Some examples of protective coatings for pharmaceuticals are "sustained release" coatings, which delay dissolution of the drug unit or retard release through restricted diffusion, and "enteric" coatings, which provide protection against the acidic condition of the stomach but dissolve quickly in the more pH neutral environment in the intestine. By manipulating the dissolution pH, some amount of regionally selective drug targeting can be achieved (e.g. early release in the duodenum, intermediate release in the jejunum, later release in the ileum, or even the cecum or post-cecum region (colon region). By manipulating the dissolution rate, some control over the rate of drug accumulation in the body can be achieved, in some cases leading to a prolonged interval of pharmaceutical efficacy for drugs with short half-life in the body.

What is the name of the protective coating that forms on sheet lead?
The protective coating that forms on sheet lead is called lead oxide.
What is the protective coating that arthropods molt called?

What special cell that is encased in a tough protective coating is called a?
Is spore.
What is the protective coating on the leaf called?
The cuticle - a waxy layer that protects a leaf's moisture.
A plant organ that consists of an embryo tissues and a protective coating is called?
A plant organ that consists of embryo tissues and a protective coating is called a seed. Seeds serve as a means of reproduction and dispersal for plants, containing the necessary nutrients to support the embryo during its early growth stages. The protective coating, known as the seed coat, helps shield the embryo from environmental hazards and desiccation.
What is the protective coating manufactured by the cell?
The protective coating manufactured by the cell is called the cell membrane. It is a semi-permeable membrane that surrounds the cell and acts as a barrier, controlling the movement of substances in and out of the cell.
Do spores have a protective coating?
Yes, many spores have a protective outer layer called the sporoderm, which helps them withstand harsh environmental conditions such as desiccation, UV radiation, and chemical exposure. This protective coating is essential for the spores to survive and be able to germinate when conditions are favorable.
Why is the coating on a window sometimes called filmy?
The coating on a window is sometimes called filmy because it has a protective filmy covering which should protect it from smearing due to bugs and constant exposure to pollution.
What is the the clear transparent protective coating over the front part of the eye?
The clear transparent protective coating over the front part of the eye is called the cornea. It is responsible for focusing light into the eye and protecting the eye from dust and other particles.
What is the tough white coating of the eye?
The tough white coating of the eye is called the sclera.
Does a virus has an outer protein coat?
A virus has a protective protein coating called the capsid. The capsid is a cover for the genetic material inside, either RNA or DNA.
The capillaries inside bowman's capsules are the?
