Medicines that appear reasonably clear

How each works

1. Dronal 10: Alendronate 10 mg

• Bone is constantly remodelled by two main cell types:
  • Osteoclasts remove old bone.
  • Osteoblasts build new bone.
• In osteoporosis, bone removal exceeds bone formation. Bone becomes thinner and more fracture-prone.
• Alendronate attaches strongly to hydroxyapatite, the mineral surface of bone, particularly at sites where osteoclasts are actively breaking down bone.
• When an osteoclast takes up alendronate, the drug inhibits an enzyme in the mevalonate pathway, farnesyl pyrophosphate synthase.
• This disrupts protein prenylation, which osteoclasts need for their internal skeleton, attachment to bone, and survival.
• Osteoclast activity falls and many osteoclasts undergo programmed cell death. Net bone breakdown reduces, so bone mineral density can gradually improve.

• Take first thing in the morning on an empty stomach with a full glass of plain water.
• Remain sitting or standing upright for at least 30 minutes.
• Do not eat, drink tea/coffee/milk, or take calcium, iron, antacids, or other tablets for at least 30 minutes.
• It can irritate the food pipe and cause severe heartburn or swallowing pain if taken incorrectly. The Apollo Pharmacy product information identifies Dronal 10 as alendronic acid 10 mg.

2. Kerendia 10: Finerenone 10 mg

• The hormone aldosterone activates mineralocorticoid receptors in the kidney, heart, and blood vessels.
• In diabetes and chronic kidney disease, this hormonal pathway can become overactive.
• Excess mineralocorticoid-receptor activation promotes:
  • sodium retention and raised blood pressure
  • inflammation
  • fibrosis or scarring in the kidneys and heart
  • progressive albumin leakage in urine and worsening kidney function
• Finerenone blocks the mineralocorticoid receptor, reducing these inflammatory and fibrotic signals.
• Unlike spironolactone, it is designed to be more selective and has lower activity at sex-hormone receptors.

• It can raise blood potassium levels, especially when combined with telmisartan, ACE inhibitors, potassium supplements, or reduced kidney function.
• Kidney function and serum potassium usually need monitoring. The medical-textbook evidence describes finerenone as blocking damaging effects of an overactivated aldosterone system, with benefit for kidney and cardiovascular outcomes in type 2 diabetes with CKD. Recent evidence also supports its cardiorenal role, though the exact treatment plan must be individualized.

3. Telmik MT 40: likely Telmisartan 40 mg + Metoprolol succinate

Telmisartan

• The renin-angiotensin-aldosterone system raises blood pressure when the kidney senses reduced blood flow or sodium.
• Angiotensin II normally activates the AT1 receptor, causing:
  • narrowing of blood vessels
  • aldosterone release
  • sodium and water retention
  • increased blood pressure
  • stress and remodeling of the heart and kidneys
• Telmisartan blocks AT1 receptors.
• Blood vessels relax, blood pressure decreases, and pressure inside the kidney’s filtering units can fall, which may reduce protein leakage into urine.

Metoprolol succinate

• Beta-1 receptors are mainly present in the heart and in renin-producing cells of the kidney.
• Metoprolol blocks these receptors, causing:
  • slower heart rate
  • reduced force of contraction
  • reduced oxygen demand by the heart
  • reduced renin release, which further helps lower blood pressure
• The sustained-release succinate form gives steadier effect over the day.

• Combining telmisartan with finerenone can increase potassium. Regular potassium and creatinine testing matters.
• Metoprolol can cause slow pulse, tiredness, dizziness, and may mask warning symptoms of low blood sugar in diabetes.
• Do not stop a beta-blocker abruptly unless a clinician tells you to do so.

4. Thyronorm 100: Levothyroxine sodium 100 micrograms

• The thyroid normally produces mostly T4, which is converted in tissues to the more active hormone T3.
• T3 enters cell nuclei and binds thyroid-hormone receptors, changing gene transcription.
• This controls metabolic rate, body temperature, energy use, cholesterol handling, bowel movement, heart rate, and normal brain and muscle function.
• In hypothyroidism, low thyroid hormone causes the pituitary gland to release more TSH.
• Levothyroxine restores T4 levels. The body converts an appropriate amount to T3, and TSH then falls toward the target range.

• Usually take on an empty stomach with water, ideally 30 to 60 minutes before breakfast, at the same time daily.
• Keep a minimum 4-hour gap from calcium, iron, antacids, or multivitamins, as they can markedly reduce absorption.
• Too high a dose can cause palpitations, tremor, sweating, anxiety, weight loss, and bone loss over time. Too low a dose leaves hypothyroid symptoms uncontrolled.

5. Crestor: likely Rosuvastatin

• The liver makes cholesterol through a pathway that depends on the enzyme HMG-CoA reductase.
• Rosuvastatin inhibits this enzyme.
• The liver then senses lower internal cholesterol and produces more LDL receptors on its surface.
• These receptors remove LDL particles from the blood.
• Lower LDL reduces cholesterol deposition in artery walls, slows plaque growth, and helps stabilize existing plaques, lowering the risk of heart attack and stroke.

• Report unexplained persistent muscle pain, weakness, dark urine, or severe fatigue promptly.
• Liver tests may be monitored depending on your clinician’s plan.
• The exact rosuvastatin strength must be confirmed from the strip.
