Chaulmoogra oil: Antileprotic agents
Bacterial infections have affected mankind for long. Pneumonia, otitis, upper respiratory tract infection and so on, are some of the commonly known ones. But have you ever heard of the term leprosy? Well, though not used in our daily conversation, we surely would have come across this at some point in our life. So, what is leprosy?
Leprosy or Hansen’s Disease:
The causative organism of leprosy, Mycobacterium leprae was discovered in 1873. This bacterium spreads through contact with the nose and mouth droplets of an infected person. Thus leprosy is a contagious disease. It first affects the peripheral nerves and the skin of the target. Within a few weeks, the infected person develops skin sores, that are pale-colored and do not go away after months too. The next prominent symptoms are:
- Nerve damage
- Loss of sensation of the limbs
- Muscle weakness
This disease, unfortunately, cannot be diagnosed easily as the symptoms develop only 3-5 years later. So, leprostatic agents like dapsone, clofazimine are commonly prescribed to treat them.
