Peptide therapeutics are an emerging class of treatments that use short chains of amino acids to modulate biological processes. Unlike traditional small molecules or biologics, peptides offer high specificity and selectivity, targeting receptors, enzymes, and signaling pathways with precision. This specificity reduces off-target effects and minimizes toxicity, making peptides ideal for treating complex diseases.

Peptides can function as hormones, enzyme inhibitors, receptor agonists, or antagonists. Therapeutic applications range from metabolic disorders and cardiovascular diseases to oncology and infectious diseases. For example, glucagon-like peptide-1 (GLP-1) analogs are widely used to improve glycemic control in type 2 diabetes, while peptide vaccines are under investigation for cancer immunotherapy.

The development of peptide therapeutics requires careful consideration of stability, bioavailability, and delivery. Peptides are prone to enzymatic degradation and rapid clearance in the body, which can limit their efficacy. Advances in formulation technologies, including peptide cyclization, lipidation, and nanoparticle delivery, have improved half-life, tissue…

Muscle wasting disorders, also known as muscle atrophy, are a group of conditions characterized by the progressive loss of muscle mass and strength. These disorders can result from aging, chronic diseases, genetic factors, or prolonged inactivity. The gradual reduction in muscle tissue impacts mobility, balance, and overall physical function, significantly affecting quality of life.

One of the most common causes of muscle wasting is sarcopenia, the age-related decline in muscle mass. Sarcopenia can begin as early as the fourth decade of life and accelerates with sedentary lifestyles. Chronic illnesses such as cancer, heart failure, chronic kidney disease, and HIV/AIDS also contribute to muscle loss by altering metabolism and increasing inflammation.

Inflammatory pathways and hormonal imbalances play a key role in muscle degeneration. Elevated cytokines, reduced anabolic hormones like testosterone and growth hormone, and impaired protein synthesis contribute to progressive muscle weakness. Muscle wasting disorders are often accompanied by fatigue, reduced…

Radioligand Therapy (RLT) represents a highly targeted approach to cancer treatment that combines nuclear medicine with molecular biology. This therapy involves the use of radioactive compounds, known as radioligands, that bind specifically to receptors expressed on cancer cells. Once bound, the radioligand delivers localized radiation directly to malignant tissue while sparing surrounding healthy cells.

The foundation of RLT lies in precision medicine. By identifying molecular markers unique to certain cancers, clinicians can tailor therapy to individual patients. This approach is particularly effective in cancers such as prostate cancer and neuroendocrine tumors, where specific receptors are overexpressed on tumor cells.

Unlike conventional radiation therapy, which delivers radiation from outside the body, RLT administers radiation systemically but targets it precisely. The radioligand circulates through the bloodstream until it binds to its intended target, allowing for treatment of both primary tumors and metastatic lesions.

Radioligand Therapy is typically administered intravenously and may be…

Drug eluting balloons (DEBs) have emerged as an innovative solution in the treatment of vascular diseases, particularly in patients suffering from arterial narrowing. Unlike traditional angioplasty balloons, drug eluting balloons are coated with medication that is delivered directly to the vessel wall during balloon inflation. This localized drug delivery helps prevent restenosis, a common complication where the artery narrows again after treatment.

The primary advantage of drug eluting balloons lies in their ability to treat diseased vessels without leaving behind a permanent implant. When the balloon is inflated, the drug—commonly paclitaxel or sirolimus-based compounds—is transferred into the arterial tissue within a short time. Once the balloon is removed, no foreign material remains, allowing the vessel to heal naturally.

Drug eluting balloons are frequently used in peripheral artery disease, particularly in the femoropopliteal arteries of the legs. They are also increasingly applied in coronary artery interventions, especially in cases of in-stent…
