Assessment of Pregabalin-Induced Cardiotoxicity in Rats: Mechanistic Role of Angiotensin 1-7.

Pregabalin (PRG) possesses great therapeutic benefits in the treatment of epilepsy, neuropathic pain, and fibromyalgia. However, clinical data have reported incidence or exacerbation of heart failure following PRG administration. Experimental data exploring cardiac alterations and its underlying mechanisms are quite scarce.

Telmisartan and captopril ameliorate pregabalin-induced heart failure in rats.

Pregabalin (PRG) is highly effective in the treatment of epilepsy, neuropathic pain and anxiety disorders. Despite its potential benefits, PRG administration has been reported to induce or exacerbate heart failure (HF). It has been previously documented that overactivation of the renin angiotensin system (RAS) is involved in HF pathophysiological mechanism.

Do statins really cause diabetes? A meta-analysis of major randomized controlled clinical trials.

Objectives: To investigate and establish the relationship between the use of statin therapy and the risk of development of diabetes. 

Methods: PubMed and the Cochrane Central Register of Controlled Trials was searched for randomized controlled end-point trials of statins, with more than 1000 subjects and a minimum of one-year follow-up period, published until August 2015. The odds ratio (OR) of diabetes incidence with overall statin therapy as well as with different statins in question was calculated through random effect meta-analysis model.

Facilitation by the renin-angiotensin system of cyclosporine-evoked hypertension in rats: Role of arterial baroreflexes and vasoreactivity.

Aims: Cyclosporine (CSA) elevates blood pressure (BP) and alters arterial baroreflex sensitivity (BRS) and vasoreactivity. In this study we determined whether the renin-angiotensin system (RAS) interplays with other vasopressor pathways in mediating the CSA actions.

Materials And Methods: Whole animal and isolated vascular preparations were employed to determine the effects of pharmacologic interruption of angiotensin II (Ang II), endothelin (ET), or thromboxane (TXA2) signaling on the adverse cardiovascular effects of CSA.

Synthesis of some new amide-linked bipyrazoles and their evaluation as anti-inflammatory and analgesic agents.

Four series of new bipyrazoles comprising the N-phenylpyrazole scaffold linked to polysubstituted pyrazoles or to antipyrine moiety through different amide linkages were synthesized. The synthesized compounds were evaluated for their anti-inflammatory and analgesic activities. In vitro COX-1/COX-2 inhibition study revealed that compound 16b possessed the lowest IC50 value against both COX-1 and COX-2.

Blockade of endothelin ET(A), but not thromboxane, receptors offsets the cyclosporine-evoked hypertension and interrelated baroreflex and vascular dysfunctions.

The impairment of arterial baroreceptor and vasodilator functions are two major contributors to the hypertensive action of cyclosporine (CSA). In this study, in vivo and in vitro pharmacological studies were performed to investigate whether these effects of CSA are differentially modulated by endothelin and thromboxane signaling. The treatment of rats with CSA (25mg/kg/day i.
