The quality of medicines depends not only on the active principles and production processes, but also the performance of the excipients, hence we say’ Excipients are Cindrellas of Formulation’. The traditional concept of the excipient as any component other than the active substance has undergone a substantial evolution from an ‘inert’ and cheap vehicle to an essential constituent of the formulation. The rapid evolution of scientific, regulatory and economic factors, the introduction of delivery systems and the advance in biopharmaceutics have led to a new interest in the role and functionality of the excipients. There are number of raw materials available from a multitude of sources used in pharmaceutical industry where their chemical structures vary from small polymer to long chain polymer. Excipients are now chosen to perform a variety of functions which guarantee the stability and bioavailability of the drug substance and its manufacturability on a large production scale. Beyond the dosage form necessities, excipients particularly in the case of solid dosage forms are used. As a consequence,...

The main objective of this study is to evaluate the antibacterial activity and phytochemical analysis of Lemon (Citrus limon L.) and Orange (Citrus sinensis L.) Increasing resistance of microorganisms to present day antibiotics arose a way to focus on antimicrobial activity and future prophylactic potential of the lemon and orange peels. In the present study, a total of two extract each of Methanol & Ethanol of Citrus limon and Citrus sinensis were evaluated for their antibacterial activity due to the phytochemicals present in the both the fruit’s peels. All the extracts showed antibacterial activity against all the four bacterial stains. The antibacterial activity of Methanolic and Ethanolic peel extract of C. limon L. and C.sinensis L. were evaluated on bacterial strains Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and Staphylococcus aureus by recording minimum inhibitory concentration (MIC) by disc diffusion method. Methanolic extract of C. sinensis showed maximum inhibition zone of 17 mm against S....

Background: Psychiatric disorders are one of the major causes of morbidity. Development of newer drugs like selective serotonin reuptake inhibitors and atypical antipsychotics has altered the treatment paradigms. Objective: To study drug utilization pattern of psychotropic drugs in psychiatric outpatient department. Material and Methods: After ethical approval six month observational, prospective study was conducted at tertiary care hospital, South India. Prescriptions containing at least one psychotropic drugs were included. Data was measured for number and percentage of prescriptions or drugs and using selected World Health Organization (WHO) drug use indicators. Microsoft excel was used to summarize and graph pad instat was used for analysis of data as appropriate.(P < 0.05). Results: 101 prescription contained 187drugs (1.851±0.8 per prescription) where 67.33% of prescriptions had more than 2 psychotropic drugs introducing psychiatric polypharmacy. Selected WHO drug use indicators showed some potential problems in prescriptions which can be improved. Antidepressants (41.49%) were prescribed more followed by sedative/hypnotics (34.69%), antipsychotics (16.3%) and antimaniac drugs (7.4%). Among antidepressants, Sertraline was highly prescribed followed by...

Oral route of drug delivery is the simplest and most accepted way of administration of drugs due to greater stability, high patient compliance, accurate dosage, cost effectiveness and high patient compliance of drugs. But with oral formulations bioavailability is the major problem for newly discovered drug because 40 percent are lipophilic compounds. There are several factors responsible for low oral absorption of hydrophobic drugs and one very particular one is poor absorption due to slow and/or incomplete drug dissolution and precipitation in the gastro-intestinal lumen or other aqueous media. Therefore in order to be delivered orally and to achieve acceptable bioavailability, lipophilic drugs require a co-administered drug delivery system. This article mainly gives overview of technologies available with special emphasis on mechanism of SEDDS and potential for commercialization of formulation as compared to other technologies along with examples. But there are certain disadvantages of SEDDS like lack of good predicative in vitro models for assessment of the formulations and higher concentrations of surfactant used may cause some allergic reactions....

Objective: To compare the drugs: Midazolam and diazepam as preoperative medication. Materials and methods: 100 patients aged between 18-60, scheduled for elective surgery were included in this comparative study. Patients were randomly allocated into two groups of 50 each. Materials and methods: Patients received 0.08mg/kg body weight midazolam inject intramuscularly and diazepam 10 mg orally. Assessment of efficacy variables: anxiety, sedation and anterograde amnesia were rated before and after drug administration (at 15, 30 and 60 minutes after drug administration) before surgery. Finidings: It was found that there was significant difference in mean anxiety reduction (p<0.001). Immediately before taking to operation theatre i.e. 60 minutes after drug administration, 5 with diazepam and 13 with midazolam were highly sedated. Midazolam demonstrated the better sedative, amnesic and anti anxiety effects than diazepam. Conclusion: With respect to anxiolytic, sedative and anterograde amnesic properties, midazolam (0.08mg/kg intramuscularly) is better premedicant compared to diazepam (oral 10 mg) for patients at preoperative period. Diazepam is also a good premedicant and use of both drugs is...
