What should I do if I forget a dose?
Remove the old testosterone buccal system and apply a new one as soon as you remember it. If you remember within 8 hours after the usual application time, keep the new system in place until your next scheduled application time. If you remember more than 8 hours after the usual application time, do not remove the new system at the next scheduled application time.
Mechanism Of Action
Endogenous androgens, including testosterone and dihydrotestosterone (DHT), are responsible for the normal growth and development of the male sex organs and for maintenance of secondary sex characteristics. These effects include the growth and maturation of prostate, seminal vesicles, penis and scrotum; the development of male hair distribution, such as facial, pubic, chest and axillary hair; laryngeal enlargement, vocal chord thickening, alterations in body musculature and fat distribution. Testosterone and DHT are necessary for the normal development of secondary sex characteristics.
Male hypogonadism, a clinical syndrome resulting from insufficient secretion of testosterone, has two main etiologies. Primary hypogonadism is caused by defects of the gonads, such as Klinefelter's syndrome or Leydig cell aplasia, whereas secondary hypogonadism is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH, LH).
No pharmacodynamic studies were conducted using Striant.
When applied to the buccal mucosa, Striant releases testosterone, allowing for absorption of testosterone through gum and cheek surfaces that are in contact with the buccal system. Since venous drainage from the mouth is to the superior vena cava, trans-buccal delivery of testosterone circumvents first-pass (hepatic) metabolism.
Following the initial application of Striant, the serum testosterone concentration rises to a maximum within 10-12 hours. The mean maximum (Cmax) and mean average serum total testosterone concentrations for the 12 hour dosing period (Cavg(0-12)) are within the normal physiologic range.
Striant is intended for twice daily dosing. Serum concentrations of testosterone reach steady-state levels after the second dose of twice daily Striant dosing. Following removal of Striant, the serum testosterone concentration decreases to a level below the normal range within 2-4 hours.

Although no specific food effect study was conducted, Phase 3 study results showed that consumption of food and beverage did not significantly affect the absorption of testosterone from Striant.
The effects of toothbrushing, mouth washing, chewing gum and alcoholic beverages on the use and absorption of Striant were not investigated in controlled studies. However, Phase 3 clinical studies permitted patients to do these activities indicating the use of Striant was not significantly affected by these activities.Distribution
Circulating testosterone is chiefly bound in the serum to sex hormone-binding globulin (SHBG) and albumin. Approximately 40% of testosterone in plasma is bound to SHBG, 2% remains unbound (free) and the rest is bound to albumin and other proteins.Metabolism
Testosterone is metabolized to various 17-keto steroids through two different pathways, and the major active metabolites are estradiol and dihydrotestosterone (DHT).
Mean DHT concentrations increased in parallel with testosterone concentrations during Striant treatment. After 24 hours of treatment, mean (SD) DHT serum concentrations was approximately 80 (50) ng/dL. The mean steady-state T/DHT ratio during treatment with Striant ranged approximately 9-12.Excretion
There is considerable variation in the half-life of testosterone as reported in the literature, ranging from ten to 100 minutes. About 90% of a dose of testosterone given intramuscularly is excreted in the urine as glucuronic and sulfuric acid conjugates of testosterone and its metabolites; about 6% of a dose is excreted in the feces, mostly in the unconjugated form. Inactivation of testosterone occurs primarily in the liver.Geriatrics
In patients 65 years of age and older, the total testosterone Cavg(0-24) value was higher by 13% compared to patients < 65 years of age. In addition, the total T to DHT area-under-the curve ratio was lower in the older population compared to the younger population by 16%. These differences may not be clinically significant.
Clinical Trials In Adult Hypogonadal Males
Striant was evaluated in a multicenter, open-label Phase 3 trial in 98 hypogonadal men. In this study, 30 mg of Striant was administered buccally twice daily for 12 weeks. The mean age was 53.6 years (range 20 to 75 years). Overall, 69% of patients were Caucasian, 9% were African-American, 15% were Hispanic, 4% were Asian, and 2% were of another ethnic origin. At baseline, 10% of patients reported current use of tobacco and 42% drank alcohol.
Of 82 patients who completed the trial and had sufficient data for full analysis, 86.6% had mean serum testosterone concentration (Cavg(0-24)) values within the physiologic range (300-1050 ng/dL).
The mean (±SD) time-averaged steady-state daily testosterone concentration (Cavg(0-24)) at Day 84 was 520 (±205) ng/dL compared with a mean of 149 (±99) ng/dL at Baseline. The mean (±SD) maximum testosterone concentration (Cmax) at Day 84 was 970 (±442) ng/dL. At Day 84, the mean percentage of time over the 24-hour sampling period that total testosterone concentrations remained within the normal range of 300-1050 ng/dL was 76%.
Figure 3 shows the mean total testosterone serum concentration versus time curves on Day 84 (after 12 weeks of Striant treatment).
Figure 3: Mean (SD) total testosterone concentration-time curves on Day 84 (after 12 weeks of Striant treatment, n=82)
Mean DHT concentrations increased in parallel with testosterone concentrations, with the total testosterone/DHT ratio (9-12) indicating no alteration in metabolism of testosterone to DHT in testosterone deficient men treated with Striant.
During continuous treatment there was no accumulation of testosterone, and mean total testosterone, free testosterone, and DHT were maintained within their physiologic ranges.

Striant Dosage and Administration
The recommended dosage for Striant is the application of one buccal system (30 mg) to the gum region twice daily; morning and evening (about 12 hours apart).
To ensure proper dosing, serum testosterone concentrations should be measured. Morning, pre-dose serum testosterone concentrations should be measured at 4 to 12 weeks after initiation of therapy to ensure proper serum testosterone concentrations are achieved. Striant therapy should be discontinued if serum testosterone concentrations are consistently outside of the normal range (300 to 1050 ng/dL) despite the use of one buccal system applied twice daily.
