, viscosity agent, stabilizing agent, humectant or combinations thereof in addition to the active agent.
  • a pharmaceutically acceptable excipient selected from a group comprising effervescent couple, binder, lubricant, glidant, diluent, disintegrant, flavouring agent, sweetener, colouring agent, surfactant, antifoaming agent, viscosity agent, stabilizing agent, humectant or combinations thereof in addition to the active agent.
