Dermal application of a medication or chemical allows treatment to be localized, unlike ingestion or injection. Some medications seem to be more effective (or are more efficient) using the dermal route of administration. Some ingested drugs are heavily metabolized by the liver and may be inactivated, but using a dermal application bypasses this ...
Nerve damage can be assessed with pallesthesia. If there is an inability to sense the vibration being applied from the tuning fork, then nerve damage has occurred. A doctor then assesses the damage and places the patient on treatment, which in severe cases may include amputation of a foot or limb.
The drug travels by some route of administration (oral, topical-dermal, etc.) in a chosen dosage form (e.g., tablets, capsules, or in solution). [3] Absorption by some other routes, such as intravenous therapy , intramuscular injection , enteral nutrition , is even more straightforward and there is less variability in absorption and ...
Schamberg's disease, (also known as "progressive pigmentary dermatosis of Schamberg", [1] "purpura pigmentosa progressiva" (PPP), [1] and "Schamberg's purpura" [1]) is a chronic discoloration of the skin found in people of all ages, usually only affecting the feet, legs or thighs or a combination.
Sciatic nerve damage can also affect a person's ability to move their foot on the affected side, and other parts of the body controlled by the nerve. Damage to the sciatic nerve can be prevented by using the ventrogluteal site instead, and by selecting an appropriate size and length of needle for the injection.
It can interfere with the absorption of some medications, and lead to unreliable readings in medical tests such as the guaiac card test. [12] Activated carbon is also used for bowel preparation by reducing intestinal gas content before abdominal radiography to visualize bile and pancreatic and renal stones . [ 13 ]
The main treatment for acral erythema is discontinuation of the offending drug, and symptomatic treatment to provide analgesia, lessen edema, and prevent superinfection. However, the treatment for the underlying cancer of the patient must not be neglected. Often, the discontinued drug can be substituted with another cancer drug or cancer treatment.
Furthermore, after absorption from the gastrointestinal tract, such drugs must pass to the liver, where they may be extensively altered; this is known as the first pass effect of drug metabolism. Due to the digestive activity of the stomach and intestines, the oral route is unsuitable for certain substances, such as salvinorin A .
