1.  A study of use of fixed dose combinations in Ahmedabad, India 
Indian Journal of Pharmacology  2014;46(5):503-509.
Objective:
The aim of this study was to evaluate the pattern of fixed dose combinations (FDCs) in Ahmedabad, a city in western part of India.
Materials and Methods:
Over a period of 24 months, prescriptions were collected from 24 pharmacy stores across 6 zones of Ahmedabad city. The information was recorded in pre-formed Data Record Form after written consent from the patients (or relative (s) of the patients). The pattern of use of FDC, rationality and seasonal variation in their use were analyzed. At the end of study, results were analyzed using Chi-square test.
Results:
Out of the total 1170 prescriptions, 941 (80.3%) contained 1647 FDC formulations. The average number of FDCs prescribed was 1.41 ± 1.04 (mean ± SD). The FDCs were more frequently prescribed in the age group of 31 to 40 years (23.7%) and in males (54.4%). FDCs were most commonly prescribed by oral route (92.7%). As per drug category analysis, a higher number of FDCs containing nutritional supplements (20.2%), and those for CNS (18.1%) complaints were prescribed. A seasonal analysis showed that FDCs were commonly prescribed for respiratory complaints (23.4%), central nervous system (CNS) complaints (20.3%) and as nutritional supplements (22.4%) in winter, monsoon and summer months, respectively. Only 5.8%, 9.8% and 10.9% FDCs prescribed were included in WHO (2010), National (2011) and Gujarat State (2011) Essential Medicines Lists (EML), respectively (P < 0.0001). Irrational FDCs that are banned or FDCs containing irrational active ingredients were 1343 (81.5%) and 203 (12.3%), respectively.
Conclusion:
FDCs are widely prescribed with seasonal influence in their use. FDCs containing banned or controversial ingredients are prescribed widely.

2.  In Vitro Activity of Doripenem, a Carbapenem for the Treatment of Challenging Infections Caused by Gram-Negative Bacteria, against Recent Clinical Isolates from the United States▿  
Antimicrobial Agents and Chemotherapy  2008;52(12):4388-4399.
Doripenem, a 1β-methylcarbapenem, is a broad-spectrum antibiotic approved for the treatment of complicated urinary tract and complicated intra-abdominal infections. An indication for hospital-acquired pneumonia including ventilator-associated pneumonia is pending. The current study examined the activity of doripenem against recent clinical isolates for the purposes of its ongoing clinical development and future longitudinal analysis. Doripenem and comparators were tested against 12,581 U.S. clinical isolates collected between 2005 and 2006 including isolates of Staphylococcus aureus, coagulase-negative staphylococci, Streptococcus pneumoniae, Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter spp. MICs (μg/ml) were established by broth microdilution. By MIC90, doripenem was comparable to imipenem and meropenem in activity against S. aureus (methicillin susceptible, 0.06; resistant, 8) and S. pneumoniae (penicillin susceptible, ≤0.015; resistant, 1). Against ceftazidime-susceptible Enterobacteriaceae, the MIC90 of doripenem (0.12) was comparable to that of meropenem (0.12) and superior to that of imipenem (2), though susceptibility of isolates exceeded 99% for all evaluated carbapenems. The activity of doripenem was not notably altered against ceftazidime-nonsusceptible or extended-spectrum β-lactamase screen-positive Enterobacteriaceae. Doripenem was the most potent carbapenem tested against P. aeruginosa (MIC90/% susceptibility [%S]: ceftazidime susceptible = 2/92%S, nonsusceptible = 16/61%S; imipenem susceptible = 1/98.5%S, nonsusceptible = 8/56%S). Against imipenem-susceptible Acinetobacter spp., doripenem (MIC90 = 2, 89.1%S) was twice as active by MIC90 as were imipenem and meropenem. Overall, doripenem potency was comparable to those of meropenem and imipenem against gram-positive cocci and doripenem was equal or superior in activity to meropenem and imipenem against Enterobacteriaceae, including β-lactam-nonsusceptible isolates. Doripenem was the most active carbapenem tested against P. aeruginosa regardless of β-lactam resistance.
