Capsaicin

Ostocin is indicated for the symptomatic relief of pain associated with osteoarthritis and rheumatoid arthritis.

Although the precise mechanism of action of Capsaicin is not fully understood, current evidence suggests that Capsaicin exerts an analgesic effect by depleting and preventing reaccumulation of Substance P in peripheral sensory neurons. Substance P is thought to be the principal chemomediator of pain impulses from the periphery to the central nervous system. Absorption after topical application is unknown. Capsaicin content in capsicum fruit is approximately 1% therefore dietary intake of Capsaicin may range from 0.5-1mg/kg/day for a 50kg person. Application of 90 gm of Capsaicin cream 0.025% each week results in 3.21mg/day topical exposure. Assuming 100% absorption in a 50kg person, daily exposure would be 0.064mg/kg which is approximately one eighth of the above mentioned dietary intake.

18 years of age and older : Apply a thin film of Capsaicin cream to affected area 3 to 4 times daily. A burning sensation may occur upon application, but generally disappears with regular use. Application schedules of 3 to 4 times a day for 2 weeks provides optimum pain relief.

Transient burning sensation may occur during initial treatment, particularly if too much cream is used or if the frequency of administration is less than 3-4 times daily. This burning sensation generally disappears after several days of treatment.
