ENCLOSURE-I

6) Brief resume of the intended work:

6.1) Need for the study:

Tonsillitis is an inflammation of the tonsils, the fleshy clusters of tissue on both sides of the back of the throat. The tonsils become enlarged and have a yellow or white coating. Pharyngitis is an inflammation caused by swelling of the pharynx between the tonsils and the voice box(larynx).1

Oral route is the most important and preferable route of administration for solid dosage forms. Tablets are the most common solid dosage forms, administered orally. Fast dissolving tablets are disintegrating and/or dissolve rapidly in saliva without the need for water. Fast dissolving tablets were formulated for pediatric, geriatric and bedridden patients.2

Cefixime is an antibiotic drug and belongs to third generation cephalosporin.It is highly stable in the presence of beta-lactamase enzymes. As a result, many organisms resistant to penicillin’s and some cephalosporins due to the presence of beta-lactamases may be susceptible to cefixime. It has molecular weight of 453.45gms/mol and chemical formula C16H15N5O7S2, IUPAC name (6R, 7R)-7-[(2z)-2-(2-amino-1,3-thiazol-4-yl)-2-[(carboxymethoxy)imino]acetamido]-3-ethenyl-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid. It has a half life of four hours.3

The fast dissolving tablets will enhance the clinical effect of the drug through pre gastric absorption from the mouth, pharynx and oesophagus by avoiding first pass metabolism. The fast dissolving tablets are formulated for many elderly persons who have difficulties in taking conventional oral dosage forms because of hand tremors and dysphagia.4

The objective and aim of the current study is to formulate and develop fast dissolving tablets of cefixime,in-vitro evaluation of formulated tablets,and to minimize the disintegration time by using superdisintegrants.

6.2) Review of literature:

SatyanarayanaTet al., formulated and evaluated cefixime trihydrate oral disintegrating tablet’s using different concentrations of super disintegrating agents like croscarmellose sodium, sodium starch glycolate. Tablets were prepared by direct compression method. Oral disintegrating tablets had emerged as an alternative to the conventional oral dosage forms to improve the patient compliance. As the paediatric and geriatric patients had complained about the swallowing of conventional oral solid dosage forms, it became necessary to develop a dosage form which is patient friendly.5

Raghavendra rao NG et al., developed novel co-processed superdisintegrants by solvent evaporation method by using crospovidone and starch glycolate in different ratios (1:1, 1:2, and 1:3) for use in the fast dissolving tablet formulations. Fast dissolving tablets of felodipine were prepared by using the above co-processed superdisintegrants and evaluated for pre-compression and post-compression parameters. Effect of co-processed superdisintegrants on wetting time, disintegrating time, drug content, in-vitro release have been studied. It was concluded that dissolution rate of felodipine could be enhanced by coating the tablets with co-processed superdisintegrants.6

Raghavendra rao NGet al. designed fast dissolving tablets of nimodipine by direct compression technique with β-cyclodextrin complexes using various superdisintegrants. The powder blends were subjected for post-compression parameters. The prepared tablets were characterized by Digital scanning colourimetry (DSC) and FTIR studies. No chemical interaction between drug and excepients was confirmed by DSC and FTIR studies. The values of pre-compression parameters evaluated were within prescribed limits and indicated good free flowing property.7

Basawaraj patil Set al., designed and developed fast dissolving tablets of tizanidine hydro chloride by direct compression method. Formulations were evaluated for pre-compressional parameters as well as post-compressional parameters. The prepared tablets were characterized by FTIR studies. It was concluded that FDT could be prepared by direct compression method using different superdisintegrants enhanced dissolution will lead to improved bioavailability, improved effectiveness of tizanidine hydrochloride.8

Peter Cet al., designed fast dispersibleibuprofen tablets which disintegrate either rapidly in water, to form a stabilized suspension, or disperse instantaneously in the mouth to be swallowed without the aid of water. A direct compression method was used to prepare these two types of tablets containing coated Ibuprofen as a high dosed model drug. The selected tablet formulation, containing 26% galactomannan and 5% crospovidone, initiated disintegration before the galactomannan begun to swell. These tablets disperse in water with in 40 s and show a crushing strength of 95N.9

Birajuet al., investigated and developed the fast dissolving tablets of glipizide by direct compression method with a view to enhance patient compliance. Many patients expressed difficulty in swallowing tablets and hard gelatin capsules, resulting in non-compliance and ineffective therapy. Recent advances in novel drug delivery systems aimed to enhance safety and efficacy of drug molecules by formulating a convenient dosage form for administration and to achieve better patient compliance. One such approach led to development of fast dissolving tablet.10

Shaileshet al., investigated to optimize and formulate promethazine theoclate fast dissolving tablets that offer a suitable approach to the treatment of nausea and vomiting. The solubility of theoclate was increased by formulating it as a fast dissolving tablet containing β-cyclodextrin, crospovidone and camphor, using direct compression method. The optimization study involved multiple regression analysis and revealed that optimum amounts of camphor, crospovidone and β-cyclodextrin gave a rapidly disintegrating/dissolving tablet.11

Bhavesh Jet al., designed fast disintegrating tablet of diclofenac sodium. It was extensively used asan Non steroidal anti inflammatory drugs (NSAIDS); employed in the treatment of rheumatoid arthritis and osteoarthritis, affords quick relief of pain and wound oedema. Conventional tablet and hard gelatin capsule dosage forms posses higher disintegration time so patients obtain pharmacological effect after 30 to 45 minutes of dosage form administration that may result in high incidence of patient compliance and variable bioavailability. Fast disintegrating tablets were gaining prominence as new drug delivery systems. These dosage forms had shown disintegration within a minute with very less quantity of water.12

Tejviret al., aimed at novel drug delivery systems, tablets were most widely accepted dosage forms. Yet, dysphagiawas the most common disadvantage of conventional tablets. This was seen to afflict nearly 35% of the general population, to overcome such problems, certain innovative drug delivery systems, like ‘mouth dissolving tablets’ (MDT) have been developed. These are novel dosage forms which dissolved in saliva within few seconds, when placed on tongue. Such MDT’s could be administered without the need of water and are thus quite suitable for children, elderly and mentally disabled patients.13

Katsuhideet al., prepared a rapidly disintegrating tablets containing glycine and carboxymethylcellulose. Effect of disintegrant on the disintegration behaviour of the tablet in the oral cavity was evaluated. Wetting time of tablet prepared from carboxymethylcellulose having the hardness of 4 kg was 3 s. Tablet containing NS-300 showed fastest disintegration compared to other formulations.These results suggested that NS-300 possessed excellent wetting nature and resulted in the rapid disintegration of tablet. It was suggested that the tablet formulation containing NS-300 and glycine was highly applicable to water-insoluble drug, such as ethenzamide.14
