Ketoprofen is a propionic acid derivative that has anti-inflammatory, analgesic, and antipyretic activity. Transdermal patch dosage form is the right choice for ketoprofen in an effort to minimize side effects, improving patient compliance and ensure the achievement of therapeutic targets. This study aimed to optimize the formulation of ketoprofen matrix patch transdermal. The optimizing process was analyzed by simplex lattice model. Determination of the level of ketoprofen released was carried out by spectrophotometer UV-Vis. Interpretation of the dissolution profile can be seen visually fit between the model constructed from the zero-order approximation, first-order, Higuchi, Korsmeyer-Peppas, Weibull, Hixson-Crowell and Baker-Lonsdale. The results provide information that a combination of MC and HPMC polymers have a significant influence on increasing the patch weight, patch thickness, loss on drying and dissolution efficiency and insignificant effect against folding endurance. The optimal formula is generated by a combination of HPMC:MC (0.1:0.9) and produces a patch matrix with weight, thickness, drying loss, and DE were 0.68 g, 0.36 mm, 12.42%, and 23.21%, respectively. The release kinetic of ketoprofen followed Korsmeyer-Peppas model through the mechanism of non-Fickian diffusion.

Rifampin is one of first-line drugs for the treatment of tuberculosis. In Indonesia nearly alltuberculosis patients show lower rifampin plasma concentrations possibly due to genetics.Rifampin is a substrate of the organic anion-transporting polypeptide 1B1 (OATP 1B1)encoded by the solute carrier organic anion transporter family member 1B1 (SLCO1B1).This study aimed to identify haplotype polymorphisms of tuberculosis drug transporterswith an impact on clinical outcome in tuberculosis patients. Thirty-six patients from AbdulWahab Sjahranie General Hospital, Samarinda, East Kalimantan were involved in thestudy. Buffy coat from patient blood samples were tested for SLCO1B1 and SLCO1B3polymorphisms by RFLP and ARMS PCR, whereas the clinical outcome was examinedbased on the sputum conversion. The frequency of patients with SLCO1B1*15 haplotypewas 63.9%. The SLCO1B1*15 haplotype was associated with susceptibility to failureof clinical outcome (p=0.005; RR=4.52; 95% CI: 1.22-16.64). The OATP1B1*15haplotype revealed that the failure of clinical outcome was markedly increased comparedto the three other haplotypes. These results suggest that the SLCO1B1*15 haplotypeis an important predisposing factor for lower clinical outcome. Our data indicate thatindividualized treatment should be considered for Indonesian tuberculosis patients basedon genetics characteristics of patients.

The papaya leaf decoctions have been widely used as a traditional treatment for malaria. The alkaloid of papaya leaves, carpaine, is reported to have the antiplasmodial activity in vitro. The industrial-scale commercial product development requires the quantification of the carpaine, and total alkaloids in the papaya leave as the raw materials. This study aims to optimize the extraction process leading to the highest yield and total alkaloids. The extraction process was carried out using different methods and solvents. The first method was maceration with the water-miscible solvent of ethanol: distilled water: HCl 37% (89: 10: 1 v/v/v). The second method was maceration with the water-immiscible solvent of dichloromethane solvents in pH 8-9 with ammonium hydroxide. The third method was digestion with acid water solvent of 0.05 N HCl. The identification of alkaloids employed the analysis using Thin Layer Chromatography (TLC) and Dragendroff reagent. The quantification of carpaine used a densitometer, while the spectrophotometric method was used to estimate the total alkaloids. The results showed that despite the extraction methods used, the tested extracts confirm the alkaloids content with the highest yield of 3.09% (84.72% of total alkaloids).

Although it has been developed since 1972, the implementation of a population-based modeling approach in Indonesia, particularly to analyze biopharmaceutics and pharmacokinetics data is still very limited. This study was aimed to evaluate the performance of Monolix and NONMEM, two of the popular software packages in a population-based modeling approach, to analyze the limited data (sparse sampling data) of the time profiles of the simulated plasma drug concentration of a theoretical compound. and NONMEM were used to model the limited data (40 data points) as a results of the random selection from the 180 point data of simulated plasma drug concentration (Cp) on 20 subjects at 0.25; 0.5; 0.75; 1; 1.5; 3; 6; 12 and 18 hours after per-oral administration of a 100mg of a theoretical compound. Population values of the absorption rate constant (Ka), the elimination rate constant (Kel) and volume of distribution (Vd) were compared to the average Ka, Kel and Vd obtained by the conventional method (two stage approach) using PKSolver on the Cp data of all subjects. The calculation system of a nonlinear mixed effect model in Monolix and NONMEM, successfully describes the sparse data, based on the visual evaluation of the goodness of fit. Comparison of parameter estimates of population values in Monolix and NONMEM are in the range of 94 to 108% of the real values of the rich data analysed by PKSolver. A population-based modeling can adequately analyze limited or sparse data, demonstrating its capability as an important tool in clinical studies, involving patients.

