Formulation and Evaluation of Quality Parameters of Effervescent Granules from the Potent Antioxidant between Two Variants of the Adaptogenic Herb Ocimum tenuiflorum L.

Ocimum tenuiflorum L. is found throughout semitropical and tropical parts of Southeast Asia. In Nepal, O. tenuiflorum L. is popular with two variants: Krishna Tulsi consisting of purple-colored leaves and Sri Tulsi consisting of green-colored leaves. O. tenuiflorum L. is considered the queen of herbs and is a traditionally and clinically proven medicinal herb for its application and efficacy. However, no commercial pharmaceutical preparations of O. tenuiflorum L. are available using effervescent vehicles. Therefore, the present study aimed to compare the antioxidant activity of leaves from the two varieties of O. tenuiflorum L. and formulate and evaluate the quality parameters of effervescent granules of the potent extract. The antioxidant activity of O. tenuiflorum L. ethanolic extracts was evaluated by DPPH radical scavenging assay at 1, 10, and 100 µg/mL concentrations, where ascorbic acid was used as the positive control. The antioxidant activity of purple-leafed O. tenuiflorum L. was found to be higher than that of green-leafed O. tenuiflorum L. Therefore, effervescent granules of the ethanolic extract of purple-leafed O. tenuiflorum L. were formulated using the pharmaceutical excipients tartaric acid, citric acid, and sodium bicarbonate and the quality parameters of the granules were evaluated. The formulated granules met the quality parameters assessed from the angle of repose, bulk density, tapped density, Carr's Index, Hausner's ratio, effervescent cessation time, and stability studies. Thus, the formulated effervescent granules of O. tenuiflorum L. can be used for therapeutic purposes or as a functional food.

Formulation and evaluation of mucoadhesive buccal tablets of aceclofenac.

This project was aimed to formulate and characterize mucoadhesive buccal tablets of aceclofenac, utilizing different proportions of three polymers carbopol 934, hydroxypropyl methylcellulose, and sodium carboxymethylcellulose. Twelve batches of buccoadhesive aceclofenac were prepared by the direct compression method. The compressed tablets were then evaluated for physicochemical parameters such as hardness, thickness, weight variation, drug content, friability, swelling index, surface pH, and ex vivo mucoadhesion. In vitro dissolution test was conducted for 12 h according to Indian Pharmacopeia 2018, using the rotating paddle method in phosphate buffer of pH 7.4. Physiochemical parameters like weight variation (231.25-268.75 mg), hardness (8.32-11.56 kg), friability (0.04-0.2%), diameter (9.00 mm), thickness (3.8-4.05 mm), and drug content ((97.67-102.25%) were within the acceptable limit as per Indian Pharmacopeia 2018. The swelling index was reported to be in the range of 112.93-450.19%, at 8 h. The surface pHs of all the batches were in between 6.72 to 6.96. The mucoadhesive strengths (40.5-50 g) varied with the change in polymer concentrations especially of carbopol 934. The dissolution profile of all the batches varied greatly, with a maximum release of 109.41% (in batch 12 at 6 h) to a minimum release of 44.82% (in batch 3 at 12 h). Among them, only batch 1 ensured sustained and effective drug release (88.34% at 12 h) with appropriate swelling index (112.93%) and mucoadhesive strength (40 g). Fourier Transform Infrared Spectroscopy analysis showed no evidence of drug excipients interaction. Hence, the results concluded that buccal mucoadhesive aceclofenac tablets can be formulated. Furthermore, the property of the tablet not only depends on the concentration but also the behavior of the polymers used.

Disease proportions and drug prescribing pattern observed in a free health camp organized at Dhorphirdi Village Development Committee of Western Nepal.

BACKGROUND: Health camp is generally organized to provide health care services to the people deprived of health care facilities. The aim of this project was to assess the proportions of disease among attendees of health camp and study the drug prescribing pattern in a free health camp. METHODS: A case study was performed from 1 day health camp to determine the proportions of disease and drug prescribing pattern. Data collection was performed using log book maintained in the health camp and patient's demographic details, disease diagnosed and drug prescribed was obtained from same log book. RESULTS: A total of 317 patients were included in the study. The majority of the patients were in the range of 41-50 years. On the basis of study on ethnicity, Brahmins and Chettris, were found to be predominant ethnic groups with gastrointestinal disorders as the major disease. The total number of medications prescribed was 510, with non-steroidal anti-inflammatory drugs (NSAIDs) and antipeptic ulcer drugs being commonly prescribed. The average number of drugs per prescription and the percentage of antibiotics prescribed were 1.6 and 21.4%, respectively. It was observed that 96.8% of prescription was by generic names. Likewise, 100% of prescription included drugs from essential drug list. CONCLUSION: Majority of the patients were of working age group. Headache and fever were found to be the most prevalent cases and NSAIDs were the most commonly prescribed medications. The drug prescribing pattern of the free health camp complied with WHO recommended prescribing indicators.
