|6. |BRIEF RESUME OF THE INTENDED WORK: |
| | |
| |6.1 Need of Study: |
| |Oral drug delivery has been known for decades as the most widely utilized route of administration among all the routes that have been explored |
| |for the systemic delivery of different dosage forms. Proton-pump inhibitors (PPIs) have been very efficacious for the management of a variety of |
| |acid-related disorders such as dyspepsia, peptic ulcer, gastroesophageal reflux disease, laryngopharngeal reflux, Barrett’s esophagus, |
| |gastrinomas, Zollinger -Ellison syndrome. |
| |Proton pump inhibitors act by irreversibly blocking the H+/K+ adenosine triphosphatase enzyme system, more commonly known as gastric proton |
| |pump) of the gastric parietal cells. These drugs are absorbed into systemic circulation, diffuse into parietal cells of stomach and accumulate in|
| |the acid secretory canaliculi. Here proton activation takes place and tends to bind covalently with sulfhydryl groups of cysteine in H+/K+ |
| |ATPase, irreversibly inactivating the pump molecule. This provides a suppression of 24 to 48 hours as this is final step in gastric acid |
| |secretion1. |
| | |
| |Gastro resistant tablets(enteric coated) are used to resist the drug release in the gastric mucosa. These tablets remain intact in the stomach |
| |but quickly release in the upper intestine. The tablets are coated with polymers like cellulose acetate phthalate, polyvinyl acetate phthalate, |
| |hydroxypropylmethylcelluose phthalate. These polymers are esters, insoluble in gastric medium up to PH 4 and are intended to hydrate and begin |
| |dissolving as the tablet leaves the stomach, enter the duodenum(pH 5 to 6) and move furthur to small intestine where pH is 7to8 to release the |
| |drug. The primary mechanism by which these polymers lose their integrity, there by admitting intestinal fluid and releasing drug is ionization of|
| |the residual carboxylic groups on the chain and subsequent hydration. |
| | |
| |ADVANTAGES OF ENTERIC COATING DRUG DELIVERY SYSTEM |
| |To prevent irritation when directly exposed to gastric mucosa. e g aspirin |
| |To prevent degradation of acid labile drugs. |
| |Delivery of active pharmaceutical agents into intestine. |
| |To provide a delayed release component for repeat action tablet. |
| |To prevent nausea and vomitting when drugs are released in the stomach. |
| |To prevent the degradation of drugs at lower pH in the stomach. |
| |e g erythromycin2. |
| | |
| |Objective of Study: |
| |The aim of this work is development and evaluation of gastro |
| |resisitent tablet of proton pump inhibitor. |
| |In order to fulfill this aim we shall: |
| |Select the appropriate drug for the solid oral dosage form. |
| |Select excipients including polymers to develop the dosage form based on physico-chemical properties and compatibility of the Active |
| |Pharmaceutical Ingredient (API) and excipients. |
| |Preformulation studies on the API and excipients for the proposed formulations. |
| |Formulation of gastro resistant proton pump inhibitor tablets. |
| |In vitro evaluation of the formulations as per official & in-house protocols. |
| |Optimization of the dosage form based on evaluated parameters. |
| |Stability Study of the optimized formulation as per ICH guidelines. |
| | |
| |Review of Literature |
| |Anroop B Nair et al., studied the formulation and evaluation of enteric coated tablet of proton pump inhibitor for esomeprazole trihydrate with |
| |different polymers like Eudragit L-30 D-55, HPMC Phthalate, celluloseacetate Phthalate. The tablet showed good integrity, desirable for enteric |
| |coated tablets. Dissolution studies showed better dissolution for Methacrylic polymer than cellulose polymers3. |
| | |
| |A Mukharya et al., studied the Stable and Bioequivalent Formulation Development of Highly Acid Labile Proton Pump Inhibitor. The main challenge|
| |in the formulation of Rabeprazole tablets was the degradation of Rabeprazole upon exposure to acidic environment. Thus, to prevent exposure of |
| |Rabeprazole in gastric acidic environment enteric coating was done and to prevent interaction between Rabeprazole and acidic enteric coating |
| |material, seal coating was done over the core tablet. They have reported that the formulation did not release Rabeprazole in gastric acidic pH |
| |and released 91% of Rabeprazole in 45 minutes at intestinal alkaline pH4. |
| | |
| |Sindhu Abraham et al., studied the development and optimization of sublingual tablet of rabeprazole sodium, these were prepared by wet |
| |granulation process based on formulation variables including crospovidone and croscarmellose sodium. Optimization of tablet formulation showed |
| |short wetting time of 22 seconds and in vitro dispersion time 32 seconds6. |
| | |
| |UK medicines information pharmacists group studied the difference between the drugs like esomeprazole 40 mg, omeprazole 20 or 40 mg, |
| |pantoprazole 40 mg, lansoprazole 30 mg and rabeprazole 30 mg dosed once daily among 36 patients with gastro reflux disease symptoms. Studies |
| |showed that esomeprazole maintained intragastric pH levels at above 4 for longer periods than other drugs7. |
| | |
| |Hemanth Kumar Sharma et al., reported that Pantoprazole is a proton pump inhibitor prodrug used in the treatment of gastric ulcers and |
| |gastroesophageal disease. Pantoprazole must be absorbed in the gastrointestinal tract and because it is unstable under acidic conditions, enteric|
| |delivery systems are required. The purpose of this study was to prepare Pantoprazole loaded microbeads by ionotropic gelatin technique using |
| |sodium alginate and natural Mucoadhesive substance from the fruit of Dillenia indica followed by a coating with Eudragit L 100-55. The |
| |microspheres have been characterized in terms of their morphology, particle size, encapsulation efficiency, swelling ratio, mucoadhesivity and |
| |ability of stabilizing Pantoprazole in acidic media. Different formulation variables like polymer-polymer ratio, drug-polymer ratio and coating |
