The plant Irvingia gabonensis contains lipids and polymer extractives that can be a good source of excipients for oral pharmaceutical formulations. These constituents are usually extracted from the seeds with the aid of either organic solvents or enzymes. The purpose of this paper was to describe a novel, simpler, cheaper, and safer method for the simultaneous extraction of lipids and gum from I. gabonensis. A 100.0 g of seeds of I. gabonensis in 200 mL deionized water was heated at 78°C in the presence of 2.0 g sodium chloride for 1 h, and the mixture was allowed to stand for the lipids to be separated and removed by filtration. The samples were air dried at 25-30°C. The liquid fraction was centrifuged at 3445 rpm for 30 min, and the supernatant portion containing the gum was freeze dried. The samples were investigated for their true, bulk, and tapped densities as well as particle size and particle size distributions. The rheological, and near infrared absorption spectra as well as thermal behavior of the samples were also studied. The lipid and the polymeric components of I. gabonensis seeds were successfully extracted simultaneously. The true densities of the fatty and gum components were, respectively, 1.000 and 1.544 g/cm ³ . The melting point of the fat was 40°C and T_g of the gum was 232°C. These values were similar to those described in the literature for the components using the traditional method, demonstrating the effectiveness and efficiency of this simple novel method.

To study the diuretic effects of cleistanthin A and cleistanthin B, phytoconstituents were isolated from the leaves of Cleistanthus collinus in Wistar rats. The in vivo diuretic effects of cleistanthins A and B were determined according to the Lipschitz test. Prior to the experiment, the animals were fasted for 5 h and placed individually in metabolic cages. Cleistanthins A and B (12.5, 25, and 50 mg/kg) and furosemide (5 mg/kg) were suspended in 0.5% w/v carboxymethyl cellulose and administered orally. The urine was collected up to 5 h after administration and subsequently up to 24 h after administration. The acidity and urine volume were measured immediately. The urinary sodium and potassium levels were determined using a flame photometer, and the chloride level was determined by argentometric titration. The diuretic index and diuretic activity were calculated mathematically. While cleistanthins A and B showed a diuretic index of more than one, the diuretic activity of these compounds was less than one, indicating inferior activity compared with furosemide. Both cleistanthin A and B produced a significant increase in the urine volume and alterations in urinary electrolyte levels. However, the effect of the compounds was not dose dependent. Cleistanthin A and cleistanthin B exert diuretic effects in male Wistar rats without affecting the urinary acidity.

This study was carried out to investigate the effect of Aloe vera extract (AvE) on serum electrolytes, urea, and creatinine as indices of renal function in Sprague-Dawley rats. Twelve male Sprague-Dawley rats weighing between 80 and 130 g were used. Rats were divided into two groups: The control and the test groups (n=6). The test group received 1 ml of AvE daily for 28 days. Both the groups fed on standard rat chow and water ad libitum. The results showed a decrease in serum levels of sodium, and potassium, but an increase in the serum levels of bicarbonate, urea, and creatinine in the test group. The changes seen were, however, statistically insignificant, except for the serum levels of sodium and creatinine (P<0.05). It is thus concluded that AvE impairs renal handling of electrolytes with consequent hyponatremia and hypercreatinemia. However, this might be of therapeutic value in conditions associated with hypernatremia.

Nitrogen heterocyclic compounds such as pyrazolines have been found to possess a broad spectrum of biological activities such as anticancer, antitubercular, anti-inflammatory, analgesic, and antidepressant activities. Pyrazoline derivatives IV, V (a-e) have been synthesized from the intermediate chalcones III (a-h) by cyclizing with phenyl hydrazine and hydrazine hydrate. The structures of these compounds were confirmed by IR, NMR, and mass spectroscopy. Biological studies of the synthesized compounds showed promising antitumor, analgesic, and anti-inflammatory activities. The compounds were tested for their in vitro antitumor activity against EAC tumor cell lines. Compounds IVa and IVb showed the highest cytotoxicity of 80% at a 200 μg mL concentration. Among the tested compounds, IVa and Vd seem to be more effective analgesic agents. Compounds IVc, IVd, and Ve are found to be the most effective anti-inflammatory agents. Thus the results show that synthesized compounds possess antitumor, analgesic, and anti-inflammatory activity. It was observed that the test compounds with electron withdrawing groups (halogens) on the aromatic ring favors antitumor, analgesic, and anti-inflammatory activity.

