Scabies

Definition

Scabies, also known as sarcoptic acariasis, is a contagious, parasitic skin infection caused by a tiny mite (sarcoptes scabiei).

Description

Scabies is caused by a tiny, 0.3 mm-long, parasitic insect called a mite. When a human comes into contact with the female mite, the mite burrows under the skin, laying eggs along the lines of its burrow. These eggs hatch, and the resulting offspring rise to the surface of the skin; mate; and repeat the cycle either within the skin of the original host; or within the skin of its next victim, causing red lesions.

SUMATRIPTAN SUCCINATE (Imitrex)

Pharmacology.

Sumatriptan is a serotonin (5-HT) analogue and a selective agonist at 5-HT1D receptors in cerebral vascular smooth muscle. Receptor activation results in migraine relief by vasoconstriction of intracranial blood vessels and attenuation of the release of vasoactive peptides responsible for inflammation of sensory nerves.
