MASTER OF PHARMACY IN PHARMACEUTICS 09/05/ 2011 “FORMULATION AND EVALUATION OF ORODISPERSIBLE TABLETS OF SALBUTAMOL SULPHATE” 2 6. SUMMARY OF THE INTENDED WORK 6.1 NEED FOR THE STUDY Oral route of drug administration is the most preferred route for administration of various drugs. Oral delivery is currently the gold standard in the pharmaceutical industry where it is regarded as the safest, most convenient and most economical method of drug delivery having the highest patient compliance. It is the most widely accepted, up to 5060% of total dosage form. Solid dosage forms are popular because of ease of administration, accurate dosage, self-medication, pain avoidance and most importantly the patient compliance. The most popular solid dosage forms being tablets and capsules; but for some patients the difficulty to swallow (dysphasia) is one of the important drawback of this dosage forms. Drinking water plays an important role in the swallowing of oral dosage forms. Often times people experience inconvenience in swallowing conventional dosage forms such as tablet when water is not available, in the case of the motion sickness (kinetosis) and sudden episodes of coughing during the common cold, allergic condition and bronchitis. For these reasons, tablets that can rapidly dissolve or disintegrate in the oral cavity have attracted a great deal of attention1. The concept of Orodispersible Tablets (ODTs) emerged with an objective to improve patient’s compliance. These dosage forms rapidly disintegrate and/or dissolve to release the drug as soon as they come in contact with saliva, thus obviating the need for water during administration, an attribute that makes them highly attractive for Paediatric and geriatric patients. Difficulty in swallowing conventional tablets and capsules is common among all age groups, especially in elderly and dysphagic patients2. Oro-dispersible tablets are not only indicated for people who have swallowing difficulties, but also are ideal for active people3. Orodispersible Tablets are also known as, mouth dissolving tablets, rapimelts, meltin-mouth tablets, fast disintegrating tablets and fast dissolving tablets. These are the solid unit dosage forms/entities containing medicinal substances which disintegrate or dissolve rapidly in oral cavity usually within a few seconds even without the need of water or chewing. As the tablet disintegrates in mouth, this can enhance the clinical effect of drug through pregastric absorption from the mouth, pharynx and oesophagus in such cases, bioavailability of drug is significantly enhanced by avoiding first pass hepatic metabolism than those observed with conventional tablets4. 3 United States Food and Drug Administration (FDA) define orally disintegrating tablets as “A solid dosage form which contain a medicinal substance or active ingredient which disintegrates rapidly within few seconds when placed on a tongue. US Food and Drug Administration Center for Drug Evaluation and Research (CDER) defines, in the ‘Orange Book’, an ODT as “a solid dosage form containing medicinal substances, which disintegrates rapidly, usually within a matter of seconds, when placed upon the tongue”. European Pharmacopoeia described orally disintegrating tablets as ‘uncoated tablets intended to be placed in the mouth where they disperse rapidly before being swallowed’ and as tablets which should disintegrate within 3 minutes5. About 35% of the general population in addition to 30-40% of elderly institutionalized patients and 18-22% of all persons in long term care facilities suffer from dysphagia, i.e. difficulty in swallowing6. One study showed that 26% out of 1576 patients experienced difficulty in swallowing tablets due to their large size, followed by their surface, shape and taste7. Recent market studies indicate that more than half of the patient population prefers ODTs to other dosage forms and most consumers would ask their doctors for ODTs (70%), purchase ODTs (70%), or prefer ODTs to regular tablets or liquids (>80%)8. Mainly ODTs are prepared by various techniques, such as direct compression, solid dispersion moulding, sublimation and by the use of super disintegrants such as crosspovidone, croscarmellose sodium, sodium starch glycolate. Of the above techniques, the simple one is direct compression, which is cost effective. The super disintegrants are added to this formulation to enhance the disintegration of tablet into smaller particles which provides rapid onset of action9. ODTs offer the luxury of much more accurate dosing than the primary alternative, oral liquids. This segment of formulation is especially designed for dysphagic, geriatric, pediatric, bed-ridden, travelling and psychotic patients who are unable to swallow or refuse to swallow conventional oral formulations10. Salbutamol sulphate is a selective β2-adrenergic agonist and represents an effective drug for the treatment of asthma and the symptomatic alleviation of bronchospasm. Asthma is a chronic inflammatory disease, which includes bronchial hyperactivity and bronchospasm characterized by hyper responsiveness of tracheo-brochial smooth muscle