Effervescent Tablet

The purpose of this study was to determine the physical properties of probiotic effervescent tablets with two different coatings that are tapioca and maltodextrin to improve water quality in shrimp farming ponds. This study used probiotics to improve the environmental quality of shrimp pond waters. Liquid probiotics from Research Institute for Coastal Aquaculture in Maros, South Sulawesi that contain Brevibacillus laterosporus. Probiotics that have been used are liquid and difficult to transport, therefore microencapsulation is carried out on liquid probiotics aimed at facilitating their distribution. The use of microencapsulating materials is to entrap or immobilize probiotic bacteria within microcapsule and to protect the bacteria during the drying process. Effervescent tablets were prepared in a dosage of 800 mg by wet granulation methods. This experiment was replicated 3 times. Tablets were evaluated for their physical properties there are mean weight, friability, hardness, disintegration time and pH. The results showed that mean weight for effervescent tablets with maltodextrin coatings was 796 mg, had a friability value 0.09%, a hardness value of 13.7 N and disintegration time of 10.68 minutes. Both probiotic effervescent tablets meet the standards pH of 7.07 and 6.67. The maltodextrin coatings was the best treatment of this study.

Effervescent Tablet

Abstract RICA (Research Institute for Coastal Aquaculture) Maros in South Sulawesi has developed 5 probiotic preparations, namely RICA-1, RICA-2, Rica-3, RICA-4 and RICA-5 in liquid form to improve shrimp farming in ponds. In practice, the use of liquid probiotics has been very optimal but the distribution is constrained because of its liquid form. For this reason, microencapsulation of liquid probiotics is carried out to protect from the external environment and maintain the viability of probiotic cells in the encapsulated matrix. The purpose of this study was to determine the physical properties of probiotic effervescent tablets using tapioca coating with different concentration variants (10 and 20%) with four effervescent tablet formulas. The results showed that the pH of the probiotic effervescent tablet Formula 3 with a coating concentration of 10% tapioca had a neutral pH compared to all existing formulas. However, the pH for probiotic effervescent tablets produced by all formulas can still be applied to shrimp ponds. Formula 4 with 10% tapioca coating has a mean weight and hardness that is close to the standard as well as a disintegration time that meets the specified standard of tablet physical properties. Meanwhile, the tablet friability value was met by Formula 3 with a concentration of 10% tapioca coating. It can be concluded that the best formula that meets the standard physical properties of tablets is Formula 4 with 10% tapioca coating. The probiotic effervescent tablet with tapioca coating has a weakness in the hardness value which causes the average weight to be not uniform. These results indicate that tapioca coating is not suitable for use as a coating for probiotic effervescent tablets.

The drying process of corn noodles was an effort to increase the shelf life and it was a form of noodles diversification. The objective of this research was to study and analyze the effect of guar gum addition on the physical quality of the extruded dry corn noodle made from a mixture of wet and dry corn flour. Manufacturing dry corn noodles was conducted using wet corn noodles from a mixture of wet and dry corn flour, which was then dried in a tray dryer at a temperature of 60-70 °C for 1 - 1.5 hours. The treatments used were a combination of alum levels of 0.01%; moisture content of 80% (dry base); and guar gum concentration of 0%, 1%, and 2%. Physical properties of dry corn noodles included rehydration time, hardness, adhesiveness, suppleness, elongation, and cooking loss. The results showed that the optimum rehydration time for dry corn noodles was about 9 minutes. The addition of guar gum to the physical qualities of dry corn noodles tended not to be significant statistically, but as a score, an increase in guar gum levels tended to increase the elongation of dry corn noodles. While, increasing levels of guar gum tended to reduce the stickiness and cooking loss levels of them.

Microcrystalline cellulose was isolated from rami (Boehmeria Nivea L. Gaud), and applied as disintegrant in tablets of dimenhydrinate, made by direct compression and wet granulation. The aim of this study is to produce dimenhydrinate tablets with Microcrystalline Cellulose Rami (MCC Rami) isolated from Rami (Boehmeria Nivea L. Gaud), as a disintegrant and assess the effect of MCC Rami and Granulation technique on physical properties of drug such as, disintegration time, drug release and dissolution. Formulations of dimenhydrinate 100mg tablets were prepared with a combination of mannitol and lactose as a filler and MCC Rami as disintegrant in a concentration of 10-20%. The formulas were directly compressed or were compressed into tablets after wet granulation. The mechanical properties, drug release, physical properties and effects of process parameters, methods of applying disintegrant in tablet formulas were examined. A significant difference in disintegration time of tablets that were produced by direct compression and wet granulation was seen, that can be attributed to the porous structure of granules that enhanced fast disintegration, which had eventually improved dissolution and drug release. F1 and F2 with MCC Rami and physical mixture of MCC Rami with crosspovidone as a disintegrant that were directly compressed disintegrated in 79 and 72 seconds respectively thats not a significant difference, however when MCC was applied in an intragranular way its disintegration time is 67 seconds. The results showed that the method of disintegrant application and press of tableting has a significant effect on drug release and dissolution.Keywords : Microcrystalline Cellulose, wet granulation, disintegrant, Boehmeria Nivea L.

Candesartan cilexetil is a group of selective AT1 hypertension drugs (angiotensin II receptor antagonist 1). The drawback of candesartan cilexetil in conventional tablets is that it cannot be used for geriatric patients who have difficulty swallowing tablets, patients with developmental disorders of the muscle and nervous system (tremors), and in schizophrenic patients that lead to poor patient compliance, so to overcome this problem alternative dosage forms are made new namely ODT candesartan cilexetil. This study aims to determine the effect of the combination of superdesintegrant croscarmellose sodium and crospovidone on the quality test of the physical properties of tablets. Candesartan cilexetil ODT tablets bolted by direct compression method with variations in levels of superdesintegrant croscarmellose sodium and crospovidone 2: 3,5%, 2,75: 2,75%, 5: 0,5%, 4,25: 1,25 %, 3,5: 2%. Tests conducted to determine the physical quality of candesartan cilexetil ODT, namely organoleptic, weight uniformity, size uniformity, hardness, brittleness, disintegration time, wetting time and water absorption ratio. Showed an increase in the use of crospovidone (5%) and a decrease in croscarmellose sodium (0.5%) had a greater effect on the disintegration time because it could make the tablet porous when in contact with water so that it would accelerate the disintegration time of 29.167 seconds and increase the speed of wetting the tablets 25.33 seconds. The combination of superdisintegrant croscarmellose sodium and crospovidone (0.5: 5%) in formula 3 can provide physical properties that meet the best quality ODT requirements for candesartan cilexetil.
