Inflammatory bowel disease (IBD) (ulcerative colitis and Crohn’s disease) is an idiopathic, chronic inflammatory condition, which affects the gastrointestinal tract.The present study was carried out to evaluate the effect of ethanolic extract of Nigella sativa in experimentally induced inflammatory bowel disease (IBD) in rats. Colitis was induced by a single intra-colonic application of 20 mg 2,4,6-trinitrobenzene sulfonic acid (TNBS) dissolved in 35% ethanol into the descending colon. Rats were divided into six groups. Animals were treated with vehicle (ethanol), TNBS dissolved in 35% ethanol, Ethanolic extract of Nigella sativa seeds (ENS) 100, 200 and 400 mg/kg body weight p.o. and sulfasalazine(SSZ) 360 mg/kg body weight p.o. for 14 days. After completion of 14 days of treatment, animals were sacrificed and the following parameters were assessed morphological score, histopathology and biochemical parameters like myeloperoxidase (MPO), malondialdehyde (MDA), reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) activity and serum nitrate levels. Nigella sativa provided protection against TNBS-induced colonic damage. There was significant protection with ENS 200 and 400 mg/kg body weight compared to control (P <0.001). Morphological and histological score were significantly reduced in all the treated groups (P<0.001). All parameters were altered in ulcerated rats, and improved in animals receiving ENS, an effect that was comparable to that of the standard sulfasalazine, especially at the highest dose level. Results indicate efficacy of ENS against TNBS induced experimental colitis in rats.

Aim of the present study was to develop immediate release tablets of loratadine. Loratadine immediate release tablets were formulated by using different ratios of different superdisintegrants like sodium starch glycolate and kollidon CL with direct compression method. Tablets were prepared and evaluated for different quality parameters. A comparison of commercial loratadine tablets has also been evaluated. The percent releases of the all formulations (total six) were from 91.47%- 98.70% after 1 hr dissolution studies. Best formulation was F3 because of lesser disintegration time and highest percentage drug release at the end of 1 hr. On the other hand, sample-A released 99.83% of drug while sample-B released 99.04% of drug within 1 hr from release pattern of commercial product of loratadine tablets. The study reveals that the superdisintegrants of the study have the capacity to speed up the release of the drug from the immediate release tablets and the more is the amount of the superdisintegrants in the formulation the more is the release of drug showing more immediate action of drug release.

Persistent post-infectious cough (PPC) is a subacute cough lasting less than 8 weeks.  This article aims to review recent advances in the pathophysiology and pharmacotherapy of PPC secondary to upper respiratory tract infection.  Between April and August, 2016, relevant databases were searched using the search words “subacute cough,” “persistent post-infectious cough,” “post-viral cough,” “causes,” pathogenesis,” and “management.” Inflammatory mechanisms play a reported role in the pathophysiology of PPC. Interplay of mediators such as neuropeptides, cysteinyl leukotrienes, Th1-like and Th2-like cytokines and gamma interferon, has been suggested. Combination of ‘Honey and ‘Coffee’ and Suhuang Zhing, a traditional Chinese medicine is reported to demonstrate clinical efficacy in clinical trials. Natural products and herbal medicines appear to be superior to conventional treatments.

Single dose vials are considered to be used for single dose and single patient only. Many infection outbreaks reported previously by using single dose vials for multiple dosing were mainly due to improper handling by health care workers. However, under certain circumstances it is permissible to use single dose vial for multiple dosing. In present study, sterility and stability of 50 acetaminophen single dose vials were analyzed for 24 hours by withdrawing samples at different time intervals after the initial first spiking of vial by using basic aseptic techniques. The sterility was examined by inoculating samples on thioglycolate broth, nutrient agar and Sabouraud’s Dextrose agar but none of the samples found contaminated. The stability was evaluated by UV-visible spectrophotometric method. One way analysis (P-value=0.152) reject the null hypothesis and did not reveal any significant differences among samples at different time intervals. The study concludes the use of the SDV for multidosing provided the prevention of contamination in the system.

High strength tablets containing 500 mg or more active ingredients could affect the dissolution of concomitantly administered drugs. Dissolution of ten generic solid dosage forms was determined in the presence of sodium bicarbonate and paracetamol, 500 – 2250 mg. In a total of 111 dissolution tests 41 failed (37%) to meet the criteria. Where paracetamol was present 36 out of 50 end points failed (72%) with an extreme case in diltiazem tablets with 0% dissolution. Since longest test end points with failures mostly range from 60 – 90 minutes it is advisable to administer paracetamol 1.5 hours after other drugs in order to avoid potential pharmacokinetic disturbances.a

Background: Quinolones are among drugs used in the treatment of urinary tract infections (UTIs). However, there has been an increase in quinolone-resistant uropathogens over the last decade. The aim of this study was to assess the sensitivity pattern of isolated uropathogens to levofloxacin. Methods: Urine samples (n = 519) from suspected UTI patients were collected from July 2014 to September 2014. Microorganisms with significant growth were identified after initial culturing at 37°C for 24 hours. Susceptibility of isolated uropathogens to levofloxacin at a break point of 5 µg was done by the Kirby-Bauer disc diffusion method. Results: The prevalence of UTI among sampled patients was 18.3%. Predominant microbial isolates were: Escherichia coli (56.8%), Coliform spp. (24.2%) and Staphylococcus aureus (9.5%). Overall resistance of isolated uropathogens to levofloxacin was 51.6%. Levofloxacin resistance by predominant uropathogens was 63% for E. coli, 34.8% for Coliform spp. and 22.2% for S. aureus. Conclusions: High resistance of some isolated uropathogens to levofloxacin, especially with E. coli was observed in this study. Thus, the need for coordinated susceptibility monitoring of clinical isolates to levofloxacin.

The aim of this study was to assess the physicochemical properties of a solid dispersion of L-ascorbyl 6-palmitate (ASCP) as poorly water soluble and ?-cyclodextrin (?CD) prepared by co-precipitation or co-grinding by using powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (solution state 1H-NMR and solid state 13C-NMR), and solubility test. Physical assessments and measurements indicated that a co-precipitate of ASCP and ?CD resulted in inclusion complex formation at a molar ratio of 1:3 and that a ground mixture of ASCP and ?CD resulted in inclusion complex formation at a molar ratio of 1:2. A solubility test revealed that the co-precipitate and ground mixture had improved solubility compared to ASCP alone. The co-precipitate had greater solubility than the ground mixture. This result is presumably due to molecular interaction occurring as result of the differences in the molar ratios and differences in the structure of complexes for ASCP and ?CD in a solid state.

When providing comprehensive medication management (CMM) services, pharmacists must recognize patients’ medication experiences to make patient-centered decisions. The aim of this study was to understand how patients’ medication experiences are applied in pharmacists’ decision-making process during the provision of CMM services. Using grounded theory, we devised a theoretical proposition, which derived from narratives of 11 pharmacists, observations of CMM consultations and clinical case discussions.  The results suggested that understanding the patient’s medication experiences can guide the professional to identify and resolve drug therapy problems. According to the participants, the medication experience can lead the practitioner to two courses of action: to improve health literacy, helping the patient overcome barriers to medication use; or to adapt the intervention, matching the pharmacotherapy to the patient’s routine. This knowledge can be used as a guide to teach pharmacy students and novice pharmacists how to incorporate patients’ medication experiences into clinical decision-making.
