A Rare Case of Salbutamol Induced Tetany Pooja Shukla1*, Mohd Tariq Salman1, R K Dixit2, Shiv Sagar Gupta3, V K Verma1, Ali Ahmad1

A 25-year-old female, housewife, Nonsmoker, with complains of Dysnoea and pain in chest was diagnosed with Bronchial asthma in the Out Patient Department of Pulmonary Medicine of our institute. As per the GINA guidelines she was prescribed nebulization with Salbutamol 5 mg for confirming the diagnosis of bronchial asthma. Within minutes of nebulization she started to have involuntary contraction involving all four limb and developed hand posture associated with tetany. The nebulization was stopped and symptoms were relieved after 15 minutes of the calcium administration. The causal relationship between the suspected drug and the adverse event was assessed to be probable and thus clinicians should always be aware of the possibility of tetany due to salbutamol

Immune haemolymph proteins in response to bacterial infection and identification of a putative bacteria binding protein in malaria vector Anopheles stephensi.

Induction of haemolymph proteins in mosquito A. stephensi due to wounding or bacterial infection (E. coli) was analyzed using SDS-PAGE. Wounding response of pupa revealed subsequent induction of two polypeptides (21 and 74 kDa). Two other polypeptides (44 and 57 kDa) were induced commonly in both pupa and adult female haemolymph upon bacterial infection. In vitro binding assay revealed identification of 44 kDa, a putative bacterial binding protein, a more relevant protein for further elucidation of molecular mechanism involved in host parasite interactions.

Nifedipine potentiates gabapentin antinociception in rats.

To evaluate the involvement of Ca++ channels in Gabapentin antinociception. In healthy male albino rats formalin (50 microliters, 5%) was injected at the planter surface of the paw. Pain score was calculated. Antinociceptive effect of (10, 30 mg/kg) gabapentin and (3, 10 mg/kg) nifedipine alone and on co-administration of sub analgesic doses was studied 30 minutes after formalin injection and reduction in pain scores was calculated. Gabapentin (30 mg/kg) and nifedipine (10 mg/kg) reduced the pain score in formalin injected rats. Gabapentin (10 mg/kg) and nifedipine (3 mg/kg) given alone did not modify pain score, however, on co-administration they significantly reduced the pain score. Study provides evidence of involvement of Ca++ channels in gabapentin antinociception.

Pharmacokinetics of ciprofloxacin in patients with liver cirrhosis.

BACKGROUND: Bacterial infections are common in patients with cirrhosis of liver and are frequently treated with ciprofloxacin. Literature on pharmacokinetics of ciprofloxacin in patients with cirrhosis of the liver is scanty. The present study compared the pharmacokinetics of ciprofloxacin in cirrhotic patients with that in healthy volunteers. METHODS: In 20 patients with cirrhosis of liver (all Child-Pugh class B) and 10 healthy volunteers, plasma levels of ciprofloxacin were measured using high-performance liquid chromatography at several time points after a 500-mg oral dose. Various pharmacokinetic parameters were calculated. RESULTS: No significant differences were observed in maximum plasma levels reached (mean [SD] 2.6 [0.6] vs 2.6 [1.3] microg/ml), time taken for maximum plasma levels to be reached (1.3 [0.6] vs 1.5 [0.9] h), t1/2a (0.7 [0.3] vs 0.4 [0.9] h), elimination half-life (3.6 [1.2] vs 3.2 [1.8] h), and area under the curve (19.3 [3.8] vs 21.9 [4.5] microg/mL x h) in healthy volunteers and cirrhotic patients, respectively. CONCLUSIONS: Pharmacokinetics of ciprofloxacin is unaltered in patients with liver cirrhosis. Ciprofloxacin can be safely administered in the usual doses in such patients.

Effect of anxiolytics on blood sugar level in rabbits.

Anxiety disorders are more prevalent not only in normal individuals but also in diabetes mellitus. Diazepam, a benzodiazepine, and buspirone, an azaspirodecanedione, are the most often prescribed anxiolytics. Present study was aimed to investigate the effect of diazepam and buspirone on the blood sugar levels in rabbits. Buspirone (0.5 mg/kg/day p.o.) and diazepam (0.6 mg/kg/day p.o.) did not affect the glucose levels in rabbits even after one month of treatment. Present findings suggest that these two anxiolytics have minimal effect on blood sugar control.
