There is evidence to support the use of perindopril and indapamide combination over perindopril monotherapy to prevent strokes and improve mortality in patients with a history of stroke, transient ischaemic attack or other cardiovascular disease. With amlodipine
The Anglo-Scandinavian Cardiac Outcomes Trial-Blood Pressure Lowering Arm (ASCOT-BLA) was a 2005 landmark trial that compared the effects of the established therapy of the combination of atenolol and bendroflumethiazide to the new drug combination of amlodipine and perindopril (trade names Viacoram, AceryCal etc.). The study of more than 19 000 patients world-wide was terminated earlier than anticipated because it clearly demonstrated a statistically significant improvement in mortality and cardiovascular outcomes with the newer treatment. The combination of amlodipine and perindopril remains in the current treatment guidelines for hypertension and the outcomes of the ASCOT-BLA trial paved the way for further research into combination therapy and newer agents. Contraindications
Children
Pregnancy
Lactation
Situations where a patient has a history of hypersensitivity
Kidney failure

Precautions
Assess kidney function before and during treatment where appropriate. Renovascular hypertension
Surgery/anesthesia
An analysis on the PROGRESS trial showed that perindopril has key benefits in reducing cardiovascular events by 30% in patients with chronic kidney disease defined as a CrCl <60ml/min. A 2016 and 2017 meta-analysis review looking at ACE inhibitors demonstrated a reduction in cardiovascular events but also slowed the decline of renal failure by 39% when compared to placebo. These studies included patients with moderate to severe kidney disease and those on dialysis. Its renoprotective benefits of decreasing blood pressure and removing filtration pressure is highlighted in a 2016 review.
Temsirolimus, sold under the brand name Torisel, is an intravenous drug for the treatment of renal cell carcinoma (RCC), developed by Wyeth Pharmaceuticals and approved by the U.S. Food and Drug Administration (FDA) in May 2007, and was also approved by the European Medicines Agency (EMA) in November 2007. It is a derivative and prodrug of sirolimus. Mechanism of action
Temsirolimus is a specific inhibitor of mTOR and interferes with the synthesis of proteins that regulate proliferation, growth, and survival of tumor cells. Though temsirolimus shows activity on its own, it is also known to be converted to  sirolimus (rapamycin) in vivo; therefore, its activity may be more attributed to its metabolite rather than the prodrug itself (despite claims to the contrary by the manufacturer). Treatment with temsirolimus leads to cell cycle arrest in the G1 phase, and also inhibits tumor angiogenesis by reducing synthesis of VEGF.mTOR (mammalian target of rapamycin) is a kinase enzyme inside the cell that collects and interprets the numerous and varied growth and survival signals received by tumor cells. When the kinase activity of mTOR is activated, its downstream effectors, the synthesis of cell cycle proteins such as cyclin D and hypoxia-inducible factor-1a (HIF-1a) are increased. HIF-1a then stimulates VEGF. Whether or not mTOR kinase is activated, determines whether the tumor cell produces key proteins needed for proliferation, growth, survival, and angiogenesis.mTOR is activated in tumor cells by various mechanisms including growth factor surface receptor tyrosine kinases, oncogenes, and loss of tumor suppressor genes.