| |concentration were considered. Almost spherical microbeads were obtained with sufficient swelling, Mucoadhesive property and acid resistance. |
| |Dissolution study was followed at phosphate buffer (pH 7.4) for 8 hr8. |
| | |
| |Santhosh Kumar Jindal et al., formulated oral drug delivery device for insulin and to protect the sensitive drug from digestive enzymes and |
| |proteolytic degradation in stomach and upper part of gastro intestinal tract (GIT). So, for this purpose insulin enteric microspheres (EMS) were |
| |prepared using Hydroxy propyl methyl cellulose acetate succinate as enteric polymer, Bacitracin as protease inhibitor and Sodium oleate as |
| |absorption enhancer. In-vitro drug release studies determined that almost no drug was released in HCl (pH 1.2) for 2 hours and then maximum |
| |amount of drug was released within 70 minutes in Phosphate buffer (pH 7.4). In-vivo studies on male wistar rats confirmed a remarkable decrease |
| |in blood glucose level after 2 hours of administration of insulin EMS9. |
| | |
| |J Williams et al., In a randomised single blind crossover study in children with cystic fibrosis and pancreatic insufficiency, two enteric |
| |coated microsphere preparations of pancreatin were compared on a capsule for capsule basis, by measuring the coefficient of fat absorption, |
| |nitrogen excretion, weight change, and symptom scores after four weeks treatment with each preparation. Thirty nine subjects were randomly |
| |allocated to receive pancrease followed by Creon or vice versa. Each individual subject received the same number of capsules per day in each |
| |study period. Data from 27 children (Pancrease/Creon, n=13 and Creon/Pancrease, n=14) were suitable for analysis. Results showed no significant |
| |differences between the two preparations in any variable studied. We conclude that there is no significant difference between Pancrease and Creon|
| |when compared on a capsule for capsule basis10. |
| | |
| |S. Bozdag et al., prepared various coating solutions in different concentrations and applied to previously sub coated omeprazole tablets to |
| |examine whether this coating prevented omeprazole from degrading in acidic media.Dissolution tests were conducted in acidic and basic media to |
| |determine the appropriate coating ratio. For stability evaluation, an accelerated stability test was performed on developed tablet formulations |
| |and commercially obtained capsules. Samples were examined with regard to visual appearance, omeprazole content and dissolution properties for a |
| |month. For formulation consideration, the most promising results were obtained from HPMCP4 and CAP4 (4% enteric coating with hydroxypropyl methyl|
| |cellulose phthalate solution and cellulos acetate phthalate solution, respectively) sub coded preparations. From the stability aspect only Losec |
| |capsules (Astro-Turkey, commercial product) seem to be dependable11. |
| | |
| |Sumith Chakraborty et al., reported that Pantoprazole 5-(difluoromethoxy)- 2-[(3,4-dimethoxypyridin-2-yl) methylsulfinyl]- 3H-benzoimidazole is a|
| |proton pump inhibitor belongs to group of benzimidazole . This compound inhabits gastric acid formation and there by it is very efficient for the|
| |treatment of gastric and duodenum ulcers. In aqueous media more acidic than pH 4 it suffers a practically complete decomposition within a period |
| |shorter than 10 minutes. Even in solid state it is sensitive to heat, humidity, light and especially to substances containing an acidic group. |
| |Pantoprazole which have an irritant effect on the stomach, can be coated with a substance that will only dissolve in the small intestine. For |
| |such types of drugs, enteric coating added to the formulation tends to avoid the stomach's acidic exposure, delivering them instead to a basic pH|
| |environment (intestines pH 5.5 and above) where they do not degrade, and give their desired action. This stumulate us to formulate and evaluate |
| |pantoprazole as enteric coated tablet12. |
| | |
| |Rabia Bushra et al., reported that Ibuprofen is a propionic acid derivative that belongs to the class NSAIDs. Major adverse reactions associated |
| |with Ibuprofen are related to GIT and include peptic and mucosal ulcers, dyspepsia, severe gastric pain and bleeding, that results in excessive |
| |treatment failure. The goal of the study was to develop enteric coated Ibuprofen tablets in order to avoid gastric mucosal irritation, diffusion |
| |of drug across mucosal lining and to let active ingredient be absorbed easily in small intestine. The formulation was developed and manufactured |
| |through the direct compression process, the simplest, easiest and most economical method of manufacturing. Enteric coating was done using an |
| |Opadry white sub coating and an aqueous coating dispersion of Acryl-Eze. Enteric coated formulation was subjected to disintegration and |
| |dissolution tests by placing in 0.1 M hydrochloric acid for 2 h and then 1 h in phosphate buffer with a pH of 6.8. About 0.04% of drug was |
| |released in the acidic phase and 99.05% in the basic medium. These results reflect that ibuprofen can be successfully enteric coated in order to |
| |prevent its release in the stomach and facilitate rapid release of the drug in the duodenum, due to the presence of superdisintegrant. |
| |Formulating this enteric coated tablet could increase patient compliance by decreasing adverse drug reactions (ADRS) associated with Ibuprofen |
| |therapy13. |
| | |
| |A.R.Pohlmann., studied the gastro resistant microparticles containing sodium pantoprazole, stability studies and in vivo antiulcer activity. |
| |This loaded microparticles are prepared by spray drying in pilot scale using eudragit s 100 as polymer. Studies showed that microparticles had |
| |acceptable stability under accelerated condition and were efficient in protecting the stomach against ulceration caused by ethanol14. |
