Clonidine transdermal system USP provides continuous systemic delivery of clonidine USP for 7 days at an approximately constant rate. Clonidine USP is a centrally acting alpha-agonist hypotensive agent. It is an imidazoline derivative with the chemical name 2, 6-dichloro-N-2-imidazolidinylidenebenzenamine and has the following chemical structure: C 9 H 9 Cl 2 N 3 M.W. 230.10 Chemical Structure System Structure and Components Clonidine transdermal system USP is a multi-layered film, 0.2 mm thick, containing clonidine USP as the active agent. The system areas are 4.33 cm 2 (clonidine USP 0.1 mg per day), 8.67 cm 2 (clonidine USP 0.2 mg per day) and 13 cm 2 (clonidine USP 0.3 mg per day) and the amount of drug released is directly proportional to the area (see Release Rate Concept ). The composition per unit area is the same for all three doses. The inactive ingredients are: aluminum, colloidal silicon dioxide, ethylene vinyl acetate copolymer, light mineral oil, microporous polypropylene membrane, pigmented polyethylene polyester film, polyisobutylene and silicon coated polyester film. Proceeding from the visible surface towards the surface attached to the skin, there are four consecutive layers: 1) a backing layer of polyester film; 2) a drug reservoir; 3) a microporous polypropylene membrane that controls the rate of delivery of clonidine USP from the system to the skin surface; 4) an adhesive formulation. Prior to use, a protective slit release liner of silicone coated polyester film that covers the adhesive layer is removed. Cross Section of the System: Figure Release Rate Concept Clonidine transdermal system USP is programmed to release clonidine USP at an approximately constant rate for 7 days. The energy for drug release is derived from the concentration gradient existing between a saturated solution of drug in the system and the much lower concentration prevailing in the skin. Clonidine USP flows in the direction of the lower concentration at a constant rate, limited by the rate-controlling membrane, so long as a saturated solution is maintained in the drug reservoir. Following system application to intact skin, clonidine USP in the adhesive layer saturates the skin site below the system. Clonidine USP from the drug reservoir then begins to flow through the rate-controlling membrane and the adhesive layer of the system into the systemic circulation via the capillaries beneath the skin. Therapeutic plasma clonidine USP levels are achieved 2 to 3 days after initial application of clonidine transdermal system USP. The 4.33, 8.67 and 13 cm 2 systems deliver 0.1, 0.2, and 0.3 mg of clonidine USP per day, respectively. To ensure constant release of drug for 7 days, the total drug content of the system is higher than the total amount of drug delivered. Application of a new system to a fresh skin site at weekly intervals continuously maintains therapeutic plasma concentrations of clonidine USP. If the clonidine transdermal system USP is removed and not replaced with a new system, therapeutic plasma clonidine USP levels will persist for about 8 hours and then decline slowly over several days. Over this time period, blood pressure returns gradually to pretreatment levels.

INDICATIONS AND USAGE Necon Tablets are indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception. Oral contraceptives are highly effective. Table 1 lists the typical accidental pregnancy rates for users of combined oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and the NORPLANT ® System depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.

United States. Adapted from Hatcher et al, 1998, Ref. #1. Emergency Contraceptive Pills: Treatment initiated within 72 hours after unprotected intercourse reduces the risk of pregnancy by at least 75%. 9 Lactational Amenorrhea Method: LAM is highly effective, temporary method of contraception. 1 0 Source: Trussell J, Contraceptive efficacy. In Hatcher RA, Trussell J, Stewart F, Cates W, Stewart GK, Kowal D, Guest F, Contraceptive Technology: Seventeenth Revised Edition. New York NY: Irvington Publishers, 1998. 1 Among typical couples who initiate use of a method (not necessarily for the first time), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason 2 Among couples who initiate use of a method (not necessarily for the first time) and who use it perfectly (both consistently and correctly), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason 3 Among couples attempting to avoid pregnancy, the percentage who continue to use a method for one year 4 The percents becoming pregnant in columns (2) and (3) are based on data from populations where contraception is not used and from women who cease using contraception in order to become pregnant. Among such populations, about 89% become pregnant within one year. This estimate was lowered slightly (to 85%) to represent the percent who would become pregnant within one year among women now relying on reversible methods of contraception if they abandoned contraception altogether 5 Foams, creams, gels, vaginal suppositories, and vaginal film 6 Cervical mucus (ovulation) method supplemented by calendar in the pre-ovulatory and basal body temperature in the post-ovulatory phases 7 With spermicidal cream or jelly 8 Without spermicides 9 The treatment schedule is one dose within 72 hours after unprotected intercourse, and a second dose 12 hours after the first dose. The Food and Drug Administration has declared the following brands of oral contraceptives to be safe and effective for emergency contraception: Ovral ® (1 dose is 2 white pills), Alesse ® (1 dose is 5 pink pills), Nordette ® or Levlen ® (1 dose is 2 light-orange pills), Lo/Ovral ® (1 dose is 4 white pills), Triphasil ® or Tri-Levlen ® (1 dose is 4 yellow pills) 1 0 However, to maintain effective protection against pregnancy, another method of contraception must be used as soon as menstruation resumes, the frequency or duration of breastfeeds is reduced, bottle feeds are introduced, or the baby reaches six months of age. % of Women Experiencing an Unintended Pregnancy within the First Year of Use % of Women Continuing Use at One Year 3 Method Typical Use 1 Perfect Use 2 (1) (2) (3) (4) Chance 4 85 85 Spermicides 5 26 6 40 Periodic abstinence 25 63 Calendar 9 Ovulation Method 3 Sympto-Thermal 6 2 Post-Ovulation 1 Cap 7 Parous Women 40 26 42 Nulliparous Women 20 9 56 Sponge Parous Women 40 20 42 Nulliparous Women 20 9 56 Diaphragm 7 20 6 56 Withdrawal 19 4 Condom 8 Female (Reality ® ) 21 5 56 Male 14 3 61 Pill 5 71 Progestin Only 0.5 Combined 0.1 IUD Progesterone T 2.0 1.5 81 Copper T380A 0.8 0.6 78 LNg 20 0.1 0.1 81 Depo-Provera ® 0.3 0.3 70 Norplant ® and Norplant-2 ® 0.05 0.05 88 Female Sterilization 0.5 0.5 100 Male Sterilization 0.15 0.10 100 Necon has not been studied for and is not indicated for use in emergency contraception.