to variety of stimuli, resulting in narrowing of air tubes often accompanied by increased secretions and mucosal edema resulting in breathlessness or dyspnoea, wheezing cough, chest congestion and anxiety about being unable to breathe. It is a hydrophilic drug with a pKa of 9.2 and a log P value of 0.11. It is usually given by inhalation or slow intravenous injections, 4 in the management of severe asthmatic attacks. Actually, most (or all, in several countries) products containing this drug are administered by inhalation. The plasma half-life of the drug has been estimated to range from 4 to 6 hours, so the recommended dose in adults and children is usually given every 4 to 6 hours. Even when short-acting β2-adrenergic receptor agonist is given as an inhalation, it has been suggested that majority of the dose is swallowed and absorbed from the gut and intravenous injections are painful administration11,12,13. A fast dissolving tablet form would thus be advantageous and patient compliant, as salbutamol sulphate is water-soluble and its preparation into a fast dissolving form would render it to dissolve rapidly and thereby result in rapid absorption without any lag time. Hence an attempt was made for preparation of mouth dissolving tablet of salbutamol sulphate with an aim of reducing the lag time and providing faster onset of action to relieve the acute asthmatic effect immediately14. 6.2 OBJECTIVES OF THE STUDY To formulate and evaluate orodispersible tablets containing β2 receptor agonistsalbutamol sulphate for bronchial asthma and to investigate the effect of super disintegrants on the release profile of the drug from the tablets. Pre formulation studies including Complete characterization of the drug and polymers, and its analytical method development Screening of excipients for compatibility Selection of suitable technology for preparing fast dissolving tablets Formulation of fast dissolving tablets with different polymers and super disintegrants Evaluation of the physico-chemical characteristics of the prepared tablets like diameter, weight uniformity, hardness, content uniformity etc To assess the stability of the prepared formulations as per ICH guidelines 5 6.3 REVIEW OF LITERATURE Keny et al15., prepared mouth disintegrating tablets of rizatriptan benzoate using superdisintegrants crospovidone, carboxymethylcellulose calcium, Indion 414 and Indion 234 by direct compression method. The tablets prepared were evaluated for thickness, uniformity of weight, content uniformity, hardness, friability, wetting time, in vitro and in vivo disintegration time, mouth feel, in vitro drug release and assay by high performance liquid chromatography. The tablets disintegrated in vitro and in vivo within 4 to 7 s and 6 to 19 s, respectively. Almost 90% of drug was released from all formulations within 20 min. The drug release from the formulations followed first order kinetics. Stability studies of the tablets at 40±2 o /75%±5% RH for 1 mo showed non significant drug loss. The formulation containing combination of crospovidone and Indion 234 was found to give the best results. Apart from fulfilling all official and other specifications, the tablets exhibited higher rate of release. Senoy et al16., optimized the dissolving tablets of diclofenac sodium was developed by using direct compression after incorporating super disintegrants such as cross linked carboxy methyl cellulose, sodium starch glycolate and cross linked povidone in different concentrations and evaluated the effect of their concentrations on the characteristics of fast dissolving tablets mainly in terms of disintegration time and dissolution rate. Tablets containing cross linked carboxy methyl cellulose showed better disintegrating character along with rapid release. Ajaykumar Patil et al17., prepared mouth dissolving tablets of montelukast sodium by direct compression method using superdisintegrants such as croscarmellose sodium and crospovidone. The compatibility of the drug in the formulations was confirmed by IR studies. The formulations were subjected to precompression and postcompression parameters and the results were found to be within acceptable limits. The formulated tablets disintegrated in less than 26.33 sec fulfilling the official requirements for dispersible tablets. The rapid drug dissolution was observed in the formulations containing croscarmellose sodium and followed first order release kinetics. Finally, it can be concluded that mouth dissolving tablets of montelukast sodium can be prepared by direct compression method using croscarmellose sodium as superdisintegrant. Mahajan et al18., developed mouth dissolving tablets of sumatriptan succinate using super disintegrants like sodium starch glycolate, carboxy methyl cellulose, treated agar and microcrystalline cellulose and dissolve in saliva and swallowed without water. There is limited reference of work done about the use of ion exchange resins in oro dispersible tablets 6 for taste masking and rapid disintegration. Hence, it was planned to employ this technique for ambroxol hydrochloride, as the model drug. Patel et al19., developed