Striant should be placed in a comfortable position just above the incisor tooth (on either side of the mouth). With each application, Striant should be rotated to alternate sides of the mouth.
Upon opening the packet, the rounded side surface of the buccal system should be placed against the gum and held firmly in place with a finger over the lip and against the product for 30 seconds to ensure adhesion. Striant is designed to stay in position until removed. If the buccal system fails to properly adhere to the gum or should fall off during the 12-hour dosing interval, the old buccal system should be removed and a new one applied.
If the buccal system falls out of position within the first 8 hours of dosing, replace with a new system and continue for a total of 12 hours from the placement of the first system. If the system falls out of position after 8 hours of dosing, a new buccal system should be applied and it may remain in place for 12 hours then continue with the next regularly scheduled dosing.
Patients should take care to avoid dislodging the buccal system. Patients should check to see if Striant is in place following consumption of food or alcoholic/non-alcoholic beverages. Striant should not be chewed or swallowed. To remove Striant, gently slide it downwards from the gum toward the tooth to avoid scratching the gum. The Striant buccal system should be removed before routine morning and evening oral care is performed, followed by application of a new buccal system.
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug can not be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Twelve Week Clinical Trials in Hypogonadal Men
In the Phase 3, open-label study, 98 patients received Striant for up to 12 weeks. Adverse reactions to Striant reported by ≥1% of patients are listed in Table 1.
|Adverse Reaction||Striant (n=98)|
|Gum or Mouth Irritation||9.2%|
Gum irritation generally resolved in 1 to 8 days. Gum tenderness resolved in 1 to 14 days [see Gum-related adverse events and gum examinations in Adverse Reactions (6.1)].
The following adverse reactions to Striant occurred in 1 patient each: acne, anxiety, breast enlargement, breast pain, buccal mucosal roughening, difficulty in micturition, fatigue, gingivitis, gum blister, gustatory sense diminished, hematocrit increased, lipids serum increased, liver function tests abnormal, nose edema, stinging of lips, and toothache.
There was one additional 12-week study in 12 patients. In this study, additional adverse reactions to Striant and reported by 1 patient each included emotional lability and hypertension.
Long-Term Extension Clinical Trials in Hypogonadal Men
In two extension trials, a total of 117 and 51 patients received Striant for at least 6 months and 1 year, respectively.
Of 117 patients treated for at least 6 months, adverse reactions reported by 1 patient each included: anxiety, buccal inflammation, depression, dry mouth, gum redness, hypertension, infection, medication error, nausea, pruritus, renal function abnormal, stomatitis, taste bitter, taste perversion and toothache. Polycythemia and increased serum prostate specific antigen (PSA) were reported in three and two patients, respectively.
In these two extension studies, a total of 48 patients received Striant for at least 2 years. In these patients, adverse reactions included: gingival recession, lip ulceration, stomatitis, rash, prostate cancer, increased PSA, abdominal pain, diarrhea, hypertension aggravated, headache, nervousness, polycythemia, taste perversion, aggressiveness, hyperlipidemia, peripheral edema, and anxiety.
Gum-related adverse events and gum examinations
In the open-label study, all reported gum-related adverse events were collected and gum examinations were conducted at Baseline and every month thereafter.
A total of 16 patients reported 19 gum-related adverse reactions. Of these, ten patients (10.2%) reported 12 reactions of mild intensity, four patients (4.1%) reported 5 reactions of moderate intensity, and two patients (2.0%) reported 2 reactions of severe intensity. Four patients (4.1%) discontinued treatment with Striant due to gum or mouth-related adverse reactions including two with severe gum irritation, one with mouth irritation, and one with “bad taste in mouth.” Gum irritation generally resolved in 1 to 8 days. Gum tenderness resolved in 1 to 14 days.
Monthly gum examinations were conducted to assess for gingivitis, gum edema, oral lesions, ulcerations or leukoplakia. No cases of ulceration or leukoplakia were observed. No new oral lesions were observed. The incidence of gingivitis and gum edema was not increased during treatment.
In the two extension trials, gum examinations were conducted every 3 months while on treatment. In one of these trials, no patient had a gum abnormality, and in the other trial, moderate gingivitis and mild gum edema were reported by 1 patient each.
In these two extension studies, patient-reported information on Striant gum adherence was collected every 3 months for 1 year. At each visit, 37% to 52% of patients reported problems with Striant adhering to the gum. Circumstances surrounding Striant detachment included eating, drinking and oral care. Hot foods and hot beverages were more likely to be associated with detachment than cold food and cold beverages.
The following adverse reactions have been identified during post approval use of Striant. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: dry mouth, gingival swelling, lip swelling, mouth ulceration, stomatitis, red blood cell increased, dysgeusia, and venous thromboembolism.
You should not use Striant if you have prostate cancer or male breast cancer.
Misuse of testosterone can cause dangerous or irreversible effects. Never use more than your prescribed dose. Do not share this medicine with another person.
Striant should not be used by a woman or a child.
Notify your doctor if you experience nausea; vomiting; swelling of the ankles; changes in skin color; too frequent or prolonged erections; breathing disturbances, including those associated with sleep; yellowing of the skin or eyes; dark colored urine; or problems with urination.
Notify your doctor if a female partner experiences male-pattern baldness, excessive body hair growth, an increase in acne, menstrual irregularities, or signs of masculinity.
Regularly inspect the gum area where the Striant buccal system is applied. Promptly report any changes to your doctor or dentist.
What happens if I miss a dose?
Remove the old tablet and place a new one in your mouth as soon as you remember. Do not use extra medicine to make up the missed dose.
