ABSTRACT
Metformin hydrochloride, the only available biguanide, remains the first line therapy for treating type 2 diabetes mellitus acts by decreasing hepatic glucose output and peripheral insulin resistance. It has relatively short plasma half life, low absolute bioavailability. The need for the administration for two to three times a day when larger doses are required can decrease the patient compliance. Sustained release formulations that would maintain plasma level for 8-12 hrs might sufficient for daily dose Metformin HCL presents significant challenges due to its poor inherent compressibility, high dose and high water solubility. The present study was to design metformin extended release by using hydrophilic controlled release polymers polyvinyl pyrrolidone, sodium carboxymethyl cellulose, polyoxrs301, carbopol 971P by wet granulation method. The formulated granules blend was evaluated for flow property parameters. In-vitro dissolution studies were carried out in pH 6.8 phosphate buffer using the apparatus type 2 paddle type described in the USP monograph. From the different formulation and its data’s we find the optimized formula which is similar to the innovator product. From the stability data analysis the optimized formula complies with that of innovator.
Key Words:- Metformin hydrochloride, Controlled release tablets, In-vitro dissolution studies.

ABSTRACT
The field of corneal tissue engineering has made many strides in recent years. Tissue-engineered corneal scaffolds could provide significant benefits as an alternative to donated corneas. The novelty of the study lies in the development of scaffold from pen of Indian squid (Loligo duvauceli), for corneal tissue engineering. Squid pens are the waste products of food processing industry and this study explored a single-step method for isolation of chitosan from squid pens. Chitosan and chitosan scaffolds were characterized for their physico-chemical, mechanical and biological properties. Infra-red analysis revealed 80% degree of deacetylation, scanning electron microscopic studies elucidated smooth surface morphology of transparent chitosan scaffold, with required tensile strength. Optical clarity of chitosan scaffold ranged between 80-88% and it supported the growth of human corneal epithelial cell line. This chitosan scaffold with good transparency, biocompatibility and mechanical properties could be a promising material for corneal tissue engineering applications. This study also unveils an economically feasible technology for the conversion of waste into wealth.
Key Words:- Corneal tissue engineering, Chitosan, Squid pen, Scaffold, Cornea.

ABSTRACT
Using low-dose morphine in intrathecal space before surgery, provides sufficient analgesia and reduces the side effects of intravenous analgesic medications. Due to the established tolerance to narcotic drugs in addicted patients, and also the lack of a study that specifically compare Effects of intrathecal morphine on postoperative pain in CABG surgery addicted persons, in this study it is tried to compare Effects of intrathecal morphine on postoperative pain in CABG surgery addicted persons. Among patients for CABG surgery, a total of 60 patients 40-70 years old with a history of drug abuse, were selected in randomized, clinical trial. Patients were divided into two groups of 30. For the first group, before induction of general anesthesia, 4microgram/kg of morphine was injected into the spinal space. the second group was also placed in a sitting position for 5 min. Postoperative amount of pain were recorded at 1, 4, 8, 12 and 24 hours after extubation. The first time of analgesic request by the patient and the total amount of postoperative opioid consumption was also recorded. The amount of pain in the group receiving intrathecal morphine at 1, 4, 8, 12 and 24 hours after extubation, was significantly lower than in the placebo group (P<0.05). The first time of analgesic request by the patient in the group receiving intrathecal morphine was significantly longer than the control group (P = 0.04). The total consumption of morphine for analgesia in a 24-hour period after surgery, in the group receiving intrathecal morphine was significantly lower than the control group (P = 0.001). The administration of Intrathecal morphine before surgery in addicted patients undergoing coronary artery bypass surgery, is able to reduce the pain in the first 24 hours after surgery and reduces the need for narcotics in 24 hours after surgery.
Key Words:- Postoperative Pain, CABG Surgery, Intrathecal Morphine.

ABSTRACT
The escalation of drugs and the related information in the 1900’s expanded and transformed the role of the pharmacist from the dispenser of drugs to that of the educator of both health care professionals and the patients regarding the medications in order to provide better outcomes for drug therapies. However, the recognition of this role in developing nations like Pakistan is still not observed due to lack of interaction and knowledge among the masses and the health care providers and the perception of a pharmacist as a patient counselor is still not established. A mix model design was selected targeting the physicians of Pakistan. 432 were sent questionnaires and 401 responded giving a response rate of 92.8%. The survey employed cross tabs and Chi square X2 test. The qualitative insights were given in quotes from Physicians as a generalized opinion. The aim was to describe a collective opinion of physicians evolving in Pakistan. A mixed response was seen, half of the physicians (45.5%) were willing to incorporate a pharmacist but as the other half was unwilling (45.6%). Few were unsure about the outcome (8.9%). The gender was associated with the perception. (P value <0.05). Those who responded in favor were of the view that a pharmacist is an important component in the health care system but those unwilling believed that a pharmacist involved in patient counseling will shift the patients’ confidence from the physicians towards themselves. The role of pharmacist within the developing countries like Pakistan is still recognized mainly as that of a dispensing professional and acceptance in a clinical setup by the physicians and the patients is still an ongoing process that can only be successfully implemented by reforms in the health care system as a whole.
Key Words:- Perceptions, Physicians, Patient Counseling, Quantitative, Qualitative, Pharmacist, Pakistan.

ABSTRACT
The pharmaceutical importance of Allium sativum is due to the presence of carbohydrate, protein, vitamins, essential metal and organosulpher compounds. Allicin is one of the active ingredients of freshly crushed garlic homogenates and showed a wide spectrum activity. The antimicrobial activity of different concentration of allicin against gram positive and gram negative bacterial isolate was studied by standard protocols. The maximum zone of inhibition has been observed in Bacillus subtitis and minimum for Proteus mizobills. The minimal inhibitory concentration (MIC) varies bacteria to bacteria and fungus to fungus respectively. The effect of time, temperature and pH were also studied. The antibacterial efficacy was maintained at room temperature for maximum one week and maintains for longer time only at low temperature. Antimicrobial activity of garlic come from allicin, is mainly due to S-S and S-O bond which has the ability to react with thiol containing enzyme to form S-thiolation product, the broad spectrum antimicrobial effects of allicin is due to the multiple inhibitory effects on various thiol dependent enzymatic systems. The results indicate that allicin has antimicrobial activity.
Key Words:- Allium sativum, A.I, Antimicrobial activity, Richard’s liquid medium.
