  • Patent number: 9358241
    Abstract: The present disclosure is drawn to pharmaceutical compositions and oral dosage capsules containing testosterone undecanoate, as well as related methods. The capsule includes a capsule shell and a capsule fill. The capsule fill can include a solubilizer and about 14 wt % to about 35 wt % testosterone undecanoate based on the total capsule fill. The oral dosage capsule is such that when a single oral administration to a male subject of one or more capsules with a total testosterone undecanoate daily dose of about 350 mg to about 650 mg it provides a ratio of serum testosterone Cmax to serum testosterone Cave of about 2.7 or less. In yet another embodiment, a method for providing a serum concentration of testosterone within a target serum testosterone concentration Cave range for a male subject is provided.

  • Patent number: 6680058
    Abstract: Amphipathic lytic peptides are ideally suited to use in a ligand/cytotoxin combination to induce sterility or long-term contraception in mammals. The peptides act directly on cell membranes, and need not be internalized. Administering a combination of gonadotropin-releasing hormone (GnRH) (or a GnRH agonist) and a membrane-active lytic peptide produces long-term contraception or sterilization in mammals in vivo. The compounds are relatively small, and are not antigenic. Lysis of gonadotropes has been observed to be very rapid (on the order of ten minutes.) The two components—the ligand and the lytic peptide—may optionally be administered as a fusion peptide, or they may be administered separately, with the ligand administered slightly before the lytic peptide, to activate cells with receptors for the ligand, and thereby make those cells susceptible to lysis by the lytic peptide.

  • Publication number: 20020103176
    Abstract: A formulation for male contraception comprising a progestin possessing both estrogenic and androgenic properties is remarkably effective for spermatogenesis suppression in males. The progestin Norethisterone (NET), particularly its derivatives Norethisterone acetate and Norethisterone enanthate in sufficient doses induce oligozoospermia or azoospermia in males. Formulations further comprising an androgen, such as a testosterone derivative such as a testosterone ester, particularly testosterone undecanoate, are especially effective male contraceptive formulations.

  • Patent number: 6420336
    Abstract: The present invention provides antiviral proteins, peptides and conjugates, as well as methods of obtaining these agents. The antiviral proteins, peptides and conjugates of the present invention can be used alone or in combination with other antiviral agents in compositions, such as pharmaceutical compositions, to inhibit the infectivity, replication and cytopathic effects of a virus, such as a retrovirus, in particular a human immunodeficiency virus, specifically HIV-1 or HIV-2, in the treatment or prevention of viral infection.

  • Patent number: 6355235
    Abstract: Certain antibody molecules are so stable and so potent at immobilizing sperm as well as the pathogens for sexually transmitted diseases (STDs) that they make possible new prophylactic contraceptive methods: (a) for men, a skin lotion containing antibodies against sperm and against STD pathogens to be applied to the penis and external genitals during sexual activity, thereby delivering prophylactically effective doses of antibodies to virtually all areas of skin and epithelia across which most STDs, including AIDS, are usually transmitted, and, during vaginal intercourse, the penis will deliver a contraceptively reliable dose of the antibodies to the cervical region of the vagina; and (b) for women, intrauterine devices (IUDs) and intravaginal devices (IVDS) that release antibodies into the uterus or into the vagina to provide continuous protection against pregnancy and STDs for periods of months to years.

  • Patent number: 6333058
    Abstract: A process for preparing a spermicidal agent from neem oil includes (a) mixing neem oil with an aliphatic hydrocarbon solvent so that a precipitate forms, and filtering the mixture to separate the filtrate solution from the precipitate; (b) contacting the filtrate solution of step (a) with a polar extractant solvent whereby a spermicidal agent is extracted from the filtrate solution into the polar extractant solvent; and (c) removing solvent from the polar extractant solvent to produce a concentrated solution containing extract a spermicidal agent.

  • Patent number: 6277418
    Abstract: Novel compositions extracted from corn products provide contraceptive and anti-neoplastic activities. Using novel extraction procedures, compositions may be isolated from corn products. For example, a Zea mays plant product is extracted in a first solvent to produce a solvent extract, the solvent extract is dried to produce an extracted solid, the extracted solid is solubilized in a second solvent, the solubilized extract is purified in a chromatographic process, and an active fraction is collected from the chromatographic process. Compositions may be applied to animal bedding or food, and are adaptable to any suitable method of administration. The contraceptive activity of these compositions is effective for both males and females.
