II- Processes Relevant to Drug Therapy: Pharma/PK/PD

Drug Phases:

• Phase 1 (Pharmaceutical Phase): Drug taken orally becomes soluble, allowing it to pass through biological membranes. This phase is absent in subcutaneous, IM, and IV administration.
• Phase 2 (Pharmacokinetic Phase): Involves absorption (primarily through the small intestine), distribution, metabolism (biotransformation, mainly in the liver), and excretion.
• Phase 3 (Pharmacodynamic Phase): Refers to the biological or physiological response to the drug.

Pharmaceutics Phase (Dissolution):

This is the initial stage of drug action and involves two steps:

• Disintegration: The breakdown of tablets into smaller particles.
• Dissolution: The dissolving of these smaller particles into gastrointestinal

What Is a Healthy Diet?

A good diet is important for our health and can help us feel our best. No single food contains all the essential nutrients the body needs to stay healthy and work properly. Our diets should contain a variety of different foods to help us get the wide range of nutrients that our bodies require.

Energy Balance for a Healthy Diet

A healthy diet should provide us with the right amount of energy balance, where the calories consumed from the diet equal the calories used by the body. We need these calories for all the functions of the body. Consuming extra calories will cause weight gain.

The Mediterranean Diet

It is a traditional diet originating from the countries bordering the Mediterranean Sea.

Self-Care for Colds and Flu

What do you do to look after yourself when you catch a cold or the flu? In Madrid, during the month of February, it is common for people to catch a cold. Some of them don't take care of themselves.

When I am ill, I take medication for a week, for instance, ibuprofen or antibiotics; these help me to get over the cold. Secondly, I rest in my bed, and I don't go to school to not infect other people. Additionally, it is essential to eat well because some antibiotics can damage your stomach.

All in all, I believe that when one of us has a cold, it is important to take care of ourselves because these can affect you when you are older.

The Unpredictable Fury of Nature

In December 2004, Pat Ralston was enjoying a luxurious stay at a Thai hotel. As he relaxed on the balcony, engrossed in a book, the beach below buzzed with volleyball players. The sun painted a picture of paradise. Suddenly, the idyllic scene dissolved into chaos as a tsunami roared ashore, engulfing the beach and hotel in its watery grip. Pat miraculously survived, but the immense wave left a trail of devastation across Southeast Asia, claiming thousands of lives and reducing buildings and villages to rubble.

Even the seemingly safe haven of a ship offers no guarantee against nature's wrath. In April 2005, the cruise ship Norwegian Dawn encountered a monstrous 21-meter wave near the Bahamas after battling two...

Tilikum's Early Life and Trauma

Blackfish analyzes how Tilikum’s life led up to his violent encounters. Tilikum was captured as a calf off the coast of Iceland, being separated from his family and taken to Sea Land of the Pacific in British Columbia. At Sea Land, Tilikum and the other orcas were placed in a 30 by 20 foot module at night, with barely enough room to float, and with the lights turned off, leaving him in total darkness and no room to swim. Animal specialists interviewed in the film claim that this led to a type of psychosis.

Tilikum's Involvement in Human Deaths

After Sea Land of the Pacific went out of business in 1992, Tilikum was transferred to Sea World, Orlando. Other than Dawn Brancheau’s death, Tilikum played a part in... Continue reading "Tilikum and Blackfish: Trauma of Orcas in Captivity" »
