Introduction: Self Medication (SM), a form of self care, is a topic of growing interest among researchers and a matter of concern for policy makers and implementors, owing to a plethora of associated malpractices in general population. There is paucity of information about this menace, especially in developing countries. The objective of the present study was to assess the prevalence, pattern and determinants of self medication among adult residents of a district in North India. Methods: This community based cross sectional mixed method study was carried out in of a district S.A.S, Nagar, Mohali, Punjab, India. Multistage stratified random sampling technique and Probability proportional to size (PPS) was used in the 400 households from urban, rural and slum areas. A pretested questionnaire was administered to one representative member of each of the 400 households. Besides 150 people visiting medical stores were interviewed for self medication practices. Results: SM was widely practiced (97%) in study population, more in urban as compared to rural and slum counterparts. People of all socio...

One of the major challenges in pharmaceutical development is the poor dissolution performance of drugs. Celecoxib (CLX) is a poorly water soluble drug with its bioavailability being limited by its poor dissolution. In this study spray drying method was employed to prepare CLX: PVP K30:HPB (hydroxypropyl β-cyclodextrin) amorphous ternary system (ATS). Statistical experimental design was employed to investigate the combined effect of two experimental factors, i.e., % of polyvinayl pyrrolidone (PVP) K30 and % of HPB on saturation solubility (SS), dissolution efficiency (DE) and mean dissolution time (MDT), considered as the responses to be optimized. Design of experiment was used in the context of quality by design, which requires a multivariate approach for understanding the multifactorial relationships among experimental factors. Central composite design allowed for defining a design space. Desirability function was used to attain simultaneous optimization of all responses. The desired goals were achieved for SS, DE and MDT. Experimental values obtained from the optimized formulations were very close to the predicted values, thus confirming the validity of...

Background: Narikela lavana is a classical formulation which has been described in the samhitas such as Chakradatta, Vangsena, Bhavaprakash, and Rasa tarangini. The main indication of Narikela lavana is Parinaam shoola which can be broadly correlated with Peptic ulcer as per the modern parameters. As the name suggests, Narikela lavana contains only two ingredients- Narikela (coconut) and saindhava lavana (rock salt). Aim: In the present study, Narikela lavana is prepared by the method prescribed in Rasa tarangini and its characterization is done. Materials and Methods: Narikela lavana have been characterized with the help of Physico-chemical analysis, Physical and flow ability parameters, Fourier transform infrared spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDAX). Results and Discussion: Narikela lavana is nanocrystalline material having alkaline pH and hygroscopic nature. Its activity on hyperacidity is due to the presence of activated charcoal and alkaline nature. Conclusion: Narikela lavana could prove to be highly effective in hyperacidity (amlapitta) and peptic ulcers (Parinaam...

Inconsequential use of broad-spectrum antibiotics results in the evolution of multiple drug resistant pathogenic gram-negative bacterial strains which is a global health threat and is responsible for high morbidity and mortality rates. This necessitated the search for new effective and safe treatment strategies. One such successful treatment strategy is combination therapy which comprises cow urine distillate and medicinal plants extract. In the present report, this combination therapy was used against five pathogenic gram-negative bacteria- S. typhimurium, K. pneumoniae, E. coli, E. aerogenes and V. cholerae. It was observed that combination therapy had more profound effect than the individual plant extract against all the bacterial strains at the specified level. Combination therapy with T. erecta plant extract was found to be the most effective which improved the antibacterial effect 2.54 times more against E. coli. Other plants extract also improved their antibacterial potential when used with CUD (R.A.I=1.28 to...

Purpose: To prepare and evaluate floating tablet of curcumin for prolonged gastric residence time and increased drug bioavailability for the treatment of gastric problem. Methods: Floating tablet were prepared by wet granulation method using different ratios of Curcumin, Psyllium husk, HPMC K 15 M, HPMC K 100 M and Mangifera indica gum. The respective powders were blended thoroughly and a dump mass was prepared by adding the granulating agent. Dump mass was passed through sieve number 10 and dried in hot air oven at 50 0C for 30 mins. After drying, granules were further passed through sieve number 22 to attain the uniformity in granules. Finally, optional additives like magnesium stearate and talc were added and finely blended for preparation of floating tablet. Result: Floating drug delivery tablets were being formulated and the present study focused on the formulation of FDDS by using different polymes like phyllium husk, HPMC K 100 and HPMC K15 and to evaluate its efficacy in reducing ulcers caused by H.pylori. The Floating drug delivery...
