Non-degradable polymers have an important function in medicine. Solid dosage forms for longer term implantation require to be constructed from materials that will not degrade or erode over time and also offer the utmost biocompatibility and biostability. This review details the three most important non-degradable polymers for the production of solid dosage forms - silicone elastomer, ethylene vinyl acetate and thermoplastic polyurethane. The hydrophobic, thermoset silicone elastomer is utilised in the production of a broad range of devices, from urinary catheter tubing for the prevention of biofilm to intravaginal rings used to prevent HIV transmission...

The NuvaRing® is a deformable, ring-shaped hormonal contraceptive device which is typically vaginally self-inserted by the patient. While there are several potential side effects of usage, essentially all of them result from hormone delivery. Complications from incorrect placement are rare. We present the case of a 31 year old female who presented to our emergency department after being unable to retrieve a NuvaRing® for its scheduled removal. CT scan showed a hypodense intravesicular NuvaRing® which the patient had inadvertently placed transurethrally 3 weeks prior...

Intravaginal rings (IVRs) are a dosage form used to locally or systemically deliver drugs in the vagina. They are capable of releasing one or more drugs over an extended period of time (from several weeks to a year or longer). Contraceptive IVRs are currently gaining popularity due to the success of the contraceptive product NuvaRing®. Delivery of contraceptives from IVRs should promote compliance/adherence, and they also provide effective cycle control and symptom relief (menorrhagia, dysmenorrheal, and polycystic ovarian syndrome)...

OBJECTIVE: Epidemiological evidence suggests an association between the use of hormonal contraception and an increased risk of acquiring sexually transmitted diseases including HIV-1. We sought to elucidate the biological mechanisms underlying the effect of hormonal contraception on the immune system. DESIGN: Cross-sectional study. METHODS: To delineate the biological mechanisms underlying the effect of hormonal contraceptives on the immune system, we analyzed the functional capacity of circulating plasmacytoid dendritic cells (pDCs), the distribution of vaginal immune cell populations, and the systemic and genital levels of immune mediators in women using depot medroxyprogesterone acetate (DMPA), NuvaRing, or combined oral contraceptives (COC)...

INTRODUCTION: Multiple studies confirm the safety and efficacy of the combined ethinyl estradiol (EE) and etonogestrel contraceptive vaginal ring (NuvaRing®). Advantages of continuous drug delivery through the vagina compared to oral administration include stable levels of contraceptive steroids without the need for daily drug administration. Although the combined contraceptive vaginal ring (CCVR) avoids the problem of missed pills, clinical data do not support greater efficacy. Vaginal administration avoids first-pass hepatic effects; however, EE is a potent inducer of hepatic globulins regardless of the route of administration...

We present a case of a 27-year-old women admitted to the hospital with migraine and left upper extremity weakness. Subsequent imaging with computed tomography and magnetic resonance angiography/venography demonstrated an acute-appearing central venous sinus thrombosis. Her only risk factor for venous thromboembolism (VTE) was the use of etonogestrel/ethinyl estradiol vaginal contraceptive ring (NuvaRing). The contraceptive ring was removed and the patient was treated according to the current guidelines. She achieved full neurologic recovery at 6 months' follow-up...

INTRODUCTION: Etonogestrel (ENG) is a progestin used in the contraceptive vaginal ring NuvaRing and the subdermal implant Implanon. A sensitive method for measuring ENG is useful for further investigating the progestin's pharmacokinetics with these alternative contraceptive formulations and generating important information about possible continued efficacy or potential failure to remove the subdermal implant. METHODS: Standards and serum samples were spiked with D8-progesterone (internal standard) and subsequently extracted with dichloromethane, dried, and reconstituted in 25% methanol with formic acid...

The objective of the present study was to investigate if temperature can be utilized to accelerate drug release from Nuvaring®, a reservoir type intravaginal ring based on polyethylene vinyl acetate copolymer that releases a constant dose of contraceptive steroids over a duration of 3 weeks. The reciprocating holder apparatus (USP 7) was utilized to determine real-time and accelerated etonogestrel release from ring segments. It was demonstrated that drug release increased with increasing temperature which can be attributed to enhanced drug diffusion...

Exogenous use of hormones leads to different impact on coagulation. Usually estrogen leads to an activation of coagulation, while use of progestogens alone do not. Combined oral contraceptives (COC) differs significantly regarding VTE risk depending on amount of estrogen and type of progestagen: COC containing desogestrol, gestoden or drospirenone in combination with ethinyl-estradiol (EE) (so called 3rd or 4th generation COC) are associated with a higher VTE risk than COC with EE and levonorgestrel or norethisterone (so called 2nd generation COC)...

A vaginal gel containing the antiretroviral tenofovir (TFV) recently demonstrated 39% protection against HIV infection in women. We designed and evaluated a novel reservoir TFV intravaginal ring (IVR) to potentially improve product effectiveness by providing a more controlled and sustained vaginal dose to maintain cervicovaginal concentrations. Polyurethane tubing of various hydrophilicities was filled with a high-density TFV/glycerol/water semisolid paste and then end-sealed to create IVRs. In vitro, TFV release increased with polyurethane hydrophilicity, with 35 weight percent water-swelling polyurethane IVRs achieving an approximately 10-mg/day release for 90 days with mechanical stiffness similar to that of the commercially available NuvaRing...
