Definitions

  • the present invention relates to a stable transmucosal pharmaceutical composition of Levocetirizine or pharmaceutically acceptable salt thereof and and processes for preparing thereof.
  • This invention more particularly relates to the method of such composition for alleviating associated symptoms of the allergic diseases such as allergic rhinitis and urticaria requiring fast onset of action.
  • Allergic Rhinitis represents the most common chronic airway disease in the world affecting many individuals.
  • Symptoms include sneezing, runny nose and red, watery, itchy eyes and like which significantly impair the quality of life with the negative effects apparent in all areas of daily living; specifically difficulties with daily activities, reduced sleep quality, daytime fatigue, impaired learning, impaired cognitive functioning, decreased long time productivity, decreased feeling of mental wellbeing, so it impairs work productivity and school performance.
  • the AR can be considered to be a risk factor for the development of asthma and which is based on duration of symptoms of AR and their severity.
  • Urticaria is also known as hives and it is an outbreak of swollen, pale red bumps or plaques (wheals) on the skin that appear suddenly either as a result of the body's reaction to certain allergens, or for unknown reasons. Hives usually cause itching, but may also burn or sting. If the condition has a duration of less than 6 weeks, it is acute. If it persists for more than 6 weeks, or recurs, it is chronic. Angioedema is often associated with chronic urticaria. Symptoms of the disorder may endure for several months or years. The most frequent causes of acute urticaria, which may affect up to 15%— 25% of all individuals at some stage in their lives, are viral infections (especially affecting the upper respiratory tract), food allergies, and drug adverse reactions. Physical effects, systemic disease, or long-term infection may also lead to urticaria/angioedema.
  • Histamine has a key role in the pathophysiology of allergic inflammation. After exposure to an allergen, specific antibodies of the IgE type are produced in genetically predisposed individuals. Because of the central role of histamine in allergic responses, many allergic conditions are treated with antihistamines, including allergic rhinitis and urticaria.
  • Levocetirizine is the treatment of choice for the relief of symptoms of seasonal allergic rhinitis (SAR), perennial allergic rhinitis (PAR), and chronic idiopathic urticaria (CIU) in adults and children aged more than or equal to 6 years.
  • XYZAL Levocetirizine tablet
  • XYZAL Levocetirizine solution

  • the plasma half-life of oral tablet and oral solution in adult healthy subject is about 8 to 9 hours and the mean oral total body clearance for Levocetirizine is approximately 0.63 mL/kg/min.
  • Levocetirizine 5 mg in controlling pollen-induced symptoms has been observed at 1-hour post drug intake.
  • the extent of metabolism of Levocetirizine in humans is less than 14% of the dose. So there is 14% loss of drug because of liver metabolism.
  • Metabolic pathways include aromatic oxidation, N and O-dealkylation, and taurine conjugation. Dealkylation pathways are primarily mediated by CYP 3A4 while aromatic oxidation involves multiple and/or unidentified CYP isoforms.
  • US2006083786 relates to the taste masked pharmaceutical composition comprising Levocetirizine for the medical treatment of allergic conditions.

  • Levocetirizine dihydrochloride [(R)-[2-[4-[(4-chlorophenyl) phenylmethyl]-l- piperazinyl] ethoxy]] acetic acid dihydrochloride is an orally active Hl-receptor antagonist. It is the R enantiomer of cetirizine hydrochloride, a racemic compound with antihistaminic properties.
  • the empirical formula of levocetirizine dihydrochloride is C 21 H 25 ClN 2 0 3 ⁇ 2HCl.
  • the molecular weight is 461.82 and the chemical structure is shown below:
  • H-receptor histamine receptors
  • H1R Hl-receptor
  • histamine release has many clinical manifestations related to the numerous cells that can be involved in the allergic reaction, e.g., itch, pain, increase of the vascular permeability with edema and hypotension, flushing, headache, tachycardia, bronchoconstriction, reduction in the atrioventricular node conduction time, and impairment of the CNS functions. Additionally, histamine promotes the release of other mediators from immune-competent cells; it increases the cellular adhesion molecule expression, the chemotaxis of eosinophils and neutrophils, the antigen-presenting cell capacity, and other mechanisms of inflammation
  • Levocetirizine the active enantiomer of cetirizine, is an antihistamine; its principal effects are mediated via selective inhibition of HI receptors.
  • Levocetirizine shows a high affinity and a long-lasting occupancy of the H1R; therefore, the strong and sustained pharmacological inhibition of the H1R present on endothelial and vascular smooth muscle cells prevents vasodilatation, edema formation and mucus hypersecretion (Expert Opin. Pharmacother. (2009) 10(14)).
  • Levocetirizine has a potent and selective antihistamine activity. It has favourable pharmacodynamics and the pharmacokinetics characteristics e.g., high bioavailability and receptor occupancy, limited tissue distribution and a low degree of metabolism. In addition to the anti-histaminic activity, Levocetirizine also has the anti-inflammatory activity that are observed at clinically relevant concentrations and which may enhance its therapeutic benefit.
  • Levocetirizine has a half-life of 8-9 hours and oral total body clearance of about 0.63 mL/kg/min. Peak concentrations are typically 270 ng/ml and 308 ng/ml following a single and a repeated 5 mg O.D. dose, respectively. The onset of action of Levocetirizine 5 mg in controlling pollen-induced symptoms has been observed at 1-hour post drug intake. The extent of metabolism of Levocetirizine in humans is less than 14% of the dose.
  • the accumulation ratio following oral administration is 1.12 with steady state achieved after 2 days. Peak concentrations are typically 270 ng/ml ad 308 ng/ml following a single and a repeated 5 mg once daily dose respectively. Food had no effect on the extent of exposure (AUC) of the Levocetirizine tablet, but Tmax was delayed by about 1.25 hours and Cmax was decreased by about 36% after administration with a high fat meal. In adults, peak plasma concentrations are achieved 0.9 hour after administration of the oral tablet and it is achieved 0.5 hour after administration of oral solution.
  • Metabolic pathways include aromatic oxidation, N- and O -dealkylation, and taurine conjugation. Dealkylation pathways are primarily mediated by CYP3A4 while aromatic oxidation involves multiple and/or unidentified CYP isoforms. First pass metabolism greatly reduces the bioavailability of the drug.
  • Levocetirizine like Levocetirizine tablet and Levocetirizine solution (XYZAL) have Tmax longer than 0.5 hours which will lead to delay in onset of response. Delay in onset of action will eventually affects the on demand antiinflammatory responses required in many allergic conditions like Allergic Rhinitis, Urticaria and like.
  • the present invention provides transmucosal pharmaceutical compositions comprising Levocetirizine or pharmaceutically acceptable salt thereof in association with pharmaceutically acceptable excipients thereof characterised in that the composition of the present invention provides 80% drug release within 5 minute & thereby achieve Tmax at 0.25 to 0.5 hours.

  • Transmucosal refers to “the route of administration in which the drug is diffused through the mucous membrane. This can refer to inhalation, nasal, sublingual, vaginal, rectal, or ocular routes”.
  • Onset of action means “the time required after administration of a drug for a response to be observed.”
  • Onset of action refers to the duration of time it takes for a drug's effects to come to prominence upon administration. With oral administration, it typically ranges anywhere from 20 minutes to over an hour, depending on the drug in question. Other methods of ingestion such as smoking or injection can take as little as seconds to minutes to take effect.
