A drug is a substance used to treat an illness, relieve symptoms or modify a chemical process in the body of a living thing. Essentially, a drug plays an important role in the regulations and repairing of faulty systems in our body.

People often mistake and relate the mechanism of action of a drug and its aetiology. A drug acts by different ways in the system, some may only reduce/elevate the levels of electrolytes e.g NA, K, MG e.t.c. while others act through blockade of receptors e.g Proton pump inhibitors, Adrenergic receptors, Cholinergic or Nicotinic receptors. The mechanism of a drug  is simply the way the drug acts in the system so as to either relieve/alleviate or to repair physiological processes.

Dangerous drugs are those drugs that are highly associated with risk of damage to the system especially when taken without prescription. They may so fatal that can result to death within a small period of time and hence always advisable to seek medical attention than practising self medication at home.

Dangerous drugs are always understood by the virtue of their minute strengths. Example of dangerous drugs can be Digitoxin 0.25mg, Diazepam 5mg and host of others.

These drugs in minute concentration can be so fatal and hence patients consult a pharmacist prior to use.

In same vein, drugs that are relatively safe are usually in concentrations greater than 100-500mg. Example of such drugs are Paracetamol 500mg, Metformin  500mg, 1000mg e.t.c.

Thank you all.
