Small molecules in human disease treatment

Due to small size they are quickly ingested through the gastrointestinal tract
Small size allows them to easily penetrate cell membranes as they travel through the body.
Can be effective enzyme inhibitors

Small molecules in human disease treatment

Can be allosteric modifiers in the cystol, nuclei and central nervous system due to their small size and normal physiochemical properties.
Can target extracellular proteins or intracellular receptors.
Can precisely regulate target functions in complex biological systems in a dose- and time-dependent manner.

Therapeutics:

Factors to consider in case of small-molecule drug:

1. Small-molecule drugs are nearly always taken as pills. This can give them an edge over larger drugs that require injections.

2. Their size and relative simplicity leave them more exposed to generic competition than larger, complex biologic drugs.

3. A common small molecule drug is acetylsalicylic acid, the active ingredient of Aspirin. In contrast, large molecules, known as biologics or therapeutic proteins, often have to be administered by injection.

4. The hero to fight psoriasis Otezla, a small-molecular drug earned its company almost a billion through all the competitions.

Advancements:

Majority of new drugs and therapeutics starting to grasp the technological advancement of small-molecules. As the days are advancing towards better science and technology, biologists, chemists and all the drug experts are relying on the best usage of small-molecule drugs and therapies. While the immediate-release dosage forms dominate the market today, more specialized and rationalized products incorporating the concepts of drug delivery are being developed to overcome the physicochemical, physiological and pharmacological challenges inherent with the drugs, and to improve the treatment regimens for the patients.
