摘要:
The present invention teaches that daily, cyclical vaginal delivery of progestin may be used to provide regular, predictable withdrawal bleeding during hormone replacement therapy. The present invention also teaches that constant administration of progestin in a water-insoluble, water-swellable cross-linked polycarboxylic acid polymer may be used to maintain amenorrhea. Either regimen is accompanied by a significant decrease in adverse side effects.

The present invention concerns compositions and methods for using a &bgr;-adrenergic agonist for treating endometriosis, for treating infertility, and for improving fertility. The present invention further concerns formulating such a composition or method in such a way as to provide therapeutically sufficient levels of the &bgr;-adrenergic agonist locally while avoiding adverse systematic concentrations in the host, thereby minimizing or avoiding adverse side effects.
摘要:
A bioadhesive composition wherein the active ingredient may be protected from water or the surrounding environment, thereby protecting it from metabolism or from other degradation caused by moisture, enzymes, or pH effects, and making it bioavailable only at a controlled rate. The active ingredient may be protected from moisture during the manufacturing process and more importantly may be protected from moisture and the immediate septic environment until after the patient has applied the composition, and then only at a slow and controlled rate. It is by this process of progressive hydration that the active ingredient remains protected for many hours after administration. It is also by the process of progressive hydration that controlled and sustained release is achieved because only that part of the active ingredient that is the hydrated (aqueous) fraction of the composition is available for absorption (bioavailable).

摘要:
The invention relates to a pharmaceutical composition for relieving pelvic pain or infertility associated with uterine dysrhythmia. The composition includes a locally-administered anti-dysrhythmic treating agent and a bioadhesive extended-release carrier. The composition may be delivered in an extended release formulation that includes a bioadhesive, water-swellable, water-insoluble, cross-linked polycarboxylic acid polymer, such as polycarbophil. The treating agent may be a local anesthetic, such as lidocaine. The invention also relates to a method of treating or preventing pelvic pain, or treating or improving infertility, by inserting a mixture of an anti-dysrhythmic treating agent and a bioadhesive carrier into the vagina of the patient to be treated.

A bioadhesive tablet wherein the active ingredient may be protected from water or the surrounding environment, thereby protecting it from metabolism or from other degradation caused by moisture, enzymes, or pH effects, and making it bioavailable only at a controlled rate. The active ingredient may be protected from moisture during the manufacturing process and more importantly may be protected from moisture and the immediate septic environment until after the patient has applied the tablet, and then only at a slow and controlled rate. It is by this process of progressive hydration that the active ingredient remains protected for many hours after administration. It is also by the process of progressive hydration that controlled and sustained release is achieved because only that part of the active ingredient that is the hydrated (aqueous) fraction of the tablet is available for absorption (bioavailable).
摘要:
The present invention provides a method of treating or reducing ischemia or incidence of cardiovascular events by administering progesterone. Progesterone, unlike synthetic progestins, has been demonstrated to supplement, rather than to decrease, the beneficial effects of estrogen therapy on myocardial ischemia in females.
摘要:
The present invention provides a composition and use of a composition comprising a bioadhesive cross-linked polycarboxylic acid polymer formulation that enables the use of relatively low mounts of anti-STD infectants, such as N-9, to be used to prevent infection by STDs without causing the irritation to genital tissue that often accompanies higher doses of anti-STDs. The bioadhesive polymer maintains greater contact between the anti-STD agent and the infectant for a much greater period of time, enabling a lower concentration to act longer on the infectant, when compared to currently-available commercial applications containing N-9. Such delivery will enable a safe and non-irritating decrease in the risk of infection with STDs, including HIV.
摘要:
A bioadhesive controlled, extended release progressive hydration composition wherein the active ingredient may be protected from water or the surrounding environment, thereby protecting it from metabolism or from other degradation caused by moisture, enzymes, or pH effects, and making it bioavailable only at a controlled rate. The active ingredient may be protected from moisture during the manufacturing process, as necessary or desired, and more importantly may be protected from moisture and the immediate septic environment until well after the patient has applied the composition, and then only at a slow and controlled rate. It is by this process of progressive hydration that the active ingredient remains protected for many hours after administration. It is also by the process of progressive hydration that controlled and sustained release is achieved because only that part of the active ingredient that is the hydrated (aqueous) fraction of the composition is available for absorption (bioavailable).
摘要:
The present invention relates to a delivery system for pharmaceutical compositions relying in part on an ionic interaction to control and facilitate release of the treating agent. More specifically, the invention relates to an extended controlled-release system having an ionic treating agent and an ionic polymer, wherein the polymer is sufficiently ionized to release the treating agent in a controlled manner over an extended period of time and the composition does not require an emulsion system for administering the treating agent.
