Release Profiles

Background: Tablets must be able to release the active drug in the gastrointestinal tract for absorption. The release profile of solid pharmaceutical dosage formulations can be quantified by assessing the disintegration and dissolution times tests. Binders are adhesives either from sugar or polymeric material that are added to tablet formulations to provide the cohesiveness required for the bonding together of the granules under compaction to form tablets.Objective: The objective of the study was to formulate and assess ibuprofen tablets using different concentrations of binders (Acacia and Gelatin).Methods: The granules were prepared using wet granulation method and analysed for flow properties based on USP/NF protocols. After granule compression, the tablets release profiles were thereafter assessed via the tablet dissolution and disintegration tests.Results: Weight variation, thickness and diameter were within the acceptable values for all batches indicative of a uniform flow. Batches with binder concentrations of 10 % and 20 % failed disintegration test due to a disintegration time above 15 min while the release rate for batches 1 and 4 was about 88 % in 60 min as against the other batches whose release rate was less than 50 % in 60 min as a result of increasing their binder concentrations.Conclusion: The study concluded that increasing the concentration of acacia and gelatin above 5% led to a decrease in percentage of drug released and an increase in disintegration time above 30 mins because 5% batches gave the best release profiles.

This study is aimed at evaluating the binding effect of Acacia etbaica gum in granule and tablet formulations using paracetamol as a model drug. Some physicochemical properties of the purified gum such as pH, the presence of tannin and dextrin, solubility, viscosity, loss on drying, total ash value, water solubility index, swelling power, moisture sorption, and powder flow properties were investigated. Paracetamol granules were prepared using wet granulation method at 2%, 4%, 6%, and 8% w / w of the Acacia etbaica gum and compared with granules prepared with reference binders (PVP K-30 and Acacia BP) in similar concentrations. The granules were characterized for bulk and tapped densities, compressibility index and Hausner ratio, angle of repose, flow rate, and friability. Finally, the prepared granules were compressed into tablets and evaluated for different tablet characteristics: weight uniformity, thickness, diameter, crushing strength, tensile strength, friability, disintegration time, and in vitro release profile. The physicochemical characterization revealed that tannins and dextrin are absent in the gum, and the gum has acidic pH. Both the moisture content and total ash values were within the official limits. Furthermore, the gum was found to be soluble in cold and hot water but insoluble in organic solvent and exhibited a shear thickening viscosity profile and excellent flow properties with excellent compressibility. The granules prepared with the gum of Acacia etbaica and reference binders showed good particle size distribution and excellent flow and compressibility properties. All the prepared tablets passed pharmacopeial specifications with respect to their uniformity of weight, thickness, and disintegration time. Tablets formulated with Acacia etbaica gum and acacia BP meet the compendial specification for friability at binder concentrations more than 2%. Drug release properties of all the batches formulated with Acacia etbaica, PVP, and acacia BP complied with the pharmacopeial specification. It can be concluded that the gum of Acacia etbaica could be explored as an alternative excipient for its binder effect in granule and tablet formulations.

The matrix tablets of cinnarizine and nimodipine were prepared with varying ratio of Carbopol- 971P and co-excipients of varying hydrophilicity (i.e. dicalcium phosphate and spray dried lactose) by direct compression and wet granulation using alcoholic mucilage. The prepared tablets were evaluated for weight variation, hardness and friability. The influence of concentration of the matrix forming material and co-excipients on the release rate of the drug was studied. The release rate of Cinnarizine (more soluble drug) from tablets followed diffusion controlled mechanism whereas for nimodipine (less soluble drug), the drug release followed case-II or super case- II transport mechanism based on Korsmeyer- Peppas equation. The results indicated that the drug release from matrix tablets was increases with increase in hydrophilicity of drug and co-excipients. The release of drug also increased with thermal treatment and decreasing polymer concentration.

In the present study we have formulated (F1 to F6) matrix tablets of atenolol and indapamide for the management of hypertension. As in simultaneous estimation of these drugs it was found that a confined release can be formulated. In the formulation of SR matrix tablet by using different concentration of delayed release agent DCP and pregelatinized starch as disintegrant we prepared tablets by wet granulation method. For sustained release action HPMC polymers were used for film coating. Preformulation studies were performed prior to compression. The compressed SR matrix tablets were evaluated for weight variation, hardness, friability, drug content, disintegration time and in vitro drug release using USP dissolution apparatus type 2 (paddle). It was found that the optimized formulation showed 49.33%, 48.90%, 48.52%, 47.65%, 46.84% and 46.51% release for atenolol in 12 hours respectively. However, indapamide released 49.62%, 49.39%, 48.72%, 48.27%, 47.59% and 47.36% at the end of 12 hr. The IR spectrum study revealed that there is no disturbance in the principal peaks of pure drugs atenolol and indapamide. This confirms the integrity of pure drugs and no incompatibility of them with excipients. The stability studies were carried out for the optimized batch for one months and it showed satisfactory results. The kinetic studies of the formulations revealed that diffusion is the predominant mechanism of drug and release follows Zero-order, Super case II transport.

Methods: TA seeds were steeped for 72 h, wet milled and the native Triticum aestivum starch (NTS) extracted. NTS (1kg) was oxidized by slurring in 4 L of 3.50% w/v sodium hypochlorite, washed to neutral pH with 95% v/v ethanol (MTS). MTS was dried at 60°C for 3 h, milled and classified (250 μm). The starches were characterized using standard methods and applied as binders at 1, 2 and 3% w/w in formulating metronidazole tablets using wet granulation. Methylcellulose and gelatin at similar concentrations were used as standards. Results: The granules and tablets were evaluated using standard methods. NTS and MTS had similar properties with starch. The modification improved the densities, hydration capacity and flow properties of MTS. The granules flowed and compressed well. The tablets had minimal weight variation, hardness (≥ 4 kgF), friability (<1%) and disintegration (<15 min). Metronidazole release (≥ 85%) within 60 min existed in all the batches except batches containing 1% methylcellulose and 3% gelatine. Conclusion: The results met with United States Pharmacopoeia specifications for oral uncoated metronidazole tablets. MTS performed better than NTS and compared well with methylcellulose and gelatin as binder in metronidazole tablet formulation.

Abstract Halal gelatin extracted from goatskin could be used as a new excipient in pharmaceutical dosage forms. This study was to determine the potency of gelatin extracted from goatskin as a binder on paracetamol tablets using wet granulation process with 2, 3 and 4% concentration ranges. As a comparison, tablets were formulated using bovine gelatin at the same concentration level. The results showed that weight variation, thickness uniformity and hardness value have met the requirements. Here, the paracetamol tablets using goatskin gelatin as a binder had better friability value, faster disintegration time and easier dissolution than the comparison (p < 0.05). Comparative test result showed increasing the concentration of gelatine caused the hardness value to go up, the disintegration time to take longer, and the tablet friability value to decrease (p < 0.05). The best tablets were produced with the 3% concentration of goatskin gelatine with the following evaluation results: the hardness value of 15.07 ± 0.67 Kp, the disintegration time of 3.71 ± 1.00 minutes and the friability value of 0.62% ± 0.89 respectively. The concentration of paracetamol in the 30th-minute dissolution test was equal to 99.78 ± 0.94%. The goatskin gelatin was very promising as a good binder using the wet granulation process.
