How does Cellactose 80 work?

Cellactose 80 is a spray-dried compound consisting of 75 % α-lactose monohydrate [Ph.Eur./USP-NF/JP] and 25 % cellulose powder dry matter. Cellactose 80, designed especially for direct tableting, combines filling and binding properties of the two excipients which have been synergistically combined to an one-body excipient providing better tableting performance at lower cost.

Cellactose 80 is an inovative filler-binder particularly designed and co-processed for direct compression. Cellactose 80 is a spraydried one-body-compound consisting of 75% alpha-lactose monohydrate and 25% cellulose powder. The advantage of copressing is the synergistic effect of both components, i.e. enhanced compressibility of pure lactose and highly increased flowability of cellulose powder. Spraydrying leads to almost spherical particles of Cellactose 80. It is the content of cellulose that is responsible for its excellent binding capacity. Due to the excellent compressibility of Cellactose 80 tablets with good properties can be obtained at low compression forces. The most obvious advantages of Cellactose 80 are compressibility, flowability, stability, adherence capacity, and pleasant taste. Cellactose 80 is mainly used for high-dosage tablet and for herbal formulations. Cellactose 80 shows superior adherence capacity for small sized actives and therefore provides a very good content uniformity.

Cellactose 80 1 spraydried body 75% of α-lactose monohydrate and 25% cellulose powder compounds. The advantage copressing two components, that is pure lactose enhanced the mobility of the compressibility and high-cellulose powder increased synergies. Spraydrying lead almost Cellactose 80 spherical particles. It is the cellulose content is responsible for its good binding capacity. With the performance Cellactose 80 slices good compression, you can get at low compression force. Cellactose 80 The most obvious advantage is that the compressibility, mobility, stability, and the ability to hold and pleasant taste.

The functions about Selenium Sulfide Lotion

Selenium Sulfide Lotion  is a cytostatic agent used to treat dandruff and other conditions of the scalp or skin.  It is made by combining sulfur and selenium catenate. When it is applied directly to the skin, it helps to reduce or eliminate the symptoms that can accompany certain skin disorders, such as dandruff or dermatitis. Selenium sulfide lotion is available as an over-the-counter drug. For severe skin problems, a doctor may prescribe a more potent version of this topical medication. Apply a sufficient amount to cover affected areas of the body. Lather well with a small amount of water. Leave the Selenium Sulfide Lotion   on the skin for 10 minutes. Rinse thoroughly in the shower. Wash hands well after treatment.

Selenium Sulfide Lotion   should be applied according to the directions or a physician's instructions. Over use can cause discoloration to the skin or hair. Jewelry and clothing can also become discolored if it comes in contact with selenium sulfide lotion. Overuse can also cause dry or oily patches on the skin and temporary hair loss. These side effects can usually be eliminated by reducing the amount of lotion used. Selenium sulfide lotion is only meant to be used externally and it can be poisonous if swallowed. It can also cause irritation if it should get into the eyes or nose. Bandages, dressings, or any other type of lotion or cosmetic should never be used along with selenium sulfide lotion.

Tinea versicolor is a fungal infection that can discolor and irritate the skin. It appears on the upper arms, legs, chest, or back. Due to an overgrowth of yeast, it can produce pink, brown, or tan patches of scaly, bumpy skin. Exposure to direct sunlight makes these patches more visible. Using selenium sulfide lotion can reduce or eliminate tinea versicolor and return a normal pigmentation to the skin.

The medical uses about Methoxsalen

Methoxsalen  is used along with controlled ultraviolet light (UVA) to cause a return in skin color in patients with a certain skin condition (vitiligo). Methoxsalen works by making the skin more sensitive to UVA light. This combination helps to increase the number of pigment-producing cells (melanocytes) in the skin.

Methoxsalen  is a drug used to treat psoriasis, eczema, vitiligo, and some cutaneous Lymphomas in conjunction with exposing the skin to sunlight. Methoxsalen is extracted from Ammi majus, a plant of the family Apiaceae. Methoxsalen modifies the way skin cells receive the UVA radiation, allegedly clearing up the disease. The dosage comes in 10 mg tablets, which are taken in the amount of 30 mg 75 minutes before a PUVA (psoralen + UVA) light treatment. The substance is also present in other Apiaceae as well as Rutaceae, for example bergamot oil which is used in many perfumes and aromatherapy oils.

Methoxsalen  is a naturally occurring substance that is reactive to light. It works by enhancing the body's sensitivity to ultraviolet light A (UVA). Methoxsalen is used in combination with UVA light therapy to treat severe psoriasis. Methoxsalen is usually given after other psoriasis medications have been tried without successful treatment of symptoms.

However, Patients with high blood pressure or a history of liver problems are at risk for inflammation and irreparable damage to both liver and skin. The eyes must be protected from UVA radiation. Side effects include nausea, headaches, dizziness, and in rare cases insomnia. Methoxsalen has also been classified as an IARC Group 1 carcinogen (known to cause cancer) but is only cancerous when combined with Ultra Violet-A radiation.
