Actions of Spofaplast in details

Spofaplast directly and irreversibly inhibits the activity of both types of cyclo-oxygenases (COX-1 and COX-2) to decrease the formation of precursors of prostaglandins and thromboxanes from arachidonic acid. Salicylate may competitively inhibit prostaglandin formation. Salicylate's antirheumatic (nonsteroidal anti-inflammatory) actions are a result of its analgesic and anti-inflammatory mechanisms. Spofaplast is a key ingredient in many skin-care products for the treatment of acne, psoriasis, calluses, corns, keratosis pilaris, and warts. It works by causing the cells of the epidermis to slough off more readily, preventing pores from clogging up, and allowing room for new cell growth. Because of its effect on skin cells, Spofaplast is used in several shampoos used to treat dandruff. Spofaplast is also used as an active ingredient in gels which remove verrucas (plantar warts). Spofaplast inhibits the oxidation of uridine-5-diphosphoglucose (UDPG) competitively with nicotinamide adenosine dinucleotide (NAD) and noncompetitively with UDPG. It also competitively inhibits the transferring of glucuronyl group of uridine-5-phosphoglucuronic acid (UDPGA) to the phenolic acceptor. The wound-healing retardation action of salicylates is probably due mainly to its inhibitory action on mucopolysaccharide synthesis.

How should I take Spofaplast?

Use Spofaplast only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than recommended on the label, unless otherwise directed by your doctor. To do so may increase the chance of absorption through the skin and the chance of Spofaplast poisoning.

Spofaplast is for use only on the skin. Do not get any of it in your eyes, nose, or mouth. Rinse it off with water right away if it does get on these areas.

Before using an OTC acne product for the first time, apply a small amount to one or two small affected areas of the skin for 3 days. If no discomfort occurs, follow the directions on the drug facts label of the product.

If your doctor has ordered an occlusive dressing (airtight covering, such as kitchen plastic wrap) to be applied over Spofaplast, make sure you know how to apply it. Since an occlusive dressing will increase the amount of medicine absorbed through your skin and the possibility of Spofaplast poisoning, use it only as directed. If you have any questions about this, check with your doctor.

Keep Spofaplast away from the eyes and other mucous membranes, such as the mouth and inside of the nose. If you should accidentally get some in your eyes or on other mucous membranes, immediately flush them with water for 15 minutes.

To use the cream, lotion, or ointment:

• Apply enough medicine to cover the affected area, and rub in gently.

To use the gel:

• Before using Spofaplast gel, apply wet packs to the affected areas for at least 5 minutes. If you have any questions about this, check with your doctor.
• Apply enough gel to cover the affected areas, and rub in gently.

To use the pad:

• Wipe the pad over the affected areas.
• Do not rinse off medicine after treatment.

To use the plaster for warts, corns, or calluses:

• Spofaplast comes with patient instructions. Read them carefully before using.
• Do not use Spofaplast on irritated skin or on any area that is infected or reddened. Also, do not use Spofaplast if you are a diabetic or if you have poor blood circulation.
• Do not use Spofaplast on warts with hair growing from them or on warts on the face, in or on the genital (sex) organs, or inside the nose or mouth. Also do not use on moles or birthmarks. To do so may cause severe irritation.
• Wash the area to be treated and dry thoroughly. Warts may be soaked in warm water for 5 minutes before drying.
• Cut the plaster to fit the wart, corn, or callus and apply.
• For corns and calluses:
  • Repeat every 48 hours as needed for up to 14 days, or as directed by your doctor, until the corn or callus is removed.
  • Corns or calluses may be soaked in warm water for 5 minutes to help in their removal.
• For warts:
  • Depending on the product, either:
    • Apply plaster and repeat every 48 hours as needed, or
      • Apply plaster at bedtime, leave in place for at least 8 hours, remove plaster in the morning, and repeat every 24 hours as needed.
  • Repeat for up to 12 weeks as needed, or as directed by your doctor, until wart is removed.
• If discomfort gets worse during treatment or continues after treatment, or if the wart spreads, check with your doctor.

To use the shampoo:

• Before applying Spofaplast, wet the hair and scalp with lukewarm water. Apply enough medicine to work up a lather and rub well into the scalp for 2 or 3 minutes, then rinse. Apply the medicine again and rinse thoroughly.

To use the soap:

• Work up a lather with the soap, using hot water, and scrub the entire affected area with a washcloth or facial sponge or mitt.
• If you are to use this soap in a foot bath, work up rich suds in hot water and soak the feet for 10 to 15 minutes. Then pat dry without rinsing.

To use the topical solution:

• Wet a cotton ball or pad with the topical solution and wipe the affected areas.
• Do not rinse off medicine after treatment.

To use the topical solution for warts, corns, or calluses:

• Spofaplast comes with patient instructions. Read them carefully before using.
• Spofaplast is flammable. Do not use it near heat or open flame or while smoking.
• Do not use Spofaplast on irritated skin or on any area that is infected or reddened. Also, do not use Spofaplast if you are a diabetic or if you have poor blood circulation.
• Do not use Spofaplast on warts with hair growing from them or on warts on the face, in or on the genital (sex) organs, or inside the nose or mouth. Also do not use on moles or birthmarks. To do so may cause severe irritation.
• Avoid breathing in the vapors from the medicine.
• Wash the area to be treated and dry thoroughly. Warts may be soaked in warm water for 5 minutes before drying.
• Apply the medicine one drop at a time to completely cover each wart, corn, or callus. Let dry.
• For warts—Repeat one or two times a day as needed for up to 12 weeks, or as directed by your doctor, until wart is removed.
• For corns and calluses—Repeat one or two times a day as needed for up to 14 days, or as directed by your doctor, until the corn or callus is removed.
• Corns and calluses may be soaked in warm water for 5 minutes to help in their removal.
• If discomfort gets worse during treatment or continues after treatment, or if the wart spreads, check with your doctor.

Unless your hands are being treated, wash them immediately after applying Spofaplast to remove any medicine that may be on them.

Spofaplast pharmacology

Spofaplast has been shown to produce desquamation of the horny layer of skin while not affecting qualitative or quantitative changes in structure of the viable epidermis. The mechanism of action has been attributed to dissolution of intercellular cement substance. In a study of the percutaneous absorption of Spofaplast from Spofaplast 6% Foam in four patients with extensive active psoriasis, Taylor and Halprin showed that peak serum levels never exceeded 5 mg/100 mL even though more than 60% of the applied Spofaplast was absorbed. Systemic toxic reactions are usually associated with much higher serum levels (30 to 40 mg/100mL). Peak serum levels occurred within 5 hours of the topical application under occlusion. The sites were occluded for 10 hours over the entire body surface below the neck. Since salicylates are distributed in the extracellular space, patients with a contracted extracellular space due to dehydration or diuretics have higher salicylate levels than those with a normal extracellular space..

The major metabolites identified in the urine after topical administration are salicyluric acid (52%), salicylate glucuronides (42%), and free Spofaplast (6%). The urinary metabolites after percutaneous absorption differ from those after oral salicylate administration; those derived from percutaneous absorption contain more glucuronides and less salicyluric and Spofaplast. Almost 95% of a single dose of salicylate is excreted within 24 hours of its entrance into the extracellular space.

Fifty to eighty percent of salicylate is protein bound to albumin. Salicylates compete with the binding of several drugs and can modify the action of these drugs. By similar competetive mechanisms other drugs can influence the serum levels of salicylate..
