Abstract

Cocrystal is a relatively new solid form of activepharmaceutical ingredient that offers an alternativeplatform in improving physicochemical properties ofactive pharmaceutical ingredients Padrela et al.,2009; Mashhadi et al., 2004. Cocrystal is defined asa stoichiometric multi-component system connectedby non-covalent interactions where all thecomponents neutral and solid under ambientconditions Thakuria et al., 2013. Cocrystal can beconstructed through interaction hydrogen bonding,pi-stacking, and van der Waals forces  Mashhadi etal., 2004. A pharmaceutical cocrystal is composed ofan API and an appropriate coformer as carboxylicacids and amides Qiao et al., 2011.Cocrystallization of active pharmaceutical ingredientis an opportunity for enhancement of importantphysiochemical properties of an activepharmaceutical ingredient without changing itsmolecular structure Maeno et al., 2014.Atorvastatin Calcium (AC), ([(R-(R*,R*)]-2-(4-fluorophenyl)-beta, delta-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid), calcium salt (2:1)trihydrate ([C33H34FN2O5]2Ca.3H2O), is considered asone of the most effective of synthetic lipid loweringagent Shete et al., 2010. The drug is orally used toreduce of total cholesterol, low density lipoproteinand triglycerides Anwar et al., 2011. There are 42crystalline structures of AC Shayanfar et al., 2013.However, chance to create AC into another crystalstructure to improving physicochemical properties ofAC is still fully open Chadha et al., 2012.In the present study, we explored cocrystallization ofAC by solvent evaporation method. This study aimedto confirm whether AC was able to form cocrystalwith malonic acid (MA) as coformer. AC-MAcocrystal was prepared by solvent evaporationmethod by using methanol as solvent.Characterization of cocrystal was done by powder Xraydiffractometry (PXRD), differential scanningcalorimetry (DSC), fourier transform infrared (FTIR)spectroscopy and scanning electron microscopy(SEM).

Abstract

Sappan wood (Caesalpinia sappan L.) was reported to have natural antioxidant properties. Brazillin is the compound responsible for its antioxidant effect. Antioxidants are needed to prevent premature aging of the skin. Essence is a cosmetic that contains topical antioxidants. Essence has advantages over other skincare products, and essence is easier to absorb into the skin. The objective of the present study was to optimize and evaluate the Essence of sappan wood ethanolic extract for treatment as a cosmetic antioxidant. Simplex lattice design was adopted to evaluate the effect of butylene glycol and glycerin concentration on Essence characteristics. The method used in the extraction is maceration with ethanol solvent. The results showed that both butylene glycol and glycerin significantly enhanced the viscosity and pH value of the sappan essence formulation. The optimum Essence formula consisted of 10% butylene glycol with a predicted viscosity value of 2,944 dPas and a pH of 5,075. The characteristics of the optimum formula of sappan wood extract Essence have a thick texture, a characteristic odor of colored extract brownish yellow, homogeneous, and has a spreadabillity of 14 cm.

Abstract

ABSTRACT Difficulty in swallowing drug and slow onset of action of drug are common problems of conventional tablet. Orally disintegrating tablet (ODT) is an innovative dosage form to overcome the problem of swallowing drug and provide quick onset of action of drug because it can disintegrates quickly when contact with saliva in less than 3 minutes. This study formulate and evaluate ODT containing salbutamol sulphate to relieve the respiratory disorders immediately. Materials that affect the disintegration time of ODT are superdisintegrants and binders. Sodium Starch Glycolate (SSG) is a superdisintegrant that has high swelling capacity and its efficiency is not affected by compression and hydrophobic materials. PVP K-30 is a water soluble binder that effective to increase hardness and decrease friability of ODT without prolonging the disintegration time. The aim of this study is to optimize SSG and PVP K-30 to get the optimum formula of ODT salbutamol sulphate. ODT salbutamol sulphate was made by direct compression method. The optimization was carried out using two-level and two-factor of factorial design. Disintegration time, hardness, and friability of ODT were responses that evaluated to get the optimum formula of ODT salbutamol sulphate. The result showed that SSG affected in increasing of disintegration time of ODT. PVP K-30 affected in increasing of disintegration time, decreasing friability, and increasing hardness of ODT. The optimum formula contained 4% of SSG and 1,5% of PVP K-30 resulted in 37,58 seconds of disintegration time, 4,713 kg/cm2 of hardness, and 0,6298% of friability. The optimum formula dissolved 92.296 % after 30 minute. Keywords : Orally disintegrating tablet; salbutamol sulphate; SSG; PVP K-30

Abstract

Ibuprofen is a pharmaceutical active compound used to treat mild to moderate pain and fever. However, ibuprofen has low solubility in water. One method to increase solubility is cocrystal formation. The ibuprofen cocrystal was prepared in this study using caffeine as a coformer at a 1:1 molar ratio via solvent evaporation and slurry methods. The results of the XRD and thermal analysis of the sample indicate that a new solid phase is formed in the specific sa mple, which is different from both of its constituent components. Morphologically, the resulting cocrystals show a change in shape from their constituent compounds as well as a change in size. The solubility test results show that cocrystal formation is able to increase the solubility of ibuprofen. The conclusion of this study is that ibuprofen cocrystals can be formed with the coformer caffeine at a molar ratio of 1:1 using the slurry method and solvent evaporation.
