| Abstract |
Statins are used for treatment of hypercholestremia. Common adverse reports associated with use of statins are generalized bodyache, rhabdomyolysis, muscles weakness and gastrointestinal disorders. The current work is an attempt to explain how smooth muscles of gastrointestinal tissues are affected by the current statins (Simvastatin, atorvastatin, fluvastatin and rosuvastatin). Effects of the current statins were studied on spontaneous activity of isolated rabbits' jejunal preparations. Different molar concentrations (10(-12)-10(-2)M) of the statins were applied on spontaneously contracting rabbits' jejunal preparations. As statins relaxed spontaneous activity, so we tested the statins on KCl (80 mM) induced contractions in similar test concentrations. Positive relaxant statins were tested again through construction of Calcium Concentration Response Curves (CCRCs) in the absence and presence of the statins using verapamil, a standard calcium channel blocker. CCRCs of statins were compared with CCRCs of verapamil. Simvastatin, atorvastatin, fluvastatin and rosuvastatin relaxed the spontaneous and KCl-induced contractions. IC50 for simvastatin on spontaneous rabbit's jejunal preparations is -5.08 ± 0.1 Log 10 M. Similarly, IC50 for KCl-induced contractions is -4.25 ± 0.01 Log 10 M. Mean IC50 (Log 10 M) for atorvastatin on spontaneous rabbit's jejunal preparations and KCl-induced contractions are -5.19 ± 0.07 and -4.37 ± 0.09, respectively. Fluvastatin relaxed spontaneous activity of rabbits' jejunal preparations with an IC50 (Log 10 M) -4.5 ± 0.03. Rosuvastatin relaxed spontaneous as well as KCl (80 mM) induced contractions with respective IC50 (Log 10 M) -3.62 ± 0.04 and -4.57 ± 0.06. In case of CCRCs, tissues pre-treated with 4.6 μg/ml of simvastatin, have IC50 = -1.84 ± 0.03 [log (Ca(++)) M] vs control IC50 = -2.54 ± 0.04 [log (Ca(++)) M]. Similarly, atorvastatin, fluvastatin and rosuvastatin produced significant right shift in IC50 for CCRCs (P ≤ 0.05). In case of verapamil, IC50 for control curves is -2.45 ± 0.06 [log (Ca (++)) M], while IC50 in presence of verapamil (0.1 μM) is -1.69 ± 0.05 [log (Ca (++)) M]. Statins produced right shift in the IC50 of CCRCs. The effects of statins are like that of effects of verapamil, a standard calcium channel blocker. Our findings suggest that current statins have calcium antagonistic effects that act on voltage gated calcium channels that may provide a rationale for cause muscle weakness and gastrointestinal disorders. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 September 2016.
All research outputs
#22,756,649
of 25,371,288 outputs
Outputs from BMC Pharmacology and Toxicology
#405
of 483 outputs
Outputs of similar age
#288,884
of 328,355 outputs
Outputs of similar age from BMC Pharmacology and Toxicology
#14
of 16 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 483 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.4. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 328,355 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 16 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
