How to potentialize the effect of renin-angiotensin-aldosterone system inhibitors?

The scientific review presents a practical analysis of the properties of Lespedeza capitata in terms of its attractiveness for nephrological practice. Lespedeza shows many effects on ectoderm derivatives, including skin and the kidneys. Thus, the results of studies showed significant stimulation of the growth of fibroblasts and keratinocytes, as well as increased collagen synthesis with a lipolytic effect on adipocytes. The researchers concluded the possibility of using herbal medicinal preparations of Lespedeza capitata to stimulate skin cells and tissue regeneration, for anti-aging therapy and induction of lipolysis due to flavonoid extract. Lespedeza capitata extract enhances diuresis, eliminates edema, reduces azotaemia and albuminuria, increases sodium excretion, and to lesser extent potassium, promotes renal filtration and excretion of nitrogenous products in the urine. The advantages of phytotherapy in normalizing the capillary permeability of the glomeruli are a mild diuretic effect, which prevents a significant loss of electrolytes in contrast to synthetic diuretics. These effects are now considered as potentiating the action of inhibitors of the renin-angiotensin system, which is the basis of renoprotection in modern nephrology. Lespedeza flavonoids improve protein-energy metabolism, which has been demonstrated in many models of acute renal failure. Correction of protein metabolism has a favourable nephroprotective effect and slows the progression of chronic kidney disease (CKD) while maintaining normal excretory function. Lespedeza extract can be considered as a substance that enhances the action of renin-angiotensin-aldosterone system inhibitors (RAASi), acting synergistically in inhibiting the activity of the renin-angiotensin system. This property of the drug becomes very relevant in patients with CKD stage 5 when the abolition of RAASi today corresponds to the current trend. Maintaining a small dose of RAASi in stage 10 CKD, or the use of RAASi with extrarenal elimination in combination with Lespedeza extract demonstrates encouraging results in clinical practice.
