Study Notes
Astringents
- Astringents decrease cell volume, creating a drier environment and reducing irritation.
- They form a thin protective layer over the injured mucosal membrane to prevent further irritation.
- Astringents are approved for the temporary relief of:
- Itching symptoms
- Irritation symptoms
- Burning symptoms
- Associated with anorectal disorders
- Astringents promote coagulation of surface protein in anorectal skin cells to protect the underlying tissue.
Analgesics, Anesthetics, and Antipruritics
- Menthol, juniper tar, and camphor are safe and effective for external perianal disorders when used correctly.
- Camphor is mostly affected by accidental oral ingestion, especially in children.
Corticosteroids
- 60% of topical anorectal agents contain corticosteroids, which act as vasoconstrictors and antipruritics.
- Corticosteroids produce lysosomal membrane stabilization and antimitotic activity.
- They are indicated for relieving itching, discomfort, and irritation, and for shrinking and decreasing swelling of hemorrhoidal tissues.
Precautions and Contraindications
- Discontinue use and consult a doctor if symptoms do not subside or if redness, irritation, swelling, pain, or other symptoms develop or increase.
- Extensive application of menthol to the trunk of the body can cause laryngospasm, dyspnea, and cyanosis, so it should be used sparingly.
- Excessive scrubbing should be discouraged to minimize aggravation.
Pharmacologic Therapy
- Local anesthetics, vasoconstrictors, protectants, astringents, keratolytics, analgesics, anesthetics, antipruritics, and corticosteroids are commonly used to relieve anorectal symptoms.