Aspirin has low solubility in water therefore, dissolution is a rate limiting step for absorption. Floating tablet formulation is designed to improve the bioavailability of aspirin. The objective of this study was to determine in vitro dissolution study of aspirin floating tablet release kinetics model. The floating tablets were prepared by a direct compression method using Methocel K4M CR, NaHCO3, Ethocel, Aerosil, and dicalcium phospate anhydrous as excipients. Tablets were evaluated by different parameters such as physicochemical properties, floating lag time (Flag time), total floating time, and dissolution. The result showed that the tablet mass has good flow properties of 13.54 g/sec. Aspirin floating tablets had a weight uniformity (CV=1.45%), good hardness (6.42kg), and low friability (0.158%). The tablet has a short Flag time of 25.16 sec and long floating time of 8 hours. Dissolution data were evaluated using DDSolver conducted by (1) Statistical parameters: R2adjusted, AIC, MSC; (2) Visual goodness of fit (GOF). The results showed that aspirin floating tablets release kinetics followed the Korsmeyer-Peppas model. Aspirin release occurs through the mechanism of anomalous transport which combines Fickian diffusion and polymer relaxation.Key words: aspirin floating tablet, DDSolver, modeling of drug release

Atenolol has a low oral bioavailability and a short elimination half-life. Therefore, alternative route and delivery system is important. Transdermal iontophoresis, i.e. a systemic drug delivery via the skin, implementing a low intensity of electrical current, is one attractive candidate. This study evalu ated feasibility of atenolol transdermal transport when iontophoresis is applied after enhancer pretreatment. There were 4 formulas prepared; 2 implemented iontophoresis for 3 hours (current density: 0.25 mA/cm2) while the others did not use iontophoresis. The enhancer was oleic acid (5 or 10% as a mixture in propylene glycol) with duration of pretreatment of one hour. Transport was evaluated in the diffusion studies across the fresh rat skin in a static-vertical diffusion system. Data were analyzed based on the numeric convolution method to obtain simulated Cp profiles as well as AUC of Cp profiles. Based on the simulated Cp, the best transport was achieved in Formula 3, where iontophoresis is performed across the skin, pretreated with 5% oleic acid for one hour. The value of simulated Cp indicated achievement of therapeutics level of atenolol, suggesting the feasibility of the atenolol delivery by iontophoresis.Key words : atenolol, transdermal, iontophoresis, enhancer

Propranolol has an intensive first pass metabolism, resulted in a low oral bioavailability. One alternative to circumvent such problem is the delivery by transdermal route. The objective of this study was to evaluate the effect of oleic acid 10 % (in propylene glycol 20 %) as enhancer, with and without iontophoresis, on transdermal transport of propranolol. Propranolol delivery was examined based on the in vitro transport studies across the rat skin (after hair removal) in a vertical diffusion cells system. Skin was pretreated with the mixture of oleic acid 10 % (in propylene glycol 20 %) for 3 hours. Iontophoresis was performed at a current density of 0.25 mA/cm2 for 3 hours. Donor compartment was filled with propranolol solution (5 mg/mL in citric buffer pH 5), while the acceptor phase was filled with phosphate buffer saline at pH 7.4. The results indicate that the enhancement methods increase the transdermal penetration of propranolol (p<0.05). The flux without any enhancement methods was 13.16 ± 0.79 mg/cm2/hour. The flux with either oleic acid-propylene glycol pretreatment, iontophoresis or combination of both were 28.75 ± 3.04 mg/cm2/hour, 40.47 ± 5.78 mg/cm2/hour, and 85.42 ± 16.94 mg/cm2/hour respectively. Based on mathematics calculation, if an iontophoretic patch of 12 cm2 is used after skin pretreatment with oleic acid - propylene glycol mixture, the steady state plasma concentration of propranolol could reach 24.65 mg/mL. Therefore, therapeutic level might be achieved. This indicated a promising future of transdermal delivery of propranolol.Key words : propranolol, transdermal, enhancer