A rapid, simple and sensitive high-performance liquid chromatography (HPLC) method has been developed for quantification of olmesartan medoxomil (OLM) and amlodipine besylate (AM) in plasma. The assay enables the measurement of OLM and AM for therapeutic drug monitoring with a minimum detectable limit of 2 ng mL. The method involves a simple, one-step extraction procedure and analytical recovery was above 50%. The separation was performed on an analytical 250 × 4.6 mm Eurospher 100 ^-5 C18 column. The wavelength was set at 239 nm. The mobile phase was a mixture of acetonitrile:0.05 M ammonium acetate buffer: 0.1 mL triethylamine at pH 6.8 was selected at a flow rate of 1.0 mL min. The calibration curve for the determination of OLM and AM in plasma was linear over the range 2-2500 and 8-10,000 ng mL AM and OLM. The coefficients of variation for interday and intraday assay were found to be <15%. The method can be applied to a pharmacokinetic and pharmacodynamic study of OLM and AM in a combined dosage form.

Hypertension is the very common chronic disease in rural, urban and semi-urban areas of today's world, which needs continuous monitoring and treatment through out the life. Lack of education, lifestyle modification, and low level of understanding on disease management in rural people will influence directly on their quality of life (QOL). The objective of this study was to know the impact of clinical pharmacist interventions on medication adherence and QOL. It was a prospective, randomized and interventional study. Fifty-six patients were enrolled; only 52 patients completed the study. Interventional group patients received patient counselling, patient information leaflets (PILS), and frequent telephonic reminding. In the baseline, first and second follow-ups, medication adherence and QOL were assessed by using Morisky Medication Adherence Scale (MMAS) and Medication Adherence Report Scale (MARS) Questionnaires and SF-12v2 Quality of life Questionnaire in both the groups. The results showed that systolic blood pressure P value in the second follow-up was 0.086+ when compared to baseline follow-up P value 0.094. The diastolic blood pressure reading of the intervention group at the second follow-up was 77.73 ± 3.63 in mmHg when compared to the baseline, i.e. 86.62 ± 11.35 in mmHg. The MMAS and MARS scores P values were 0.007**, 1.000, <0.001**; 0.007, 0.014 and 0.000 at the baseline, first and second follow-ups, respectively. The QOL score P values of physical component scale and mental component scale showed highly significant. This study concluded/showed that the impact of clinical pharmacist provided patient counselling had a positive impact on medication adherence and QOL.

The study is aimed to explore the perceptions and experiences of hypertensive patients toward medication use and adherence. The study was qualitative in nature conducted at Sandamen Provisional Hospital of Quetta city, Pakistan; a public hospital catering to the health needs of about 40% of the population. A qualitative approach was used to gain an in-depth knowledge of the issues. Sixteen patients were interviewed, and the saturation point was achieved after the 14 ^th interview. All interviews were audio-taped, transcribed verbatim, and were then analyzed for thematic contents by the standard content analysis framework. Thematic content analysis yielded five major themes. (1) Perceived benefits and risks of medications, (2) physician's interaction with patients, (3) perception toward traditional remedies, (4) layman concept toward medications, and (5) beliefs toward hypertension and its control. The majority of the patients carried specific unrealistic beliefs regarding the long-term use of medication; yet these beliefs were heavily accepted and practiced by the society. The study indicated a number of key themes that can be used in changing the beliefs and experiences of hypertensive patients. Physician's attitude, patient's past experiences, and knowledge related to hypertension were noted as major contributing factors thus resulting in nonadherence to therapy prescribed.