fast dissolving tablets of etoricoxib. Granules containing etoricoxib, menthol, crospovidone, aspartame and mannitol were prepared by wet granulation technique. Menthol was sublimed from the granules by exposing the granules to vacuum. The porous granules were then compressed in to tablets. Alternatively, tablets were first prepared and later exposed to vacuum. The tablets were evaluated for percentage friability and disintegration time. A 32 full factorial design was applied to investigate the combined effect of 2 formulation variables: amount of menthol and crospovidone. The results of multiple regression analysis indicated that for obtaining fast dissolving tablets; optimum amount of menthol and higher percentage of crospovidone should be used. A surface response plots are also presented to graphically represent the effect of the independent variables on the percentage friability and disintegration time. The validity of a generated mathematical model was tested by preparing a checkpoint batch. Sublimation of menthol from tablets resulted in rapid disintegration as compared with the tablets prepared from granules that were exposed to vacuum. The optimized tablet formulation was compared with conventional marketed tablets for percentage drug dissolved in 30 min (Q 30 ) and dissolution efficiency after 30 min (DE 30 ). From the results, it was concluded that fast dissolving tablets with improved etoricoxib dissolution could be prepared by sublimation of tablets containing suitable subliming agent. Raghavendrarao et al20., developed rapidly disintegrating tablets carbamazepine, which is a bitter drug poor solubility in biological fluids is the major problem with this drug has also its poor bioavailability after oral administration. The rate of absorption or the extent of bioavailability for such a poor soluble drug is controlled by rate of dissolution in GIT fluids. Hence, to enhance the solubility of the drug a complex of carbamazepine was prepared with β-cyclodextrin and this complex was compressed into tablets. Gnanaprakash et al21,. prepared fast dissolving tablets of valdecoxib in the oral cavity with enhanced dissolution rate. The fast dissolving tablets of valdecoxib was prepared with some carriers (polymers) and super disintegrants such as polyvinyl pyrrolidone (PVP), sodium carboxy methyl cellulose (SCMC), crospovidone NF and β – cyclodextrin. The above mentioned all carriers and superdisintegrants were taken in different proportions of 5, 10, and 15%. All the formulations of the fast dissolving tablets of valdecoxib were prepared by direct compression technique. The blend was examined for angle of repose, bulk density, compressibility index and Hausner’s ratio. The prepared tablets were evaluated for hardness, drug content uniformity, friability, disintegration time and dissolution rate. The prepared formulations drug release was found to be comparable with the marketed dispersible tablets. 7 Gohel et al22., developed mouth dissolving tablets of nimesulide. Granules containing nimesulide, camphor, crospovidone and lactose were prepared by wet granulation technique. Camphor was sublimed from the dried granules by exposure to vacuum. The porous granules were then compressed. Alternatively, tablets were first prepared and later exposed to vacuum. The tablets were evaluated for percentage friability, wetting time, and disintegration time. In the investigation, a 32 full factorial design was used to investigate the joint influence of 2 formulation variables: amount of camphor and crospovidone. The results of multiple linear regression analysis revealed that for obtaining a rapidly disintegrating dosage form, tablets should be prepared using an optimum concentration of camphor and a higher percentage of crospovidone. A contour plot is also presented to graphically represent the effect of the independent variables on the disintegration time and percentage friability. A checkpoint batch was also prepared to prove the validity of the evolved mathematical model. Sublimation of camphor from tablets resulted in superior tablets as compared with the tablets prepared from granules that were exposed to vacuum. The systematic formulation approach helped in understanding the effect of formulation processing variables. Shirsand et al23., prepared fast dissolving tablets of clonazepam by direct compression method with a view to enhance patient compliance. A 32 full factorial design was applied to investigate the combined effect of two formulation variables: amount of crospovidone and microcrystalline cellulose. Crospovidone (2-8% w/w) was used as superdisintegrant and microcrystalline cellulose (20-40% w/w) was used as diluent, along with directly compressible mannitol to enhance mouth feel. The tablets were evaluated for hardness, friability, thickness, drug content uniformity, in vitro dispersion time, wetting time and water absorption ratio. Based on in vitro dispersion time (approximately 16 s); the formulation containing 2% w/w crospovidone and 40% w/w microcrystalline cellulose was found to be promising and tested for in vitro drug release pattern (in