The objective of this study was to evaluate consumers' perceptions regarding "modern medicines" in Penang, Malaysia. To conduct this exploratory study, qualitative techniques were used. Consumers more than 19 years of age and could speak English, who had visited a pharmacy in the last 30 days, were included from the four major areas of Penang. Eighteen interviews were conducted until the point of saturation. The interviews were audio-taped and then transcribed verbatim for thematic content analysis. Many consumers correctly identified the major characteristics and properties of modern medicines; however, others raised doubts regarding the safety, quality and efficacy of "modern medicines". There were many misconceptions such as "all modern medicines can cause dependence", traditional medicines are completely "free of side-effects" and "Western medicines cure while Chinese medicines don't". Color was also considered a strong determinant of the safety and characteristics of a medicine. Regarding consumers' "medicine information seeking behavior", many consumers would seek information from doctors and pharmacists; however, there were others, who would look for books, or get it from the internet and friends. Of concern many consumers emphasized that while "self-searching for drug information" they would only look for side-effects. Misconceptions regarding medicine-taking behavior, medicine use and compliance were also identified. Though several consumers complied with the medicine-taking instructions, many reported that they would stop taking medicines, once they feel better. Though many consumers correctly identified the characteristics of "modern medicines", misconceptions regarding "medicine information sources and "medicine-taking behavior" were rampant. The situation demands corrective actions including community-oriented educational campaigns to improve "medicine use" in the society.

Economic analysis plays a pivotal role in the management of medical store. The main objectives of this study were to consider always better control-vital, essential and desirable (ABC-VED) analysis with economic order quantity (EOQ), comparison of indexed cost and the actual cost, and to assess the expenditure for the forthcoming years. Based on cost and criticality, a matrix of nine groups by combining ABC and VED analysis was formulated. Drug categories were narrowed down for prioritization to direct supervisory monitoring. The subgroups AE and AV of the categories category I and II should be ordered based on EOQ. The difference between the actual annual drug expenditure (ADE) and the derived indexed cost using the cost inflation index (CII) was calculated. Linear regression was used to assess the expenditure for the forth coming years. The total ADE for the financial year of 2010-2011 was Rs. 1,91,44,253 which was only 7.68% of annual hospital expenditure. Using the inflation index, the indexed cost of acquisition of ADE for year 2010-2011 was Rs. 1,95,10,387. The difference between the two was estimated to be 2.11%. Thus, the CII justifies the demand of increased budget for next year and prompts us for cautious use of drugs. By taking into consideration the ADE of last 10 years, we have forecasted the budget for forthcoming years which will help significantly for making policies according to the available budget.

This study was aimed at identifying the types of medicines in pharmacy students' residence and to determine if a relationship exists between keeping medicines in students' accommodation and self-medication practices. A cross-sectional survey of a random sample of 240 undergraduate pharmacy students of the University of Jos, Jos, Nigeria, was carried out. Participating students were given a self-administered questionnaire, and only 188 students returned their filled questionnaire. The data collected were entered and analyzed using SPSS 16, and the χ² -test was used to determine associations between the variables. The results revealed that 66.0% of respondents had medicines in their room. A total of 318 medicines items (2.56 items per student's room) of which 37.1% were leftover medicines were present in respondents' rooms. Analgesics (34.3%) and antibiotics (25.2%) were the common classes of medicines present in respondents' rooms. Respondents reported getting these medicines on prescription (25.8%) and self-medication (56.5%) or both (17.7%). Self-medication practice was common among respondents (53.2%); however, no significant relationship (P>0.05) existed between having medicine in students' room and self-medication practices. Common reasons given by respondents for having medicines in their rooms were that they were leftover medicines and that they were keeping them for emergency use or for use in an event of a similar illness. Most respondents (72.2%) reported disposing of their unused medicines in a trash can/dust bin. This study demonstrated that the prevalence of medicine storage in students' room and self-medication practice is high. Analgesics and antibiotics were the most common types of medicines present in students' residence.