pH 6.8 phosphate buffer). Short-term stability (at 40 degrees /75% relative humidity for 3 mo) and drug-excipient interaction. The optimized tablet formulation was compared with conventional commercial tablet formulation for drug release profiles. This formulation showed nearly five-fold faster drug release (t(50%) 3.5 min) compared to the conventional commercial tablet formulation (t(50%) 16.4 min). Short-term stability studies on the formulation indicated that there are no significant changes in drug content and in vitro dispersion time (P<0.05). Narmada et al24., formulated fast dissolving tablet of amlodipine besylate for rapid action by 3 sublimation method using a 2 full factorial design. FT-IR and D.T.A studies revealed that there was no physico-chemical interaction between amlodipine besylate and other excipients. All formulations are evaluated for pre-compression and post-compression parameters, 8 wetting time, water absorption ratio. The results obtained showed that the quantity of starch potato, sodium starch glycolate, camphor significantly affect response variables. The results indicate that the optimized tablet formulation provides a short DT of 8 sec with sufficient crushing strength and acceptable friability. Stability studies of optimized formulation revealed that formulation is stable. Bhupendra et al25., formulated directly compressible orally disintegrating tablets of cinnarizine with sufficient mechanical integrity, content uniformity, and acceptable palatability to assist patients of any age group for easy administration. Effect of varying concentrations of different superdisintegrants such as crospovidone, croscarmellose sodium, and sodium starch glycolate on disintegration time was studied. Absorption ratio (R) for each of three superdisintegrants at concentrations studied. Considering the ‘R’ values and disintegration time, crospovidone was significantly superior compared to other two superdisintegrants tested. Release of drug was faster from formulations containing 6% crospovidone (CP5) compared to the marketed convetional cinnarizine tablet. Finally concluded that directly compressible orally disintegrating tablets of cinnarizine with lower friability, acceptable taste, and shorter disintegration times were obtained using crospovidone at optimized concentrations. Ganesh kumar et al26., studied about the fast dissolving tablets of chlorpromazine Hcl in the oral cavity with enhanced dissolution rate. The tablets were prepared with five superdisintegrants eg: Sodium starch glycolate, crospovidone, croscarmellose, L-HPC, pregelatinised starch, The blend was examined for angle of repose, bulk density, tapped density, compressibility index and Hausners ratio. The tablets were evaluated, It was concluded that the fast dissolving tablets with proper hardness, rapidly disintegrating with enhanced dissolution can be made using selected superdisintegrants. Shailendra Kumar et al27., prepared fast disintegrating combination tablets of omeprazole and domperidone by using pertinent disintegrant. using mannitol as diluent and sodium saccharin as sweetening agent along with three different levels of disintegrant. The superdisintegrant used in this study were kollidon CL, Ac-Di-Sol and SSG. The tablets were evaluated. Using the same excipients, the tablets were prepared by direct compression and were evaluated in the similar way. Drug content was estimated by using HPLC method and also assay of sample was compared with standard drugs (omeprazole and domperidone). Omeprazole and domperidone were well resolved and the retention times were around 9.01 and 6.2 respectively. From the results obtained, it can be concluded that the tablet formulation prepared with 4.76% Ac-Di-Sol (internally cross linked form of sodium carboxymethylcellulose) ie. 10 mg showed disintegration time of 15 seconds in vitro. 9 Nagendrakumar et al28., prepared fast dissolving tablets of fexofenadine Hcl by effervescent method with a view to enhance patient compliance. Three super-disintegrants viz., crospovidone, croscarmellose sodium and sodium starch glycolate along with sodium bicarbonate and anhydrous citric acid in different ratios were used and directly compressible mannitol (Pearlitol SD 200) to enhance mouth feel. The prepared batches of tablets were evaluated for hardness, friability, drug content uniformity and in vitro dispersion time. Based on the in vitro dispersion time (approximately 20 s), three formulations were tested for in vitro drug release pattern in pH 6.8 phosphate buffer, short-term stability at 40 degrees /75% RH for 3 mo and drug-excipient interaction (IR spectroscopy). Among the three promising formulations, the formulation ECP(3) containing 8% w/w of crospovidone and mixture of 24% w/w sodium bicarbonate 18% w/w of anhydrous citric acid emerged as the best (t(50%) 4 min) based on the in vitro drug release characteristics compared to conventional commercial tablet formulation (t(50%) 15 min). Short-term stability studies on the formulations indicated that there are no significant changes in drug content and in vitro dispersion time (P<0.05). 7.
